Releasing Emotional Energy

Published on Wednesday, July 19th, 2006

When something happens to us, we feel the experience as emotions. The energy we give the emotion is a gauge as to how we are handling the experience. The more energy we expend, the worse the emotion feels. Until we release the energy field surrounding the experience, we become trapped by it. This can last as long as the emotion is being fed. Here is an exercise to release the entire creation.

Close your eyes. Slowly breathe in the experience, and exhale slowly. Feel all of the experience and see it as a cloud expanding as you feel all the emotions surrounding it. Allow the cloud to expand out, infinitely. Continue breathing slowly as you surrender the feelings and the experience, while expanding the cloud out further and further. Release the entire cloud to The Infinite Field of All That Is. Trust that The Field is taking it all as a gift. Feel the peace of The Field and the Love. Everything is perfect as it is.

Repeat this exercise as often as you need to until a release is experienced.

Conservation of Energy

Published on Sunday, February 5th, 2006

Conservation of energy
Conservation of energy is possibly the most important, and certainly the most practically useful of several conservation laws in physics.

The law states that the total inflow of energy into a system must equal the total outflow of energy from the system, plus the change in the energy contained within the system. In other words, energy can be converted from one form to another, but it cannot be created or destroyed.

In thermodynamics, the first law of thermodynamics is a statement of the conservation of energy for thermodynamic systems.

The law of conservation of energy excludes the possibility of perpetuum mobile of the first kind.

Historical development
To understand the significance of the conservation of energy in the context of the development of thermodynamics, see Thermodynamics timeline Edit

Although ancient philosophers as far back as Thales of Miletus had inklings of the first law, it was the German Gottfried Wilhelm Leibniz during 1676-1689 who first attempted a mathematical formulation. Leibniz noticed that in many mechanical systems (of several masses, mi each with velocity vi) the quantity:

was conserved. He called this quantity the vis viva or living force of the system. The principle represents an accurate statement of the approximate conservation of kinetic energy in many situations. However, many physicists were influenced by the prestige of Sir Isaac Newton in England and of René Descartes in France, both of whom had set great store by the conservation of momentum as a guiding principle.

It was largely engineers such as John Smeaton, Peter Ewart, Karl Hotzmann, Gustave-Adolphe Hirn and Marc Séguin who objected that conservation of momentum alone was not adequate for practical calculation and who made use of Leibniz’s principle. The principle was also championed by some chemists such as William Hyde Wollaston.

Members of the academic establishment such as John Playfair were quick to point out that kinetic energy is clearly not conserved. This is obvious to a modern analysis based on the second law of thermodynamics but in the 18th and 19th centuries, the fate of the lost energy was still unknown. Gradually it came to be suspected that the heat inevitably generated by motion was another form of vis viva. In 1783, Antoine Lavoisier and Pierre-Simon Laplace reviewed the two competing theories of vis viva and caloric[1]. Count Rumford’s 1798 observations of heat generation during the boring of cannons added more weight to the view that mechanical motion could be converted into heat. Vis viva now started to be known as energy, after the term was first used in that sense by Thomas Young in 1807.

In a paper Uber die Natur der Warme, published in the Zeitschrift für Physik in 1837, Karl Friedrich Mohr gave one of the earliest general statements of the doctrine of the conservation of energy in the words: “besides the 54 known chemical elements there is in the physical world one agent only, and this is called Kraft [energy]. It may appear, according to circumstances, as motion, chemical affinity, cohesion, electricity, light and magnetism; and from any one of these forms it can be transformed into any of the others.”

A key stage in the development of the modern conservation principle was the demonstration of the mechanical equivalent of heat. The caloric theory maintained that heat could neither be created nor destroyed but conservation of energy entails the contrary principle that heat and mechanical work are interchangeable.

The mechanical equivalence principle was first stated in its modern form by the German surgeon Julius Robert von Mayer.[2] Mayer reached his conclusion on a voyage to the Dutch East Indies, where he found that his patients’ blood was a deeper red because they were consuming less oxygen, and therefore less energy, to maintain their body temperature in the hotter climate. He had discovered that heat and mechanical work were both forms of energy, and later, after improving his knowledge of physics, he calculated a quantitative relationship between them.

Joule’s apparatus for measuring the mechanical equivalent of heatMeanwhile, in 1843 James Prescott Joule independently discovered the mechanical equivalent in a series of experiments. In the most famous, now called the “Joule apparatus”, a descending weight attached to a string caused a paddle immersed in water to rotate. He showed that the gravitational potential energy lost by the weight in descending was equal to the thermal energy (heat) gained by the water by friction with the paddle.

Over the period 1840-1843, similar work was carried out by engineer Ludwig A. Colding though it was little-known outside his native Denmark.

Both Joule’s and Mayer’s work suffered from resistance and neglect but it was Joule’s that, perhaps unjustly, eventually drew the wider recognition.

For the dispute between Joule and Mayer over priority, see Mechanical equivalent of heat: Priority
Drawing on the earlier work of Joule, Sadi Carnot and Émile Clapeyron, in 1847, Hermann von Helmholtz postulated a relationship between mechanics, heat, light, electricity and magnetism by treating them all as manifestations of a single force (energy in modern terms). He published his theories in his book Über die Erhaltung der Kraft (On the Conservation of Force, 1847). The general modern acceptance of the principle stems from this publication.

In 1877, Peter Guthrie Tait claimed that the principle originated with Sir Isaac Newton, based on a creative reading of propositions 40 and 41 of the Philosophiae Naturalis Principia Mathematica. This is now generally regarded as nothing more than an example of Whig history.

Modern physics
With the discovery of special relativity by Albert Einstein, it was found that energy is one component of an energy-momentum 4-vector. Each of the four components (one of energy and three of momentum) of this vector is separately conserved. The relativistic energy of a massive particle contains a term related to its rest mass in addition to its kinetic energy of motion. In the limit of zero kinetic energy (or equivalently in the rest frame of the massive particle), its total energy is related to its rest mass via the famous equation E = mc2. Thus, the rule of conservation of energy was shown to be a special case of a more general rule, the conservation of mass and energy, which is now usually just referred to as conservation of energy.

The conservation of energy can be shown through Noether’s theorem to be the direct consequence of nature possessing the continuous symmetry of time-translation invariance.

Within the realm of quantum mechanics, the product of the uncertainty in the measurement of energy and the uncertainty in the time interval over which the former is measured is bounded below by Planck’s constant divided by two Pi. uncertainty principle.

The first law of thermodynamics
The essence of the First Law of Thermodynamics declares: energy cannot be destroyed. The first law of thermodynamics basically states that an isolated thermodynamic system can store or hold energy and that this internal energy is conserved. Heat is a process by which energy is added to a system from a high-temperature heat source, or lost to a low-temperature heat sink. In addition, energy may be lost by the system when it does mechanical work on its surroundings, or conversely, it may gain energy as a result of work done on it by its surroundings. The first law states that this energy is conserved: The change in the internal energy is equal to the amount added by heating minus the amount lost by doing work on the environment.

Quantum Mechanics

Published on Sunday, September 18th, 2005

I have this definition of Quantum Mechanics (Physics), because the Heisenberg Theory, Schrödinger equations, wave collapse, etc. are scientifially as close as you can get to the spiritual realm. When an intention goes out into the universe (as well as prayer), you are collapsing the wave function, which in turn, creates change. By providing this science, you can get an idea of how this relates to creation and the non-linear, I often refer to on my site. I hope this adds some clarity to ( Spirituality), which is difficult to explain in scientific terms…Myswizard

Quantum mechanics is a fundamental physical theory that extends, corrects and unifies Newtonian mechanics and Maxwellian electromagnetism, at the atomic and subatomic levels. It is the underlying framework of many fields of physics and chemistry, including condensed matter physics, quantum chemistry, and particle physics. The term quantum (Latin, “how much”) refers to the discrete units that the theory assigns to certain physical quantities, such as the energy of an atom at rest (see Figure 1, at right). Fig. 1: The wavefunctions of an electron in a hydrogen atom possessing definite energy (increasing downward: n=1,2,3,…) and angular momentum (increasing across: s, p, d,…). Brighter areas correspond to higher probability density for a position measurement. The angular momentum and energy are quantized, and only take on discrete values like those shown.

Quantum mechanics is a theory of mechanics, a branch of physics that deals with the motion of bodies and associated physical quantities such as energy and momentum. It is a more fundamental theory than Newtonian mechanics, in the sense that it provides accurate and precise descriptions for many phenomena where Newtonian mechanics drastically fails. Such phenomena include the behavior of systems at atomic length scales and below (in fact, Newtonian mechanics is unable to account for the existence of stable atoms), as well as special macroscopic systems such as superconductors and superfluids. The predictions of quantum mechanics have never been disproven after a century’s worth of experiments. Quantum mechanics incorporates at least three classes of phenomena that classical physics cannot account for: (i) the quantization (discretization) of certain physical quantities, (ii) wave-particle duality, and (iii) quantum entanglement. However, in certain situations, the laws of quantum mechanics approximate the laws of classical mechanics to a high degree of precision; this is often expressed by saying that quantum mechanics “reduces” to classical mechanics, and is known as the correspondence principle.

Quantum mechanics can be formulated in either a relativistic or non-relativistic manner. Relativistic quantum mechanics (quantum field theory) provides the framework for some of the most accurate physical theories known, though non-relativistic quantum mechanics is also frequently used for reasons of convenience. We will use the term “quantum mechanics” to refer to both relativistic and non-relativistic quantum mechanics; the terms quantum physics and quantum theory are synonymous. It should be noted, however, that certain authors refer to “quantum mechanics” in the more restricted sense of non-relativistic quantum mechanics.

Most physicists believe that quantum mechanics provides a correct description for the physical world under almost all circumstances. It seems likely that quantum mechanics fails in the vicinity of black holes, or when considering the observable Universe as a whole. In these regimes, quantum mechanics conflicts with the predictions of general relativity, the dominant theory of gravity. The question of compatibility between quantum mechanics and general relativity remains an area of active research.

The foundations of quantum mechanics were established during the first half of the 20th century by Max Planck, Albert Einstein, Niels Bohr, Werner Heisenberg, Erwin Schrödinger, Max Born, John von Neumann, Paul Dirac, Wolfgang Pauli and others. Some fundamental aspects of the theory are still actively studied.

Description of the theory
There are a number of mathematically equivalent formulations of quantum mechanics. One of the oldest and most commonly used formulations is the transformation theory invented by Paul Dirac, which unifies and generalizes the two earliest formulations of quantum mechanics, matrix mechanics (invented by Werner Heisenberg) and wave mechanics (invented by Erwin Schrödinger).

In this formulation, the instantaneous state of a quantum system encodes the probabilities of its measurable properties, or “observables”. Examples of observables include energy, position, momentum, and angular momentum. Observables can be either continuous (e.g., the position of a particle) or discrete (e.g., the energy of an electron bound to a hydrogen atom.)

Generally, quantum mechanics does not assign definite values to observables. Instead, it makes predictions about probability distributions; that is, the probability of obtaining each of the possible outcomes from measuring an observable. Naturally, these probabilities will depend on the quantum state at the instant of the measurement. There are, however, certain states that are associated with a definite value of a particular observable. These are known as “eigenstates” of the observable (”eigen” meaning “own” in German).

A concrete example will be useful here. Let us consider a free particle. Its quantum state can be represented as a wave, of arbitrary shape and extending over all of space, called a wavefunction. The position and momentum of the particle are observables. An eigenstate of position is a wavefunction that is very large at a particular position x, and zero everywhere else. If we perform a position measurement on such a wavefunction, we will obtain the result x with 100% probability. An eigenstate of momentum, on the other hand, has the form of a plane wave. It can be shown that the wavelength is equal to h/p, where h is Planck’s constant and p is the momentum of the eigenstate.

Usually, a system will not be in an eigenstate of whatever observable we are interested in. However, if we measure the observable, the wavefunction will immediately become an eigenstate of that observable. This process is known as wavefunction collapse. If we know the wavefunction at the instant before the measurement, we will be able to compute the probability of collapsing into each of the possible eigenstates. For example, the free particle in our previous example will usually have a wavefunction that is a wave packet centered around some mean position x0, neither an eigenstate of position nor of momentum. When we measure the position of the particle, it is impossible for us to predict with certainty the result that we will obtain. It is probable, but not certain, that it will be near x0, where the amplitude of the wavefunction is large. After we perform the measurement, obtaining some result x, the wavefunction collapses into a position eigenstate centered at x.

Wave functions can change as time progresses. An equation known as the Schrödinger equation describes how wave functions change in time, a role similar to Newton’s second law in classical mechanics. The Schrödinger equation, applied to our free particle, predicts that the center of a wave packet will move through space at a constant velocity, like a classical particle with no forces acting on it. However, the wave packet will also spread out as time progresses, which means that the position becomes more uncertain. This also has the effect of turning position eigenstates (which can be thought of as infinitely sharp wave packets) into broadened wave packets that are no longer position eigenstates.

Some wave functions produce probability distributions that are constant in time. Many systems that are treated dynamically in classical mechanics are described by such “static” wave functions. For example, a single electron in an unexcited atom is pictured classically as a particle moving in a circular trajectory around the atomic nucleus, whereas in quantum mechanics it is described by a static, spherically symmetric wavefunction surrounding the nucleus (Fig. 1). (Note that only the lowest angular momentum states, labelled s, are spherically symmetric).

The time evolution of wave functions is deterministic in the sense that, given a wavefunction at an initial time, it makes a definite prediction of what the wavefunction will be at any later time. During a measurement, the change of the wavefunction into another one is not deterministic, but rather unpredictable, i.e., random.

The probabilistic nature of quantum mechanics thus stems from the act of measurement. This is one of the most difficult aspects of quantum systems to understand. It was the central topic in the famous Bohr-Einstein debates, in which the two scientists attempted to clarify these fundamental principles by way of thought experiments. In the decades after the formulation of quantum mechanics, the question of what constitutes a “measurement” has been extensively studied. Interpretations of quantum mechanics have been formulated to do away with the concept of “wavefunction collapse”; see, for example, the relative state interpretation. The basic idea is that when a quantum system interacts with a measuring apparatus, their respective wavefunctions become entangled, so that the original quantum system ceases to exist as an independent entity. For details, see the article on measurement in quantum mechanics.

Quantum mechanical effects
As mentioned in the introduction, there are several classes of phenomena that appear under quantum mechanics which have no analogue in classical physics. These are sometimes referred to as “quantum effects”.

The first type of quantum effect is the quantization of certain physical quantities. In the example we have given, of a free particle in empty space, both the position and the momentum are continuous observables. However, if we restrict the particle to a region of space (the so-called “particle in a box” problem), the momentum observable will become discrete; it will only take on the values nℏπ/L, where L is the length of the box and ℏ is Planck’s constant divided by 2 π. Such observables are said to be quantized, and they play an important role in many physical systems. Examples of quantized observables include angular momentum, the total energy of a bound system, and the energy contained in an electromagnetic wave of a given frequency.

Another quantum effect is the uncertainty principle, which is the phenomenon that consecutive measurements of two or more observables may possess a fundamental limitation on accuracy. In our free particle example, it turns out that it is impossible to find a wavefunction that is an eigenstate of both position and momentum. This implies that position and momentum can never be simultaneously measured with arbitrary precision, even in principle: as the precision of the position measurement improves, the maximum precision of the momentum measurement decreases, and vice versa. Those variables for which it holds (e.g., momentum and position, or energy and time) are canonically conjugate variables in classical physics.

Another quantum effect is the wave-particle duality. It has been shown that, under certain experimental conditions, microscopic objects like atoms or electrons exhibit particle-like behavior, such as scattering. (”Particle-like” in the sense of an object that can be localized to a particular region of space.) Under other conditions, the same type of objects exhibit wave-like behavior, such as interference. We can observe only one type of property at a time.

Unsolved problems in physics: In the correspondence limit of quantum mechanics: Is there a preferred interpretation of quantum mechanics? How does the quantum description of reality, which includes elements such as the superposition of states and wavefunction collapse, give rise to the reality we perceive?

Another quantum effect is quantum entanglement. In some cases, the wave function of a system composed of many particles cannot be separated into independent wave functions, one for each particle. In that case, the particles are said to be “entangled”. If quantum mechanics is correct, entangled particles can display remarkable and counter-intuitive properties. For example, a measurement made on one particle can produce, through the collapse of the total wavefunction, an instantaneous effect on other particles with which it is entangled, even if they are far apart. (This does not conflict with special relativity because information cannot be transmitted in this way.)

Mathematical formulation
In the mathematically rigorous formulation of quantum mechanics, developed by Paul Dirac and John von Neumann, the possible states of a quantum mechanical system are represented by unit vectors (called “state vectors”) residing in a complex separable Hilbert space (variously called the “state space” or the “associated Hilbert space” of the system.) The exact nature of this Hilbert space is dependent on the system; for example, the state space for position and momentum states is the space of square-integrable functions, while the state space for the spin of a single electron is just the product of two complex planes. Each observable is represented by a densely defined Hermitian (or self-adjoint) linear operator acting on the state space. Each eigenstate of an observable corresponds to an eigenvector of the operator, and the associated eigenvalue corresponds to the value of the observable in that eigenstate. If the operator’s spectrum is discrete, the observable can only attain those discrete eigenvalues.

The time evolution of a quantum state is described by the Schrödinger equation, in which the Hamiltonian, the operator corresponding to the total energy of the system, generates time evolution.

The inner product between two state vectors is a complex number known as a probability amplitude. During a measurement, the probability that a system collapses from a given initial state to a particular eigenstate is given by the square of the absolute value of the probability amplitudes between the initial and final states.

The possible results of a measurement are the eigenvalues of the operator - which explains the choice of Hermitian operators, for which all the eigenvalues are real. We can find the probability distribution of an observable in a given state by computing the spectral decomposition of the corresponding operator. Heisenberg’s uncertainty principle is represented by the statement that the operators corresponding to certain observables do not commute.

The Schrödinger equation acts on the entire probability amplitude, not merely its absolute value. Whereas the absolute value of the probability amplitude encodes information about probabilities, its phase encodes information about the interference between quantum states. This gives rise to the wave-like behavior of quantum states.

It turns out that analytic solutions of Schrödinger’s equation are only available for a small number of model Hamiltonians, of which the quantum harmonic oscillator and the hydrogen atom are the most important representatives. Even the helium atom, which contains just one more electron than hydrogen, defies all attempts at a fully analytic treatment. There exist several techniques for generating approximate solutions.

For instance, in the method known as perturbation theory one uses the analytic results for a simple quantum mechanical model to generate results for a more complicated model related to the simple model by, for example, the addition of a weak potential energy.

Another method is the “semi-classical equation of motion” approach, which applies to systems for which quantum mechanics produces weak deviations from classical behavior. The deviations can be calculated based on the classical motion. This approach is important for the field of quantum chaos.

An alternative formulation of quantum mechanics is Feynman’s path integral formulation, in which a quantum-mechanical amplitude is considered as a sum over histories between initial and final states; this is the quantum-mechanical counterpart of action principles in classical mechanics.

Interactions with other scientific theories
The fundamental rules of quantum mechanics are very broad. They state that the state space of a system is a Hilbert space and the observables are Hermitian operators acting on that space, but do not tell us which Hilbert space or which operators. These must be chosen appropriately in order to obtain a quantitative description of a quantum system. An important guide for making these choices is the correspondence principle, which states that the predictions of quantum mechanics reduce to those of classical physics when a system becomes large. This “large system” limit is known as the classical or correspondence limit. One can therefore start from an established classical model of a particular system, and attempt to guess the underlying quantum model that gives rise to the classical model in the correspondence limit.

When quantum mechanics was originally formulated, it was applied to models whose correspondence limit was non-relativistic classical mechanics. For instance, the well-known model of the quantum harmonic oscillator uses an explicitly non-relativistic expression for the kinetic energy of the oscillator, and is thus a quantum version of the classical harmonic oscillator.

Early attempts to merge quantum mechanics with special relativity involved the replacement of the Schrödinger equation with a covariant equation such as the Klein-Gordon equation or the Dirac equation. While these theories were successful in explaining many experimental results, they had certain unsatisfactory qualities stemming from their neglect of the relativistic creation and annihilation of particles. A fully relativistic quantum theory required the development of quantum field theory, which applies quantization to a field rather than a fixed set of particles. The first complete quantum field theory, quantum electrodynamics, provides a fully quantum description of the electromagnetic interaction.

The full apparatus of quantum field theory is often unnecessary for describing electrodynamic systems. A simpler approach, one employed since the inception of quantum mechanics, is to treat charged particles as quantum mechanical objects being acted on by a classical electromagnetic field. For example, the elementary quantum model of the hydrogen atom describes the electric field of the hydrogen atom using a classical 1/r Coulomb potential. This “semi-classical” approach fails if quantum fluctuations in the electromagnetic field play an important role, such as in the emission of photons by charged particles.

Quantum field theories for the strong nuclear force and the weak nuclear force have been developed. The quantum field theory of the strong nuclear force is called quantum chromodynamics, and describes the interactions of the subnuclear particles: quarks and gluons. The weak nuclear force and the electromagnetic force were unified, in their quantized forms, into a single quantum field theory known as electroweak theory.
It has proven difficult to construct quantum models of gravity, the remaining fundamental force. Semi-classical approximations are workable, and have led to predictions such as Hawking radiation. However, the formulation of a complete theory of quantum gravity is hindered by apparent incompatibilities between general relativity, the most accurate theory of gravity currently known, and some of the fundamental assumptions of quantum theory. The resolution of these incompatibilities is an area of active research, and theories such as string theory are among the possible candidates for a future theory of quantum gravity.

Applications of quantum theory

Quantum mechanics has had enormous success in explaining many of the features of our world. The individual behavior of the microscopic particles that make up all forms of matter - electrons, protons, neutrons, and so forth - can often only be satisfactorily described using quantum mechanics.

Quantum mechanics is important for understanding how individual atoms combine to form chemicals. The application of quantum mechanics to chemistry is known as quantum chemistry. Quantum mechanics can provide quantitative insight into chemical bonding processes by explicitly showing which molecules are energetically favorable to which others, and by approximately how much. Most of the calculations performed in computational chemistry rely on quantum mechanics.

Much of modern technology operates at a scale where quantum effects are significant. Examples include the laser, the transistor, the electron microscope, and magnetic resonance imaging. The study of semiconductors led to the invention of the diode and the transistor, which are indispensable for modern electronics.

Researchers are currently seeking robust methods of directly manipulating quantum states. Efforts are being made to develop quantum cryptography, which will allow guaranteed secure transmission of information. A more distant goal is the development of quantum computers, which are expected to perform certain computational tasks exponentially faster than classical computers. Another active research topic is quantum teleportation, which deals with techniques to transmit quantum states over arbitrary distances.

Philosophical consequences

Since its inception, the many counter-intuitive results of quantum mechanics have provoked strong philosophical debate and many interpretations. Even fundamental issues such as Max Born’s basic rules concerning probability amplitudes and probability distributions took decades to be appreciated.

The Copenhagen interpretation, due largely to Niels Bohr, was the standard interpretation of quantum mechanics when it was first formulated. According to it, the probabilistic nature of quantum mechanics predictions cannot be explained in terms of some other deterministic theory, and do not simply reflect our limited knowledge. Quantum mechanics provides probabilistic results because the physical universe is itself probabilistic rather than deterministic.

Albert Einstein, himself one of the founders of quantum theory, disliked this loss of determinism in measurement. He held that there should be a local hidden variable theory underlying quantum mechanics and consequently the present theory was incomplete. He produced a series of objections to the theory, the most famous of which has become known as the EPR paradox. John Bell showed that the EPR paradox led to experimentally testable differences between quantum mechanics and local hidden variable theories. Experiments have been taken as confirming that quantum mechanics is correct and the real world cannot be described in terms of such hidden variables. “Loopholes” in the experiments, however, mean that the question is still not quite settled.

See the Bohr-Einstein debates

The Everett many-worlds interpretation, formulated in 1956, holds that all the possibilities described by quantum theory simultaneously occur in a “multiverse” composed of mostly independent parallel universes. While the multiverse is deterministic, we perceive non-deterministic behavior governed by probabilities because we can observe only the universe we inhabit.

The Bohm interpretation, formulated by David Bohm, postulates the existence of a non-local, universal wavefunction (Schrödinger equation) which allows distant particles to interact instantaneously. Based on this interpretation, Bohm has speculated that the ultimate nature of physical reality is not a collection of separate objects (as it appears to us), but rather an undivided whole that is in perpetual dynamic flux. However, the Bohm interpretation is not popular among physicists, largely because it is considered very inelegant.
Fritjof Capra has drawn the parallels between Taoist thought and quantum physics in his book, ‘The Tao of Physics’.

History
In 1900, Max Planck introduced the idea that energy is quantized, in order to derive a formula for the observed frequency dependence of the energy emitted by a black body. In 1905, Einstein explained the photoelectric effect by postulating that light energy comes in quanta called photons. In 1913, Bohr explained the spectral lines of the hydrogen atom, again by using quantization. In 1924, Louis de Broglie put forward his theory of matter waves.

These theories, though successful, were strictly phenomenological: there was no rigorous justification for quantization. They are collectively known as the old quantum theory.

The phrase “quantum physics” was first used in Johnston’s Planck’s Universe in Light of Modern Physics.
Modern quantum mechanics was born in 1925, when Heisenberg developed matrix mechanics and Schrödinger invented wave mechanics and the Schrödinger equation. Schrödinger subsequently showed that the two approaches were equivalent.

Heisenberg formulated his uncertainty principle in 1927, and the Copenhagen interpretation took shape at about the same time. Starting around 1927, Paul Dirac unified quantum mechanics with special relativity. He also pioneered the use of operator theory, including the influential bra-ket notation, as described in his famous 1930 textbook. During the same period, John von Neumann formulated the rigorous mathematical basis for quantum mechanics as the theory of linear operators on Hilbert spaces, as described in his likewise famous 1932 textbook. These, like many other works from the founding period still stand, and remain widely used.

The field of quantum chemistry was pioneered by Walter Heitler and Fritz London, who published a study of the covalent bond of the hydrogen molecule in 1927. Quantum chemistry was subsequently developed by a large number of workers, including the American chemist Linus Pauling.

Beginning in 1927, attempts were made to apply quantum mechanics to fields rather than single particles, resulting in what are known as quantum field theories. Early workers in this area included Dirac, Pauli, Weisskopf, and Jordan. This area of research culminated in the formulation of quantum electrodynamics by Feynman, Dyson, Schwinger, and Tomonaga during the 1940s. Quantum electrodynamics is a quantum theory of electrons, positrons, and the electromagnetic field, and served as a role model for subsequent quantum field theories.

The many worlds interpretation was formulated by Everett in 1956.

The theory of quantum chromodynamics was formulated beginning in the early 1960s. The theory as we know it today was formulated by Politzer, Gross and Wilzcek in 1975. Building on pioneering work by Schwinger, Higgs, Goldstone and others, Glashow, Weinberg and Salam independently showed how the weak nuclear force and quantum electrodynamics could be merged into a single electroweak force.

Founding experiments
• Thomas Young’s double-slit experiment proving the wave nature of light (c1805)
• Henri Becquerel discovers radioactivity (1896)
• Joseph John Thomson’s cathode ray tube experiments (discovers the electron and its negative charge) (1897)
• The study of black body radiation between 1850 and 1900, which could not be explained without quantum concepts.
• The photoelectric effect: Einstein explained this in 1905 (and later received a Nobel prize for it) using the concept of photons, particles of light with quantized energy
• Robert Millikan’s oil-drop experiment, which showed that electric charge occurs as quanta (whole units), (1909)
• Ernest Rutherford’s gold foil experiment disproved the plum pudding model of the atom which suggested that the positive charge and mass of the atom are almost uniformly distributed. (1911)
• Otto Stern and Walter Gerlach conduct the Stern-Gerlach experiment, which demonstrates the quantized nature of particle spin (1920)
• Clinton Davisson and Lester Germer demonstrate the wave nature of the electron 1 (1927)

The Universe as a Hologram

Does Objective Reality Exist, or is the Universe a Phantasm?3 SUNS

In 1982 a remarkable event took place. At the University of Paris a research team led by physicist Alain Aspect performed what may turn out to be one of the most important experiments of the 20th century. You did not hear about it on the evening news. In fact, unless you are in the habit of reading scientific journals you probably have never even heard Aspect’s name, though there are some who believe his discovery may change the face of science.

Aspect and his team discovered that under certain circumstances subatomic particles such as electrons are able to instantaneously communicate with each other regardless of the distance separating them. It doesn’t matter whether they are 10 feet or 10 billion miles apart.

Somehow each particle always seems to know what the other is doing. The problem with this feat is that it violates Einstein’s long-held tenet that no communication can travel faster than the speed of light. Since traveling faster than the speed of light is tantamount to breaking the time barrier, this daunting prospect has caused some physicists to try to come up with elaborate ways to explain away Aspect’s findings. But it has inspired others to offer even more radical explanations.

University of London physicist David Bohm, for example, believes Aspect’s findings imply that objective reality does not exist, that despite its apparent solidity the universe is at heart a phantasm, a gigantic and splendidly detailed hologram.

To understand why Bohm makes this startling assertion, one must first understand a little about holograms. A hologram is a three- dimensional photograph made with the aid of a laser. To make a hologram, the object to be photographed is first bathed in the light of a laser beam. Then a second laser beam is bounced off the reflected light of the first and the resulting interference pattern (the area where the two laser beams commingle) is captured on film. When the film is developed, it looks like a meaningless swirl of light and dark lines. But as soon as the developed film is illuminated by another laser beam, a three-dimensional image of the original object appears. The three-dimensionality of such images is not the only remarkable characteristic of holograms. If a hologram of a rose is cut in half and then illuminated by a laser, each half will still be found to contain the entire image of the rose. Indeed, even if the halves are divided again, each snippet of film will always be found to contain a smaller but intact version of the original image. Unlike normal photographs, every part of a hologram contains all the information possessed by the whole. The “whole in every part” nature of a hologram provides us with an entirely new way of understanding organization and order. For most of its history, Western science has labored under the bias that the best way to understand a physical phenomenon, whether a frog or an atom, is to dissect it and study its respective parts.

A hologram teaches us that some things in the universe may not lend themselves to this approach. If we try to take apart something constructed holographically, we will not get the pieces of which it is made, we will only get smaller wholes. This insight suggested to Bohm another way of understanding Aspect’s discovery. Bohm believes the reason subatomic particles are able to remain in contact with one another regardless of the distance separating them is not because they are sending some sort of mysterious signal back and forth, but because their separateness is an illusion. He argues that at some deeper level of reality such particles are not individual entities, but are actually extensions of the same fundamental something.

To enable people to better visualize what he means, Bohm offers the following illustration.
Imagine an aquarium containing a fish. Imagine also that you are unable to see the aquarium directly and your knowledge about it and what it contains comes from two television cameras, one directed at the aquarium’s front and the other directed at its side. As you stare at the two television monitors, you might assume that the fish on each of the screens are separate entities. After all, because the cameras are set at different angles, each of the images will be slightly different. But as you continue to watch the two fish, you will eventually become aware that there is a certain relationship between them. When one turns, the other also makes a slightly different but corresponding turn; when one faces the front, the other always faces toward the side. If you remain unaware of the full scope of the situation, you might even conclude that the fish must be instantaneously communicating with one another, but this is clearly not the case.

This, says Bohm, is precisely what is going on between the subatomic particles in Aspect’s experiment. According to Bohm, the apparent faster-than-light connection between subatomic particles is really telling us that there is a deeper level of reality we are not privy to, a more complex dimension beyond our own that is analogous to the aquarium. And, he adds, we view objects such as subatomic particles as separate from one another because we are seeing only a portion of their reality.

Such particles are not separate “parts”, but facets of a deeper and more underlying unity that is ultimately as holographic and indivisible as the previously mentioned rose. And since everything in physical reality is comprised of these “eidolons”, the universe is itself a projection, a hologram.

In addition to its phantomlike nature, such a universe would possess other rather startling features. If the apparent separateness of subatomic particles is illusory, it means that at a deeper level of reality all things in the universe are infinitely interconnected. The electrons in a carbon atom in the human brain are connected to the subatomic particles that comprise every salmon that swims, every heart that beats, and every star that shimmers in the sky. Everything interpenetrates everything, and although human nature may seek to categorize and pigeonhole and subdivide, the various phenomena of the universe, all apportionments are of necessity artificial and all of nature is ultimately a seamless web.

In a holographic universe, even time and space could no longer be viewed as fundamentals. Because concepts such as location break down in a universe in which nothing is truly separate from anything else, time and three-dimensional space, like the images of the fish on the TV monitors, would also have to be viewed as projections of this deeper order. At its deeper level reality is a sort of superhologram in which the past, present, and future all exist simultaneously. This suggests that given the proper tools it might even be possible to someday reach into the superholographic level of reality and pluck out scenes from the long-forgotten past. What else the superhologram contains is an open-ended question. Allowing, for the sake of argument, that the superhologram is the matrix that has given birth to everything in our universe, at the very least it contains every subatomic particle that has been or will be — every configuration of matter and energy that is possible, from snowflakes to quasars, from blue whales to gamma rays. It must be seen as a sort of cosmic storehouse of “All That Is.”

Although Bohm concedes that we have no way of knowing what else might lie hidden in the superhologram, he does venture to say that we have no reason to assume it does not contain more. Or as he puts it, perhaps the superholographic level of reality is a “mere stage” beyond which lies “an infinity of further development”. Bohm is not the only researcher who has found evidence that the universe is a hologram. Working independently in the field of brain research, Standford neurophysiologist Karl Pribram has also become persuaded of the holographic nature of reality.

Pribram was drawn to the holographic model by the puzzle of how and where memories are stored in the brain. For decades numerous studies have shown that rather than being confined to a specific location, memories are dispersed throughout the brain.

In a series of landmark experiments in the 1920s, brain scientist Karl Lashley found that no matter what portion of a rat’s brain he removed he was unable to eradicate its memory of how to perform complex tasks it had learned prior to surgery. The only problem was that no one was able to come up with a mechanism that might explain this curious “whole in every part” nature of memory storage. Then in the 1960s Pribram encountered the concept of holography and realized he had found the explanation brain scientists had been looking for. Pribram believes memories are encoded not in neurons, or small groupings of neurons, but in patterns of nerve impulses that crisscross the entire brain in the same way that patterns of laser light interference crisscross the entire area of a piece of film containing a holographic image. In other words, Pribram believes the brain is itself a hologram. Pribram’s theory also explains how the human brain can store so many memories in so little space. It has been estimated that the human brain has the capacity to memorize something on the order of 10 billion bits of information during the average human lifetime (or roughly the same amount of information contained in five sets of the Encyclopaedia Britannica).

Similarly, it has been discovered that in addition to their other capabilities, holograms possess an astounding capacity for information storage–simply by changing the angle at which the two lasers strike a piece of photographic film, it is possible to record many different images on the same surface. It has been demonstrated that one cubic centimeter of film can hold as many as 10 billion bits of information. Our uncanny ability to quickly retrieve whatever information we need from the enormous store of our memories becomes more understandable if the brain functions according to holographic principles. If a friend asks you to tell him what comes to mind when he says the word “zebra”, you do not have to clumsily sort back through some gigantic and cerebral alphabetic file to arrive at an answer. Instead, associations like “striped”, “horselike”, and “animal native to Africa” all pop into your head instantly. Indeed, one of the most amazing things about the human thinking process is that every piece of information seems instantly cross- correlated with every other piece of information–another feature intrinsic to the hologram. Because every portion of a hologram is infinitely interconnected with every other portion, it is perhaps nature’s supreme example of a cross-correlated system.

The storage of memory is not the only neurophysiological puzzle that becomes more tractable in light of Pribram’s holographic model of the brain. Another is how the brain is able to translate the avalanche of frequencies it receives via the senses (light frequencies, sound frequencies, and so on) into the concrete world of our perceptions. Encoding and decoding frequencies is precisely what a hologram does best. Just as a hologram functions as a sort of lens, a translating device able to convert an apparently meaningless blur of frequencies into a coherent image, Pribram believes the brain also comprises a lens and uses holographic principles to mathematically convert the frequencies it receives through the senses into the inner world of our perceptions. An impressive body of evidence suggests that the brain uses holographic principles to perform its operations. Pribram’s theory, in fact, has gained increasing support among neurophysiologists.

Argentinian-Italian researcher Hugo Zucarelli recently extended the holographic model into the world of acoustic phenomena. Puzzled by the fact that humans can locate the source of sounds without moving their heads, even if they only possess hearing in one ear, Zucarelli discovered that holographic principles can explain this ability. Zucarelli has also developed the technology of holophonic sound, a recording technique able to reproduce acoustic situations with an almost uncanny realism.

Pribram’s belief that our brains mathematically construct “hard” reality by relying on input from a frequency domain has also received a good deal of experimental support. It has been found that each of our senses is sensitive to a much broader range of frequencies than was previously suspected. Researchers have discovered, for instance, that our visual systems are sensitive to sound frequencies, that our sense of smell is in part dependent on what are now called “osmic frequencies”, and that even the cells in our bodies are sensitive to a broad range of frequencies. Such findings suggest that it is only in the holographic domain of consciousness that such frequencies are sorted out and divided up into conventional perceptions. But the most mind-boggling aspect of Pribram’s holographic model of the brain is what happens when it is put together with Bohm’s theory. For if the concreteness of the world is but a secondary reality and what is “there” is actually a holographic blur of frequencies, and if the brain is also a hologram and only selects some of the frequencies out of this blur and mathematically transforms them into sensory perceptions, what becomes of objective reality?

Put quite simply, it ceases to exist. As the religions of the East have long upheld, the material world is Maya, an illusion, and although we may think we are physical beings moving through a physical world, this too is an illusion.

We are really “receivers” floating through a kaleidoscopic sea of frequency, and what we extract from this sea and transmogrify into physical reality is but one channel from many extracted out of the superhologram. This striking new picture of reality, the synthesis of Bohm and Pribram’s views, has come to be called the holographic paradigm, and although many scientists have greeted it with skepticism, it has galvanized others. A small but growing group of researchers believe it may be the most accurate model of reality science has arrived at thus far. More than that, some believe it may solve some mysteries that have never before been explainable by science and even establish the paranormal as a part of nature.

Numerous researchers, including Bohm and Pribram, have noted that many para-psychological phenomena become much more understandable in terms of the holographic paradigm. In a universe in which individual brains are actually indivisible portions of the greater hologram and everything is infinitely interconnected, telepathy may merely be the accessing of the holographic level. It is obviously much easier to understand how information can travel from the mind of individual ‘A’ to that of individual ‘B’ at a far distance point and helps to understand a number of unsolved puzzles in psychology. In particular, Grof feels the holographic paradigm offers a model for understanding many of the baffling phenomena experienced by individuals during altered states of consciousness.

In the 1950s, while conducting research into the beliefs of LSD as a psychotherapeutic tool, Grof had one female patient who suddenly became convinced she had assumed the identity of a female of a species of prehistoric reptile. During the course of her hallucination, she not only gave a richly detailed description of what it felt like to be encapsuled in such a form, but noted that the portion of the male of the species’s anatomy was a patch of colored scales on the side of its head. What was startling to Grof was that although the woman had no prior knowledge about such things, a conversation with a zoologist later confirmed that in certain species of reptiles colored areas on the head do indeed play an important role as triggers of sexual arousal. The woman’s experience was not unique. During the course of his research, Grof encountered examples of patients regressing and identifying with virtually every species on the evolutionary tree (research findings which helped influence the man-into-ape scene in the movie Altered States). Moreover, he found that such experiences frequently contained obscure zoological details which turned out to be accurate. Regressions into the animal kingdom were not the only puzzling psychological phenomena Grof encountered. He also had patients who appeared to tap into some sort of collective or racial unconscious. Individuals with little or no education suddenly gave detailed descriptions of Zoroastrian funerary practices and scenes from Hindu mythology. In other categories of experience, individuals gave persuasive accounts of out-of-body journeys, of precognitive glimpses of the future, of regressions into apparent past-life incarnations.

In later research, Grof found the same range of phenomena manifested in therapy sessions which did not involve the use of drugs. Because the common element in such experiences appeared to be the transcending of an individual’s consciousness beyond the usual boundaries of ego and/or limitations of space and time, Grof called such manifestations “transpersonal experiences”, and in the late ’60s he helped found a branch of psychology called “transpersonal psychology” devoted entirely to their study. Although Grof’s newly founded Association of Transpersonal Psychology garnered a rapidly growing group of like-minded professionals and has become a respected branch of psychology, for years neither Grof or any of his colleagues were able to offer a mechanism for explaining the bizarre psychological phenomena they were witnessing. But that has changed with the advent of the holographic paradigm. As Grof recently noted, if the mind is actually part of a continuum, a labyrinth that is connected not only to every other mind that exists or has existed, but to every atom, organism, and region in the vastness of space and time itself, the fact that it is able to occasionally make forays into the labyrinth and have transpersonal experiences no longer seems so strange.

The holographic prardigm also has implications for so-called hard sciences like biology. Keith Floyd, a psychologist at Virginia Intermont College, has pointed out that if the concreteness of reality is but a holographic illusion, it would no longer be true to say the brain produces consciousness. Rather, it is consciousness that creates the appearance of the brain — as well as the body and everything else around us we interpret as physical. Such a turnabout in the way we view biological structures has caused researchers to point out that medicine and our understanding of the healing process could also be transformed by the holographic paradigm. If the apparent physical structure of the body is but a holographic projection of consciousness, it becomes clear that each of us is much more responsible for our health than current medical wisdom allows. What we now view as miraculous remissions of disease may actually be due to changes in consciousness which in turn effect changes in the hologram of the body.

Similarly, controversial new healing techniques such as visualization may work so well because in the holographic domain of thought images are ultimately as real as “reality”. Even visions and experiences involving “non-ordinary” reality become explainable under the holographic paradigm. In his book “Gifts of Unknown Things,” biologist Lyall Watson discribes his encounter with an Indonesian shaman woman who, by performing a ritual dance, was able to make an entire grove of trees instantly vanish into thin air. Watson relates that as he and another astonished onlooker continued to watch the woman, she caused the trees to reappear, then “click” off again and on again several times in succession. Although current scientific understanding is incapable of explaining such events, experiences like this become more tenable if “hard” reality is only a holographic projection. Perhaps we agree on what is “there” or “not there” because what we call consensus reality is formulated and ratified at the level of the human unconscious at which all minds are infinitely interconnected.

If this is true, it is the most profound implication of the holographic paradigm of all, for it means that experiences such as Watson’s are not commonplace only because we have not programmed our minds with the beliefs that would make them so. In a holographic universe there are no limits to the extent to which we can alter the fabric of reality. What we perceive as reality is only a canvas waiting for us to draw upon it any picture we want. Anything is possible, from bending spoons with the power of the mind to the phantasmagoric events experienced by Castaneda during his encounters with the Yaqui brujo don Juan, for magic is our birthright, no more or less miraculous than our ability to compute the reality we want when we are in our dreams. Indeed, even our most fundamental notions about reality become suspect, for in a holographic universe, as Pribram has pointed out, even random events would have to be seen as based on holographic principles and therefore determined. Synchronicities or meaningful coincidences suddenly makes sense, and everything in reality would have to be seen as a metaphor, for even the most haphazard events would express some underlying symmetry. Whether Bohm and Pribram’s holographic paradigm becomes accepted in science or dies an ignoble death remains to be seen, but it is safe to say that it has already had an influence on the thinking of many scientists. And even if it is found that the holographic model does not provide the best explanation for the instantaneous communications that seem to be passing back and forth between subatomic particles, at the very least, as noted by Basil Hiley, a physicist at Birbeck College in London, Aspect’s findings “indicate that we must be prepared to consider radically new views of reality”.

Considered together, Bohm and Pribram’s theories provide a profound new way of looking at the world: Our brains mathematically construct objective reality by interpreting frequencies that are ultimately projections from another dimension, a deeper order of existence that is beyond both space and time: The brain is a hologram folded in a holographic universe. For Pribram, this synthesis made him realize that the objective world does not exist, at least not in the way we are accustomed to believing. What is “out there” is a vast ocean of waves and frequencies, and reality looks concrete to us only because our brains are able to take this holographic blur and convert it into the sticks and stones and other familiar objects that make up our world. How is the brain (which itself is composed of frequencies of matter) able to take something as insubstantial as a blur of frequencies and make it seem solid to the touch? “The kind of mathematical process that Bekesy simulated with his vibrators is basic to how our brains construct our image of a world out there,” Pribram states. In other words, the smoothness of a piece of fine china and the feel of beach sand beneath our feet are really just elaborate versions of the phantom limb syndrome.

According to Pribram this does not mean there aren’t china cups and grains of beach sand out there. It simply means that a china cup has two very different aspects to its reality. When it is filtered through the lens of our brain it manifests as a cup. But if we could get rid of our lenses, we’d experience it as an interference pattern. Which one is real and which is illusion? “Both are real to me,” says Pribram, “or, if you want to say, neither of them are real.”

This state of affairs is not limited to china cups. We, too, have two very different aspects to our reality. We can view ourselves as physical bodies moving through space. Or we can view ourselves an a blur of interference patterns enfolded throughout the cosmic hologram. Bohm believes this second point of view might even be the more correct, for to think of ourselves as a holographic mind/brain looking at a holographic universe is again an abstraction, an attempt to separate two things that ultimately cannot be separated.

Do not be troubled if this is difficult to grasp. It is relatively easy to understand the idea of holism in something that is external to us, like an apple in a hologram. What makes it difficult is that in this case we an not looking at the hologram. We are part of the hologram.

The difficulty is also another indication of how radical a revision Bohm and Pribram are trying to make in our way of thinking. But it is not the only radical revision. Pribram’s assertion that our brains construct objects pales beside another of Bohm’s conclusions: that we even construct space and time. The implications of this view are just one of the subjects that will be examined as we explore the effect Bohm and Pribram’s ideas have had on the work of other fields.

The Undivided Wholeness of All Things

As soon as Bohm began to reflect on the hologram he saw that it too provided a new way of understanding order. Like the ink drop in its dispersed state, the interference patterns recorded on a piece of holographic film also appear disordered to the naked eye. Both possess orders that are hidden or enfolded in much the same way that the order in a plasma is enfolded in the seemingly random behavior of each of its electrons. But this was not the only insight the hologram provided.

The more Bohm thought about it the more convinced he became that the universe actually employed holographic principles in its operations, was itself a kind of giant, flowing hologram, and this realization allowed him to crystallize all of his various insights into a sweeping and cohesive whole. He published his first papers on his holographic view of the universe in the early 1970s, and in 1980 he presented a mature distillation of his thoughts in a book entitled _Wholeness and the Implicate Order_. In it he did more than just link his myriad ideas together. He transfigured them into a new way of looking at reality that was as breathtaking as it was radical.

Enfolded Orders and Unfolded Realities

One of Bohm’s most startling assertions is that the tangible reality of our everyday lives is really a kind of projection, like a holographic image. Underlying it is a deeper order of existence, a vast and more primary level of reality that gives birth to all the objects and appearances of our physical world in much the same way that a piece of holographic film gives birth to a hologram. Bohm calls this deeper level of reality the Implicate (which means “enfolded”) order, and he refers to our own level of existence as the explicate, or unfolded, order.

He uses these terms because he sees the manifestation of all forms in the universe as the result of countless enfoldings and unfoldings between these two orders. For example, Bohm believes an electron is not one thing but a totality or ensemble enfolded throughout the whole of space. When an instrument detects the presence of a single electron it is simply because one aspect of the electron’s ensemble has unfolded, similar to the way an ink drop unfolds out of the glycerine, at that particular location. When an electron appears to be moving it is due to a continuous series of such unfoldments and enfoldments.

Put another way, electrons and all other particles are no more substantive or permanent than the form a geyser of water takes as it gushes out of a fountain. They are sustained by a constant influx from the implicate order, and when a particle appears to be destroyed, it is not lost. It has merely enfolded back into the deeper order from which it sprang. A piece of holographic film and the image it generates are also an example of an implicate and explicate order. The film is an implicate order because the image encoded in its interference patterns is a hidden totality enfolded throughout the whole. The hologram projected from the film is an explicate order because it represents the unfolded and perceptible version of the image.

The constant and flowing exchange between the two orders explains how particles, such as the electron in the positronium atom, can shapeshift from one kind of particle to another. Such shiftings can be viewed as one particle, say an electron, enfolding back into the implicate order while another, a photon, unfolds and takes its place. It also explains how a quantum can manifest as either a particle or a wave. According to Bohm, both aspects are always enfolded in a quantum’s ensemble, but the way an observer interacts with the ensemble determines which aspect unfolds and which remains hidden. As such, the role an observer plays in determining the form a quantum takes may be no more mysterious than the fact that the way a jeweller manipulates a gem determines which of its facets become visible and which do not. Because the term hologram usually refers to an image that is static and does not convey the dynamic and ever active nature of the incalculable enfoldings and unfoldings that moment by moment create our universe, Bohm prefers to describe the universe not as a hologram, but as a holomovement.”

The existence of a deeper and holographically organized order also explains why reality becomes nonlocal at the subquantum level. As we have seen, when something is organized holographically, all semblance of location breaks down. Saying that every part of a piece of holographic film contains all the information possessed by the whole is really just another way of saying that the information is distributed nonlocally. Hence, if the universe is organized according to holographic principles, it, too, would be expected to have nonlocal properties.

The Undivided Wholeness of All Things

Most mind-boggling of all are Bohm’s fully developed ideas about wholeness. Because everything in the cosmos is made out of the seamless holographic fabric of the implicate order, he believes it is as meaningless to view the universe as composed of “parts,” as it is to view the different geysers in a fountain as separate from the water out of which they flow. An electron is not an “elementary particle.” It is Just a name given to a certain aspect of the holomovement. Dividing reality up into parts and then naming those parts is always arbitrary a product of convention, because subatomic particles, and everything else in the universe, are no more separate from one another than different patterns in an ornate carpet.

This is a profound suggestion. In his general theory of relativity Einstein astounded the world when he said that space and time are not separate entities, but are smoothly linked and part of a larger whole he called the space-time continuum. Bohm takes this idea a giant step further. He says that everything in the universe is part of a continuum. Despite the apparent separateness of things at the explicate level, everything is a seamless extension of everything else, and ultimately even the implicate and explicate orders blend into each other.

Take a moment to consider this. Look at your hand. Now look at the light streaming from the lamp beside you. And at the dog resting at your feet. you are not merely made of the same things. You are the same thing. One thing. Unbroken. One enormous something that has extended its uncountable arms and appendages into all the apparent objects, atoms, restless oceans, and twinkling stars in the cosmos.

Bohm cautions that this does not mean the universe is a giant undifferentiated mass. Things can be part of an undivided whole and still possess their own unique qualities. To illustrate what he means he points to the little eddies and whirlpools that often form in a river. At a glance such eddies appear to be separate things and possess many individual characteristics such as size, rate, and direction of rotation, et cetera. But careful scrutiny reveals that it is impossible to determine where any given whirlpool ends and the river begins. Thus, Bohm is not suggesting that the differences between “things” is meaningless. He merely wants us to be aware constantly that dividing various aspects of the holomovement into “things” is always an abstraction, a way of making those aspects stand out in our perception by our way of thinking. In attempts to correct this, instead of calling different aspects of the holomovement “things,” he prefers to call them “relatively independent subtotalities.”

Indeed, Bohm believes that our almost universal tendency to fragment the world and ignore the dynamic interconnectedness of all things is responsible for many of our problems, not only in science but in our lives and our society as well. For instance, we believe we can extract the valuable parts of the earth without affecting the whole. We believe it is possible to treat parts of our body and not be concerned with the whole. We believe we can deal with various problems in our society such as crime, poverty, and drug addiction, without addressing the problems in our society as a whole, and so on. In his writings Bohm argues passionately that our current way of fragmenting the world into parts not only doesn’t work, but may even lead to our extinction.

Consciousness as a More Subtle Form of Matter

In addition to explaining why quantum physicists find so many examples of interconnectedness when they plumb the depths of matter, Bohm’s holographic universe explains many other puzzles. One is the effect consciousness seems to have on the subatomic world. As we have seen, Bohm rejects the idea that particles don’t exist until they are observed. But he is not in principle against trying to bring consciousness and physics together. He simply feels that most physicists go about it the wrong way, by once again trying to fragment reality and saying that one separate thing, consciousness, interacts with another separate thing, a subatomic particle.

Because all such things are aspects of the holomovement, he feels it has no meaning to speak of consciousness and matter as interacting. In a sense, the observer is the observed. The observer is also the measuring device, the experimental results, the laboratory, and the breeze that blows outside the laboratory. In fact, Bohm believes that consciousness is a more subtle form of matter, and the basis for any relationship between the two lies not in our own level of reality, but deep in the implicate order. Consciousness is present in various degrees of enfoldment and unfoldment in all matter, which is perhaps why plasmas possess some of the traits of living things. As Bohm puts it, “The ability of form to be active is the most characteristic feature of mind, and we have something that is mindlike already with the electron.”

Similarly, he believes that dividing the universe up into living and nonliving things also has no meaning. Animate and inanimate matter are inseparably interwoven, and life, too, is enfolded throughout the totality of the universe. Even a rock is in some way alive, says Bohm, for life and intelligence are present not only in all of matter, but in “energy,” “space,” “time,” “the fabric of the entire universe,” and everything else we abstract out of the holomovement and mistakenly view as separate things.

The idea that consciousness and life (and indeed all things) are ensembles enfolded throughout the universe has an equally dazzling flip side. Just as every portion of a hologram contains the image of the whole, every portion of the universe enfolds the whole. This means that if we knew how to access it we could find the Andromeda galaxy in the thumbnail of our left hand. We could also find Cleopatra meeting Caesar for the first time, for in principle the whole past and implications for the whole future are also enfolded in each small region of space and time. Every cell in our body enfolds the entire cosmos. So does every leaf, every raindrop, and every dust mote, which gives new meaning to William Blake’s famous poem:

To see a World in a Grain of Sand And a Heaven in a Wild Flower,
Hold Infinity in the palm of your hand And Eternity in an hour.
The Energy of a Trillion Atomic Bombs in Every Cubic Centimeter of Space

If our universe is only a pale shadow of a deeper order, what else lies hidden, enfolded in the warp and weft of our reality? Bohm has a suggestion. According to our current understanding of physics, every region of space is awash with different kinds of fields composed of waves of varying lengths. Each wave always has at least some energy. When physicists calculate the minimum amount of energy a wave can possess, they find that every cubic centimeter of empty space contains more energy than the total energy of all the matter in the known universe!

Some physicists refuse to take this calculation seriously and believe it must somehow be in error. Bohm thinks this infinite ocean of energy does exist and tells us at least a little about the vast and hidden nature of the implicate order. He feels most physicists ignore the existence of this enormous ocean of energy because, like fish who are unaware of the water in which they swim, they have been taught to focus primarily on objects embedded in the ocean, on matter. Bohm’s view that space is as real and rich with process as the matter that moves through it reaches full maturity in his ideas about the implicate sea of energy. Matter does not exist independently from the sea, from so called empty space. It is a part of space. To explain what he means, Bohm offers the following analogy: A crystal cooled to absolute zero will allow a stream of electrons to pass through it without scattering them. If the temperature is raised, various flaws in the crystal will lose their transparency, so to speak, and begin to scatter electrons. From an electron’s point of view such flaws would appear as pieces of “matter” floating in a sea of nothingness, but this is not really the ease. The nothingness and the pieces of matter do not exist independently from one another. They are both part of the same
fabric, the deeper order of the crystal.

Bohm believes the same is true at our own level of existence. Space is not empty. It is full, a plenum as opposed to a vacuum, and is the ground for the existence of everything, including ourselves. The universe is not separate from this cosmic sea of energy, it is a ripple on its surface, a comparatively small “pattern of excitation” in the midst of an unimaginably vast ocean. “This excitation pattern is relatively autonomous and gives rise to approximately recurrent, stable and separable projections into a three-dimensional explicate order of manifestation,” states Bohm. In other words, despite its apparent materiality and enormous size, the universe does not exist in and of itself but is the stepchild of something far vaster and more ineffable. More than that, it is not even a major production of this vaster something but is only a passing shadow, a mere hiccup in the greater scheme of things.

This infinite sea of energy is not all that is enfolded in the implicate order. Because the implicate order is the foundation that has given birth to everything in our universe, at the very least it also contains every subatomic particle that has been or will be; every configuration of matter, energy, life, and consciousness that is possible, from quasars to the brain of Shakespeare, from the double helix, to the forces that control the sizes and shapes of galaxies. And even this is not all it may contain. Bohm concedes that there is no reason to believe the implicate order is the end of things. There may be other undreamed of orders beyond it, infinite stages of further development.

THE HOLOGRAPHIC UNIVERSE _Michael Talbot

“We have to begin to view the Universe as ultimately constituted not of matter and energy, but of pure information!” - Michael Talbot

Meaning is Simultaneously Both Mental and Physical

Our current worldview does not provide us with a context with which to understand PK (psychokinesis ). Bohm believes viewing the universe as a holomovement does provide us with a context. To explain what he means he asks us to consider the following situation. Imagine you are walking down a street late one night and a shadow suddenly looms up out of nowhere. Your first thought might be that the shadow is all assailant and you are in danger. The information contained in this thought will in turn give rise to a range of imagined activities, such as running, being hurt, and fighting. The presence of these imagined activities in your mind, however, is not a purely “mental” process, for they are inseparable from a host of related biological processes, such as excitation of nerves, rapid heart beat, release of adrenaline and other hormones, tensing of the muscles, and so on. Conversely, if your first thought is that the shadow is just a shadow, a different set of mental and biological responses will follow. Moreover, a little reflection will reveal that we react both mentally and biologically to everything we experience.

According to Bohm, the important point to be gleaned from this is that consciousness is not the only thing that can respond to meaning. The body can also respond, and this reveals that meaning is simultaneously both mental and physical in nature. This is odd, for we normally think of meaning as something that can only have an active effect on Subjective reality, on the thoughts inside our heads, not something that can engender a response in the physical world of things and objects. Meaning can thus serve as the link or ‘bridge’ between these two sides of reality,” Bohm states. “This link is indivisible in the sense that information contained in thought, which we feel to be on the ‘mental’ side, is at the same time a neurophysiological, chemical, and physical activity, which is clearly what is meant by this thought on the ‘material’ side.”

Bohm feels that examples of objectively active meaning can be found in other physical processes. One is the functioning of a computer chip. A computer chip contains information, and the meaning of the information is active in the sense that it determines how electrical currents flow through the computer. Another is the behavior of subatomic particles. The orthodox view in physics is that quantum waves act mechanically on a particle, controlling its movement in much the same way that the waves of the ocean might control a Ping-Pong ball floating on its surface. But Bohm does not feel that this view can explain, for example, the coordinateddance of electrons in a plasma any more than the wave motion of water could explain a similarly well-choreographed movement of Ping-Pong balls if such a movement were discovered on the ocean’s surface. He believes the relationship between particle and quantum wave is more like a ship on automatic pilot guided by radar waves. A quantum wave does not push an electron about any more than a radar wave pushes a ship. Rather, it provides the electron with information about its environment which the electron then uses to maneuver on its own.

In other words, Bohm believes that an electron is not only mindlike, but is a highly complex entity, a far cry from the standard view that an electron is a simple, Structureless point. The active use of information by electrons, and indeed by all Subatomic particles, indicates that the ability to respond to meaning is a characteristic not only of consciousness but of all matter. It is this intrinsic commonality, says Bohm, that offers a possible explanation for PK. He states, “On this basis, psychokinesis could arise if the mental processes of one or more people were focused on meanings that were in harmony with those guiding the basic processes of the material systems in which this psychokinesis was to be brought about.”

It is important to note that this kind of psychokinesis would not be due to a causal process, that is, a cause-and-effect relationship involving any of the known forces in physics. Instead, it would be the result of a kind of nonlocal “resonance of meanings,” or a kind of nonlocal interaction similar to, but not the same as, the nonlocal interconnection that allows a pair of twin photons to manifest the same angle of polarization which we saw in chapter 2 (for technical reasons Bohm believes mere quantum nonlocality cannot account for either PK or telepathy, and only a deeper form of nonlocality, a kind of “super”nonlocality”, would offer such an explanation).

Extract from:
THE HOLOGRAPHIC UNIVERSE_ by Michael Talbot

In Part Two of _The Holographic Universe_, “Mind and Body,” Michael Talbot discusses the psychological aspects of the holographic model. According to Bohm, “In a universe in which all things are infinitely interconnected, all consciousnesses are also interconnected. Despite appearances, we are beings without borders. Deep down the consciousness of mankind is one.” (p. 60) The holographic theory, according to the author, can explain many psychological phenomena. Some of these include psychic phenomena, the ability to see “auras”, psychosis, the power of the mind to heal using visualization techniques, effects of placebos on healing, lucid dreaming and altered states of consciousness. The power of the mind is awesome and remains untapped. The author believes that by understanding the holographic model we can learn to access these powers. “In the implicate order, as in the brain itself, imagination and reality are ultimately indistinguishable, and it should therefore come as no surprise to us that images in the mind can ultimately manifest as realities in the physical body.”
