Extractions: Ch. 3 ... Hector Parr's Home Page The behaviour of atomic and sub-atomic particles is well described by Quantum Theory, and scientists engaged in research in this field can use the theory to make predictions of quite remarkable accuracy. But any attempt to understand the philosophy underlying the theory leads to puzzling contradictions. During the twentieth century, several physicists with a thorough understanding of the theory have tried to resolve these conceptual difficulties, but no proposed solution seems wholly satisfactory, and each contains elements which are barely credible. This book examines the writings of some of these scientist-philosophers, and makes one more attempt to get to the root of the problem. The writer believes that a failure to understand the true nature of Time lies at the heart of the difficulties, and he makes one new suggestion, which he calls the Nodal Hypothesis, in an attempt to resolve them. The book shows that several deductions from this hypothesis agree well with observation, and it outlines the direction in which future research may be able to confirm that it is indeed a step in the right direction.

It explains and quantifies three effects that classical physics cannot account for: The values of some measurable variables of a system, most notably the total energy of a bounded system, can attain only certain discrete values determined by the system. (The smallest possible jumps in the values of those observables are called "quanta" (Latin quantum, quantity), hence the name quantum mechanics.

Extractions: Abstract Quantum theory is generally regarded as one of the most successful scientific theories ever formulated. But while the mathematical description of the quantum world allows the probabilities of experimental results to be calculated with a high degree of accuracy, there is no consensus on what it means in conceptual terms. Some of the issues involved are explored below. According to the uncertainty principle, the position and momentum of a subatomic particle cannot be measured simultaneously with an accuracy greater than that set by Planck's constant. This is because in any measurement a particle must interact with at least one photon, or quantum of energy, which acts both like a particle and like a wave, and disturbs it in an unpredictable and uncontrollable manner. An accurate measurement of the position of an orbiting electron by means of a microscope, for example, requires the use of light of short wavelengths, with the result that a large but unpredictable momentum is transferred to the electron. An accurate measurement of the electron's momentum, on the other hand, requires light quanta of very low momentum (and therefore long wavelength), which leads to a large angle of diffraction in the lens and a poor definition of the position.

Extractions: A Lazy Layman's Guide to Quantum Physics James Higgo 1999 What is Quantum Physics? That's an easy one: it's the science of things so small that the quantum nature of reality has an effect. Quantum means 'discrete amount' or 'portion'. Max Planck discovered in 1900 that you couldn't get smaller than a certain minimum amount of anything. This minimum amount is now called the Planck unit. Why is it weird? Niels Bohr, the father of the orthodox 'Copenhagen Interpretation' of quantum physics once said, "Anyone who is not shocked by quantum theory has not understood it". To understand the weirdness completely, you just need to know about three experiments: Light Bulb, Two Slits, Schroedinger's Cat. Two Slits The simplest experiment to demonstrate quantum weirdness involves shining a light through two parallel slits and looking at the screen. It can be shown that a single photon (particle of light) can interfere with itself, as if it travelled through both slits at once. Light Bulb Imagine a light bulb filament gives out a photon, seemingly in a random direction. Erwin Schroedinger came up with a nine-letter-long equation that correctly predicts the chances of finding that photon at any given point. He envisaged a kind of wave, like a ripple from a pebble dropped into a pond, spreading out from the filament. Once you look at the photon, this 'wavefunction' collapses into the single point at which the photon really is. Schroedinger's Cat In this experiment, we take your pet cat and put it in a box with a bottle of cyanide. We rig it up so that a detector looks at an isolated electron and determines whether it is 'spin up' or 'spin down' (it can have either characteristic, seemingly at random). If it is 'spin up', then the bottle is opened and the cat gets it. Ten minutes later we open the box and see if the cat is alive or dead. The question is: what state is the cat in between the detector being activated and you opening the box. Nobody has actually done this experiment (to my knowledge) but it does show up a paradox that arises in certain interpretations.

It is done in a manner which provides an intuitive interpretation of both repulsion and "attraction" and offers a new insight into the stochasitic anisotropic nature of the electrodynamic braking action of bremsstrahlung. Installed on 30 June 30 1997 - Latest update - 5 September 2002 Keywords: Attraction, Bremsstrahlung, Push gravity, Repulsion, Stochastic electrodynamics This exposition is about a Newtonian interpretation of electrical attraction and repulsion. It is dedicated to the memory of Glenn Donald Bryant, of Starkville Mississippi, who quested for causality in modern physics. Part 1 Much of the material will deal with things we cannot measure but the concepts can be modeled on a computer and the statistics from the model's history can be compared to experimental observations. For example, shown here are some results of multiple runs of a program called

Extractions: quantum mechanics or quantum theory, branch of mathematical physics that deals with the emission and absorption of energy by matter and with the motion of material particles. Because it holds that energy and matter exist in tiny, discrete amounts, quantum mechanics is particularly applicable to ELEMENTARY PARTICLES and the interactions between them. According to the older theories of classical physics, energy is treated solely as a continuous phenomenon (i.e., WAVES by Max PLANCK , who proposed that the energies of any harmonic oscillator , such as the atoms of a blackbody radiator, are restricted to certain values, each of which is an integral (whole number) multiple of a basic minimum value. In 1905 Albert EINSTEIN proposed that the radiation itself is also quantized, and he used the new theory to explain the PHOTOELECTRIC EFFECT. Niels BOHR used the quantum theory in 1913 to explain both atomic structure and atomic spectra, showing the connection between the energy levels of an atom's electrons and the frequencies of light matrix uncertainty principle , enunciated by Heisenberg in 1927, which places an absolute theoretical limit on the accuracy of certain measurements; as a result, the assumption by earlier scientists that the physical state of a system could be measured exactly and used to predict future states had to be abandoned. Other developments of the theory include quantum statistics, presented in one form by Einstein and S.N. Bose (Bose-Einstein statistics, which apply to BOSONS) and in another by Dirac and Enrico FERMI (Fermi-Dirac statistics, which apply to FERMIONS); quantum electronics, which deals with interactions involving quantum energy levels and

Extractions: Home Page of Peggy E. Schweiger Discovery of the Electron At the end of the nineteenth century, studies were being conducted in which electricity ws discharged through rarefied gases. In one experiment, a very high voltage was applied to the electrodes of an almost completely evacuated glass tube fitted with electrodes. A dark space was observed to originate at the cathode and extend to the anode at the opposite end and that the far end of the tube would glow. The stream could be deflected by magnetec or electric fields. This stream was given the name cathode rays. In 1897, J.J. Thomson directly measured the q/m (the charge to mass ratio of the cathode rays). He used a high voltage to accelerate the cathode rays and passed them through an electric field produced between two charged parallel plates. A pair of coils produced a magnetic field. The deflection of the particles in the presence of only an electric field or in the prescence of only a magnetic field were consistent with the paths of a negatively-charged particle. In the absence of an electric field, the magnetic force on the particles (F=qvB) bends the rays into a circle, whose radius could be measured. Since F = ma qvB = mv /r or q/m = v/Br Next, the electric field was adjusted so that no deflection due to the magnetic field occurred. Thus, the electric field force (E = F/q) is equal to the magnetic field force (F = qvB).

Extractions: It is important to emphasise that the mathematical equations of quantum physics do not describe actual existence - they predict the potential for existence. Working out the equations of quantum mechanics for a system composed of fundamental particles produces a range of potential locations, values and attributes of the particles which evolve and change with time. But for any system only one of these potential states can become real, and - this is the revolutionary finding of quantum physics - what forces the range of the potentials to assume one value is the act of observation. Matter and energy are not in themselves phenomena, and do not become phenomena until they are observed. The following experiments give some feel for the interaction of mind with matter at the fundamental level of existence:
