In these lectures I present the theory of the Casimir effect, primarily formulated in terms of Green's functions. There is an intimate relation between the Casimir effect and van der Waals forces. Applications to conductors and dielectric bodies of various shapes will be given for the cases of scalar, electromagnetic, and fermionic fields. The dimensional dependence of the effect will be described. Finally, we ask the question: Is there a connection between the Casimir effect and the phenomenon of sonoluminescence?

169. Theory: Parity An overview of Parity in quantum mechanics and of the ways to break quantum mechanical symmetry. http://www2.slac.stanford.edu/vvc/theory/parity.html

Parity Many physics processes have a property known as parity invariance This means that the probability of a particle process occurring is exactly the same as the probability of the same process occurring with the position vectors and directions of travel of all particles reversed. What does it mean to reverse a position vector? Choose any point as your position vector origin and draw a line from the origin to the position of an object. That is the position vector of the object. A parity transformation about that origin would relocate the object at a point found by flipping that position vector so it goes the same distance from the origin but in exactly the opposite direction. It turns up to down, left to right, and front to back! This seems odd because we are used to thinking of up as physically very different from down, but if we reverse everything then the position of the earth changes, too. Consider, for example, a collision of two spheres in space. There would be no way you could tell by looking at a movie whether you were watching an actual collision or a parity reversed simulation of the collision, each would look equally plausible. Parity invariance is true for strong and electromagnetic interactions . This has many consequences for the possible outcomes in decays and scattering events One of the big surprises of the 1950s was the recognition that parity invariance is not true for weak interactions Right- and Left-Handed Particles

Quantum gravity I collaborate with Rodolfo Gambini, of the University of the Republic in Montevideo, Uruguay, our collaboration has been going on since 1990. We coauthored a book "Loops, knots, gauge theories and quantum gravity" in 1996 and have published many papers together. We study the quantization of general relativity using canonical methods. There is a small community pursuing this kind of research, which is complementary to the mainstream approach to quantum gravity: string theory. String theorists believe that one cannot quantize general relativity because it is not a fundamental theory and one has to replace it with string theory in order to quantize it. General relativity will be an "effective" "low energy" theory.

173. Todd's Quantum Intro This page is intended to give an ordinary person a brief overview of the importance and wonder of quantum mechanics. http://www-theory.chem.washington.edu/~trstedl/quantum/quantum.html

Intro to Quantum Mechanics Sigh So please read on, and take a dip in an ocean of information that I find completely invigorating! If the above picture is your idea of an atom, with electrons looping around the nucleus, you are about 70 years out of date. It's time to open your eyes to the modern world of quantum mechanics! The picture below shows some plots of where you would most likely find an electron in a hydrogen atom (the nucleus is at the center of each plot). What is quantum mechanics? Simply put, quantum mechanics is the study of matter and radiation at an atomic level. Why was quantum mechanics developed? In the early 20th century some experiments produced results which could not be explained by classical physics (the science developed by Galileo Galilei, Isaac Newton, etc.). For instance, it was well known that electrons orbited the nucleus of an atom. However, if they did so in a manner which resembled the planets orbiting the sun, classical physics predicted that the electrons would spiral in and crash into the nucleus within a fraction of a second. Obviously that doesn't happen, or life as we know it would not exist. (Chemistry depends upon the interaction of the electrons in atoms, and life depends upon chemistry). That incorrect prediction, along with some other experiments that classical physics could not explain, showed scientists that something new was needed to explain science at the atomic level. If classical physics is wrong, why do we still use it?

PROLOGUE Fifty years later, in an aged and disillusioned retirement, the same child might contemplate that either: The Natural Universe is stupid. GENESIS In the beginning there was a steam engine. It was conceived and developed by two men named Newcomen and Watt. It typically cut the costs of fifty horses, their feed, care and associated manpower. It pumped water out of Cornish tin mines and ran British cotton mills and railways that criss-crossed the populated areas of the earth. No god ever hijacked the human brain as successfully as this phenomenon. The new artisans were exploited even though they had more cleverly developed hands and brains than did the wannabe intellectuals. The latter formed a Cult society, prefixed it with the adjective Royal. These latter-day charlatans published pretentious rules which they called Laws. These fancies became a foundation stone for all future scientific education. This Royal Society never managed to make it a criminal offence to disagree with them but they had effectively hijacked the hijacker. It was a Seduction of the Innocent. Sacrificed to suit the survival needs of a Cult society.

Basilio Catania's Work on Physics, Information Theory Cosmology and Bible vs. Modern Science Foreword My interst in these areas of research came from my engagement in the telecommunication area, which latter has always been my primary area of investigation. My first insight into said subjects occurred between 1979 and 1981, when I gave a series of lectures titled "Man and Communication" or "Man and Compunication," this latter derived from the progressive integration of computers into telecommunication systems. It was suggested to me by the many forms of communications (visual, aural, tactile, etc.) and the increasing capability of machines to exploit the sensing, actuating and processing capabilities of human beings. From about 1985 onward, I extended my knowledge on the above subjects by studying the early forms of communications between human beings, the structure of language and numbers, of human sensors (brain, ear, eye etc.), human actuators (muscles, neurons, synapses, etc.) and human DNA. I also refreshed my knowledge of information theory, with particular regard to the nature of information. The pace towards the origins of mankind and, shortly after, to the origin of the universe (Cosmology) was short. In addition, I could not avoid comparing the scientific theories of Cosmology with the teachings of the Bible (Genesis). Thus, I gave a series of lectures at the

180. A-K_QUANTUM explanation why Planck s mathematical sculpturing works, and why the discontinuity of energy, or quantum , became one of the fundamental theories of physics. http://www.aethro-kinematics.com/w6_quantX.html

It was believed until the turn of the century that the spectrum of electromagnetic waves (heat, light, micro- and radio-waves) was 'continuous'. Since all these waves convey energy, it was believed that energy is also continuous and infinitely divisible. Nevertheless, in studying 'black-body' radiation it was discovered that this is not true. The predictions of classical physics about the energy distribution among the various frequencies were ambiguous. The experimental curve could not be reproduced from any classical laws or equations. Wien's curve was a good approximation for the higher frequencies but it was off for the lower ones, Raleigh's curve was close to the lower ones but predicted an unreal 'ultaviolet catastrophe'. Faced with this conceptual dead-end, Max Planck experimented with the mathematical interpolation of the two wrong equations hoping to derive a new one that reproduced the experimental curve. However, this mathematical sculpturing showed that the experimental curve could not be exactly matched by any formula, without giving up the basic idea that energy is continuous. Planck finally concluded that energy comes in infinitesimally small, minimal 'quantities'.
