We are all time travelers... drifting through time at a steady pace, one moment at a time. In what direction are we moving through time? Or does time move through us? How many dimensions of time are there? Though slightly allegorical, three-dimensional time offers physics new parameters, accounting for conventional and exotic physical phenomena, while maintaining the conservation of energy and symmetry groups found in physical law.  I began playing with the idea that all of physics could be reduced to just interactions between spatial and temporal coordinates. I wondered if inertia and momentum might be composed strictly of temporal components. This would require extra time dimensions. Could inertia or momentum be used as indicators of multi-dimensional time? What about charge, spin, and other properties of matter? Answers to some of these questions appeared to reside in neutrino research, specifically neutrino flavor oscillation.  The universality between Thermodynamics and Temporal Mechanics can reduce the fundamental forces of nature into a single expression, a new equivalence principle, which can be used as the generator for the evolution of time. Once Quantum Mechanics is seen through the lens of three-dimensional time, the EPR paradox looses its mystique. The speed of light may be restricted to a set speed limit within each individual frame of reference, however, frames of reference can undergo periods-of-time at varying rates of the passage-of-time. If the positive side of absolute zero is a state of condensed matter, what is on the negative side of absolute zero? Uncondensed matter?  The anti-matter aspect of the Dirac equations may have been misinterpreted. The convention is to assume that "matter" is composed of "particles" distinctly different from "antimatter" composed of "antiparticles". The assumption of one time dimension locks in this interpretation of the Dirac Equations. However, the uniform production of particles and antipa

Teaching is a professional craft. Thinking that any high-scoring college student could come in and excel demeans it as a profession. No one would consider letting smart English majors perform surgery on low-income patients, or allowing cum laude math majors to do legal work for poor clients.

These puzzles are not for me. Perhaps I'm too right-brained.

It's probably my Engineering background but some of these assume (incorrectly) alot. For example. "A man is lying dead in a room. There is a large pile of gold and jewels on the floor, a chandelier attached to the ceiling, and a large open window." "Lying" leads one to believe the man is being held down by weight. If we assume he properly set his ballasts for zero/neutral buoyancy he would be floating especially given his now empty tank. Also most wreckage divers use some form of balloon or cabling system attached to a boat to help "carry" heavy loads to the surface. So he wouldn't have been held down by the find. Finally, only the most experienced divers, with the proper training dive for salvage. An experience diver would never be caught out with no air. Not to mention the problems states there is an easy access path with the "large window" so even if things went completely wrong, the diver could have at least tried for the surface. I'm with Sigrid, not for me. ;-)
