Lectures. Fundamentals of quantum mechanics. Altvw96. "The Alternate View" columns of John G. Cramer by John G. Cramer At the end of 1998 my wife, daughter, and I attended the Renaissance Weekend at Hilton Head Island, South Carolina. That gathering is an invitation-only assemblage of politicians, pundits, writers, academics, media people, and others including the First Family, which has been described as the world's best new years party. Programming at the Renaissance Weekend is rather like that of an up-scale science fiction convention, except that the panels have far more participants than SF Con panels, with each panelist allowed only a 5-minute "sound bite" to describe his or her take on the subject under discussion.
An investment banker told me later that he was surprised to learn that science had so many unsolved problems. So here's my list of the top seven unsolved problems in physics and astrophysics. . This new understanding raises far more questions then it answers. . However, new clues to the puzzle may be coming. Man lifts a 40-pound wheel with one hand and no effort because it’s spinning.
Electricity generated from water: BlackLight Power announces validation of its scientific breakthrough in energy production. How Time Dilation Makes Sense. Previous home next PDF Michael Fowler, UVa Physics, 12/1/07 “Moving Clocks Run Slow” plus “Moving Clocks Lose Synchronization” plus “Length Contraction” leads to consistency! The object of this exercise is to show explicitly how it is possible for two observers in inertial frames moving relative to each other at a relativistic speed to each see the other’s clocks as running slow and as being unsynchronized, and yet if they both look at the same clock at the same time from the same place (which may be far from the clock), they will agree on what time it shows!
Suppose that in Jack’s frame we have two synchronized clocks C1 and C2 set 18 x 108 meters apart (that’s about a million miles, or 6 light-seconds). Jill’s spaceship, carrying a clock C', is traveling at 0.6c, that is 1.8 x 108 meters per second, parallel to the line C1C2, passing close by each clock. Suppose C' is synchronized with C1 as they pass, so both read zero. What does clock C' (the clock on the ship) read as it passes C2? Chapter 3. Classical physics could not explain the spectra of black bodies. It predicted that the intensity (power emitted at a given wavelength) of emitted light should increase rapidly with decreasing wavelength without limit (the "ultraviolet catastrophe").
In the figure below, the curve labeled "Rayleigh-Jeans law" shows the classically expected behavior. However, the measured spectra actually showed an intensity maximum at a particular wavelength, while the intensity decreased at wavelengths both above and below the maximum. In order to explain the spectra, in 1900 the German physicist Max Planck (1858 - 1947) was forced to make a desperate assumption for which he had no physical explanation. As with classical physics, he assumed the body consisted of vibrating oscillators (which were actually collections of atoms or molecules). E = hf (Planck's formula) In classical physics, the electromagnetic field connects charged particles to each other (see Sections 2.4, 2.6). 3.2. L=h/p 3.3. 3.4.
