Bill Nye and the Discovery Channel give you the greatest discoveries in physics. Nye explores how the universe operates and why things move and work the way they do. He also explains the second law of thermodynamics, electromagnetism, and how superconductors can help accelerate particles to near the speed of light.
He illustrates Albert Einstein's theory that clocks tick slower at the speed of light and even on an airplane, and discusses how E=MC2 helped develop nuclear power, the quantum leap, the power of electromagnetic energy, the structure of an atom, and the subatomic particles known as quarks.
"Magnetohydrodynamics, or MHD, is a branch of the science of the dynamics of matter moving in an electromagnetic field, especially where currents established in the matter by induction modify the field, so that the field and dynamics equations are coupled."
"A new study on cellphone safety has found that carrying a phone in a shirt or pants pocket exceeds radiation exposure guidelines spelled out by the the Federal Communications Commission (FCC), and that children absorb twice as much cellphone radiation as adults.
The study published in the journal Electromagnetic Biology and Medicine criticizes the way phone manufacturers measure levels of microwave radiation, and calls for the industry standard to be scrapped."
"A major breakthrough in remote wave sensing by a team of Rensselaer Polytechnic Institute researchers opens the way for detecting hidden explosives, chemical, biological agents and illegal drugs from a distance of 20 meters."
