... – Bethe-Bloch formula works well (up to above 1MeV for electrons) – But due to the small mass, electron’s energy loss gets complicated • Relativistic corrections take large effect even down to a few keV level • Electron projectiles can transfer large fractions of energies to the atomic electrons the ...

Misconceptions in Cosmology and how to correct them
... The big bang theory that attempts to explain creation of the universe suffers from a major false prediction known as ‘The Problem of the Cosmological Constant’. As presently formulated, according to the string theorist Brian Greene (1999), the theory predicts a rate of expansion 10120 times greater ...

... Example: Depressing the brake pedal in a car pushes on a piston with crosssectional area 3.0 cm2. The piston applies pressure to the brake fluid, which is connected to two pistons, each with area 12.0 cm2. Each of these pistons presses a brake pad against one side of a rotor attached to one of the r ...

... Consider a D-T fueled ICF fusion plant. a. Estimate the fusion burn time (i.e., “disassembly time”) assuming a cryogenic D-T ICF target (~ 1022 atoms/cm3) of 0.5 cm radius (initial value of radius) is compressed by a factor of 103 to 1025 atoms/cm3. Would this time meet the Lawson criterion? b. Sinc ...

... When the elevator is still, the entire force of your weight presses against the scale. When the elevator accelerates downward, you are not pressing as hard on the scale, because the scale is also moving downward. Since the scale measures how hard you are pushing on it, you appear to weigh less. If y ...
