Boltzmann's equation is a probability equation relating the entropy S of an ideal gas to the quantity W, which is the number of microstates corresponding to a given macrostate, where k is Boltzmann's constant (1.38062 x 10^−23 joule/kelvin).

The double slit experiment: on determining the nature of light.

Demonstration of the wave nature of light. Interference patterns observed in a modern-day replica of Thomas Young's double-slit experiment. A coherent beam from either a red (632.8 nm - top panel) or a green (543.4 nm - bottom panel) Helium-Neon laser, is used to illuminate two 25-micron-wide, 75-micron-spaced slits (double-slit). The resulting diffraction patterns are observed at the same distance from the double-slit. Note the fringe spacing is smaller for shorter (green) wavelength.

The IceCube Neutrino Observatory’s sensors are distributed over a volume of roughly one cubic kilometer of clear Antarctic ice. Under the ice

It turns out that if you divide 1 by 998,001 you get all three-digit numbers from 000 to 999 in order. Except for 998.
