A microsecond is a unit of time in the International System of Units (SI) equal to one millionth (0.000001 or 10 −6 or 1 ⁄ 1,000,000) of a second. Its symbol is μs, sometimes simplified to us when Unicode is not available. A microsecond is to one second, as one second is to approximately 11.57 days.
[70] [71] American physical chemists Gilbert N. Lewis and Richard C. Tolman used two variations of the formula in 1909: m = E / c 2 and m 0 = E 0 / c 2 , with E being the relativistic energy (the energy of an object when the object is moving), E 0 is the rest energy (the energy when not moving), m is the relativistic mass (the ...
An amount of light more typical in everyday experience (though much larger than the smallest amount perceivable by the human eye) is the energy of one mole of photons; its energy can be computed by multiplying the photon energy by the Avogadro constant, N A = 6.022 140 76 × 10 23 mol −1, [37] with the result of 216 kJ, about equal to the ...
Ultimately, Bush won 271 electoral votes, one vote more than the 270 required to win, while Gore won the popular vote by 543,895 votes (a margin of 0.52% of all votes cast). [10] Bush flipped 11 states that had voted Democratic in 1996 : Arkansas, Arizona, Florida, Kentucky, Louisiana, Missouri, Nevada, New Hampshire, Ohio, Tennessee, and West ...
The Olduvai Theory posits that industrial civilization, as it currently exists, will have a maximum duration of approximately one hundred years, beginning in 1930. . According to this theory, from 2030 onward, humanity is expected to gradually regress to levels of civilization comparable to those experienced in the past, ultimately culminating in a hunting-based culture by around 3

Suppose also that inflation had halved the value of its currency over that period. To meaningfully compare its GDP in 2000 to its GDP in 1990, we could multiply the GDP in 2000 by one-half, to make it relative to 1990 as a base year. The result would be that the GDP in 2000 equals $300 million × 1 ⁄ 2 = $150 million, in 1990 monetary terms.
