For example, a person's height measured with a tape measure might only be precisely known to the nearest centimeter, so should be presented as 1.62 meters rather than 1.6217 meters. If converted to imperial units, this quantity should be rounded to 64 inches or 63.8 inches rather than 63.7795 inches, to clearly convey the precision of the ...
Such triples are necessarily primitive and have the form (2n + 1, 2n 2 + 2n, 2n 2 + 2n +1). This results from Euclid's formula by remarking that the condition implies that the triple is primitive and must verify (m 2 + n 2) - 2mn = 1. This implies (m – n) 2 = 1, and thus m = n + 1.
Many easily stated number problems have solutions that require sophisticated methods, often from across mathematics. A prominent example is Fermat's Last Theorem . This conjecture was stated in 1637 by Pierre de Fermat, but it was proved only in 1994 by Andrew Wiles , who used tools including scheme theory from algebraic geometry , category ...
The same December, it was announced that a $1 billion, 1,700,000-square-foot (160,000 m 2) headquarters for Google would be built in Manhattan's Hudson Square neighborhood. [ 287 ] [ 288 ] Called Google Hudson Square, the new campus is projected to more than double the number of Google employees working in New York City.
The median land area used by US nuclear power stations per 1 GW installed capacity is 1.3 square miles (3.4 km 2). [ 356 ] [ 357 ] To generate the same amount of electricity annually (taking into account capacity factors ) from solar PV would require about 60 square miles (160 km 2 ), and from a wind farm about 310 square miles (800 km 2 ).
Windows 7 Professional and up support up to 2 physical processors (CPU sockets), [131] whereas Windows 7 Starter, Home Basic, and Home Premium editions support only 1. [132] Physical processors with either multiple cores, or hyper-threading , or both, implement more than one logical processor per physical processor.
The first of three programs written for the machine found the highest proper divisor of 2 18 (262,144), a calculation that was known would take a long time to run—and so prove the computer's reliability—by testing every integer from 2 18 − 1 downwards, as division was implemented by repeated subtraction of the divisor.
[11] [12] In a sectionalized mast, insulators in the vertical support members divide the mast into two vertically stacked conductive sections, which are fed in phase by separate feedlines. This increases the proportion of power radiated in horizontal directions and allows the mast to be taller than 0.625 λ {\displaystyle \lambda } without ...
