The micrometre (SI symbol: μm) is a unit of length in the metric system equal to 10 −6 metres ( 1 / 1 000 000 m = 0. 000 001 m). To help compare different orders of magnitude , this section lists some items with lengths between 10 −6 and 10 −5 m (between 1 and 10 micrometers , or μm).
Tau Ceti's habitable zone—the locations where liquid water could be present on an Earth-sized planet—spans a radius of 0.55–1.16 AU, where 1 AU is the average distance from the Earth to the Sun. [66] Primitive life on Tau Ceti's planets may reveal itself through an analysis of atmospheric composition via spectroscopy, if the composition ...
The VII degree is mistakenly marked twice. [1] Bohlen originally expressed the BP scale in both just intonation and equal temperament. The tempered form, which divides the tritave into thirteen equal steps, has become the most popular form. Each step is 13 √ 3 = 3 1 ⁄ 13 = 1.08818… above the next, or 1200 log 2 (3 1 ⁄ 13) = 146.3 ...
The 600-cell is the fifth in the sequence of 6 convex regular 4-polytopes (in order of complexity and size at the same radius). [a] It can be deconstructed into twenty-five overlapping instances of its immediate predecessor the 24-cell, [5] as the 24-cell can be deconstructed into three overlapping instances of its predecessor the tesseract (8-cell), and the 8-cell can be deconstructed into ...
The equation can be understood as simply the probability that an isoprene unit is NOT a cross-link (1−p x) in N−1 successive units along a chain. Since P(N) decreases with N, shorter chains are more probable than longer ones. Note that the number of statistically independent backbone segments is not the same as the number of isoprene units.

Mikhail Moiseyevich Botvinnik (Russian: Михаи́л Моисе́евич Ботви́нник, romanized: Mikhaíl Moiseyevich Botvínnik) [a] (August 17 [O.S. August 4] 1911 – May 5, 1995) was a Soviet and Russian chess grandmaster who held five world titles in three different reigns.
