Concept2, Inc. is an American manufacturer of rowing equipment and exercise machines based in Morrisville, Vermont. It is best known for its air resistance indoor rowing machines (known as "ergometers" or "ergs"), which are considered the standard training and testing machines for competition rowers and can be found in most gyms .
Pavel Antonovich Shurmei (Belarusian: Павел Антонавіч Шурмей, born 1 September 1976) is a Belarusian rower who competed at two Olympic Games and holds multiple world records on the Concept2 indoor rowing machine. He is one of the Belarusian volunteers of the Kastuś Kalinoŭski Battalion.
The greatest distance rowed in 24 hours is 342 km (212.5 miles) by Hannes Obreno, Pierre de Loof, Tim Brys, Mathieu Foucaud, Thijs Obreno, Giel Vanschoenbeek, Arjan van Belle and Thibaut Schollaert (all Belgians) on the Watersportbaan in Ghent, Belgium, on 2–3 October 2014. All eight participants were members of a student rowing club called ...
In mathematics, the logarithm is the inverse function to exponentiation. That means that the logarithm of a number x to the base b is the exponent to which b must be raised to produce x. For example, since 1000 = 103, the logarithm base of 1000 is 3, or log10 (1000) = 3.
ln (r) is the standard natural logarithm of the real number r. Arg (z) is the principal value of the arg function; its value is restricted to (−π, π]. It can be computed using Arg (x + iy) = atan2 (y, x). Log (z) is the principal value of the complex logarithm function and has imaginary part in the range (−π, π].
Information theory. The number of digits in the binary representation of a positive integer n is the integral part of 1 + log 2 n, i.e.⌊ ⌋ + In information theory, the definition of the amount of self-information and information entropy is often expressed with the binary logarithm, corresponding to making the bit the fundamental unit of information.
The decimal value of the natural logarithm of 2 (sequence A002162 in the OEIS ) is approximately. The logarithm of 2 in other bases is obtained with the formula. The common logarithm in particular is ( OEIS : A007524 ) The inverse of this number is the binary logarithm of 10: ( OEIS : A020862 ). By the Lindemann–Weierstrass theorem, the ...
Log-normal distribution. In probability theory, a log-normal (or lognormal) distribution is a continuous probability distribution of a random variable whose logarithm is normally distributed. Thus, if the random variable X is log-normally distributed, then Y = ln (X) has a normal distribution.
