Precision (march)
Precision is the authorized march of Royal Military College of Canada. The RMC band performs Precision on parades for march pasts, on Ex Cadet Weekends for the parade to the Memorial Arch, and on the return, the Cadet Wing sings Tom Gelley’s words to welcome the Ex Cadets to the Parade Square.
History
Precision was composed in 1932 by Denise Chabot, wife of Major C. A. Chabot, a Royal Canadian Artillery officer on staff as professor of French at the College at the time. She earned the degree of Associate of the Royal Conservatory of Music and was the president of the Kingston Music Club.
Precision was inspired by "Madelon", one of the popular marching songs sung and whistled by the cadets marching on their way to the Riding School, and the favourite song of the Class of 1932. Mme Chabot improvised a variation on the song, to represent the cadence of the cadets on the march. The composition starts, “We are the gentlemen cadets of RMC We have sworn to love and serve Her Majesty…”
Precision (statistics)
In statistics, the dual term variability is preferred to the use of precision. Variability is the amount of imprecision.
There can be differences in usage of the term for particular statistical models but, in common statistical usage, the precision is defined to be the reciprocal of the variance, while the precision matrix is the matrix inverse of the covariance matrix.
One particular use of the precision matrix is in the context of Bayesian analysis of the multivariate normal distribution: for example, Bernardo & Smith prefer to parameterise the multivariate normal distribution in terms of the precision matrix rather than the covariance matrix because of certain simplifications that then arise.
History
The term precision in this sense (“mensura praecisionis observationum”) first appeared in the works of Gauss (1809) “Theoria motus corporum coelestium in sectionibus conicis solem ambientium” (page 212). Gauss’s definition differs from the modern one by a factor of 
. He writes, for the density function of a normal random variable with precision h,
Braun
Braun is a common surname, originating from the German word for the color brown. The name is the 22nd most common family name in Germany. Many German emigrants to the United States also changed their name to Brown (see Brown (surname)).
In German, Braun is pronounced [bʁaʊn], roughly similar to the English word "brown." In English, it is often mispronounced as "brawn," as in Carol Mosely Braun. Pronunciation is an individual choice and is hard to guess unless one is in a position to hear the person's name spoken.

Braun (company)
Braun GmbH (German pronunciation: [bʁaʊn], commonly pronounced as "braun" in English), formerly Braun AG, is a German consumer products company based in Kronberg. From 1984 until 2007, Braun was a wholly owned subsidiary of The Gillette Company, which had purchased a controlling interest in the company in 1967. Braun is now a wholly owned subsidiary of Procter & Gamble, which acquired Gillette in 2005. On 16 April 2012, De'Longhi bought perpetual rights to manufacture Braun branded products from Procter & Gamble in the small appliance segment. Procter & Gamble will continue to own the Braun brand.
History
Max Braun, a mechanical engineer, established a small engineering shop in Frankfurt am Main in 1921. In 1923, he began producing components for radio sets. In 1928, the company had grown to such an extent, partly due to the use of certain plastic materials, that it moved to new premises on Idsteiner Strasse.
In 1929, eight years after he started his shop, Max Braun began to manufacture entire radio sets. Soon after, Braun became one of Germany's leading radio manufacturers. This development continued with the launch of one of the first combined radio and record players in 1932.
