Michael Danos and Johann Rafelski edited the Pocketbook of Mathematical Functions, published by Verlag Harri Deutsch in 1984. [14] [15] The book is an abridged version of Abramowitz's and Stegun's Handbook, retaining most of the formulas (except for the first and the two last original chapters, which were dropped), but reducing the numerical tables to a minimum, [14] which, by this time, could ...
The 1960s began the way the previous decade had ended for Formula One's rule book with relatively few changes made. However, with the advent of a new breed of innovative and forward thinking designers like Colin Chapman [12] and the beginnings of drivers lobbying for safer racing conditions, [13] the number of rule changes made began to accelerate as the decade came to a close.
Diamond v. Diehr, 450 U.S. 175 (1981), was a United States Supreme Court decision which held that controlling the execution of a physical process, by running a computer program did not preclude patentability of the invention as a whole. [1][2] The high court reiterated its earlier holdings that mathematical formulas in the abstract could not be ...
Bristol 450. The Bristol 450 was a successful sports car racing prototype model, designed in 1953 by Bristol Cars and based on the abortive ERA G-type Formula Two car of 1952. Although most sources state that only three 450s were built, [1] photographic evidence suggests that at least four were in existence at one point in time. [2]
The Taylor knock-out factor, also called Taylor KO factor or TKOF, is a formulaic mathematical approach for evaluating the stopping power of hunting cartridges, developed by John "Pondoro" Taylor in the middle of the 20th century. Taylor, an elephant hunter and author who wrote two books about rifles and cartridges for African hunting, devised ...
Beiji qianjin yaofang ( traditional Chinese: 備急千金要方; simplified Chinese: 备急千金要方; pinyin: Bèijí qiānjīn yàofāng ), [a] literally Essential Formulas Worth a Thousand in Gold for Emergencies, [2] is a Chinese medical text by Tang-dynasty physician Sun Simiao, first published in 652. A sequel was published in 682.
The Builder's Old Measurement formula remained in effect until the advent of steam propulsion. Steamships required a different method of estimating tonnage, because the ratio of length to beam was larger and a significant volume of internal space was used for boilers and machinery. In 1849, the Moorsom System was created in the United Kingdom ...
The series began in 1972 with the introduction of two classes based on 500 cc and 250 cc engine displacement formulas. [5] A 125 cc class was added in 1974. As motocross technology developed, 500 cc two-stroke motocross bikes became too powerful for the average rider and, faced with diminishing numbers of competitors, the AMA discontinued the ...
