The duplex rule was invented by William Cox in 1891 and was produced by Keuffel and Esser Co. of New York. [ 16 ] [ 17 ] In 1881, the American inventor Edwin Thacher introduced his cylindrical rule, which had a much longer scale than standard linear rules and thus could calculate to higher precision, about four to five significant digits.
The idea of logarithms was also used to construct the slide rule (invented around 1620–1630), which was ubiquitous in science and engineering until the 1970s. A breakthrough generating the natural logarithm was the result of a search for an expression of area against a rectangular hyperbola , and required the assimilation of a new function ...
William Oughtred (5 March 1574 – 30 June 1660), [1] also Owtred, Uhtred, etc., was an English mathematician and Anglican clergyman. [2] [3] [4] After John Napier discovered logarithms and Edmund Gunter created the logarithmic scales (lines, or rules) upon which slide rules are based, Oughtred was the first to use two such scales sliding by one another to perform direct multiplication and ...
A slide rule scale is a line with graduated markings inscribed along the length of a slide rule used for mathematical calculations. The earliest such device had a single logarithmic scale for performing multiplication and division, but soon an improved technique was developed which involved two such scales sliding alongside each other.
The company produced the 4139 Cooke Radio Slide Rule, designed in the mid-1930s by Nelson M. Cooke, of the Navy's Radio Materiel School, thousands of which were made. The K&E 4081-3 Log-Log Duplex Decitrig was a mainstay for engineering students and practicing engineers in the 1940s, 50s, and 60s. [ 8 ]
New York did pass a law in 2022 allowing sexual assault victims to file civil suits, but the lawsuit that eventually yielded the $83.3 million award was filed by Carroll in 2019.
A federal appeals court revived Sarah Palin’s libel case against The New York Times on Wednesday, citing errors by a lower court judge, particularly his decision to dismiss the lawsuit while a ...
