The first Soviet scientific pocket-sized calculator the "B3-18" was completed by the end of 1975. In 1973, Texas Instruments (TI) introduced the SR-10, (SR signifying slide rule) an algebraic entry pocket calculator using scientific notation for $150. Shortly after the SR-11 featured an added key for entering pi (π).
Log-log plot of x + 1 and max (x, 1) from x = 0.001 to 1000 [85] The maximum operation "max ( a , b )" is a binary operation similar to addition. In fact, if two nonnegative numbers a and b are of different orders of magnitude , then their sum is approximately equal to their maximum.
Example: To find 0.69, one would look down the rows to find 0.6 and then across the columns to 0.09 which would yield a probability of 0.25490 for a cumulative from mean table or 0.75490 from a cumulative table. To find a negative value such as -0.83, one could use a cumulative table for negative z-values [3] which yield a probability of 0.20327.
The Sinclair Scientific Programmable was introduced in August 1975, and was larger than the Sinclair Scientific, at 73 by 155 by 34 millimetres (2.9 in × 6.1 in × 1.3 in). [ 7 ] [ 8 ] It was advertised as "the first ... calculator to offer a ... programming facility ... at a price within the reach of the general public," but was limited by ...
Gottfried Wilhelm Leibniz or Leibnitz [a] (1 July 1646 [O.S. 21 June] – 14 November 1716) was a German polymath active as a mathematician, philosopher, scientist and diplomat who is credited, alongside Sir Isaac Newton, with the creation of calculus in addition to many other branches of mathematics, such as binary arithmetic, and statistics.
An example depicting the power of quantum computing is Grover's algorithm for searching unstructured databases. The algorithm's quantum query complexity is O ( N ) {\textstyle O{\left({\sqrt {N}}\right)}} , a quadratic improvement over the best possible classical query complexity O ( N ) {\displaystyle O(N)} , which is a linear search .
Leonardo Torres Quevedo (Spanish: [leoˈnaɾðo ˈtores keˈβeðo]; 28 December 1852 – 18 December 1936) was a Spanish civil engineer, mathematician and inventor, known for his numerous engineering innovations, including aerial trams, airships, catamarans, and remote control.
In an interactive log-file browser, the right thing to do might be to return the entry unparsed, so the user can see it—but in an automated log-summarizing program, the right thing to do might be to supply null values for the unreadable fields, but abort with an error, if too many entries have been malformed.
