Ray Solomonoff (July 25, 1926 – December 7, 2009) [1] [2] was an American mathematician who invented algorithmic probability, [3] his General Theory of Inductive Inference (also known as Universal Inductive Inference), [4] and was a founder of algorithmic information theory. [5]
This is a timeline of pure and applied mathematics history.It is divided here into three stages, corresponding to stages in the development of mathematical notation: a "rhetorical" stage in which calculations are described purely by words, a "syncopated" stage in which quantities and common algebraic operations are beginning to be represented by symbolic abbreviations, and finally a "symbolic ...

Ray Solomonoff's notes written during the Workshop, however, say it ran for roughly eight weeks, from about June 18 to August 17. [14] Solomonoff's Dartmouth notes start on June 22; June 28 mentions Minsky, June 30 mentions Hanover, N.H., July 1 mentions Tom Etter. On August 17, Solomonoff gave a final talk. [15]
[8] [9] Islamic mathematics, in turn, developed and expanded the mathematics known to these civilizations. [10] Contemporaneous with but independent of these traditions were the mathematics developed by the Maya civilization of Mexico and Central America , where the concept of zero was given a standard symbol in Maya numerals .
1974: The lithium-ion battery is invented by M. Stanley Whittingham, and further developed in the 1980s and 1990s by John B. Goodenough, Rachid Yazami and Akira Yoshino. It has impacted modern consumer electronics and electric vehicles. [509] 1974: The Rubik's cube is invented by Ernő Rubik which went on to be the best selling puzzle ever. [510]
1934 - Martin Julian Buerger developed the equi-inclination Weissenberg X-ray camera. Buerger invented the precession camera in 1942. [102] 1934 - C. Arnold Beevers and Henry Lipson invented the Beevers–Lipson strip as a calculation aid for Fourier methods for the determination of the crystal structure of CuSO 4.5H 2 O. [103] [104]
At roughly the same time, the Han Chinese and the Romans both invented the wheeled odometer device for measuring distances traveled, the Roman model first described by the Roman civil engineer and architect Vitruvius (c. 80 BC – c. 15 BC). [102] The device was used at least until the reign of emperor Commodus (r.
