Solomon Wolf Golomb (born May 30, 1932) is an American mathematician, engineer and professor of electrical engineering at the University of Southern California, best known for his works on mathematical games. Most notably he invented Cheskers in 1948 and coined the name. He also fully described polyominoes and pentominoes in 1953.〔(Eric Harshbarger - Pentominoes )〕〔(people.rit.edu - Introduction - polyomino and pentomino )〕 He has specialized in problems of combinatorial analysis, number theory, coding theory and communications. His game of pentomino inspired Tetris. == Academic achievements == Golomb, a graduate of the Baltimore City College high school, received his bachelor's degree from Johns Hopkins University and master's and doctorate degree in mathematics from Harvard University in 1957 with a dissertation on "Problems in the Distribution of the Prime Numbers". While working at the Glenn L. Martin Company he became interested in communications theory and began his work on shift register sequences. He spent his Fulbright year at the University of Oslo and then joined the Jet Propulsion Laboratory at Caltech, where he researched military and space communications. He joined the faculty of USC in 1963 and was awarded full tenure two years later. Golomb pioneered the identification of the characteristics and merits of maximum length shift register sequences, also known as pseudorandom or pseudonoise sequences, which have extensive military, industrial and consumer applications. Today, millions of cordless and cellular phones employ pseudorandom direct-sequence spread spectrum implemented with shift register sequences. His efforts made USC a center for communications research. Golomb was the inventor of Golomb coding, a form of entropy encoding. Golomb rulers, used in astronomy and in data encryption, are also named for him, as is one of the main generation techniques of Costas arrays, the Lempel-Golomb generation method. He is a regular columnist, writing Golomb's Puzzle Column in the IEEE Information Society Newsletter. He was also a frequent contributor to ''Scientific Americans ''Mathematical Games'' column. Among his contributions to recreational mathematics are ''Rep-tiles''. He also contributes a puzzle to each issue of the ''Johns Hopkins Magazine,'' a monthly publication of his undergraduate alma mater, for a column called "Golomb's Gambits", and is a frequent contributor to ''Word Ways: The Journal of Recreational Linguistics''.〔http://digitalcommons.butler.edu/do/search/?q=golomb&start=0&context=684035〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Solomon W.
