Doron Zeilberger (דורון ציילברגר, born July 2, 1950 in Israel) is an Israeli mathematician, known for his work in combinatorics. July 2 is the 183rd day of the year (184th in leap years) in the Gregorian Calendar, with 182 days remaining. ... Events January January 5 - US Senator Estes Kefauver introduces a resolution calling for examination of organized crime in the USA January 6 - The United Kingdom recognizes the Peoples Republic of China. ... Combinatorics is a branch of mathematics that studies finite collections of objects that satisfy specified criteria, and is in particular concerned with counting the objects in those collections (enumerative combinatorics) and with deciding whether certain optimal objects exist (extremal combinatorics). ...

He is a Board of Governors Professor at Rutgers University. He received his doctorate from the Weizmann Institute of Science in 1976, under the direction of Harry Dym. Rutgers University Rutgers, The State University of New Jersey, is located in New Brunswick, Piscataway, Camden and Newark, New Jersey. ... The Weizmann Institute of Science (מכון ויצמן למדע) is an institute of higher learning and research in Rehovot, Israel. ...

Zeilberger has made numerous important contributions to combinatorics, hypergeometric summation, and q-series. Zeilberger gave the first proof of the Alternating sign matrix conjecture; noteworthy not only for its mathematical content, but also for the fact that Zeilberger recruited nearly a hundred volunteer checkers to "pre-referee" the paper. Together with Herbert Wilf, Zeilberger won the American Mathematical Society's Leroy P. Steele Prize for Seminal Contributions to Research in 1998 for their development of WZ Theory, which has revolutionized the field of hypergeometric summation. In mathematics, a q-series is defined as usually considered first as a formal power series; it is also an analytic function of q, in the unit disc. ... The American Mathematical Society (AMS) is dedicated to the interests of mathematical research and education, which it does with various publications and conferences as well as annual monetary awards to mathematicians. ... The Leroy P. Steele Prizes are awarded every year by the American Mathematical Society, for distinguished research work and writing in the field of mathematics. ...

Zeilberger is also known for his opinions  (http://www.math.rutgers.edu/~zeilberg/OPINIONS.html), some of which are:

• "People who believe that applied math is bad math are bad mathematicians" (http://www.math.rutgers.edu/~zeilberg/Opinion2.html)
• "Guess what? Programming is even more fun than proving, and, more importantly it gives as much, if not more, insight and understanding" (http://www.math.rutgers.edu/~zeilberg/Opinion37.html)
• "Frank Quinn's rigor is not as rigorous as he thinks" (http://www.math.rutgers.edu/~zeilberg/Opinion53.html)
• "Still like that old-time blackboard talk" (http://www.math.rutgers.edu/~zeilberg/Opinion60.html)
