A New World Record for the Irrationality Measure of Pi

Doron Zeilberger, Rutgers University

Location:  Hill 705
Date & time: Thursday, 27 February 2020 at 5:00PM - 6:00PM

Abstract: Not all irrational numbers are born equal. The irrationality measure of a number tells you how `irrational' it is. It is a competitive sport to find better and better bounds for famous constants like Pi. V. Kh. Salikhov's 2008 upper bound of 7.606308 was the world record until Dec. 2019, when Doron Zeilberger and Wadim Zudilin proved a new world record of 7.10320533.
