Over the centuries many experime nts have been developed in order to approximate this quotient. In this tal k\, we discuss one such experiment. With only two billiard balls and a wal l\, and the assumption that momentum and kinetic energy are conserved\, we prove that one can generate the digits of Pi by counting the number of co llisions between these three objects along a straight line. To obtain more digits of accuracy we simply alter the weight of the second ball. Althoug h this isn't the most practical way to compute Pi\, it is certainly one of the most surprising.\n\n \n DTSTART:20170324T170000Z DTEND:20170324T170000Z LOCATION:1025 (10th Floor) - Graduate Lounge\, Burnside Hall\, CA\, QC\, Mo ntreal\, H3A 0B9\, 805 rue Sherbrooke Ouest SUMMARY:Math and Stats Graduate Student Seminar URL:/mathstat/channels/event/math-and-stats-graduate-s tudent-seminar-267244 END:VEVENT END:VCALENDAR
