I will then move on to the Axiom of Choice\, and demonstrate its 'weir dness' by using it to solve a few difficult riddles\, which seem impossibl e at first glance. All graduate students are invited. As with all talks in the graduate student seminar\, this talk will be accessible to all gradua te students in math and stats.\n \nWe will also be continuing to serve piz za.\ngraduate student seminar DTSTART:20160916T163000Z DTEND:20160916T173000Z LOCATION:Room 1205\, Burnside Hall\, CA\, QC\, Montreal\, H3A 0B9\, 805 rue Sherbrooke Ouest SUMMARY:James Rickards URL:/mathstat/channels/event/james-rickards-262747 END:VEVENT END:VCALENDAR
