A friend just showed this to me and I thought it was neat. There's always been a history of physicists wagering on theoretical or experimental results, but it looks like it has spread to the mainstream. You can bet on whether the Higgs boson will be discovered before the end of the year! http://www.intrade.com/jsp/intrade/common/c_cd.jsp?conDetailID=622296 [Broken] Isn't the LHC shut down, and Fermilab too short on statistics to even have a chance for a five sigma discovery? 20% chance seems very very optimistic Anyway, I was curious if people knew of other historic examples of physics wagers. Of course there are the fairly public wagers Hawking had. For particle physics the only one I heard of was (I think) Fermi wagering whether parity would be conserved or not (I don't remember which side he was on, or who was involved). Does anyone know the details or remember any other interesting examples?
