AI Thread Summary
On July 14, 2025, a bridge player was dealt two hands where the highest card was a seven, an occurrence with odds of approximately one in 250 million. The discussion highlights the confusion surrounding the calculations, with participants providing varying estimates, including one of about 234 million. Despite the discrepancies, there is a consensus that the rarity of this event is astonishing. The conversation also references a Wikipedia article on "Go and Mathematics," which discusses similarly improbable scenarios. The rarity of such hands in bridge showcases the game's unpredictability and the fascinating nature of probability.

Pretty wild, I'll admit.
 
There's a "Go and Mathematics" article on Wikipedia which also "sports" some pretty wild numbers.

Note the blank on left of the turnstile symbol ##\vdash_S##, as far as I can tell it actually represents the empty set. So what does it mean ? I guess it actually means ##\phi## is a theorem of the formal system, i.e. there is a...
