While attending a physics symposium in Las Vegas one year, Albert Einstein, to the astonishment of many of his sober-minded colleagues, spent a fair amount of time at the craps and roulette tables.

"Einstein is gambling as if there were no tomorrow," an eminent physicist remarked one day. "What troubles me," another replied, "is that he may know something!"

["As far as the laws of mathematics refer to reality, they are not certain," Einstein once remarked, "and as far as they are certain, they do not refer to reality."]

[In April 2004, Ashley Revell sold everything he owned, went to Las Vegas, and bet his life savings ($135,000) on one spin of a roulette wheel. "Never again," he later remarked. "It was mad!" (He won.)]
