Math and Magic Equal Sum Fun

Persi DiaconisThe Minnesota Daily profiles Persi Diaconis' use of magic to teach math; or math to learn magic tricks.  

Either way, it involves magic so it makes our pages.  (It is also featured on our sister site, Inside Mathematics – which received its 100th hit last week after only two years in existence). 

Here was the Stanford Professor's first effect:

Persi Diaconis tossed a sealed deck of cards into an overflowing audience Wednesday night in a Willey Hall auditorium. He asked the man who caught it to cut the deck and pass it along the row while each person took a card.        
    
Then Diaconis told each person which card they had picked — and he was right.

Dr. Diaconis did not use a Svengali or Peek deck.  No, he used something far more exotic – math. 

But does he know how to do the seven piles of cards spread all over the table trick?  

Nope.

“When somebody says they’re going to do a math-magic trick, it sounds as if they’re going to deal cards in piles, and you’ll all fall asleep,” Diaconis said. “I try to develop tricks that are good tricks that don’t look like math, but that have real math hidden in them.”

The profs at the University of Minnesota know Dr. Diaconis for his research in statistics and probability as well as his magic skills.

"He has brought a lot of insight into the way randomness works," one Minnesota professor noted.  "People think it's easy, but it's not."

Quinlan's Inside Magic has long been on record as standing for the proposition that randomness is not easy.

Blaine Continues to Not Do Magic

David Practices Holding BreathThe press continues for David Blaine and his career of "not doing magic."  The web site Wiz Bag lead their coverage of the Blaine press release for the upcoming Drowned Alive ABC special with the headline:

"Continuing to Not Do Magic David Blaine is Back"

The remainder of the article covers essentially the same waterfront cited here and in other magic and non-magic journals:  

 "David Blaine intends to sleep with the fishes — but only for a week, and in full public view.The 33-year-old magician will perform his latest stunt by living underwater for seven days and nights in a 'human aquarium' in front of New York's Lincoln Center.

He will conclude by attempting to hold his breath underwater longer than the record of 8 minutes, 58 seconds.

The finale of his latest stunt will air live in a two-hour ABC special on May 8 (8 p.m. EDT).

Blaine's previous feats of endurance include balancing on a small platform for 35 hours and surviving inside a massive block of ice for 61 hours, both of which were performed in New York. In 2003, he fasted for 44 days in a suspended acrylic box over the Thames River in London.

The 'human aquarium' in which Blaine will float is a specially built 8-foot acrylic sphere. He will receive liquid nutrition through a tube and the water will be kept at a balanced temperature to help keep his core temperature close to 98.6 degrees F.

Passers-by will be able to touch the aquarium, take pictures with Blaine and communicate with him. He will enter the sphere on May 1.
