	Lifelong debunker takes on arbiter of neutral choices
		Diaconis set out to test what he thought was obvious -- that coin tosses, the currency of fair choices, couldn't be biased.
		Diaconis first approached statistics Associate Professor Susan Holmes, who is also his wife, and asked if he could try her computer's camera.
		Though Diaconis had made a key conceptual leap by connecting falling cats and flipped coins, he still hadn't found a camera that could adequately capture the complex motion of a split-second coin toss.

	Discussion Supper with Magician-turned-mathematician Persi Diaconis
		Persi Diaconis began his professional life as a magician at age 16-only enrolling in college eight years later when he took a probability class to improve his understanding of certain magic tricks.
		Professor Diaconis is the world's foremost authority on the speed of convergence of Markov chains to equilibrium, which he translates into everyday life by showing that a deck of cards can be properly shuffled, or randomized, in seven shuffles, but not six.
		Professor Diaconis, the Mary Sunseri Professor of Mathematics and Statistics at Stanford, will be visiting IU as a Patten Lecturer.

	Persi Diaconis - magician turned mathematician « Perfectly Reasonable Deviations
		Diaconis set out to test what he thought was obvious — that coin tosses, the currency of fair choices, couldn’t be biased.
		For example, people had long supposed that a few shuffles were sufficient to randomize a deck of cards — until 1992, when Diaconis and Columbia University’s David Bayer proved that thorough mixing requires seven shuffles.
		To make his point, Diaconis commissioned a team of Harvard technicians to build a mechanical coin tosser — a 3-pound, 15-inch-wide contraption that, when bolted to a table, launches a coin into the air such that it lands the same way every single time.

	Statistical science department holds conference
		Persi Diaconis, Cornell professor of mathematics and of operations research and industrial engineering, and a member of the university's new department, provided the keynote address on "The Search for Randomness," Thursday night.
		Diaconis, who studied music at Juilliard and toured at one time with magician Dai Vernon, explained that in his search for randomness, he's found that the report that coin flips come up heads half the time and tails the other half has been greatly exaggerated.
		Using overhead projections, Diaconis went on to discuss how roulette wheels, dart boards and certain card tricks may seem random, but when statistics and physics are applied to understand what lies behind them, the curtain of randomness is lifted.

		It's a fascinating result.'' Dr. Persi Diaconis, a mathematician and statistician at Harvard University who is the other author of the discovery, said the methods used are already helping mathematicians analyze problems in abstract mathematics that have nothing to do with shuffling or with any known real-world phenomena.

	Concerning the Statistical Test
		Diaconis in his capacity as referee received a copy of the article both before and after the experiment was conducted and confirmed it.
		Diaconis' objection was that to use these measures to direct evaluation of the significance is incorrect.
		The only place Diaconis discusses a possible definition of t, (that is a numeric value representative of a set of c(w,w') values belonging to one personality) is in his letter of 3 August 88, and it is for the purposes of a preliminary investigation he conducted himself.

		Diaconis calls this a “gem-like example of what we know that isn't so”, but also concludes that “if you flipped a coin vigorously, it was going to be fair.” The mathematics of Persi Diaconis is characterized by an ingenious use of several brands of mathematics, as well as physics.
		Of course, Diaconis is well-known for his use of discrete mathematical techniques in several of his key papers.
		Diaconis also made other important contributions in, for example, Bayesian statistics (primarily with David Freedman), on the statistics of (contingency) tables and on random matrices and permutations.

		Diaconis has done outstanding work in probability, statistics, and combinatorics.
		His pioneering applications of non-commutative Fourier analysis and techniques from algebraic structures have contributed greatly to our understanding of random walks on finite structure models for group valued data, and simulations of probabilities on combinatorial structures.
		This involves working on foundational issues like the nature of randomness as well as understanding the costs and benefits of mixing a-priori information with data in high-dimensional problems.
