...prime number is one which is divisible only by itself and 1. Thus 7, 13, 17 and 23 are prime numbers. In Chicago, one Samuel I. Krieger covered 72 sheets of foolscap paper, wore six pencils to stubs. Last week he announced a 72-digit prime number, challenged the world to show him a bigger one. His number...

...boasting is well founded. Professor James David Weinland of New York University found that Calculator Finkelstein can add five single digit numbers in 1/1000th of a second, six single digits in 1/660th of a second. In one second he can scan a dozen two-digit numbers and call out the total. He can glance at a twelve-digit number, as 122,432,523,591, and repeat it 24 hours later. He attributes his speed and accuracy to "swift perception, long memory span, fluent associations, concentration, imagery." The number 9,836, for example, means to him 90 squared, plus 40 squared...
