Extractions: January 23, 2002 8:55 a.m. hat is the question. My previous attempts at bloggery drew a highly polarized response. Some readers said: "Sheesh, anyone can do that . Give us a good old-fashioned rant, Derb." Others said: "I love this blogging stuff! Opinion in bite-size chunks — cool!" I'm in two minds myself, I admit. Sure, I kind of like doing it; but yes, it does seem a bit like cheating. So what I'm going to do is, give over about one column in ten, maybe one a month, to blogging. I'll always let you know, right there in the title, whether I'm blogging or not, so if it's not your thing you can skip it. Fair? I was just having an e-conversation with the incomparable, ineffable and infinitely wise Fred Reed . We discovered that we both get lots of e-mails that go: "Derb/Fred, I'd love to say out loud the things that you say, but if I did, I'd lose my job." We agreed that these are the saddest, and in a way the scariest , of all the e-mails we get. It's great that we web hacks have freedom of speech. Would be real nice if the rest of the country could have it, too.

Extractions: German automotive industrialist who took part, with Max Valier and Friedrich Wilhelm Sander, in experiments with rocket propulsion for automobiles and aircraft. On 11 Apr 1928, at Berlin, they tested the first manned rocket automobile. On 30 Sep 1929, von Opel piloted the Opel Sander Rak.1, a glider powered with 16 rockets of 50 pounds of thrust each, and made successful flight of 75 seconds, covering almost 2 miles near Frankfurt-am-Main, Germany, Von Opel as pilot. By sponsoring these early tests of rocket-powered transport, Opel popularized the idea of rocket propulsion in Germany. Frank Conrad

Extractions: Naceu o 16 de maio de 1821 en Okatovo (Rusia) e morreu o 8 de decembro de 1894 en San Petesburgo (Rusia). En 1847 Chebyshev tomou posesión dunha praza de profesor na Universidade de San Petesburgo. Durante gran parte do tempo dedicouse ó estudio dos números primos. En 1850 probou a conxetura de Bertrand de que para calquera n 3 hai alomenos un número primo entre n e 2n. Tamén estivo moi preto de proba-lo teorema dos números primos: , sendo p (n) o número de números primos menores ou iguais que n. Concretamente Chebyshev probou que se o límite existe entón vale 1. Ademais destes traballos Chebyshev realizou moi importantes contribucións á teoría da probabilidade e tamén no estudio das formas cadráticas, de funcións ortogonais, da teoría de integrais e do cálculo de volumes xeométricos.

Extractions: Over US$130,000 has been donated since the drive began on 19 August. Thank you for your generosity! (Redirected from Chebyshev form In mathematics the Chebyshev polynomials , named after Pafnuty Chebyshev ), are a sequence of orthogonal polynomials which are related to de Moivre's formula and which are easily defined recursively , like Fibonacci or Lucas numbers . One usually distinguishes between Chebyshev polynomials of the first kind which are denoted T n and Chebyshev polynomials of the second kind which are denoted U n . The letter T is used because of the alternative transliterations of the name Chebyshev as Tchebyshef or Tschebyscheff The Chebyshev polynomials T n or U n are polynomials of degree n and the sequence of Chebyshev polynomials of either kind composes a polynomial sequence Chebyshev polynomials are important in approximation theory because the roots of the Chebyshev polynomials of the first kind, which are also called

Extractions: Ivars Peterson's MathLand December 23, 1996 "Prime numbers have always fascinated mathematicians," Underwood Dudley of DePauw University in Indiana wrote in a 1978 textbook. "They appear among the integers seemingly at random, and yet not quite: There seems to be some order or pattern, just a little below the surface, just a little out of reach." A prime is a whole number (other than 1) that is divisible only by itself and 1. That simple definition leads to the following sequence of numbers: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, and so on. As the numbers of the sequence increase, the intervals between primes, on the average, get longer, though in a somewhat haphazard way. In other words, primes gradually become more scarce as numbers get larger, and one can imagine that, at some point, they might run out. More than 2,000 years ago, however, the Greek mathematician Euclid proved that the sequence of primes continues forever. Suppose there is a finite number of primes, he argued. That means there's also a largest prime. Multiply all the primes together, then add 1. The new number is certainly bigger than the largest prime. If the initial assumption is correct, the new number can't be a prime. Otherwise, it would be the largest. Hence, it must be a composite number and divisible by a smaller number. However, because of the way the number was constructed, all known primes, when divided into the new number, leave a remainder of 1. Therefore, the initial assumption can't be correct, and there can be no largest prime.

Extractions: by Robin Wilson If you are interested in the beauty of mathematics, you must go out and buy Robin Wilson's absolutely stunning book of mathematical stamps, a book which traces the history of mathematics through images on the postage of countries around the globe. Why mathematics on stamps, you may wonder? After all, there are illustrations of mathematical ideas as well as portraits of mathematicians in other media. If we limit ourselves to just that mathematics which has been pictured on stamps, we cannot give a full or balanced history of mathematics. And the United States has very rarely portrayed a mathematician or a mathematical idea on its own postage stamps. Naturally, many countries have also honored mathematicians from elsewhere, because their influence has been global. Nicolaus Copernicus, Johannes Kepler, Galileo Galilei, and Isaac Newton, among others, appear on stamps of many countries. Wilson has shown but a small sample of these, including some which make some effort to represent the ideas of these great men. Many countries in fact believe that mathematical ideas are worth presenting on stamps to teach their populations. For example, in 1971 Nicaragua issued a series of ten stamps depicting the "ten mathematical formulae that changed the face of the earth." Most of these formulas are, of course, physical formulas, such as Einstein's formula expressing the equivalence of mass and energy and Newton's law of gravitation. But these also include the Pythagorean theorem and the relationship of logarithms to exponentials. Several more sophisticated ideas have appeared explicitly on stamps, including the basic formulas for the quaternions on an Irish stamp, the factorization of an ideal as a product of prime ideals on a German stamp, and the statement of Fermat's Last Theorem on a Czech stamp.
