Music And Computers, 4.6 Waveshaping Back in the 19th century, pafnuty chebyshev discovered a set of polynomialsknown as, you guessed it, the chebyshev Polynomials. http://eamusic.dartmouth.edu/~book/MATCpages/chap.4/4.6.waveshp.html
Extractions: Waveshaping Waveshaping is a popular synthesis and transformation technique that turns simple sounds into complex sounds. You can take a pure tone, like a sinewave, and transform it into a harmonically rich sound by changing its shape. A guitar fuzz box is an example of a waveshaper. The unamplified electric guitar sound is fairly close to a sine wave. But the fuzz box amplifies it and gives it sharp corners. We have seen in the earlier chapters that a signal with sharp corners has lots of high harmonics. Sounds that have passed through a waveshaper generally have more a lot more energy in their higher frequency harmonics, which gives them a "richer" sound. A waveshaper can be described as a function that takes the original signal x as input, and produces a new output signal y . This function is called the "transfer function". y = f(x) This is simple, right? In fact, it's much simpler than any other function we've seen so far. That's because waveshaping, in its most general form, is just any old function. But there's a lot more to it than that. In order to change the shape of the function, and not just make it bigger or smaller, the function must be non-linear which means it has exponents greater than one, or transcendental functions (like sines, cosines, exponentials, logarithms, etc.). You can use almost any function you want as a waveshaper. But the most useful ones output zero when the input is zero.
Extractions: Arab mathematician, lived when spread of ideas was very slow, wrote Hisab al-jabr wal-muqabala, concepts of the Middle East. The "al-jabr" gave us the word algebra." introduced the decimal system, rules for solving linear and quadratic equations, the word "algorithm" comes from his name.

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 American electrical engineer whose interest in radiotelephony led to the establishment of the first commercial radio station. Conrad worked for Westinghouse as assistant chief engineer at its East Pittsburgh Works and acquired over 200 patents in his lifetime. As an amateur , having built a transmitting station on the second floor of the garage behind his home in Wilkinsburg, Pa., when he substituted a phonograph for his microphone, he discovered a large audience of listeners who had built their own crystal radio sets and who, upon hearing the music, wrote or phoned requests for more music and news. When he became swamped with these requests, he decided to broadcast regular, scheduled
Extractions: Choose language ... History The Academy in the XIXth and early ÕÕth century. Development of University Science. Formation of Scientific Schools In the 19th and early 20th century the scope of research areas presented in the Academy was noticeably extended. Humanities were developing alongside natural sciences. In 1841, some of the members of the Russian Academy, which had been functioning for sixty years as an independent institution involved in the study of the Russian language and literary monuments, joined the "big" Academy of Sciences. A department of the Russian language and literature was added to the already existing departments: of physics and mathematics and of history and philology. Prominent Russian authors like Vasily Zhukovsky, Ivan Krylov and, later, Leo Tolstoy were members of the new department, that also accepted literary critics and linguists. The achievements of Russian physicists scored were no less impressive. As early as the beginning of the 19th century Vasily Petrov discovered the electric arc. Emily Lentz became widely known for his works in electromagnetism, Boris Yakobi proposed the method of galvanoplastics. An outstanding scientific achievement of Russian and world science was the invention of radio by Alexander Popov in 1895. In late 19th century, Evgraf Fedorov made a major contribution to crystallography and the establishment of crystallographic groups.

Extractions: January 23rd, 2002 To Blog, Or Not to Blog That 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! Im in two minds myself, I admit. Sure, I kind of like doing it; but yes, it does seem a bit like cheating. So what Im going to do is, give over about one column in ten, maybe one a month, to blogging. Ill always let you know, right there in the title, whether Im blogging or not, so if its 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 emails that go: Derb/Fred, Id love to say out loud the things that you say, but if I did, Id lose my job. We agreed that these are the saddest, and in a way the

Extractions: Bayes was a non-conformist minister in England. A version of what is now known as Bayes’ theorem was used in his paper "Essay towards solving a problem in the doctrine of chances," published in the Philosophical Transactions of the Royal Society of London in 1764. James Bernoulli was the first of the famous Bernoulli family of Swiss mathematicians. He wrote one of the early books devoted to probability, Ars Conjectandi , which was published after his death in 1713. Bernoulli formulated the version of the law of large numbers for independent trials, now called Bernoulli trials, and studied the binomial distribution. Buffon was the director of the Paris Jardin du Roi and was best known during his time for his thirty-six volume work on natural history. Buffon's famous coin and needle problems are considered to be among the first problems in geometric probability. Cardano, who lived in Italy, was a man of many interests: law, medicine, astrology, gambling, and mathematics. His book Liber de Ludo Aleae (The Book on Games of Chance), published after his death in 1663, contained perhaps the first mathematical analysis of gambling.
ABOUT PAUL ERDÖS The answer is yes, it is always true, but this was first proved only in 1850,by pafnuty Lvovitch chebyshev, the father of Russian mathematics. http://bookbuzz.com/MBIO_About_Erdos.htm
Extractions: but a separate article prepared by its author, Bruce Schechter) F OR OVER half a century, early in the morning or in the middle of the night, mathematicians in Budapest or Berkeley, Prague or Sydney have been summoned from their multi-dimensional dreams by a knock at the door. Their unexpected guest was a short, smiling man wearing thick glasses and an old suit. In one hand he held a small suitcase containing everything he owned, in the other a shopping bag stuffed with papers. It was Paul Erdös, one of the greatest mathematicians of the twentieth century, a man who lived in the space of Platonic Ideals and infinite beauty, who called no place on Earth home. Never one to waste time on formalities with work to be done, Erdös would announce to his host: "My brain is open!" For the next few days, brains open, Erdös and his host, with other mathematicians recruited as needed, would be off on a mathematical journey of problem, conjecture, theorem and proof. The goal of their journey was nothing less than Truth and Beauty. "If numbers aren't beautiful, I don't know what is," Erdös once remarked. While the pursuit of mathematical beauty was Erdös's only goal, his ideas inevitably have found practical applications. One of the small ironies of Erdös's life is that, although he never owned or used a computer, mathematics that he invented is the basis for modern computer science; although he never had a secret, his mathematics is used by those who invent secret codes.

Extractions: Johns Hopkins University Press, Baltimore, 1983 In order to be able to measure distances with respect to vectors and matrices we have defined normed spaces. Most of the spaces used in this course are Banach spaces Stefan Banach (1892-1945) . For the vector norms different choices are made. An important class of norms are the so-called Hölder norms Otto Ludwig Hölder (1859-1937) . For the special choice p=2 we get the Euclid norm Euclid ( 295 b.c.e.- ) . With respect to matrix norms we consider norms derived from vector norms. Furthermore we mention the Frobenius norm George Ferdinand Frobenius (1849-1917) Furthemore we use spaces where an inner product is defined. Most of these spaces are Hilbert spaces David Hilbert (1862-1943) . Using the Hölder inequality we show that the Euclid norm satisfies the Cauchy-Schwarz inequality Augustin-Louis Cauchy (1789-1857) and Karl Hermann Amandus Schwarz (1843-1921) We start our description of direct methods for solving linear systems with the Gauss elimination method Carl Friedrich Gauss (1777-1855) . Thereafter we discuss the Choleski method for symmetric positive definite matrices. Furthermore we show that much work and memory can be saved in the case of band matrices. An important example of a banded system is the discretization of the Poisson equation
