An Overview of Cryptography As an aside, the AES selection process managed by NIST was very public. A similar project, the New European Schemes for Signatures, Integrity and Encryption (NESSIE), was designed as an independent project meant to augment the work of NIST by putting out an open call for new cryptographic primitives. NESSIE ran from about 2000-2003. While several new algorithms were found during the NESSIE process, no new stream cipher survived cryptanalysis. Philosophy .. My purpose therefore is, to try if I can discover what those principles are, which have introduced all that doubtfulness and uncertainty, those absurdities and contradictions into the several sects of philosophy; insomuch that the wisest men have thought our ignorance incurable, conceiving it to arise from the natural dullness and limitation of our faculties. (George Berkeley) Ignorance more frequently begets confidence than does knowledge: it is those who know little, not those who know much, who so positively assert that this or that problem will never be solved by science. (Charles Darwin, Introduction to The Descent of Man, 1871) Hi Everyone (December, 2009)

NUMB3RS Episode 616: Cause and Effect LARRY (cont'd) At the request of the bride and groom, I will keep my remarks short and non-technical. As you know, there are four fundamental forces in physics: electromagnetism, strong nuclear interaction, weak nuclear interaction, and gravity. The liquid-drop model in nuclear physics was originally proposed by George Gamow and developed by Hans Bethe and Carl von Weizsäcker in the 1930s. It treats the nucleus as an incompressible fluid of protons and neutrons bound together by the strong nuclear force. It treats the nucleus as an incompressible fluid of protons and neutrons bound together by the strong nuclear force. LARRY Social network models interpret the structure of human relationships: social, economic, political.

- StumbleUpon Perpetual Futility A short history of the search for perpetual motion. by Donald E. Simanek Popular histories too often present perpetual motion machines as "freaks and curiosities" of engineering without telling us just how they were understood at the time. They also fail to inform us that even in the earliest history of science and engineering, many persons were able to see the futility and folly of attempts to achieve perpetual motion. Sometimes a particular device comes to us with a label, such as "Bishop Wilkins' magnetic perpetual motion machine." Popular articles leave the impression that the inventor believed it was a perpetual motion machine.

The Metric System The Metric System By the eighteenth century, dozens of different units of measurement were commonly used throughout the world. Length, for example, could be measured in feet, inches, miles, spans, cubits, hands, furlongs, palms, rods, chains, leagues, and more. The lack of common standards led to a lot of confusion and significant inefficiencies in trade between countries. At the end of the century, the French government sought to alleviate this problem by devising a system of measurement that could be used throughout the world. Online texts Professor Jim Herod and I have written Multivariable Calculus ,a book which we and a few others have used here at Georgia Tech for two years. We have also proposed that this be the first calculus course in the curriculum here, but that is another story.... Although it is still in print, Calculus,by Gilbert Strang is made available through MIT's OpenCourseWare electronic publishing initiative. Here is one that has also been used here at Georgia Tech. Linear Methods of Applied Mathematics, by Evans Harrell and James Herod.

A new formula for avoiding supermarket queues Supermarket queues are dreaded by many. In the TV series ‘Supernatural’, people standing in an endless queue are used as an example of what hell really looks like. (Photo: Colourbox) In researcher Kebin Zeng’s office hangs a big whiteboard filled with mathematical formulas and functions. Complicated as it looks, it’s all about solving everyday problems such as supermarket queues.

Life 2.0: The little book of Flow - revised Here is the 'Little book of Flow' in one long post. The premise of this essay is that those exquisite but all too rare moments when we experience 'flow', when we are truly creative, happy and intuitively know exactly what is needed, are simply those instances when we glimpse our original and true nature. It sets out to show how, instead of trying to fathom the conditions for flow, we can realise this 'true nature' and make 'flow' our normal way of being, wherever we are and in whatever we do.
