Regarding computing as a straightforward routine, some theoreticians still tend to underestimate its intellectual value and challenge, while practitioners often ignore its accuracy and overrate its validity. C. K. Chu, Columbia University, 1978

## Foundations of Turbulence

The mathematical formulation of the problem of homogeneous turbulence is this: Given an infinite body of uniform fluid in which motions conform to the equations and, and given that at some initial instant the velocity of the fluid is a random function of position described by certain probability laws which are independent of position, to …

## Proof that Any Number Equals Itself from the Hunting of the Snark

$$\frac{(x+7+10)(1000-8)}{992}-17$$

## Acoular

http://www.acoular.org/ My students and myself have had some good luck with the open source and free software package Acoular. We used it to try and visualize the acoustic source distribution within a tornado. It worked fairly well, but of course the technique is dependent on the quality of data used. This is generated by CFD …

## Andrei Nikolaevich Kolmogorov – A Digital Tribute

http://kolmogorov.com The great Academacian Andrei Nikolaevich Kolmogorov, who pioneered turbulence theory and started the Russian school, has fans overseas (big surprise!). I always wanted to create a website with a collection of his pictures, portraits, important articles, and anything else I could find online or off. Someone of course beat me to it! A recommended …

## Eugene B. Dynkin Collection of Mathematics

Cornell has published a series of Mathematical Biographies of a number of famous mathematicians. When I do history portions of my classes I have often referred here. It is worth a scroll for your favorites. Check out Krylov for instance. http://dynkincollection.library.cornell.edu/ http://dynkincollection.library.cornell.edu/browsebios
