Google Doodle -- Leonhard Euler

This has been cross-posted to my micro-blog, Tumbld Thoughts.

Today's Google Doodle (still shot of animation shown here) is in celebration of Leonhard Euler's posthumous 309th birthday. He may be dead in the flesh, but his ideas live on [1]. He had an incredible output of coherent (and long-lived) ideas, some of which are used in technologies as diverse as aircraft design, global positioning systems, the design of virtual (computer) interfaces, and holographic design [2].


[1] For those who are unfamiliar with his work, he's postage stamp worthy (see above image). This used to be a big deal. Perhaps in Europe it still is.

[2] Mathematical and physical tools such as Euler angles and Euler's disks (here is video demo of Euler angles in the context of a phenomenon called gimbal lock and Euler disks in the context of holographs).
