Attending: Bill N, Robert S, Bob S, Deb S, Henri B, Diane B, Tom B.

Topic: How to Go Wireless in Your Home

Robert S, visiting from Texas, shared some spectacular images taken from the space shuttle by astronauts of the International Space Station orbiting the earth. Robert, a 1994 R.I.T. graduate majoring in scientific imaging, currently instructs astronauts on picture-taking for NASA.

He also showed us some of his own experiments (below) in panoramic photography, using a free application called Hugin - Panarama photo stitcher - Download (23.5mb) This software blends still pictures into a smooth mosaic. A QuickTime VR movie can be made from the mosaic by using GoCubic (PC only) - click under 'About GoCubic' to download. Mac users might try MakeCubic .

Other stuff

Pronounced 'cool' - cuil is the latest internet search engine. Very, very fast!
[Update 9/2010: guess it wasn't that 'cool' - it's gone belly up]

Did you know that the name of this famous search engine is derived from the word googol which is said to have been coined in the1940's by the 9-year old nephew of mathematician E. Kastner, when asked by Kastner to decribe a big number? The actual number is 1 followed by 100 zeroes.
