[Rhodes22-list] Rogue waves

[Chris Geankoplis]

Unlike Slim I am technically a Rogue.  I live in the Rogue Valley, I go
white water rafting on the Rogue River and my behavior well enough said.
But if you really want to know about Rogue Waves See:
DISCOVER magazine, Vol. 25 no. 7  July 2004 issue page 48.  "The Phyusics of
Pure Hell at Sea".  It has lots of info data and for Roger, math!  Oh yes,
lots of picture for the rest of us!
