User:Nikenuke
My user name refers to my service in the US Army: in Nike-Hercules air defense and in the Army Nuclear Power Program. For my background, go to Wikipedia and enter "user:rb88guy" in the search box. In brief: I'm a retired nuclear scientist; Master's from Georgia Tech; experience dating back to 1960's; peer-reviewed publications; have taught AP Physics. Strong background in applied statistics, applied math. Programming, in various languages.

Here are direct links to my contributions at Geogebra (which I have only been using for a couple of months); comments/suggestions are of course welcome. Some of these file names are a bit weird since I had to use a new name for each edit (...???...) If there is some app, or mod of these, that you would like to have me do, especially for teaching purposes, let me know.
