The Euclidean Toolbox An online tool to help you with
compass and straightedge constructions. If you are in one of the University's
computer labs, it should have at least one of the following:
(The Geometer's) Sketchpad, Dr Geo. All very interesting and all with the
potential to be very helpful.
Wikipedia
A good source for interesting and often also true mathematical tidbits. Try
searching for biographies of the mathematicians listed below.
Euclid, Erastothenes, Pythagoras, Heron, Brahmagupta, Descartes, Newton,
Euler
Lots of mathematical info from
Wolfram Research ,
one of the world leaders in mathematical computer software,
based right here in Urbana-Champaign.
Euclid's Elements: The book(s) that helped start it all.
The MacTutor
History of Mathematics archive : Mathematicians' biographies and more!
The Most Pleasing
Rectangle Web Poll Poke around the rest of Jim Loy's webpage
for some more interesting stuff.
Demetri Martin (a stand-up comedian) corrects the
Rock, Paper, Scissors game (among other things).
The Geometric Meaning of the Geometric Mean Plenty of pictures
showing the geometric mean in action.
When would you use the Geometric Mean? Average rate of return on
investments, averages of things that fluctuate (the stock market for
example), center frequencies, averages of things that you are multiplying
by.
