IMAGES OF MATHEMATICIANS ON POSTAGE STAMPS
Jeff Miller, Gulf High School, New Port Richey, FL
http://jeff560.tripod.com/
An alphabetical list of mathematicians whose images appear
on postage stamps: Abel, Archimedes, Cauchy, Descartes,
Euler, Galois, Gauss, Kovalevskaya, Laplace, Leibniz, Newton,
Pascal, Poincare, Ramanujan, and more. Countries, dates of
issuance, and links to enlarged images of the stamps are
provided.
In addition, Other Mathematics Stamps include Globe and
Sputnik orbits, the Pythagorean theorem, Maxwell's Law,
Napier and logarithms, Einstein's theory, and many more.
Jeff Miller is also the author of Earliest Uses of Various
Mathematical Symbols and Earliest Known Uses of Some of
the Words of Mathematics:

AXIOM OF CHOICE (AC) - Eric Schechter
http://www.math.vanderbilt.edu/~schectex/ccc/choice.html
"To choose one sock from each of infinitely many pairs of
socks requires the Axiom of Choice, but for shoes the
Axiom is not needed." - Bertrand Russell
An introduction to and some implications of perhaps the
last great controversy of mathematics, the Axiom of Choice,
now a basic assumption used in many areas of mathematics.
Eric Schechter, Departmental Webmaster and Associate
Professor of Mathematics at Vanderbilt University, includes
a collection of annotated links to related sites:
- Introductory/elementary
- Especially noteworthy books and/or researchers
- Slightly more advanced and specialized topics
- Formal logic and/or automatic theorem-proving
- Miscellaneous

CANCER AND MATHEMATICS - Dildine, Silver
An Internet Adventure into Cancer, Pattern
Recognition and Image Analysis, and Geometry
http://www.mste.uiuc.edu/dildine/cancer/cancer.html
Cancer is a group of diseases in which some body cells change
their nature, start to divide uncontrollably, and may revert
to an undifferentiated type. Through Java applets and
Geometer's Sketchpad files to download, this lesson explores
the ratio (perimeter squared to area) that designates a
cancerous cell.

Education (MSTE) at the University of Illinois at
Urbana-Champaign (UIUC).
