"There is no smallest among the small and no largest among the large; but always something still smaller and something still larger." -- (Anaxagoras, ca. 450 B.C.)

Math History Tidbit:

Mary Somerville (1780-1872): Scottish-born Somerville lived during a time when women were not supposed to be educated in mathematics and science. Despite opposition from her own parents, she created her own personal library with books on algebra, geometry, logarithms, calculus, physics, astronomy, and probability theory. She eventually published many outstanding papers and articles...and went on to publish four books, including The Mechanism of the Heavens , which resolved many mathematical problems relating to astronomy. In 1835, Somerville and Caroline Herschel were named as the first honorary female members of the Royal Astronomical Society.
