When I was young, if I wanted to make a skirt, we went to the fabric store, looked through the pattern books, bought the pattern, fabric, and notions, pinned the tissue to the pattern, cut out all the little triangles... and so on. Eleanor, on the other hand, picked up some fabric from a trunk sale, looked up free skirt patterns on the web, printed off the directions and went to town. Now she's almost one skirt richer.
Why you should study the history of math In the mid 1300s a fad made its way around Italy. Mathematicians would challenge each other to “mathematical duels”. They would post problems for their opponents to solve, sometimes along with their solutions in coded poetry. The winners would get support and funding from rich patrons, the losers would descend into obscurity. One such contest, between Fiore and Tartaglia, involved a new method for solving the cubic. In order to win, Tartaglia worked day and night to find Fiore’s method---unfortunately, Fiore did not do the same and only knew his own method and no others. (*Recall that the formula for solutions to quadratic equations of the form use the quadratic formula, Giorlamo Cardano---physician, philosopher, astrologer and mathematician---convinced Tartaglia to share his method and promised never to reveal it. Then Cardano figured out a more general method, and wanted to share it, but was blocked by his promises. Fortunately (for Ca...
