One of my favorite scenes from Stephen Spielberg's movie Lincoln captures how Euclid's Books of Logic and Geometry shaped thousands of minds including Abraham Lincoln. "Things which are equal to the same thing are equal to each other." This SELF-EVIDENT truth shaped President Lincoln which in turn shaped the future of our country and millions of lives around the world.
I believe my students saw mathematics in a new light today connecting history, logic, decision making, war and peace.
Every student should see the entire film of Lincoln.
