Great Speeches

University of Illinois

 

In his first major political speech since leaving office, former President Barack Obama took aim at the Trump administration and Republicans in Congress — blaming them for inciting division and stoking fears in the country.

Obama delivered the address at the University of Illinois Urbana-Champaign campus, where he also accepted the Paul H. Douglas Award for Ethics in Government from the Institute of Government and Public Affairs.

What made Abraham Lincoln's speeches great? Geometry, according to the authors of a newly re-issued book about the 16th President.

It isn't so much the mathematical properties of space that influenced Lincoln's speeches as the principles of demonstration outlined by the ancient Greek mathematician Euclid.
