A course aimed at people who have a strong sense that what Einstein did changed everything but do not know enough physics to understand what he did and why it was so important. The course presents just enough of Einstein’s physics to give students an independent sense of what he achieved and what he did not achieve.

This manifesto is dedicated to one of the most important numbers in mathematics, perhaps the most important: the circle constant relating the circumference of a circle to its linear dimension. For millennia, the circle has been considered the most perfect of shapes, and the circle constant captures the geometry of the circle in a single number. Of course, the traditional choice of circle constant is π—but, as mathematician Bob Palais notes in his delightful article “π Is Wrong!”,1 π is wrong. It’s time to set things right.
