Theorems about triangles and circles
In Euclidean plane geometry, Lester's theorem states that in any scalene triangle, the two Fermat points, the nine-point center, and the circumcenter lie on the same circle.The result is named after June Lester, who published it in 1997, and the circle through these points was called the Lester circle by Clark Kimberling.Lester proved the result by using the properties of complex numbers; subsequent authors have given elementary proofs, proofs using vector arithmetic, and computerized proofs.

Calculus: The Fundamental Theorem of Calculus
This is the second of two videos discussing Section 5.3 from Briggs/Cochran Calculus. In this section, I discuss both parts of the Fundamental Theorem of Calculus. I briefly discuss why the theorem is true, and work through several examples applying the theorem.

Many problems in probability and statistics can be modeled as follows: before you are two urns containing some colored balls. You know the contents of urn A, and the (different) contents of urn B, but you don't know which urn is A and which is B. You get two chances to draw a ball at rando
