The Bernoullis: When Math is the Family Business

TL;DR

The Bernoullis, a family of mathematicians from the 17th and 18th centuries, made significant contributions to probability theory, calculus, fluid dynamics, and physics, leaving their names on principles and concepts still taught today.

Transcript

If you’ve ever taken a science or math class, you’re probably used to lots of things being named after the same people. There are hundreds of principles and theorems and equations named after superstars like Euler and Laplace and Gauss. So it might not seem all that weird to learn about Bernoulli’s brachistochrone solution, Bernoulli’s equation in ... Read More
