Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

The concept of square roots dates back thousands of years, and despite the technological advances that offer quick calculations, it’s still essential to understand how to calculate a square root ...

A cube root is the number that, when multiplied by itself three times, equals a given number. In other words, it’s the inverse operation of cubing a number. Learning how to calculate cube roots can be ...

A new DNA computer calculates square roots of perfect squares up to 900. Like quantum computers, DNA computers are an exciting frontier of post-silicon computing. Where previous examples were up to 4 ...

A computer made from strands of DNA in a test tube can calculate the square root of numbers up to 900. Chunlei Guo at the University of Rochester in New York state and colleagues developed a computer ...

Sorry if this is a bit pointless/elementary, but I've always been interested in how interactive theorem provers approach this problem and how long the proofs end up being. I'd love to do a proof ...
