As we construct more complex organic molecules, it can start to feel like decrypting a complex code. Organic synthesis takes simple starting materials, and turns them into complex structures, and reverse engineering can help us figure...

Today we’re going to take a step back from programming and discuss the person who formulated many of the theoretical concepts that underlie modern computation - the father of computer science himself: Alan Turing. Now normally we try to...

There are lots of different ways to encrypt a message, from early, simple ciphers to the famous Enigma machine. But it’s tough to make a code truly unbreakable.

Computers and computing have changed a lot over the History of Science but ESPECIALLY over the last 100 years. In this episode of Crash Course History of Science, we have a look at that history around World War Two and how that conflict...

The Enigma machine could pair up letters in 150 million million ways. How did the machine work to give so many different permutations – and how was the code eventually cracked? Maths - Number A Twig Math Film. Reinforce and extend the...

Why Turing devoted his life to the quest of what we now know as artificial intelligence, and invented the first algorithms that now form the basis of all programmed computers. Maths - History Of Maths A Twig Math Film. Reinforce and...

Elizebeth Friedman revolutionized American cryptology and played a crucial role in bringing down mobsters and spy rings in the 20th century.

In this episode of Travel Thru History we’re wading from the Bayou to the Boulevard in the deep south of North America to a city that knows how to have a good time. It hosts one of the biggest festivals in the country and is well-known...
