The Central Processing Unit (CPU): Crash Course Computer Science #7

Today we’re going to build the ticking heart of every computer - the Central Processing Unit or CPU. The CPU’s job is to execute the programs we know and love - you know like GTA V, Slack... and Power Point. To make our CPU we’ll bring in our ALU and RAM we made in the previous two episodes and then with the help of Carrie Anne’s wonderful dictation (slowly) step through some clock cycles. WARNING: this is probably the most complicated episode in this series, we watched this a few times over ourselves, but don't worry at about .03Hz we think you can keep up. 

How The Most Useless Branch of Math Could Save Your Life

There is an entire branch of math simply devoted to knots – and it has changed the world. We’ll rope you in.

Todays Thought

 Amateurs sit and wait for inspiration, the rest of us just get up and go to work. 

-Stephen King, novelist (b. 21 Sep 1947)

Electrons DO NOT Spin

Quantum mechanics has a lot of weird stuff - but there’s thing that everyone agrees that no one understands. I’m talking about quantum spin. Let’s find out how chasing this elusive little behavior of the electron led us to some of the deepest insights into the nature  of the quantum world.
