In Spring 2020, I co-taught a London Maths Outreach course entitled "Mathematical Aspects of Computer Science" with Kristina Kubiliūtė. The course was basically an introduction to circuits and specifically logic gates with an eye towards computation.
Due to the COVID-19 pandemic, the course was released online weekly in a series of YouTube videos on the London Maths Outreach channel. Here is a link to the course: a sample video is included below.
