David Butler

I’ve recently retired after a 40 year career in computer software development, where I helped build operating systems, parallel operating systems, and massively parallel database systems that represent a foundation for today’s social media and the internet. It was a very satisfying career.

My education was math and physics culminating in a masters degree from Oxford University studying the mathematical foundations of Quantum Mechanics out of the Math Institute attached to St. Catherine’s College. So I’ve always been very interested in science, physics, astronomy, cosmology.

I now produce free educational video books on YouTube. My first publication was "How far away is it". It covers how we know how far away things are. My second was "How small is it" on quantum mechanics. It covers how we know what we know down to the Higgs Boson. My third and most recent is "How fast is it" on the speed of light, special relativity and general relativity with a chapter on gravitational waves in development.
