The journey from a coffee machine to bitcoin

How the need for a reliable monetary system leads to the discovery of blockchain through a series of catastrophic failures I remember when we moved to our new offices. They were spacious, bright and squeaky clean, but they weren’t cozy. Going from point A to point B was always [..]

How to discover multiplication using set theory

We have seen in another post that set theory is a good candidate to most fundamental theory of the universe. One of the reasons for it is that the rest of mathematics can be derived from it. Let’s see, as an example and mainly for fun, how to multiply [..]
