Veritasium: The strange math that predicts anything

After one of my first presentations at the students' conference OpenReadings, I received a comment along the lines of "it's just some fancy randomness". Well, yes, but... Over the years, I have seen lots of otherwise good students who struggle with even the most basic statistical concepts. So, being "fancy" makes it reasonably hard. Furthermore, random processes underlie many important everyday systems.

This Veritasium video tells a fascinating story about how a petty feud between two Russian mathematicians led to the development of Markov chain formalism.
