(... Long ago I watched a programme ( I thought it was in the Twilight Zone series ) about a rich man and a poor man. Some catastrophy happened and in their neighbourhood so they had to leave. The rich man took gold with him, as much as he could carry. Gold keeps its value and buys everything at all times. The poor man carried water as it was the first thing he might need. - The walk out of town took longer than expected and took them right into the desert. The rich got thirsty and decided to buy some water from his neighbor who still had enough for days, perhaps weeks. But he didn't sell. - Gold turned out to be worthless. ...) - I recalled this while I found another very interesting series of video lectures on discrete mathematics. Last year or so, complete lecture series on video were scarce on the internet. There were the MIT lectures, nothing more. Now ever more turn up. That's great but it's impossible to watch them all.
The one I found today is special though. It is a lecture series by Steven Skienna about Concrete Mathematics, a famous book by Ron Graham, Don Knuth and Oren Patashnik. A difficult book with many challenging problems. Worth reading over and over. A classic. The first lecture is about the Josephus problem. I might watch a few lectures, why not? It is cetainly related to MT365.
