Since I don’t have enough on my plate already, I have decided that I should try and learn a bit of category theory. There seem to be plenty of resources online, so maybe I manage to dig through some of them and learn something interesting.
Seems that recently I have been tinkering a lot with various kinds of numbers and sequences of numbers. This entry doesn’t differ from previous ones in that respect, as I’m going to show two straightforward ways of computing prime numbers.
I recently read a blog posting that among other things touched patterns in mathematics, how they seem to be obvious to some people while others strugle and if there would be something that schools should do differently in teaching mathematics. Those of you who know me, can guess that this is close to my heart (after all, I keep bringing up Lockhart’s Lament often in day to day discussions). So I dug out my trusty Hy REPL and started playing with sequences just to see what one could do with them.
