Day 84

Somewhat confusingly, today turned out to be Thursday, what with chimichangas and everything. I never could get the hang of Thursdays.

The book on complex analysis I'm reading at the moment recommends a program for visualizing complex transformations. However, it's not one I'm going to buy—firstly, there isn't a Mac version, but more importantly the price is $130.

To be fair, there is a free demo version, but even so I'm stunned at the price of the full version. I mean, who's going to cough up that much for a mathematics visualization aid? I suppose there will be the odd lecturer who uses the software in a class and can charge the cost to their department, but I can't imagine there'll be anyone else. Maybe I'm wrong and they get a steady income from it, in which case maybe I should stop giving this sort of stuff away for free :-).
