Learning a bit more regarding photography in general. For instance, now I know the difference between Slow Synchro ("nighttime") and Fill ("forced") flash. It will be nice to be able to use them both when the situations arise.

A student of mine has lent me his "Towers of Hanoi" puzzle so that I can teach recursion for some students. The fact that recursion works so well for some cases seems to be surprising (like magic or wizardry, sometimes) for some students. They are not used to simple and elegant solutions to some problems.

Thank you very much, Victor!
