Sometimes you need a quick solution for notetaking. And when mathematical notation is involved, sometimes even LaTeX can be too slow. Enter two resources: on one hand, TiddlyWiki, "a reusable non-linear personal web notebook" and, on the other, ASCIIMathML. Add a few more components, such as the ability to create some basic SVG drawings with ease and you obtain ASciencePad, "a TiddlyWiki suitable for scientific notes".

Not the most sophisticated tool ever, agreed, but a very nice and useful addition to the flash drive in your pocket, and a nice suggestion for students.
