For those of us who’ve gotten a little rusty in math and science since school (or for me, more than a little rusty in math), which web sites are good for a refresher course in physics and math? Not necessarily a site that’s going to help me finish up that PH.d dissertation, but just a reminder about the mid-level stuff that’s dropped out of memory over the years.

Shared pain is lessened; shared joy is increased.

For Physics reference I like here:

[Treasure Troves](http://www.treasure-troves.com/physics/physics0.html)

It’s kinda like an on line dictionary, searchable, with all those formulea that have been pushed out of the brain by simpsons episodes.

Ack, I forgot the same guy has a mathematics database too.

It’s here:

This here’s a good chronology of physics, from the ancients ot present day, complete with hyperlinks to all relevant topics:
