I would advise against simply pointing people to the Quantum Physics sequence. The first, most quantum-ey part is largely good. The other stuff is much less so.

AAanyhow, I like the list. It's a good thing to point people to if they just want to explore.

EDIT: I shall start a Notable Standalone Posts (or something like that) sequence (Part 1) on the wiki soonish - seeing all these has made me realize that it's tough to not lose good solo posts.
