This is a great list but I want to add two more informative websites to it:

• sixtysymbols (physics and astronomy)
• numberphile (“videos about numbers and stuff”)

Reblogged for the cause.

Also:  Learnzillion.com

these sites saved me so much money during grad school

• openculture
• wikibooks
• google books
• upenn online library
• stanford database of free online articles
• scribd (this one you have to upload content to get content but its worth it)

also, all of carl sagan’s cosmos and a lot of the nova series are free on hulu fyi

there are so many others but these are my favorites

brilliant
