Awesome graphic novel about the quest to find the foundations of mathematics. The main character is Bertrand Russell. Yeah, epic, I know. September 23 it hits the USA!
Open science. Everything here is accessible for free. Wee!
Ask it a question, and it brings you an answer. Kinda like Ask Jeeves, if Jeeves didn't just give you links and make you find out for yourself.
Sean Carroll gives a good introduction to cosmology.
Comic about academia, grad school. Funny!
Of course, if you follow me on SU, you've already seen this.
