I Like to Learn

I like to self teach. like I said earlier, I have made clear meaning for my life and value science as a body of collective knowledge and scientific thinking. I think learning about the physical universe is the only thing that puts meaning in my life. I thought I would post some of the resources I use to teach myself about science and other things that interest me...
This is already an overwhelmingly enormous amount of information despite not being a lengthy list, but does anyone else know any other good free educational sites? I'm looking for any free resources pertaining to science, languages or programming. I'll be adding to this list over time.
