I want to teach myself computer science. I know that teaching myself is far from a university education on the subject, but I'd like to try. How can I teach myself? What are books/lectures/tools/websites/anything that I could use to do this? Covering everything from the programming languages themselves, to algorithms, software development, and the mathematics background necessary for this. [more inside]
Can anyone tell me where to research/find bulk viscoelastic rubber, or molded rubber that has viscoelastic properties? I'm looking for a material that when stretched, takes its sweet time in returning to its original size/shape. Turns out there are no rubber stores in my area to browse, thus no experts to turn to. Most info I've found online is scientific discussions about rubber properties.
What is a bricks-and-mortar store at which I could buy a set of model elements / bonds - the molecule model things that students use as they are learning organic chemistry? [more inside]

Teaching resources about racial concepts: their biological validity and various cultural expressions
I need teaching resources about race: the biology of human "races"; why "race" is not biological but social; how racial categories have shifted over time and place; and related questions on teaching about race? This is as a supplement to reading The Mismeasure of Man in a university "Critical Thinking" class. I need more science and verifiable cross-cultural examples to back up my "there are no biological races" claim. [more inside]

When I was a kid, I took a trip once. The whole time, a plush Hello Kitty doll was in the back of the car, bombarded by the sun. It changed color from pink to dark blue. Any explanation for this phenomenon? [more inside]
Why were there more black experts in 1980's "Free to Choose" than there typically are in today's TV?
When watching Milton Friedman's "Free to Choose" (PBS, 1980), I was (pleasantly) surprised at the high number of black experts (and women) who were guests in the show. Not the usually array of exclusively old, white guys one would have expected. [more inside]
I have a Masters in Library Science. I received it a year and a bit back. In that time, I have been applying for a job in the public library sector as a reference librarian. I am not getting anywhere though I am following professional protocol in regards to a sound cover letter and solid resume. I got a 3.6 GPA in the program which is decent but not perfect. Decent, though. I have recently been broadening my search to places outside of my home state of Indiana (and Indianapolis). If you have any recommendations for the best job site areas to review on a regular basis, I am interested. [more inside]

Anyone remember a great kids science book from the late 70's to the mid 80's? [more inside]
Help me properly remember this study or who wrote about it. It was about some animal that, in experiments, preferred the anticipation centers of their brain -- seeking circuits? -- stimulated over the pleasure centers. I read it in some poppish science book in the last few years and now I'm trying to more accurately recall it so I can use it in a talk, if I'm rembering it correctly. [more inside]

What are the best history of science books for the intelligent layperson? Some examples along these lines include Richard Rhodes' "The Making of the Atomic Bomb", David Bodanis' "E=mc2" and Dava Sobel's "Longitude"; books which mix equally well the explanation of scientific concepts with historical/biographical storytelling, and are not intended for practitioners of the field. In addition to general suggestions, specific recommendations about the history of probability & statistics and the history of science in the ancient/medieval world would be appreciated. Thanks in advance!

I read somewhere that, in theory, two solids coming into repeated contact should at some point (assume we're dealing with infinity) pass through each other. Nearest I can come is molecular harmonic resonance, or this slightly dubious writeup. Is this a observed phenomenon? Or is there a formal theory for this?
