I need advice on how to do a DIY portable hard drive. My grandparents just gave me my old old computer back (they broke the mouse, making it useless for solitaire and hence useless to them), and feeling adventurous, I ripped it apart. Now I'd like to actually use some of the stuff I pulled out. The ...
Assuming time travel is possible, it seems obvious to me that the classic time-travel paradoxes are all impossible. However, I absolutely hate the "universe protects itself" idea fro the movie The Time Machine, and the split timeline hypothesis or anything involving quantum mechanics seems...

With respect to the the parabolic reflective troughs, I've got an idea for how to make a relatively simple tracking system that can bypass any need for outside information like what time it is, or where the sun should be at that time on that particular day. Make a short, half-cylinder trough, and co...

I was really hoping to see Feynman's copy of Encyclopedia Britannica on this one. And "turtles all the way down," that'd be cool, especially in light of my wished for "Plenty of Room at the Bottom" reference. (Cause the turtles aren't supposed to be tiny, but they would make sens...

Since you place no restrictions on the robots except that they can only sense each other by touch, I am going to assume that they are capable of being Von Neumann machines. If a Von Neumann machine can build a copy of itself, it follow that it could also enlarge itself. So the instructions are: Incr...
Coheed & Cambria. They're a bit of an acquired taste, but once you get used to Claudio Sanchez's voice (think Geddy Lee but a bit higher at times) you'll freaking love them. Here are a few of their best: Welcome Home the music video is censored and shortened, here is the full version set to scen...
