Coffeehouse - The Speed of Light

Well the problem with that is that Einstein showed that the speed of light IS impossible to exceed. His theory is that the speed of light is a constant. For instance what they may be showing in this experiment is that the particles has reached a speed of 190,000 miles per hour. This does not mean that those particle are traveling faster than the speed of light because the speed of light is added to your current speed so it is impossible according to Einsteins theory.

"...electron's mass increase at very high speeds because it is approaching the universe's speed limit, and the enormous amount of energy needed to attain such high speeds actually weigh on the electron to keep it from reaching the speed of light." from Albert Einstein and the Theory of Relativity.

Tech Off - Making your own Radar

Algorithum — Tue, 12 Jul 2011 21:46:56 GMT

I was wondering if Clint Ruktas would be interested in making a radar. I was reading a advanced Ham radio book and one of the chapters was on radio location. It was really interesting and I think it would make a good project for coding for fun. Now I was thinking about an actual antenna and everything and hacking a digital ham radio, but that would be really complicated. So I though about just using maybe four lego NXT ultrasonic sensors and then using C++ it would display the radar screen on the computer. Or maybe since the Kinect SDK is out, you could use three Kinects and put the same program on each computer, and the Kinects would send the info over the internet to a fourth computer that would put all of the information together. Just a suggestion.

Thanks!
