Greetings PF, I'm a computer science student who is tasked with a robotics project. I've got a 2-wheeled robot (there's a 3rd dummy wheel on the back to prevent it from falling over) that turns like a tank, by means of turning one wheel faster than the other. If both wheels are the same speed...

Trying to solve this infinite series?? Hey folks! I've spent hours trying to solve this and have exhausted all available resources.. I just need to be pointed in the right direction! Homework Statement Compute the sum of the infinite series (I believe this is an arithmetico geometric...

Hi all, I have a question about calculating the orbitals of bodies of mass in space (Newton's basic laws). I am writing a program to simulate the orbitals of bodies in space -- basically, you define the object's mass, size, location, and initial velocities and watch how they interaction via...

Wow, that's really impressive! A laser rangefinder seems to be the right solution.. I'll have to do some research into where to buy one and how you could posibly incorperate it with a software program. All I find when searching for them are hunting binoculars. :P Can anyone help me out with...

My idea is to create a flotation device that would have a strong electromagnet at the top, this pulling objects upwards, just enough to cancel out gravity. A computer software will determine how much power to send to the electromagnet by knowing exactly how close the object is to the...

I know this is a long post, but bear with me.. this is what I've got through several days of reserach. I've always woundered about the mathematical aspects of evolution. I've heard such facts that the mutation rate is fairly consistant and can be used as a biological "clock" to track events...

You and a friend riding a train at 40 mph. Your friend asks you to toss him some object.. ah, a cell phone. Don't drop it, lest it break! You underhand toss it at about 3 mph, he smoothely catches it. An observer standing still in the subway terminal, waiting to catch their train, sees you...

Wow, this thread is certiantly turning into a train wreak.. always nice to see that happen without someone wanting to stop it :rolleyes: Short answer: Let's define "time travel," according to Special Relativity, to be observers experiencing different amounts of elapsed time due to your...

Wow.. it sounds like you have quite an idea there! I am highly impressed by your ambition to want to turn your project into a reality, dispite still being in high school (correct?). Have you considered, if you were to "launch this into orbit," that it would be in a non-gravitational...

There really is no viable alternative to the theory of evolution itself. With that said, there is definatly room for development in the theory of evolution. Evolution is an observed fact, falsifiable and testable to a certian degree (microevolution of bacteria, for instance). I think the only...

I don't have any sources to back what I'm saying up, but I have heard that scientists are locating genes that determine the regrowth of limbs, etc. The salamander is a perfect example for this quality in a species.

heh, yea October 7th is by birthday :P that would be a good combo. I googled and found http://www.anl.gov/Media_Center/News/2006/news060905.html Sounds like you's have a lot going on over here. I actaully live in Waukegan, which is about 56.8 miles (according to google, heheh). It's...

Thank you all for you're replies :P I guess physics and computer engineering would go good together. I'll talk to a counsoler and see how that would work out at my community college (transfering to a $50,000 college afterwards scares me, heh, but I guess it must be done). Four more...

Programming vs. Physics -- Career options; Well, I'm 17 and am going to graduate college soon. ever since the age of 15 (when our family finally got a computer), I got very involved in programming and living in the "internet scene". For those of you who don't know what the "scene" is, it's...

As a preface to my question, I am in no way asserting a FTL posibility which violates the posulates of Special Relativity. Throughout several online articles and books that I have been reading, there has been a referance to some sort of warping of spacetime that allows you to, in their words...
