Here is my sophomore school picture from this year

I'm not sure if this is the right subforum for this thread, but I was wondering what everyone's opinion is on chi energy (AKA qi), specifically the role it supposedly plays in martial arts and medicine. Is there any science to this, or is it just an ancient belief that hasn't completely...

I think we're kind of getting off topic here. So, the reason why the book's expression for relativistic KE gives us a value 20 quadrillion times greater in my example than the non-relativistic KE is not that the expression in the book is incorrect, but that it includes the rest energy? Why...

If the expression I gave above is incorrect then there is a typo in the book because that is exactly what the book has in it - I double-checked.

I am reading "Relativity" by Einstein right now, and I came across a formula he gave for kinetic energy in accordance with his theory of relativity. He says that "the kinetic energy of a material point of mass m is no longer given by the well-known expression .5m(v^2) but by the...

I'm the same way on the piano. When I'm trying to teach my friend how to play a song, if I go slow and dissect it for him, then I have trouble. I usually have to go back and play it at normal speed without thinking. A few days ago I was listening to a voicemail message on my cell phone...

ahh I see. So that would just be another paradox showing WHY you can't treat infinity as a number then. right?

Given infinite time, can one do infinite tasks an infinite amount of times? How many times can one do infinite tasks in infinite time? One would think the ansewr to that question could not be >1, for that would mean that the tasks must have an end and all of them can eventually be...

Awesome! I posted some cool videos on your thread, and here's one more I just found... http://video.google.com/videoplay?docid=2040423001461844580&q=david+belle Some of David Belle more amazing stunts

Here are some awesome videos of Parkour and David Belle, its founder http://video.google.com/videoplay?docid=7410780648438568268 &q=david+belle http://video.google.com/videoplay?docid=7834855742079548500&q=david+belle...

Sometimes it seems like the other way to me :) Men are always expected to hold the door for women, hold a woman's hand while she's stepping down off something, etc. Women aren't expected to hold the door for men lol. Does this encourage equality?

wow, thanks, you're completely right. I'm sorry, I'm very tired and I mixed up the plots (it's 4:30 am here) I'll edit my first post
