Are you telling me its that simple? Could you go a little further?

Homework Statement dx/dt = -xy dy/dt =-xy find x(t) and y(t) The Attempt at a Solution Using Maple I've plotted the vector field and solution curve for a list of initial conditions. When I tried to work by hand I could find a way to uncoulple the equations. Is there an...

Board or bone breaking in G. Physics is due to impulse. The longer the hands maintain contact with the surface of the board the more damage inflicted on the hands.

Dim-Mak could work in theory. Pressure points describe either bundle of nerves, arteries in the neck, thigh, and arms. If one hits them precisely you can do some serious damage. One pressure point is a bundle of nerves located just under the arm can be "shorted out" when its struck. Our...

I've studied martial arts for a number of years and I can say there is no magic to avoiding the sword. I'm very skeptical. Here is my reasoning: First, the students and masters can train constantly. They can develop a rhythm like dancers and move in a pre-determined way. Martial art forms...

I'm working on a presentation on Quantum Computing. I'm an undergrad but maybe this will help. The paper is called an Introduction to Quantum Computing for Non-Physicists by Eleanor Rieffel and Wolfgang Polak. They provide an excellent overview on quantum error correction. In my humblest...

Thank you for the replies. Is there a way to peform the operations without disturbing the system? Does Deutch's algorithm solve this problem?

How do quantum gates work and how our they different than classical gates?

I'm taking a course that requires me to come up with a research project. I'm officially in my sophomore year and I'm a Physics Major with a fairly broad exposure to electrical eng. and some advanced math courses. That being said... I'm very interested in computer simualtion of quantum...

Some of what you need to know about semiconductors: http://humor.about.com/gi/dynamic/offsite.htm?site=http://www.britneyspears.ac/lasers.htm I also recommend the The Art of Electronics by Horowitz for a much simpler explanation.

How did you arrive at your solution?

There's no way you could've gotten that answer. I plugged in the inital and final velocity and the duration of the acceleration which was 6 seconds. The units check out. My results: 9.2 m/s at 19.5 degrees

Try the equation: V_f = V_i + a * t Vf= Final velocity Vi= Initial velocity a= accelration t= time

This website is my favorite(next to this one) of all timeSOS MATH

The folllowing is from the NOAA website's Hurricane Research Center. Why do tropical cyclones' winds rotate counter-clockwise (clockwise) in the Northern (Southern) Hemisphere? The reason is that the Earth's rotation sets up an apparent force (called the Coriolis force) that pulls the...
