I am sick of skype. It doesn't let you turn off history on iphone/android, and the history saved there comes flooding back to your PC when you start skype there. I want something that I can talk with, preferably without saving history at all, but at least having an option of turning it off...

Hello everyone, and Happy New Year! :wink: As you have probably already guessed, this New Year is especially important for me since it is the time when I fill the applications for US graduate schools on Physics. I am more than a little bit worried about my chances since, in case I won't enter...

Got offered a dean's award from here - http://roanoke.edu/ What do you think of their physics program?

I'm making a program that interprets and evaluates equations. I won't go into all the specifications, but basically it would take a statement like [FONT="Courier New"]~1^(2~&3) 0x3FFE 0x2FCE 0xFCC1 and returns [FONT="Courier New"]4926 (0x133E). As you may have guessed, the...

I am looking to transfer from community college, and my school options are limited due to finances and my poor academic background. My only options so far are some unknown schools that are not even ranked 100 in the state, and they don't have any money to perform research. So I will probably not...

Homework Statement I've written some C code that models the motion of two masses attached to a wall (and each other) by springs like this. The output file is 5 columns; the time, and the positions and velocities of each block at that time. I'm not sure how to visualise my data...

I am having this doubt for a long time and want to clear once and for all. Here are the questions: - 1) What is the difference between program and script? (I believe program is run on a machine while script is run on another software but still I want your answers in case I am wrong) 2) Why...

I hope I'm in the right section. This part is not important but this is thought behind the program. If you have n-mathematicians and each has a secret number. How many phone calls have to be made for all mathematicians to know all numbers? In this brute force approach I, hypothesize that you...

I'm an undergraduate studying math and will be applying to grad school in the future. The top graduate programs are MIT, Harvard, Stanford, Princeton, Berkeley and Chicago. However, I doubt I would be near the top of the class at these places (if I got admitted, that is). This could have a...

Okay, so I am an international student (i.e not a citizen or resident of the U.S or Canada), and will probably need some financial aid. That makes it a lot harder to get into MIT from what I've heard. Anyway, is MIT even a possible goal for me, or am I being over-ambitious? Here are some of the...
