Hello! I am a master student in France. With a good curriculum after a double undergraduate program between Brazil's best physics program and a France's top engeniering school. I applied to several PhD programs for this fall and the only acceptance I got was at SUNY Stony Brooks for a MA...

I was considering study in America. But the places you have suggested seem a good option too. I will take a good look at them. Thank you!

thanks a lot.

Hello! I'm a undergraduate student in the last year of my Physics B.Sc. I've done a lot of Mathematics in a program at Ecole Polytechnique in France (Master 1 in Physics, european system). I would like to do my PhD in Mathematical Physics, I've studied some Statistical Mechanics and Exactly...

Thank you very much.. Oh! That all really sound horrible guys! Thank you both so much for advising me. Nothing better then knowing it from someone who have been there. Certainly I do not consider it for undergraduating. In this way I see that there are quite good universities here, compared...

No..just one. Oh.. Thanks for your opinion. It is rather good to hearing from a people who is near of the things. Like for a guy like me from Brazil, it might be quite diferente from things here. Just by the way, it was just one. The only point is that they offered two places, one for...

Hi! I took part in the last International Physics Olympiads that was held in Salamanca Spain, and I got a honourable mention there. After that I received an invite about two scholarships, one in Physics and the other in Astronomy that are being offered to the students who participated there...

I am a Brazilian student, just leaving the High School at the end of the year. I am actually at the moment, looking for a good university in the Physics and Mathematics area. I haven't decided yet, if I want to take a course in pure Physics or any Engineering. I would like very much to study in...

Thank you guys. I got the point about the reflection and skin effect. So let me ask more about this. Where I can find some information about the quantitative necessities to this phenomenum happens. Like the espesure of the material and dependence of it is electron density and how to measure...

Hi! I always thought that tunneling was a quantum phenomenum. So another day I found a problem which is about the part of the light that can be transmitted (refracted) even if you send I light beam in an angle greater then the limit angle of two material boundary. By the way looking at a...

Another point I was in need of another topic. About the quantum tunneling that ocurr and about the amount of light that can be refracted in a material either if you send a light beam in an angle greater then the limit angle. Can anyone help me? Or know some material about this? Thanks, Aron

What I mean, I think that the problem mean by this is, that the received signal that is a superposition of the both signals, from the normal transmition trought the air and the reflected one, gets a maximun value, they are in phase, at 8 times per minute.

Hello! I am having a problem with this problem about the reflection of a "radio wave" in the high atmosphere. (ionosphere) "A short-length wave receiver receive two signals from a distant source at 500Km, beeing those signals, one from the normal conduction through the atmosphere and the...

Thank you Mathwonk, I got the points that you talked about. And sorry guys for the last post I was in a hurry so there were a lot of wrong words and signals too. (I had that minuses in my paper here) Also English isn't my native language so. Thank you again, Aron

Hi, I have a problem that talk about the behavior of two liquids in contact and a boundary that appears between them. I am lack of theory about this situation do anyone of you could help me to find some paper of articles that talk about this? Thank you, Aron
