No problem, and thank you for discussing. If it makes things easier, https://airlich.wordpress.com/2015/06/08/ellipse-in-polar-coordinates-is-obvious-right/ is a recent post from my blog, and my posts would be in this fashion. They would be mostly about mechanics, though. The post I am...

I am not really looking for a particular space. I would like to open a thread in the classical physics section of the forum. Only, it wouldn't be a question, it would be various things I have to say. I'd like to try and open it if you don't mind, and if you feel the content is inappropriate...

The way it is done in game dev, and the way I would do it in PF, is having one long thread. Inevitably, it will be mostly me posting. But (hopefully) once in a while others would jump in and comment. In thr meantime, thr views counter would count up. I think knowing that someone might read this...

As a graduate student in applied mathematics (solid mechanics, elasticity) I find the process of writing difficult and I have been getting better at it progressively and very slowly. But as a hobbyist video game developer, I have opened a "work in progress" thread on my game in a game...

Guys, thanks for the replies! Greg, I am using Unity 3D to develop it, but I'm not sure yet when I am comfortable (i.e. sufficiently bug-free) to put out a demo. Dipole recommending dipoles. Haha, I liked it! Dipoles (or multipoles) are interesting and have crossed my mind but I have not yet...

Hey guys, I am working on a video game which is based on electrostatics. You play a charged sphere and you can change its charge to interact with other charged objects, sticking to walls and ceilings and orbiting around other charges etc. I am curious what you think of the concept, and which...

Hi, I have been trying to find analytical solutions for a finite rectangular sheet, say, in the xy plane, with dimensions a and b. Assume it is uniformly charged. An excellent (and short) description of the problem is here. The three integrals for Ex(x,y,z), Ey(x,y,z) and Ez(x,y,z) given on...

Thanks berkeman! No, I don't have a PhD yet, I want to start in Fall 2012. I am interested in General Relativity. But programming and visualising is always helpful.

Hey guys, I am running a homepage showing programs I created, as well as some artistic endeavors: www.airlich.de Within the next couple of weeks, I intend to write many emails asking informally about the availability of PhD positions. I am going to keep these emails short and won't cludder...

Hmmm... Two contrary statements: Which one is it?

How come? I know at least three European countries where PhDs in Physics take 3 years (as a standard length), sometimes extending to 4. Why "4-6" in the US?

But I intend to go there with a Master's degree in my possession (from Cambridge). I assume 5-7 years is a program you would start right after finishing your Bachelor's. But that's not what I am aiming at: By the time I intend to go there, I will already have a 3 years Bachelor + 1 year...

Hi, I'm interested in what a couple of researchers do at MIT and Caltech and I would love the idea of doing a PhD there (theoretical physics). But I don't really know anything about the application process for a US PhD program, so here's a list of questions: How long would a PhD take...

Ah OK should have been more clear on this: Of course I never listen to that stuff without having the book, with all the figures etc. in front of me. I also pause the recording when contemplating a figure. As to mathematical expressions, when they're too long when there are too many of them, I...

Hi, I am a Master's student in mainly theoretical physics. When I studied in my Bachelor's, I really didn't enjoy the examns very much: I had a systematic clockwork learning style for preparing myself for the examns. The result is that I usually get the desired (very good) grade, but...
