Hello astronomers and physicists! My name is Ahmad. I'm Lebanese studying in Dubai, majoring in aeronautical engineering. I'm usually very curious about everything concerning physics, and not only aeronautics. So expect questions concerning various areas of physics. I'm also sometimes Mr...

Hi everyone. I'm Sam, I am not a scientist. I build machines for fun and often find myself wishing I had paid more attention at university. So I guess I might be asking a few questions. Hopefully some of you might be able to spare a few minutes to point me in the direction with a couple of...

My interest in physics stems from my love of astronomy. I am a management consultant by profession, but it could have been an astrophysicist instead! I have studied engineering and management. Lately I have discovered very good astronomy courses on MOOC sites as well as podcasts. I plan to keep...

Hello, forum looks like it has good help and I'm certainly in need of that :S I'm currently working on some pretty basic physics / mechanics stuff, Newtonian stuff (up to lorentz transforms) Re the formatting of this place - I was wondering if an appropriate way to ask a question would be to ...

I hope I'll be able to use this forum to get help in my AP Physics 2 class, which I'm currently struggling in. I know a lot of you here are really smart, and I hope you don't get annoyed by newbies like me asking rookie questions.

I selected the Name "Rogue Wave" because I do a lot of boating. Rogue Waves have recently been accepted into the scientific community as a fact of nature. For centuries sailors and captains have spoken of them but, was considered to be "Tales of the Oceans". Science does move at a very slow rate...
