Hi, I am learning how to do off-plane Earth to Moon transfers (using TransX) and can't find out how to accurately find the Moon's time to node (so I can launch about 3 days before it gets there). I know you can approximate it by just looking at the orbit and launching when the Moon is so many...

Hi everyone, I am looking at getting a new monitor to replace my unspeakably old current one. Budget is around £300. Current contenders are: Eizo Foris FS2333 Asus VG248QE BenQ XL2420T The top one has better image quality but the lower two have better response time, refresh rate etc. It will...

http://www.spaceengineersgame.com/ Only in Alpha at the moment but looks interesting. Sort of like Minecraft in space :)

Hello, I will soon be going to University (physics, of course :P ) and will be getting a laptop. It will mostly be used for work however I would also like it to be able to run games, including (obviously Orbiter) and FSX (although I realise it is a very demanding program, especially with...

Greetings! Does anybody know of any good books concerning classical field theory (Lagrangian formalism etc)? Not on any particular theory in particular (electromagnetism), just in general. ...yep that's about all I've got to say, thanks in advance! :thumbup: Will

Hello, I am reading a book called "Quantum Mechanics and Path Integrals" by the one and only Richard Feynman. When it comes to define the sum over paths it uses an analogy with the Riemann Integral (that's fine) to come up with the equation ∫…∫ ∫∅[x(t)]dx1dx2…dxN-1 I think I can see physically...

Hello, I am reading "Quantum Mechanics and Path Integrals" and the first few chapters are a 'recap' (at least it would be for the age of people it's aimed at) of classical mechanics. There is a section on the Lagrangian and principle of least action etc and the derivation of Lagrange's equation...

Hi, According to Wikipedia (that ever so reliable source of information) the lowest energy state of a proton and a neutron is such that they have opposite spins and this has "to do with the quark structure". I have tried to figure this out in terms of the quark spin but whilst I can see why the...

Hi, When Newton first published his Principia his law of gravitation was at the forefront of scientific knowledge and only the most learned people would know of it, now we learn about it in school. I believe long before that, a person had to go to University to learn how to add things up. Does...

Hello, I am interested in learning more about particle physics. So far the only 'official' contact with it was at AS level physics (I don't believe there is any more at A2) so the next place I would be learning it is undergraduate at University but i can't wait that long! I have also done a bit...

Hello, I have been having a problem for a while and have decided I am finally going to try and fix it. My computer is connected wirelessly to the Home network - with several other computers (some wireless, some wired) and a games console - and occasionally the connection will cut out but only on...

Hello, I have recently taken my AS exams in the U.K. and have the summer holidays very shortly. Does anybody know of any science relevant (observatories, labs etc) around the SE of England I could contact about work experience? I know the odds are slim but I would like to try anyway. Thanks...

Hello, It has been decided that later this year the family will be going to Norway. Does anyone know of any space/science things to do such as a space centre or a science museum? We will be around Oslo so anything around there would be good. Thanks, Will

Hello! Is there a way to accurately predict where the UCGO probe will land? I know it conducts a retrograde burn almost immediately after being released but (tested on the Moon) it then burns again (similar to the Apollo LEM) and lands far short of where the original predicted landing site was...

Hello, Ideas have changed since this initial post see post number 24. I seek guidance from fellow followers of the probe :hailprobe: .I have been given a school project (called an EPQ if anyone cares) that allows me to do pretty much anything and I have decided to design and launch a rocket! I...

Hello, I am completely confused by pretty much this entire section of the forum! Why are there threads for DirectX 9 and threads for 11? What is the point of making it DirectX 9 if it's also going to be Direct X 11? I don't even really know what DirectX does (something to do with graphics)...

Hello, I get the impression that these two are very similar, what are the pros and cons of each? Thanks.

Hi. I did a search for this and found that local light sources is a common reason so I turned that off but I still get a runtime error when trying to load any scenario: "This application has requested the Runtime to terminate it in an unusual way". I have the following addons installed...

Hello. After getting into a stable orbit I tried to align orbital planes with MIR, this is nothing new and I have done it before. After the first burn at one of the nodes both my inclination and MIR's were constantly changing (at different rates) even though the rate of change still said 0...
