Don't worry, it's not complicated if you already know what sine and cosine are. It'll take little time to grasp the concept and apply it to your code.

Ok, it's much simpler than it seems, but extremely important if you want to work with x,y,z and define angles. In the celestial sphere astronomers define the celestial equator (a projection of Earth's equator) and the ecliptic, which is the apparent motion of the Sun through the sphere during...

Not sure what you mean by this, but at some point you will need spherical coordinates. From your code it looks like you have a good understanding of trigonometry so this shouldn't be a problem. One possible cause of confusion is reference frames. Have you defined one? If so, which? If not, do...

Thanks for the tip!

Some sites do use headers for that, but it's very few of them and in most cases that's just for protecting copyrighted material (e.g. videos). So most likely you won't have trouble. If you notice that it doesn't work (and you're not doing any nasty things) I'd suggest you use netcat in server...

As far as I'm aware of the only mandatory header in HTTP 1.1 is "Host: ". However it might be better if your script can also send appropriate headers to define the encoding, and request the TCP connection to be closed or kept open.

I was assuming your photons are traveling in an Alcubierre drive :p Thanks for the awesome explanation.

In Fundamentals of Astrodynamics by Bate, Mueller and White, ISBN 0-486-60061-0, I can see the following equation: dt = 2/h dA h is the specific angular momentum, given by h = r v sin(γ), where γ is the flight path angle, i.e. the angle between the r and v vectors. This is consistent with...

Hello everyone, I'm new here. I'm a space engineering student and every time I learn something 1000 new questions come to my mind (as usual with science!). Most of my education was from an industrial (practical) point of view, so I feel very, very curious about the science behind the...
