I like Star Wars! More spesifically I really like the Bane triology. I have long been really fascinated by the sith and the ways of the dark side. This triology is from the old republic era and covers Darth Bane's journy from a cortosis miner to a dark lord of the sith. He learns that the...

Very good point, this is the kind of answer I was looking for. Thank you.

no, sorry, I'm not too good at explaining exactly what I mean. This is why I was not quite sure where to put this. I'm not looking for any justification, I know what it is, why they use it. I really just wanted to take that idea into the real world and see how it really is.

I didn't really know where to put this, so I just put it here. What I wanted to discuss was the following: often in sci-fi movies or series they have the capability to travel faster than light one way or another. Whether it is by means of FTL, hyperspace, wormholes or whatever they always...

Don't worry, I didn't :) I just forgot to write it here :)

Sooo if I say: ∫(x+2+3)/((x+2)^2+4)dx and substitute x+2 with u, and dx with du ∫(u+3)/(u^2+4)du am I on the right track? I'll have it done in a minute and check the answer. thanks. ************EDIT**************** lots of stuff happened and then: 1/2 ln((x+2)^2+4) +...

Hey! Need some help on an integral I've been trying to solve. I haven't been working enough with my math, so I am working on catching up before finals.. I was working with partial fractions and u substitution when I couldn't figure this one out: ∫(x+5)/(x^2+4x+8)dx it's not that hard...

Thank you. :smile: I really find physics quite interresting, and I have been doing some thinking of my own. I don't have much of an education though. I'll be 20 years old in october, and I've had 2 years of basic physics. Now this particular task puzzled me and really got me to wonder what was...

I had a physics test at school recently. One of the questions was based on the equivalence principle, going something like this: Two clocks in a spaceship that is accelerating. One at the bottom and one at the top of the space ship. Now think that the spaceship is so far away from any object in...
