  • Help with German Higher Education?

    Greetings, I've been having some trouble navigating around the website as linked (www.anabin.de), which provides information on minimum highschool requirements for enrollment into Heidelberg University, Heidelberg, Germany. (Google Translate just doesn't seem to work, please pardon me). I'd be glad if you could help me with the minimum marks I require in grade 12th of Central Board of Secondary Education (New Delhi, India) by the standards of the organisation (Anabin)? Thanks in advance.

  • How do I accelerate my graphics card?

    I do not, as of yet, consider overclocking for a solution, but my graphics 'wore off' for some reason. It could run games like Test Drive Unlimited and Half Life 2 without a flaw, but now that it lags even on Half Life (1998).

    Aspire 6930, nVIDIA GeForce 9300M GS 256MB, Intel Centrino 2, 3GB RAM.

    Help?

  • A question about relativity, spaceships and mirrors?

    Okay, what would an astronaut in a spaceship moving at 0.75 times the speed of light see on a stationary mirror?

    I mean, would he see his image hurling towards him at 1.5 times the speed of light (you know what the consequences are), or would he just see his image moving towards him with 0.75 times the speed of light (I mean, the image is only virtual; why bother relativistic velocity addition)?

  • Why do Chlorine atoms 'hog' electrons? Wait, doesn't that violate causality?

    You might say 'to become stable'. If you do, here's my question.

    Why does chlorine attract electrons?

    Chlorine atoms attract electrons to become stable.

    Right, so stability is the *cause*.

    What happens when a chlorine atom 'wants' to get stable?

    It attracts an electron.

    Electronic attraction is hence the *consequence*.

    Chlorine attracts electrons first, and then is stabilized. Which implies,

    Electronic attraction occurs before stability. Which implies,

    Consequence occurs before cause.

    Legitimate answers will be appreciated. Thanks in loads!

  • s, p, d, f. Atomic orbitals or subshells?

    I'm really confused; does the notation: s, p, d, f denote the subshell, or an orbital? Rather, does this notation represent azimuthal quantum number, or is it for the angular quantum number?

    For instance, consider 2p. Does this mean 'p' subshell in the 2nd shell, or 'p' orbital in some subshell?

    Elaboration appreciated. Thanks!

  • Do antiparticles have negative mass?

    Well, it's all too hard for me to digest, that a positron or anti-proton bears negative mass. But from what I had been reading,

    "Particles and antiparticles is constantly generated near the event horizon. The particles come with positive mass, and the anti-particles with negative. One from this pair falls into a black hole, and if it's the antiparticle that's falling, the black hole loses some mass".

    Is this the case? Do anti-particles like positrons and anti-neutrons really have negative mass? An elaborate explanation is appreciated.

  • Why is the speed of light 3e8 m/s and NOT infnity? (Please see details)?

    About a couple of minutes ago, I stumbled upon one of the questions by videl, and it was all about "How does light move". Well, it did confused me...

    Mathematically,

    F(force) = M(mass) * A(acceleration)

    or A = F / M

    Since light has no mass, M = 0

    This implies A = F / 0 = infinity for any value of F (which includes 0), which inturn implies that speed of light is infinity. How is this dilemma solved?

    I'd also like to know how was the speed of light determined with such a deal of precision.

    Looking for serious answers. Thanks in advance!

  • What would be the acceleration due to gravity (on earth) if there was no rotation?

    I've seen how "g" is derived, and the rotation of earth is nowhere to be found in the entire equation... The earth rotates about its axis. Doesn't it bring around a tendency of objects to get tangentially hurled off the planet? Okay, so the gravity cancels out that tendency. I don't see this anywhere in the derivation... It's all about mass, Universal Gravitation Constant, and the distance from planet's center... These have nothing to do with rotation, If I'm not mistaken...

    Shouldn't "g" equal 9.81 m/s^2 when the earth is stationary? Please elaborate.

    Looking for serious answers... Thanks in advance!

  • Relativity and speed of light underwater... (Please see the details...)?

    So we know that 3e8 m/s, which is the speed of light is the speed limit of this univese. Can anything travel at speeds of 2.5e8 m/s underwater, when the speed of light there is 2e8 m/s? (Speed of light underwater = speed of light in vacuum / refractive index of water = 3e8 m/s / 1.5 = 2e8 m/s)

    Looking forth to serious answers... Thanks in advance!

  • Light zooms you by at the same speed, no matter how fast you are travelling. What if you are travelling at ...?

    Light zooms you by at the same speed, no matter how fast you are travelling. What if you are travelling at light's speed? Will it pass us by by the same speed? Doesn't this mean that the speed of light (relative to a stationary object) is doubled?

    Or is it the speed of light from local light sources? If it is so, why isn't it included at the theory's statement?

    Please note that I am very well aware of the fact that we cannot travel at the speed of light.

  • What are these unquoted objects in Google Sky?

    Recently, I came across 3 unquoted objects in Google Sky. They are in the same nebula, but I'm confused what are they... These are the co-ordinates -

    44.1504°, 134.673°

    44.1928°, 135.335°

    44.5785°, 135.791°

    [latitude, Longitude]

    Do try zooming all the way in.

    What do you think are they? Is it the work of Google, or the reality?

    Thanks a lot!

  • Why did the universe "expand" and not "contract" in its initial stages?

    Okay, so the big bang theory says that the universe expanded from a primeval atom, which had the mass of entire universe. Fine. Now, its radius was far too less than its schwarzschild radius, so why didn't it turn to a black hole, and shrink to singularity, instead of expanding?? If its because of the internal pressure and temperature of the atom, why doesn't it happen to all the black holes? I mean why dont they explode into big bang once they shrink to that size (or maybe less, depending on the mass of parent star...). If that happens, how come there are no journals or papers on it?

    Sorry for the complication... couldnt help it... Please, real answers.

    THANKS IN ADVANCE!!

  • Why does this happen to me?

    Every night, I just cant stop dreaming about black holes, worm holes and things like that... Every night i go to sleep, I see that a particle and an antiparticle collide to ..... (I would not list the scientific details), and the wierdest thing is that some one constantly keeps on telling me whats happening. I hear voices telling me what i never heard before, and SOMETIMES when i go and check it up (after waking up) in the net, its all true...

    It doesnt end there, as i've been getting many de-ja-vu since about a couple of month ago. also, i keep on forgetting basic mathematical calculations, such as 3 times 7, 4 times 9, etc. I never get a headache, or anything of that sort...

    What could be the reason for all this? is it all because me being an ardent fan of physics?

    or is that inherited? (because sometimes, my mom tells me the things going to happen, in advance. Like, few days back, about an airplane crash in brazil. She told me and my dad 2 days before, that she had been dreaming about thick clouds of smoke coming out of a crashed airplane. there are more...). I'm really confused.
