yea thanks for all the help... I'm going to study physics at degree next year!

so are you lot physics students? Or just have great interest in it...

thanks a lot for the help, I get it now! :)

I have just read the book Three Roads to Quantum Grabity... but my mind has gone blank, the three methods are string theory (M-Theory), loop quantum gravity and one other. I can't remember the last :(:( Any help would be great.,..

lol, doesn't really make sense. If you kick a ball head on ie perpendicular to the ball, then the ball will not spin. Unless there is unequal amounts of drag acting on either side, which is not really possible. The reason why a ball will spin is that the foot does not hit perpendicular to the...

surely in continuous space you CAN draw a perfect circle. i think haha

ooo i get it now, if space is discrete there is no such thing as a circle so the formula doesn't apply! Cheers for the help! So space being discrete hasn't been proven? I read the Three Roads to Quantum Gravity and the author put across that is was definitely right.

so if it is discrete then pie would be rational?

I've been reading that it is, there is a smallest volume of space, if this is so then there is also a smallest length. So what i was wondering is that if there is a smallest length than any length could be measures exactly, like the circumfrence of a circle and the diameter, so if...

well personally i think momentum has nothing to do with it, at all, i am mp wrong, but the initial energy of the bullet ie the k.e energy is more important, as the how far the arrow goes inside is Resistive Force X Distance which will equal the K.e before so if you increase K.e then you have to...

so if it doesn't have mass why can it not escape from a black hole? why does it experience gravity?

also eat(D1cos(bt)+ D2sin(bt)) what is that equal to? zero? Thanks for all your help

ok so i get that, abit, but does that allow me to plot a curve? or can i solve the equation for k?

I am doing an experiment on the pendulum, and i wanted to do something on the damping, i understand a little as i have done some reading on it, the picture attached show the working i have done, i have reached a second order DE and i know little about this. So my question is, can you plot a...
