Thanks, I think I've heard of the story. I know some guys did it recently with lasers, if you have a fixed point on the table and the ball breaks the laser you can work out its velocity, you then have to take into consideration wind resistance and the bounce. But as you say each table has a...

Hi guys I have a question. What are the physics involved in roulette? I know you have these: -Spin or momentum of the roulette table -Friction on the ball from the table -wind resistance on the ball -momentum of the ball -And the bounce when the ball finally drops and hits a few groves...

That is still pretty cool, I have a magnifying glass and a broken Playstation, I think you can see what I'm getting at?!

I think your going to end up ripping the wings from bottle during thrust. You could buy the wing, cut it in half hinge them so they pop out at 90 degrees from the fuselage of the bottle. Kind of like when a fighter plane untucks it's wings when it comes out of mach, to make it more stable at...

Yeah the function was called PTT (push to talk). Worked just like a walkie talkie. Don't it worked on uk mobiles though, the function was disabled. I think the function was on my old nokia n70.

The paper was interesting, it's good to know the thought process that people like maxwell went through. And I think your correct in some respect, that you can keep digging too deep into something and lose perspective, but if you don't push the boundaries there would be no progress. Some times...

So mikey, you think its an after effect of the cooling of the universe after the big bang? I didn't know that there were theories that the electromagnetic force and the weak nuclear force were once unified or could be unified if the universe heated up.

Humour me, what's your speculation? I'm interested in what people think.

Would shooting a laser through a magnifying glass actually magnify a beam?

50 physics ideas by joanne baker Introduction to most basic physics ideas. Pretty good read, I'm a carpenter and I could grasp all the ideas. It's what lead me here actually I've got more questions!

Ok that all works in my head. Here's another question, how did the pre existing field get where it is, i.e. the void in space? left over from the big bang?

I think I understand it, an electric field can be induced by a magnetic one moving at 90 degrees to it. The basics of a dynamo, and the opposite is the basics of a motor. Right? So your saying light induces it's own electric and magnetic fields by oscillating them, this then becomes self...

Ok, air molecules who's equilibrium is being displaced is already present before a sound is even made. Is there already an electromagnetic field present before light is even introduced? If there isn't does light provide it's own field with which to travel?

It's a grammatical error sorry, I get that light itself oscillates between magnetic and electric. Maybe you could explain to me how the oscillation propergates according to maxwell. I referred to an ether in the context of a medium in which light could travel through. Sound for example travels...

I'm going to need more information than that, how exactly does a photon or wave both move in a vacuum?
