Hello all, We've just begun integration in my maths class and I have a question about a certain aspect of integration by substitution. Let's say for instance you let u = 2x-1. Then you differentiate it and get du/dx = 2. My maths teacher said " you can now think of it as multiplying...

You could also think of it in terms of marbles in a tube. Where the marbles represent electrons and the tube represents the wire. If you push a marble in one end of the tube, another marble will come out the other end almost instantaneously. Even though the marbles are actually moving very...

Thanks :)

Is it possible to create a function that has two values of y for every one value of x, or is this an unbreakable rule of functions?

You don't say. I'll be off to read up on them right now. Thanks :)

Thanks for the help :)

If a constant pressure is kept on a piezoelectric crystal, will it continue to generate an electric field?

How would a curious young gentleman like myself go about supplying power to a Mullard vacuum tube? I have several different types of Mullard tubes, but no idea as to how I can generate the electron beam. P.S. If side-effects of solution include death, injury or Hannah Montana please do not post.

So it's still a fundamental force acting on the particles, drawing them close together which then allows them to annihlate. Now I'm off to find out how annihilation works. Any help from you fellas would be much appreciated.

So, what is the force that acts on particles and anti-particles which causes them to annihilate? In other words, what is the force that attracts them to one another?

Fair enough, thanks for all the help :)

My logic was: a neurton is it's own anti-particle, and seeing as atomic nuclei can exist the neutrons in the atomic nucleus aren't anihilating each other, hence neutrons shouldn't anihilate anti-neutrons. This logic worked for me because I figured particles only annihilated anti-particles...

Do Neutrons and anti-Neutrons annihilate? I can't imagine any reason why they would, I just thought I'd check.

I've been wondering ever since I read about mesons, how they can exist. Shouldn't the particle anti-particle pair annihilate? Or is there something I'm missing from my idea of the meson?

I've been doing some light reading about pressure, but my physics book doesn't mention anything about the unit of pressure Torr. What factors would I have to take into account in order to understand the required pressure for my experiment?
