I'm going to be linking fractals and chaos theory to life and the universe, so what about something along these lines: universe is chaotic; changing the initial 'parameters' would result in a totally different universe. universe is like a fractal - infinite and similar complexity on every...

The reason I say synonymous is that whenever you google chaos theory, you almost always get fractals too.

I'm doing a presentation in a few weeks on fractals and chaos theory. To me, their link is more intuitive than mathematically/physically sound, and I'm really struggling to put the link into words. I've tried googling it, but no where seems to give a satisfactory explanation of the link...

oh of course! :D I feel a bit stupid now :P I guess they're shifted up by ln(a) right?

It's easy to show that \frac{dy}{dx} of y = ln(ax) where a \in ℝ, a > 0 is always \frac{1}{x} : y = ln(ax) y = ln(a) + ln(x) ln(a) is constant so its derivative is 0, and the derivative of ln(x) is \frac{1}{x}. Hence: \frac{dy}{dx} = \frac{1}{x} Attached is an image of y=ln(ax)...

I don't quite understand this phrase: "the COR increases from zero to unity as the stiffness of the happy ball decreases from infinity to zero." or indeed it's implications.

I've been told that the coefficient of restitution is a little like friction; it's a measure of how elastic a collision is between two objects, it's not an individual property of each object itself. Now let's say you have two balls bouncing on the ground. Ball 1 has a coefficient of...

ok thanks I'll have a look at that :)

It reduces the frequency of errors

It is stable on average, but it's not just changing by the odd joule it's in the order of a kJ the first time. Once it happens once, then it begins to increase at an increasing rate. I won't say exponentially though because it is still random. When I change the mass of one molecule then the...

This one's aimed primarily at the programmers in this forum. I've written a programme in python (Set as a long term project from my A-level physics teacher) which will hopefully end up being a scientifically accurate ideal gas simulator in 2D - I'll set up a bunch of particles with random...

Thanks a lot for all your answers :) They've definitely cleared a lot of things up for me :)

Thank you so much for you answers, they're very helpful :) "It turns out that, if the orbitals 1s, 2s, 2p, 3s, and 3p are all filled, a 4s electron will see a higher effective charge of the nucleus than a 3d electron, hence E(3d) > E(4s)." This is a convincing explanation as to why the 4s sub...

Let's say the river's speed is 1 kph and the boat's speed is 2 kph then the boat will travel downstream at 3 kph and upstream at 1 kph. So when you go downstream you add the speeds, but when going upstream, you subtract the river's speed from the boat's speed. Try working that backwards.

Apologies for the long post this is going to be, but at the moment I am doing A-level chemistry and physics, and I am learning about electron orbitals and quantum physics at the same time, so I have reached a state of confusion. (At a higher level than that required for the A-level; I'm not...
