What maths is involved?
Calculus
Graph Theory
Group Theory
Linear and non-linear algebra
Fourier Transforms
Vector Calculus
Trig
...
...
...

I could go on for ages, most mathematical concepts eventually find some application in science.

What are Fourier transforms? I have to do that this year coming.

It's basically a method that splits a waveform into components called sinuoids (or something like that) which when summed equal the total waveform. Spectroscopic techniques (such as infrared and Nuclear magnetic resonance) use these transforms to add together various bits of information collected by the spectrometer and create a spectrum (which is the total waveform) - it's much more accurate than non-FT techniques. I'm afraid I'm a bit ropey on the actual derivations!

Have you done Fourier Series?

Nope, we do that this year as well.

Nope, I assume we do those this year as well. All I know is we do Fourier *something* .
Oh, can't explain Fourier Transforms that way then

P.S. Since you are a physicist remember this, the FT of a Gaussian is another Gaussian You'll probably need that for Quantum Mechanics next year

Don't worry, I looked up both Fourier Series and Fourier Transforms on Mathworld. They look complicated . Oh boy, I don't even know what a Gaussian is!

Hey Nylex, do you need to know about Polar Co-ords for first year physics? just not sure whether to bother with that P4 topic, or move onto P5 once I've done 2nd order differentials.

Thanks

In my course we didn't, check with elpaw about Oxford though .
