### Difference between Fourier and Laplace transforms in analyzing data

I have a set of displacement-time graphs from an experiment to convert to the frequency domain. Both the Fourier and Laplace transform seem to do this, so what's the difference between them (...

### What is this equation, written on a wall? [closed]

I've also asked this in MathOverflow, but since the equation in question is related to acceleration and physical phenomenon, I figure this is also a good place. I was asked to ID the following, but ...

I am new to this subject. I am trying to understand what is the purpose of the phase function $$∂u/∂t=-v∘∇u-v( μ_{a}+μ_{s})u+∫vμ_s p_{s} (Ω^{'}→Ω)u(r,Ω^{'},t)ⅆΩ^{'}+q(r,Ω,t)$$ Were u= angular ...

### Why is the impedance of a resistor the same in time and frequency domains if the Laplace transform of a constant is not the same constant?

I'm sure this is a silly question, but if the Laplace transform of a constant is not a constant, e.g. $$\mathfrak{L} = \frac{1}{s}$$ then how come the impedance of a resistor is the same in the ...
