Hi PF,
I am looking for some advice on textbooks or lecture course material that covers cyber security. I know it is a broad topic so as my background is in physics, I guess beginning at the introductory level would suit me best.
I am interested in texts that include mathematical approaches...
I have a simple question about the general solution to Laplace's equation in spherical co-ords.
The general solution is:
u(r, \theta, \phi) = \sum^{\infty}_{l=0}\sum^{l}_{m=-l}\left(a_{lm}r^{l} + \frac{b_{lm}}{r^{l+1}}\right)P_{lm}(cos\theta)e^{im\phi}
(where the a_{lm}, b_{lm}...
I am having trouble evaluating the Legendre Polynomials (LPs). I can do it by Rodrigues' formula but I am trying to understand how they come about.
Basically I have been reading Mary L. Boas' Mathematical Methods in the Physical Sciences, 3E. Ch.12 §2 Legendre Polynomials pg566.
In the...
I was just wondering if there was an identity for such an expression. (Looking at thesage's post, it was a silly assumption; i should have remembered that expansion!)
It stems from trying to prove that [\hat{H},\hat{x}\hat{p}] = [\hat{H},\hat{p}\hat{x}].
I did get this proof in the end. I was...
Just thought this could be a cool little thread.
When reading over Physics or Maths theories, often getting bogged down in the literature, I love putting a face to the ideas and theories which were often hard to swallow for many of the scientific community at the time. Seeing a picture of the...
