Hi,
I've been given a problem to solve and I was hoping for some pointers.
To start with we have a surface which is originally represented as a Bezier patch, a peicewise set of bi-cubic bezier surfaces. It might be important to mention that the surface is "fairly two dimensional", the surface...
Trying decide, apropos that famous Feynman quote, whether there is a 'real problem' with quantum physics. My own rather inexpert view is that if there is, the it's something to do with the classical limit. (The measurement problem being an interesting special case of this.)
In particular...
Beginning another attempt in my amateurish efforts to understand quantum mechanics, I suddenly realized there was a basic issue I find completely unclear.
When we solve the SE for an interesting system we first need to input a potential, which is usually some function of the spatial...
Thanks for your post. However I should have been a bit clearer in my original post, the surface I'm trying to find my back to is not a cone as such, it's actually a set of bezier patches which are just cone like. (So I don't think the angle of the edges can be that informative.)
I doubt...
"unflattening" a surface
Hi,
I have a strange problem to solve. Imagine having a surface defined in 3D, say for example a cone, pointing up in the Z direction and sliced in half through the Y-Z plane.
The half cone is then sliced further into a number of sections with horizontal cuts...
I suppose there is some sense reading that paper of it being a slightly artificial attempt to get a language to do something it wasn't designed for. I'm not so sure though. They point out the benefits of Java, i.e that it's simpler for new programmers to learn, that it has a centralised...
Hi,
I'm interested in pursuing a career in computational science and numerical computing and so on. I'm looking for some fairly general advice on how to direct my studies. I started learning programming in java, which I very much prefer to program in these days, having had some exposure to...
Demystifier,
Quantum Mechanics is (or might be) an indeterminsitic theory, not a "random" one. In your opening argument you make the standard mistake of thinking that the randomly determined events have to constitute the free decision in of themselves, we can be more imaginative than this...
Hi,
I'm thinking about whether to try for a Phd or not and am having some doubts. I have quite a few reasons for wanting to do it, most of these are quite broad and general though, and I've yet to settle on a specialism that I'm certain is right for me. I think I'd like an academic...
A simulation I'm running takes the density as an input when preparing the system and I'd prefer not to have to measure it experimentally so it would be really useful if this was tabulated somewhere. I was looking in the Handbook of Chemistry and Physics, but L-Proline has no entry in it's...
It's very much an introductory course I'm doing so much of the rigorous maths was skated over, although some arguments were made for the reasonableness of the selection rules. The set of rules for total angular momentum change for allowed, first forbidden etc, though were just quoted, I got...
Hello,
I'm having a hard time understanding some aspects of beta decay and I wondered if someone could help. (Perhaps this post belongs in the homework forum, but i don't have a specific question to do as such.) I'm not being helped by the fact that my general understanding of angular...
I wonder what Mr Feynman can have meant. On the face of it this seems outrageous.
I was under the impression that the different formulations came with their own mathematical structures.
Hello,
I've been stumbling across interesting articles about water recently, such as:
http://www.lsbu.ac.uk/water/index.html
http://physicsweb.org/articles/world/16/5/7
For something so apparently simple and ordinary and essential for life in a few different ways to be so full of...
