Then allow me to suggest the following: 1)Wait until a *real* girl has a bad day. 2)Offer to help her with her math. 3)Ask her sensitive questions until she starts crying. If you can't take it from there, proofs aren't your only problem. :smile:

I think you either misinterpreted my post or are jealous :-p All I'm saying is that given time, effort, and determination, there isn't anything one can't understand (aside from religious issues). It's the fear of not understanding that does the damage. Say you have a very nasty...

As far as feeling that I'd never understand Mathematics, No, I've never had that feeling. I have been terrified of it,. though. I've been so afraid that I only thought I knew it that I couldn't do my homework, or wouldn't answer a question. But, no, I've never been unable to understand...

Chifos: I refer you back to Self-Adjoint's post and Gokul's response directly below it. A photon does, indeed, have momentum, although defined in a different way. In dealing with conservation of "___blank___" issues, however, one looks at the whole system and does not zero in on a single...

Skywolf, Are you currently in school? If so, many, many arrangements can be made by the faculty to "zoom you through", including, at many schools, independent study math courses to give you the pre-calc background. If you are not in school, or if you'd rather do it on your own, I could...

What I'm trying to say is that all math, whether we like it or not, comes directly from the world around us. All of the laws, all of the postulates, all of the calculi, everything. So there is *always* some kind of correspondence to the physical world. If you want to try it, try thinking of...

On page 4 or so. . . I can't let this one go, sorry. In your "pie" problem, what about negative numbers? Pieces one already ate? What physical correspondence is there? I have yet to understand people's objections to complex numbers (including my husband's.) A complex number makes sense...

Paul, just make sure you say "what *are* the chances", and not "what is the chances", or "What is the chance?" singular. That whole subject-verb agreement thing can put a big dent in the impact of said poster. At college, we had a pi-day. I was going to set up e-day the next year, (Feb 17)...

http://electron6.phys.utk.edu/qm1/modules/m2/step.htm Nor do I, but here's a jumping point if it'll help. . . my brain doesn't work after 1:00am EST :biggrin:

Actually, Mish3, I looked at the link, and it is very unscientific. It talks about experiments performed by___ at ____, but doesn't say which experiment or when. Plus, sorting through the spelling and grammatical errors in the text is a nightmare. I'd say stick with sources you can actually...

Speaking of ZapperZ's Journal: I always enjoy reading it. I will look for this book, even if I have to set aside cash for several months to actually buy it. I'm trusting your judgement with my limited funds, ZapperZ. And, yes, eigenvectors, -values, and -spaces are in QM, too. Like, in the...

In the Beginning. . . I wished I knew all about Fourier Transforms, all of the basics from linear Algebra (inner product, bases, orthonormality, etc.), familiarity with the more common second-order differential equations, everything about Hilbert spaces and vector spaces (also found in linear...

Interpretation Vs. Theory Kurious, First of all, I applaud your curiosity. I think if more scientists listened to you, there might be some more inspiration out there. What I think is happening is mistaking interpretation for theory. Although colloquially we use the term "theory"...

Hey, I'm just learning this myself--I had to review all of the way back to linear algebra, so I've been spending a lot of time looking these things up. The problem is, since I'm new to the in-depth mathematics of it, I'm not sure which definitions or terms poolwin needs.

According to wikipedia, arildno has it backwards. http://en.wikipedia.org/wiki/Functional This says the functional is a special case of operator. Furthermore (as I am also learning QM on my own), My notes from Introductory Quantum Chemistry by Victor S. Bastista, state that an...
