This is the statement, in case you're not familiar with it.
Let ## f_j(w,x), \; j=1, \ldots, m ## be analytic functions of ## (w,z) = (w_1, \ldots, w_m,z_1,\ldots,z_n) ## in a neighborhood of ##w^0,z^0## in ##\mathbb{C}^m \times \mathbb{C}^n ## and assume that ##f_j(w^0,z^0)=0, \...
Hmmm no I suppose they did not use collimated light back in the day, just white light I suppose. I also know that of course there was no path difference at all since the aether doesn't exist and light has the same speed in all inertial frames of reference, but the only thing I could think of...
I expect fringes to form because of a difference in the path of the two rays, one of them getting to the screen earlier than the other. The rays are collimated if they do not disperse much with distance, but tend to stay coherent and "point" in the same direction. I don't even understand what...
Hi everyone. I'd like you to help me make sense of a question I found about the Michelson Morley experiment. This is it:
"Explain how and why the uncollimated light rays form interference fringes?
Can you say what would happen if the rays were collimated?"
Does this question even make...
I can't stay with her because I owe her, It doesn't seem right, as she could find someone who doesn't stay with her out of indebtment. And anyway, who owes whom? We were together 7 years and we've both had bad moments and good moments. Now it's over but it doesn't mean that those years were...
To the other guys, thanks for cheering me up a bit. I opened this thread because these days I was starting to miss her more and feel more guilty than usual so I was considering to change my desaparecido policy and concede to a meeting. But what next? She'll want to see me again someday soon and...
Hi Dembadon, as I wrote, on the day I dumped I also stayed there an hour and a half to give explanations.
To answer the other question, yes we had already talked about it but she hadn't changed and it was the controlling side of her that bothered me the most; things had to go her way otherwise...
Hi guys, thanks for your replies. My description of the event was somewhat brief. The night I drove to her and told her it was over I stayed for about an hour and a half during which I obviously exposed my reasons (I don't feel any close to how I used to, your personality is a problem, etc). She...
I have been with this girl for 7 years, and known her for 12. Things hadn't been completely right for a long time but lately, say in the last year, they got worse. We argued frequently because we both have kind of strong personalities. Ultimately though, I decided that some of her personality...
I know this is not what you asked but personally I advise you to stay miles and miles away from trying to please your father by making a life changing decisions on his behalf.
WP article about radioactive decay is too detailed. All I need is something that links a "potential well" situation to the half life of a substance, for instance.
Can anyone link to a synthetic and understandable explanation of radioactivity through basic quantum mechanics? It does not need to be a comprehensive explanation at all, examples or partial explanations are fine. Online class notes are welcome but so are books suggestions.
Thanks in advance
This. I know a lot of people who went to Med School with various results. I second the suggestion of not underestimating it. Don't think that just because there won't be any proofs or difficult exercises to solve it's going to be a cakewalk. Expect to have to learn LOADS of stuff by heart. Long...
Hi HallsofIvy, this vector is something similar to what I got (with inverted signs though, I probably did the cross product wrong). I don't see why it should have norm 1 in general, though and i need it to have norm 1 (Sorry, I just found out I should have written UNIT normal vector in the...
Suppose you have a single variable differentiable function r: R -> R restricted to an interval, like [0,1] for simplicity, if you want. Consider the surface of revolution obtained by rotating the graph of r around the x axis. How do I find the NORMAL VECTOR to the surface at each of its points...

They all come up. The standard euristic solution to the cauchy problem for heat equation IS a convolution of. The dirac delta comes up especially if you mention distributions, so pretty much everytime you hear about "fundamental solution(s)" etc.

You made me wanna cry man. I mostly see parents who are overconfident about their spawn's potential and sometimes to the point of embarassment, but seeing someone your age so disillusioned with his father's opinion of him just doesn't seem right.
