1. ### Becoming a mathematician - I am so depressed

Very sound advice, though i doubt the op will take it or even admit to himself he has such issues.
2. ### Implicit function theorem for several complex variables

I can't edit anymore, but of course the x in in $f_j(w,x)$ is a typo. It should read $f_j(w,z).$
3. ### Implicit function theorem for several complex variables

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, \...
4. ### Question about Michelson Morley experiment

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...
5. ### Question about Michelson Morley experiment

Thanks. Do you have any reference for this? I don't think I can work out the answer from these hints.
6. ### Question about Michelson Morley experiment

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...
7. ### Question about Michelson Morley experiment

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...
8. ### Sense of guilt for leaving my girlfriend.

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...
9. ### Sense of guilt for leaving my girlfriend.

Ok I guess I'll just keep to myself like I've been doing.
10. ### Sense of guilt for leaving my girlfriend.

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...
11. ### Sense of guilt for leaving my girlfriend.

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...
12. ### Sense of guilt for leaving my girlfriend.

hmmm, no she is 27. And I don't think I disrespected anyone's womanhood.
13. ### Sense of guilt for leaving my girlfriend.

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...
14. ### Sense of guilt for leaving my girlfriend.

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...
15. ### Programs Minor or Second major in physics

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.
