No, not this one. It was more general.
ad) Robert Geroch's "Mathematical Physics"
No, I don't think so. But I have never seen his book (and it isn't available in my library), so i don't know for sure.
It might have been somewhere on arxiv... but I couldn't find it or wouldn't know how...
Hi guys!
Today I remembered that I used to have a fantastic image (like a flow chart) about different parts of mathematics and how they are connected. In the final stage (at the top), they were connected to QFT and GR.
It's down->top, at the lower end were basic mathematics (sets, boolian...
Well, a bit off-topic, but I got a question about the Master, MSc and MA:
Does a 4-year MSci Physics course (from a place like Imperial) compare to a German Diplom? (now being called Master, for which you need about 5 years)
mish_mash, what are you doing now? what have you been doing after finished this MSci course?
I will start as undergraduate at Imperial this fall and I was thinking to switch from the 4year MSci course they offer for undergraduates to a 3 year BSci and then do the MSci Quantum Fields course. Is...
If you do your PhD there, you are employed by the university and get paid. (between 50 000 und 80 000 CHF per annum)
But I never heard that someone had to do a German test when they want to do a PhD (for Undergraduate this may be the case). But you need to do one if you apply for...
Ok, in this case it will be rather hard for you to master German (because Cantonese/Chinese has no internal structure comparable to German). In this case I'd suggest to go for graduate studies to ETH Zurich (Master or PhD) where all lectures are in English.
I'm currently considering studying at ETH.
It's one of the best universities in Europe and in the world. Its focus is on natural sciences, mathematics and engineering (ETH = Eidgenoesssische Technische Hochschule = Federal Institute of Technology)
The first two years of undergraduate level...
Hi there
Lately, I have been irritated by some general articles about the Higgs Mechanism in newspapers. Those articles suggest that it gives mass to all particles (vector bosons + all fermions).
However, if I read a textbook I can only extract from the context that it gives mass only to the...
I've got another question before I can make my definitive decision:
If I decide not to end up in science and but instead in the industry (specifcially: finances or consulting), which college would be more beneficial for me?
Or as many graduates from ETH Zurich working in finance related jobs...
yeah, its ok, but its just the GCSE, you need to pay more attention when selection your A-Levels
Cosmology is more about the universe in general, i.e. solutions of Einstein's Field Equation (General Relativity), different phases of the universe (Big Bang to now), etc.
Astro-physics is more...
try to take as much mathematical and scientific subjects as possible (mathematics, physics, chemistry).
Latin is, arguably, also good for fostering logical thinking.
But in general, you can't do much wrong if you take mathematical and scientic subjects. But you should also include languages...
How important are the basics of mathematics for theoretical physics?
With basics of mathematics I mean knowing and be able to do proofs. Or is it enough if you know how to use this or that trick?
because I lack the knowledge of foundamental basics in mathematics and physics and because you need to do an undergraduate degree first before you can do a graduate degree
That's the problem, I really like both cities.
Zurich is very nice and really small, air is great and I live the food...
Hi guys and girls
I have the following problem:
I can't decide where I want to study physics (undergraduate).
I've got unconditional offers from Imperial College London for MSci Physics and Theoretical Physics and one from ETH Zurich for Mathematics/Physics (Bachelor/Master; ETH Zurich =...
If you want to study physics, you should consider the Technical University of Munich or the Ludwig-Maximilian University of Munich. Both are among the best German universities regarding physics and mathematics.
However, you can also consider the Federal Institute of Technology in Zurich (ETH...
Hi guys,
Everyone knows that one can calculate the S-Matrix with various tricks. One of them is to use traces to simplify the matrices.
Can someone tell me or point me to a place where I can find an explanation why I can do this?
I think I vaguely remember that I have seen once an...
I took it in December and got about 780 without any preparation (I'm in Austria). Just basic mechanics, electrodynmaics and electricity, nothing really difficult
I know German, English, Chinese, Spanisch and Latin, but I want to learn Arabic in the next couple of years. I don't have a specific reason, I just want to know that language, should be cool speaking and writing it
yep, exactly, that's what is described in the book
oh, IC now the reason of my wrong understanding. He uses \delta x_i because he wants to show explicitly that he's talking about separate cells (with the index i as one of the arguments of the field operator). On the page before that he...
Hi
I've got a question about a term in a formula I've found in Mandl&Shaw's QFT book
It's about equation 2.18 on page 31
L(t) = {\sum_i \delta \bf{x}_i {\cal L}_i \ ...
Why is there a delta x_i when summing over all lagrangians for getting the lagrange-function for the whole...
Does anybode know about a mailing list for Europeans (Austria)?
When looking for ordering the book, I get redirected to CERN publication request, but there it says it's out of print and there is no further indication of when the new edition is released
oh, I actually noticed, that I made a typo, the denominator is wrong
here is the right one:
\int_{\frac{3}{2}}^{2}(\frac{x-1}{3-x})^{\frac{1}{2}}dx
still recomending the same substitution?
Hi
Recently I found an integral which I can't solve, I don't know or can't guess how and what to substitute.
\int_{\frac{3}{2}}^{2}(\frac{x-1}{3-2})^{\frac{1}{2}}dx
Please tell me what you would substitute and why you would do that
Thanks
ps:
the solution isn't important to me...
Hi guys, do the LQG videos work for you all? Or do you have currently problems too?
it doesn't for me, after the information bar is displaying 'Transitioning' for a few seconds, it goes back to ready, meaning it stopped (play button available, pause and stop not)
edit:
just discovered...
Hi
Soon I'm finished with school and I have to decide at which university I want to study, but somehow I can't decide
I'm currently considering the following universities, can you please give any comments or maybe even experiences from yourselves or ones from friends you have heard...
thanks, but there's one thing i still don't understand
after substituting it in and then if you integrate, what happens to the term
\sqrt{\frac{\omega_p_'}{\omega_p}}
Magnetic fields do only exist if electric fields exist, hence both a existing at the same time and are the same wave (hence the word electromagnetic spectrum)
hm, are you saying all magnetic and electric fields consist of virtual photons and that only light consists of "real" photons?
yes...
Hi
Can someone please explain to me Eq 2.30 in Schroeder's and Peskin's book? (page 21)
how does he simplify the long equation of the commutator to this delta distribution?
\imath\delta^(^3^)\ (x - x')
Thanks
what about natural tribes and cultures?
In those cultures you rarely see anyone not obeying the leader's orders.
Murder and theft, for example, are only a "luxurios features" of our culture, in the so called modern world. You can find it very often in our world, you will rarely find it in...
Hi
A few days ago a interesting thought stroke me during my chemistry lesson.
I don't know how I started thinking about it, but i just thought that prokaryotes may not really be living organisms, but rather just a system of elements and molecules and a many many chemical/physical...
Actually I do want to know about QFT and all of the field theories (QED, electroweak, QCD), so I ordered Peskin's (should be arriving tomorrow, can't wait :!) )
Isn't Weinberg's really tough? that's what i have heard
Hi
Can anyone tell me the differences between normal light (waves of the EM spectrum, i.e. visible light, gamma ray, radio waves, etc.) and magnetic field?
I know that both, light and magnetic fields, consist of photons and i know that magnetic and electric fields are perpendicular to each...
Yes, it's for self-study, but my professor is helping me personally (I'm writing on a not yet specified subject a paper)
physics background, quantum mechanics (my most recent read book has been QM by Claude Cohen-Tannoudji
Do you think I can manage Peskin's book?
As I said, my...
Hi
I'm planning on studying quantum field theory, but I can't choose which book I should buy. I've heard great opinions of both, that's making my decision so hard
