Thank you so much Prof. Tobias Osborne. I have been searching for a good set of lectures on QFT for a while, and here I am finally discovered what I have been looking for. And thank you Alexander St. John for spending your time transcribing the lectures, it helped me a lot.
Tobias, a general question about how to engage in independent study of physics (my background is that I have BSc in physics but have no formal training beyond that) : do you think I can safely assume that any book published by a reputable company such as Springer, CRC or any of the ubiquitous University Presses will be providing accurate and correct contect? my main concern is that I might pick up a book that will espouse incorrect physics and/or offer unhelpful ways of understanding or interpreting a phenomenon
Sorry for my late reply! I do think that basically any book from Springer/CUP/AW etc. can be trusted. I used to worry about getting the "best" book so as not to learn the "wrong thing". However, after a couple of years I learnt that there really are only small differences in points of view/formalism etc. between books and the danger of encountering incorrect physics is very low (by reading several sources you can easily correct for such errors -- repetition coding is very efficient). As you learn more you will develop your own opinions anyway and become much more selective. Best wishes! sincerely, Tobias
Hi Dr. Osborne, I am a particle physics graduate student organizing a study group with some fellow students for advanced QFT. We would like to use your lectures, and I was wondering if there is there any way that I can access the problem sets that you assigned for this class? Thank you, Mitch
many thanks for your comment: I am happy to hear you are interested in my videos. Unfortunately the problem sheets are not available for the course (I did not run the exercise class). However, you can get a good idea of the what the exercises were by following the lectures and attempting the exercises I set along the way. I hope this helps. Sincerely, Tobias Osborne
Dear Prof Osborne, Is there any way to get hold of the corresponding assignments following the your courses on Advanced Quantum Mechanics, Quantum Field Theory and Advanced Quantum Field Theory? It would be of great help along with your mode of instruction that we can obtain from your lecture videos. Please keep up the great work. And can't wait for the lectures on symplectic geometry and classical mechanics.
Dear Sumit Dey, The assignments will not be released. However, you can get a good idea of what is on them by simply solving all the exercises I mention in the lectures. Sincerely, Tobias
I'm wondering about the rigorous results alluded to in the video. For one, does the statement "you can construct the path integral rigorously and use it to quantize classical systems only if you know the answer already" point to the rigorous construction of path integral measures in certain special cases (even for interacting quantum fields)? Are there and good materials for the mathematical background of this? Also I can't find any decent overview of the Duistermaat-Heckman stuff. Does someone know a good reference? (I assume that's very much related for the classical mechanics course going on now)
I am alluding to constructive quantum field theory. An excellent reference is "Quantum Physics: A Functional Integral Point of View" by Glimm and Jaffe. The original paper of Duistermaat-Heckman is still the best discussion in my opinion: link.springer.com/article/10.1007%2FBF01399506 .
Dear Rooney Styles, I would love to make videos of those topics but I will not be teaching them this or next semester (the next subject to come will be on symplectic geometry and classical mechanics). Also I am really not an expert on string theory/quantum gravity... Sincerely, Tobias

Dear Prof Osborne,
Are there written notes for these lectures?
Thank you.
thank you very much. You are our professor indeed!!!
Greatly appreciated your remarks at the end of the video.
is this course on QCD ?

Why is the position eigenbasis not really a proper basis at all?

awsome! hope that u will upload the whole modul
Dear Christian,
I do plan to upload the whole course, unless of course there are technical problems.

Where can I find the problem set of the course? Thanks in advance!
see reply to Sumit Dey below.
Hi, I wonder whether there are the lecture notes of the video?
Dear Dongming He,
At the moment not. I would recommend reading the corresponding chapters of Peskin and Schroeder.
Sincerely,
Tobias Osborne
String theory And Quantum Gravity.....Plzzzzz make videos of these
Dear Rooney Styles,
I would love to make videos of those topics but I will not be teaching them this or next semester (the next subject to come will be on symplectic geometry and classical mechanics). Also I am really not an expert on string theory/quantum gravity...

thanks!
ok Plzzzzz then Classical Mechanic......is okkk and thx for ur support
strings no please is not physics
