Is Quantum Field Theory Always This Challenging?

[dimachka]

I'm not sure if this is the correct forum but i figured I would post here. So I've been working on a problem set for my first quantum field theory class consisting of 3 problems since 10am this morning with nothing but a few 20 minute breaks to eat, i just finished the second problem after 17 hours and 20 minutes. I'm just wondering if this is something unique to the beginnings of quantum field theory (i.e. before we have started path integral formulation, we are still doing chapters 5 and 6 of P&S) or if this is what I have to look forward to for all my studies of QFT? Thanks in advance for any comments.

Thank you for sharing your experience with us. I can understand the frustration and exhaustion you must be feeling after spending such a long time on just two problems. Quantum field theory is a complex subject and it is not uncommon for students to struggle with it in the beginning.

I would say that the time taken to solve problems in QFT can vary depending on the individual's understanding and background in the subject. Some may find it easier and quicker to solve problems, while others may take longer. It also depends on the complexity of the problems and the methods used to solve them.

However, I would like to assure you that with practice and a deeper understanding of the subject, you will become more efficient in solving problems in QFT. As you progress further in your studies, you will also learn new techniques and approaches that will make problem-solving easier and faster.

So, I would say that this is not something unique to the beginning of QFT, but rather a part of the learning process. It is important to take breaks and not push yourself too hard, as it can lead to burnout. Remember to pace yourself and seek help from your professors or peers if needed.

I wish you all the best in your studies of QFT and hope that you continue to challenge yourself and learn more about this fascinating subject.
