At my physics faculty there is this magazine that comes out once every three months. I wrote an article about GR for it. Introducing not only the concepts but also some mathematics. I explained the field equations and derived some implications of the Schwarzschild metric. I could do this because I read some books about it in the summer.(adsbygoogle = window.adsbygoogle || []).push({});

Now I'm supposed to write a similar piece, so with mathematical backup, about QFT. But as a third year (applied-)physics student I have not encountered the subject in class. And I actually found the books I opened about it quite intimidating.

I will try to read a book about it, because what I've seen about it it seems like a very interesting subject. But I would like to know if (you think) it is possible to give a comprehensive outline of the ideas not only in words to an audience of physics students from sophomores to graduates. Not everybody has to understand everything. But I would like those who had an introductory course in QM, SR, and have seen the EL en Hamiltonian formalism to grasp the ideas; including myself! And I would like to show some of the good stuff from QFT, to enthousiasm the readers.

I would also like to know what aspects of the theory are not too difficult and interesting. Like is it very difficult to derive the Casimir force between two parallel plates? I already found out deriving the KG equation is easy and the Dirac equation is also doable. So I would like to start with that. But what other subjects are interesting and can be explained in an article of lets say 3000 words?

And are there any good sites about QFT. I already found Wikipedia had a lot of interesting articles.
