Item description for A Story Of Light: A Short Introduction To Quantum Field Theory Of Quarks And Leptons by M. Y. Han...
This book presents the essential aspects of relativistic quantum field theory, with minimal use of mathematics. It covers the development of quantum field theory from the original quantization of electromagnetic field to the gauge field theory of interactions among quarks and leptons. Aimed at both scientists and non-specialists, it requires only some rudimentary knowledge of the Lagrangian and Hamiltonian formulation of Newtonian mechanics and a basic understanding of the special theory of relativity and quantum mechanics.

Elegant description of QFT and fundamental issues. Jun 7, 2005
If you are an aficionado of popular physics and want to peer behind the curtains to see where some possible weaknesses have been swept under the rug, this is an excellent book. M.Y. Han has written an elegantly terse (107 pages) book which describes how Quantum Field Theory has evolved and been applied to Electrodynamics, the Weak Nuclear and Strong Nuclear force. To fully appreciate the book requires more education than a mere B.S. in physics which is the way the marketing description reads. Nonetheless, if you are an avid reader of Brian Greene, Steven Weinberg, and Gordon Kane, you will get a lot out of this little tome.
Han shows how in the case of Quantum Electrodynamics that Quantum Field Theory has worked spectacularly well. Because of this, QFT has been extended and emulated to explain the Weak and Strong nuclear interactions despite little problems such as the lack of renormalization in the case of the Strong Force and the massive bosons in the case of the Weak Force. The title, "A Story of Light" alludes to the fact that QED has shown the way for the other forces of the Standard Model.
Han raises the question whether this emulation is valid. For example, just because quantization of the electromagnetic field leads to photons, is it valid for all matter fields to be considered quanta of their own quantized field? Or is it valid to apply the "substitution rule" from classical electrodynamics to non-electrodynamic interactions? Just because QED happens to obey a gauge symmetry law, is it valid to raise that to a principle of physics and apply it to the Weak and Strong forces?
The book might reach a broader audience if a few more pages were devoted to explaining mathematical preliminaries such as special unitary groups and tensor representations of electromagnetic laws. I bet that this would be a useful book to graduate students who want to clearly understand the big QFT picture before diving into the details.
