PHY 4510
Thematic Melodies of 20th Century Theoretical Physics

Different topics illustrating important ideas in 20th century theoretical physics will be discussed. Topics covered will include: quantization, phase factor, path integral, symmetry, symmetry and groups in physics, modern developments and gauge theory. Prerequisite: permission of the instructor.

Theme

 

The true glory of physics in the 20th century lies in the deepened understandings of important primordial concepts which date from the beginning of human civilization: that of space, of time, of motion, of energy, and of force.  In all of these primordial concepts, there have been profound revolutions in our understanding, revolutions that had brought forth a more beautiful, more subtle, more precise and more unified description of nature.

 

There have been in recent years studies of many aspects of the detailed history of twentieth century physics.  It is not the purpose to delve into these subjects in this course.  What this course proposes to do is instead to look into this history for the broad motifs of the developments, and to trace the three main strands that had persistently woven through its conceptual advances, appearing again and again in a variety of forms, singly or intertwined, like the thematic melodies of symphonic music.

 

These three melodies together define the tone and the flavour of the main developments of physics in the 20th century:

 

·       Quantization

·       Phase Factor

·       Symmetry

 

Prerequisites

 

Although this course will be about some of the deepest ideas in 20th century theoretical physics, it is designed to be accessible to undergraduates. Students are expected to have taken the following courses (or equivalent) and learnt the subjects indicated.  All these are required courses for CUHK physics undergraduates, normally taken in the first term of year 2.
