Modern theoretical physics has made enormous progress, which may well be compared to the dramatic developments that occurred during the first few decades of this century.The search for a common origin of all interactions is an ultimate goal of physics. A comparable brekthrough occurred twenty years ago when Glashow, Salam, Weinberg, and others recognized a deep relation between the electromagnetic and the weak nucleat interaction and showed that they could be derived from a unified theory. These lectures make an attempt to familiarize the student with the development of modern particle physics by providing a conceptually simple, yet rigorous introduction combined with hands-on experience through exercises and examples. 本产品为英文版。
