Quantum Mechanics: Volume 3: Lectures on Theoretical Physics

by David Tong

The universe we live in is both strange and interesting. This strangeness comes about because, at the most fundamental level, the universe is governed by the laws of quantum mechanics. This is the most spectacularly accurate and powerful theory ever devised, one that has given us insights into many aspects of the world, from the structure of matter to the meaning of information. This textbook provides a comprehensive account of all things quantum. It starts by introducing the wavefunction and its interpretation as an ephemeral wave of complex probability, before delving into the mathematical formalism of quantum mechanics and exploring its diverse applications, from atomic physics and scattering, to quantum computing. Designed to be accessible, this volume is suitable for both students and researchers, beginning with the basics before progressing to more advanced topics.

About the author

David Tong is your average Malaysian guy - down-to-earth and handsome. Bread and buttered at the King George Vth. School, Seremban after the WWII, he was thereafter trained as a teacher at the Kirkby College in Liverpool, England. In addition to a number of years as a teacher of English as a second language, his background encompasses sales and marketing, and general and agency management.

Now retired, David spends most of his senior years laughing over both old and new jokes, believing that laughter is certainly good medicine for his bones. When he is not laughing in his sarung at his home in Kuala Lumpur, David can be found sipping teh tarik at his favorite mamak stall, making quirky remarks and spinning frivolous kopitiam years with his cronies.
