Author: David McIntyre
This innovative new text presents quantum mechanics in a manner that directly reflects the methods used in modern physics research―making the material more approachable and preparing students more thoroughly for real research. Most texts in this area start with a bit of history and then move directly to wave-particle problems with accompanying heavy mathematical analysis; Quantum Mechanics provides a foundation in experimental phenomena and uses a more approachable, less intimidating, more powerful mathematical matrix model. Beginning with the Stern-Gerlach experiments and the discussion of spin measurements, and using bra-ket notation, the authors introduce an important notational system that is used throughout quantum mechanics. This non-traditional presentation is designed to enhance students’ understanding and strengthen their intuitive grasp of the subject.
