This book is the fruit of for many years teaching the introduction to quan-tum mechanics to second-year students of physics at Oxford University. We have tried to convey to students that it is the use of probability amplitudes rather than probabilities that makes quantum mechanics the extraordinary

That theory is known as quantum mechanics, and it is now the basic framework for understanding atomic, nuclear, and subnuclear physics, as well as condensed-matter (or ”solid-state”) physics.
This book introduces the most important aspects of quantum mechanics in the simplest way possible, but challenging aspects which are essential for a meaningful understanding have not been evaded.
The postulates of quantum mechanics. 1.9 States and wavefunctions. 1.10 The fundamental prescription. 1.11 The outcome of measurements. 1.12 The interpretation of the wavefunction. 1.13 The equation for the wavefunction. 1.14 The separation of the Schro ̈dinger equation. The specification and evolution of states. 1.15 Simultaneous observables.
This chapter gives a brief introduction to quantum mechanics. Quantum mechanics can be thought of roughly as the study of physics on very small length scales, although there are also certain macroscopic systems it directly applies to.
Introduction to Quantum Mechanics Quantum mechanics is a sub eld of physics that studies how th e universe works at atomic and subatomic levels. It is an essential part of und ergraduate and graduate courses in physics and undergraduate engineering courses in India. This book comes from the desk of authors who have decades of grad uate-level
There is a huge number of excellent and comprehensive textbooks on quantum mechanics. They mainly differ for the approach, more or less oriented to the formalism rather than to the phe-
