Lecture Notes on Special Relativity - Macquarie University

Chapter 1 Introduction: What is Relativity? U the end of the 19th century it was believed that Newton’s three Laws of Motion and the associated ideas about the properties of space and time provided a basis on which the motion of matter could be completely understood.

Particle Spin and the Stern-Gerlach Experiment

Chapter 6 Particle Spin and the Stern-Gerlach Experiment The spin of an elementary particle would appear, on the surface, to be little different from the spin of a macroscopic object – the image of a microscopic sphere spinning around some axis

Observables and Measurements in Quantum Mechanics

haustive collection of results obtained when measuring some physical property, or observable, of the system. This linking of particular states with particular measured results provides a way that the observable properties of a quantum system can be described in quantum mechanics, that is in terms of Hermitean operators.

The Wave Function - Macquarie University

The wave function or wave packet so constructed is found to have essentially zero ampli- tude everywhere except for a single localized region in space, over a region of width 2∆ x , i.e. the wave function Ψ( x , t ) in this case takes the form of a single wave packet, see Fig. (3.3).

Introductory Quantum Chemistry Chem 570a: Lecture Notes

2 The Fundamental Postulates of Quantum Mechanics Quantum Mechanics can be formulated in terms of a few postulates (i.e., theoretical principles based on experimental observations). The goal of this section is to introduce such principles, to-gether with some mathematical concepts that are necessary for that purpose. To keep the notation

Classical Mechanics: a Critical Introduction

Theory of Relativity. Both quantum mechanics and relativity were invented in the twentieth century; the laws of classical mechanics were stated by Sir Isaac Newton in 1687[New02]. The laws of classical mechanics enable us to calculate the trajectories of baseballs and bullets, space vehicles (during the time when the rocket
