Introduction to quantum mechanics

Introduction

Quantum Mechanics is a theory in physics which primarily tries to explain how extremely small bodies, such as atoms, behave. Scientists generally agree that it is a very accurate and successful theory and it has very important applications in today's world as all electronic devices, such as computer chips, depend on Quantum Mechanics is some way. It is also important in understanding how large objects such as stars and the Universe as a whole are the way they are.

Despite how successful Quantum Mechanics is at explaining what we see, it does it does have some controversial elements. For example, the behaviour of microscopic objects is very different from the behaviour of everyday objects, and some of its results appear to contradict the Theory of Relativity.
