**The Schrodinger equation**

This course aims to present the basics of quantum mechanics in an easily understandable way.

Thus the course will answer the following kinds of questions: What do we mean by saying the electron is a wave? In what sense is it a particle? Is physics fundamentally predictable or random? What is the puzzle of the Schrodinger cat, and what is its resolution?

We will also look at a few applications of quantum mechanics, like lasers and quantum computers.

While many presentations focus on the history of the subject, we will focus on what the theory *is*. Thus at the end of this course the reader should understand the fundamental ideas of quantum theory the same way that a professional physicist would.

The ideas are presented through text supported by graphic illustrations. There are very few equations, and those that are cited are both elementary and basic to the subject.
