    We will begin by introducing the tools from quantum mechanics that we will need to describe electrons. We will introduce probabilistic descriptions of the key physical properties: position, momentum, time and energy. In the next part we will consider electrons in the simplest possible model of a conductor – a box – i.e. we will ignore atoms and assume that the material is perfectly homogeneous. This model of electrons in conductors is known as "the particle in a box‟. It is surprisingly useful, and later in the class we will employ it to describe the behavior of modern transistors.
