Welcome to Discrete Mathematics, a subject that is off the beaten track that most of us followed in school but that has vital applications in computer science, cryptography, engineering, and problem solving of all types.
Most of the mathematics taught after elementary school is aimed at preparing students for one subject—calculus, which is the mathematics of how things grow and change continuously, like waves in the water or clouds in the sky. Discrete mathematics, on the other hand, deals with quantities that can be broken into neat little pieces, like pixels on a computer screen, the letters or numbers in a password, or directions on how to drive from one place to another.

It's as essential to human existence as water is to a fish, and yet every night we surrender it gratefully. As human beings, we recognize that we have it, but we can never be sure anyone else does. It has been the subject of debate for philosophers and scientists for millennia, but we've yet to pin down or even understand its true essence and purpose.

It's consciousness, and if you think you grasp the nuances of this unique mental state, then take a moment to consider ... the zombie.

Most of us are familiar with this wretched star of B-grade horror films: a once-human creature dead but not truly dead. In its state of suspended life, it performs many of the tasks we do every day. It can move, it can carry things, it finds its way around. In some movies, it even seems motivated by a purpose—the inexorable quest for living flesh.
