What is Artificial Intelligence?

"It is the science and engineering of making intelligent machines, especially intelligent computer programs. It is related to the similar task of using computers to understand human intelligence, but AI does not have to confine itself to methods that are biologically observable."
- John McCarthy, 2007

Yes, but what is intelligence?

"Intelligence is the computational part of the ability to achieve goals in the world. Varying kinds and degrees of intelligence occur in people, many animals and some machines." - John McCarthy, 2007

Isn't there a solid definition of intelligence that doesn't depend on relating it to human intelligence?

"Not yet. The problem is that we cannot yet characterize in general what kinds of computational procedures we want to call intelligent. We understand some of the mechanisms of intelligence and not others." - John McCarthy, 2007

Blog 6: Computing Science & Mathematics

As we embark on reading the last textbook, it should be very obvious by now that mathematics is a core aspect of Computing Science. In fact, most Computing Science departments and disciplines have a direct foundation in the study of mathematics. Here’s a good quote summing it up from Harold Abelson: “Mathematics provides a framework for dealing precisely with notions of "what is". Computation provides a framework for dealing precisely with notions of "how to".” For this article, write about how Computing Science and Mathematics are related. (Food for thought - Read up on Theoretical Computer Science and Applied Mathematics). Things you can talk about:
