I was very pleased to be asked to produce a fifth edition of our artificial intelligence book. It is
a compliment to the earlier editions, started almost twenty years ago, that our approach to AI …

Abstract Objects move, collide, flow, bend, heat up, cool down, stretch, compress, and boil.
These and other things that cause changes in objects over time are intuitively characterized …

This article addresses the problem of understanding mathematics described in natural
language. Research in this area dates back to early 1960s. Several systems have so far …

Everyday life provides people with countless opportunities for observing and interacting with
objects in motion. For example, watching a baseball game, driving a car and even dropping …

Inasmuch as people are good at predicting the outcome of physical interactions in the world
around them, why are they so bad at physics, even the branch of physics (mechanics) that …

Introduces the basic concepts of robot manipulation--the fundamental kinematic and
dynamic analysis of manipulator arms, and the key techniques for trajectory control and …

A qualitative physics predicts and explains the behavior of mechanisms in qualitative terms.
The goals for the qualitative physics are (1) to be far simpler than the classical physics and …

To endow computers with common sense is one of the major long-term goals of artificial
intelligence research. One approach to this problem is to formalize commonsense reasoning …

Developers of intelligent tutoring systems would like to know what human tutors do and
which activities are responsible for their success in tutoring. We address these questions by …
