Victim of the Brain A 'docudrama' about Godel, Escher and Bach author, Douglas Hofstadter, and philosopher Dan Dennett produced in 1988. I'm not sure how to describe it, other than incredibly strange and fascinating.

Dr James Anderson, from the University of Reading's computer science department, claims to have defined what it means to divide by zero. It's so simple, he claims, that he's even taught it to high school students [via Digg]. You just have to work with a new number he calls Nullity (RealPlayer video). According to Anderson's site The Book of Paragon, the creation, innovation, or discovery of nullity is a step toward describing a "perspective simplex, or perspex [ . . . ] a simple physical thing that is both a mind and a body." Anderson claims that Nullity permits the definition of transreal arithmetic (pdf), a "total arithmetic . . . with no arithmetical exceptions," thus removing what the fictional dialogue No Zombies, Only Feelies? identifies as the "homunculus problem" in mathematics: the need for human intervention to sort out "corner cases" which are not defined.

The Ethics of Deep Self-Modification. What will happen when machines gain the ability to modify their own psychology? Do we have a responsibility to step in? What happens when we have the ability to modify ourselves? Philosopher Peter Suber has dedicated himself to issues of self-modification... not just in psychology, but also in constitutional law. Small wonder that this is the guy who invented Nomic. His site is littered with great stuff; he now is primarily involved with the open access movement. Check out his open access primer and blog.

Another year, another Chat. This year's Loebner Prize competition will be held next week in Atlanta, GA (at SciTrek and GSU). The yearly contest is a modified "Turing test" (seminal paper here) where people try to guess whether they're chatting with computers or with people.

There are some resources for rolling your own AI bot, but before you begin, think about these two sentences and you'll see what a serious problem natural language is: "We gave the monkeys the bananas because they were hungry" and "We gave the monkeys the bananas because they were ripe" (nod to this guy for the example). You have to know a lot about the world and the things in it to disambiguate the "they" in those sentences.
