In popular conception, mathematics is the ultimate resolvable discipline, immune to the epistemological murkiness that so bedevils other fields of knowledge in this relativistic age. Yet Philip Davis, emeritus professor of mathematics at Brown University, has pointed out recently that mathematics also is “a multi-semiotic enterprise” prone to ambiguity and definitional drift. Earlier this year,…
The main cost of starting a Web-based startup is food and rent. Which means it doesn’t cost much more to start a company than to be a total slacker. […] Most startups fail. It’s the nature of the business. But it’s not necessarily a mistake to try something that has a 90% chance of failing,…
I take the view that computer languages, robot ethics, method acting, and biomechanics are the main ingredients that fused, in the 1950s, to become the cultural meme we call Artificial Intelligence, or AI for short. None of those ingredients was wholly new at that time: biomechanics and the Method – first known as the Stanislavski…
He had discovered a great law of human action, without knowing it — namely, that in order to make a man or a boy covet a thing, it is only necessary to make the thing difficult to attain. If he had been a great and wise philosopher, like the writer of this book, he would…
Professors see the world in terms of experts and students: “We are smart; you are dumb.” That’s the Infantile American Principle in a nutshell. Now go play with your toys and don’t bother me. —David Gelernter —The ‘We’re Smart, You’re Dumb’ Principle (LA Times (will expire)) The article is really a critique of Democratic philosophy, but…
Telling ourselves we have “so much” to do and that it is “so hard” and that we’ll “never get done” is conterproductive. Instead of talking about these things we should just haul off and do them! And don’t let friends that don’t get this concept to drag you down with them. Let them list their…
Professors, in general, have the luxury of appearing moderate and open to competing ideas, but insecure students often research the opinions of faculty members to ensure that they will be on the correct side of any apparently open dialogue. The powerless seize on small expressions of political opinion from the powerful and embrace these views…
“Their parents posted ‘Baby on Board’ signs in their cars. They have been protected as children. Their free time was replaced by organized activities and structured programs. They have a high need for achievement and attention,” said Xavier spokeswoman Kelly Leon. She said this generation prefers learning from hands-on experience, craves technology-generated education, and feels…
Every grader of blue books was once a writer of blue books, so it might help to think about the process from that end. I remember, with particular shame, a certain undergraduate essay exam of my own for a course in “Modern Moral Philosophy.” The professor was Philippa Foot, who must have been in her…
Now, in a breakthrough described as the classical equivalent of finding the holy grail, Oxford University scientists have employed infra-red technology to open up the hoard, known as the Oxyrhynchus Papyri, and with it the prospect that hundreds of lost Greek comedies, tragedies and epic poems will soon be revealed. In the past four days…
Mistake: A student raises her hand to announce that there’s a typo on a handout. Knee-Jerk Reaction: Saying “I did that on purpose just to see if you guys were paying attention.” Constructive Response: Reward the student who discovered the typo. Ask the whole class to correct the error on the handout by hand. Then…

Society is commonly too cheap. We meet at very short intervals, not having had time to acquire any new value for each other. We meet at meals three times a day, and give each other a new taste of that old musty cheese that we are. We have had to agree on a certain set…
To many guardians of the knowledge cathedral – librarians, lexicographers, academics – that’s precisely the problem. Who died and made this guy professor? No pedigreed scholars scrutinize his work. No research assistants check his facts. Should we trust an encyclopedia that allows anyone with a pulse and a mousepad to opine about Jackson Pollock’s place…
For the uninitiated, FUD stands for ?Fear, Uncertainty, and Doubt.? It is a term popular within the free software community, used to describe the use of lies and deceptive rhetoric, aimed chiefly at free software projects. It is an accurate term. In brief, the goal of FUD is to make money when the free software…
Paradox though it may seem–and paradoxes are always dangerous things –it is none the less true that Life imitates art far more than Art imitates life. We have all seen in our own day in England how a certain curious and fascinating type of beauty, invented and emphasised by two imaginative painters, has so influenced…
The “Third Bridge” is the nanotechnology and artificial intelligence revolution, which Kurzweil predicts will deliver the nanobots that work like repaving crews in our bloodstreams and brains. These intelligent machines will destroy disease, rebuild organs and obliterate known limits on human intelligence, he believes. Immortality would leave little standing in current society, in which the…
I was talking about Wikipedia, and he launched into a rant about its failings. In particular, he complained about the several inaccuracies in an article about a topic with which he was deeply familiar. “So,” I asked, “did you fix them?” “No,” he responded, “I don’t have time for that kind of thing.” Talk about…
What is Tenure? (The Good Morning Show — KFAB) This morning at about 8:40, I spent about 12 minutes as a telephone guest on a morning talk show on KFAB in Nebraska, where I was brought in to provide context for the Ward Churchill controversy at the University of Colorado. My role was to explain tenure.…
I used to love routines, particularly the way they allowed life’s more mundane aspects to slip into the background, removed from conscious decision making. Before becoming a dad, my mornings began with a predictable sequence. Coffee. Bagels. NPR. But with a newborn, routines are constantly at risk. You put your hand to her little forehead.…
