    An early look at artificial Intelligence. Guests includes Edward Feigenbaum of Stanford University, Nils Nilsson of the AI Center at SRI International, Tom Kehler of Intellegenetics, Herb Lechner of SRI, and John McCarthy of Stanford. Featured demonstrations include Inferential Knowledge Engineering and the programming language LISP. Originally broadcast in 1984.

    Q. What is artificial intelligence?

    A. 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.

    Q. Yes, but what is intelligence?

    A. 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.

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

    A. 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.

    Q. Is intelligence a single thing so that one can ask a yes or no question “Is this machine intelligent or not?”?

    A. No. Intelligence involves mechanisms, and AI research has discovered how to make computers carry out some of them and not others. If doing a task requires only mechanisms that are well understood today, computer programs can give very impressive performances on these tasks. Such programs should be considered “somewhat intelligent”.

    Q. Isn’t AI about simulating human intelligence?

    A. Sometimes but not always or even usually. On the one hand, we can learn something about how to make machines solve problems by observing other people or just by observing our own methods. On the other hand, most work in AI involves studying the problems the world presents to intelligence rather than studying people or animals. AI researchers are free to use methods that are not observed in people or that involve much more computing than people can do.

    Q. What about IQ? Do computer programs have IQs?

    A. No. IQ is based on the rates at which intelligence develops in children. It is the ratio of the age at which a child normally makes a certain score to the child’s age. The scale is extended to adults in a suitable way. IQ correlates well with various measures of success or failure in life, but making computers that can score high on IQ tests would be weakly correlated with their usefulness. For example, the ability of a child to repeat back a long sequence of digits correlates well with other intellectual abilities, perhaps because it measures how much information the child can compute with at once. However, “digit span” is trivial for even extremely limited computers.

    Hosted by Stewart Cheifet, Computer Chronicles was the world’s most popular television program on personal technology during the height of the personal computer revolution. It was broadcast for twenty years from 1983 – 2002. The program was seen on more than 300 television stations in the United States and in over 100 countries worldwide, with translations into French, Spanish, Chinese, and Arabic. The series had a weekly television broadcast audience of over two million viewers.

    Many of the series programs are distributed on video to corporations and educational institutions for use in computer training. Computer Chronicles program segments have also been bundled with various computer text books by major publishers.

    Convection is one of those words that we often hear used, but we may not completely understand its meaning. Weather forecasters show how convection currents are formed when warm and cold air masses meet in the atmosphere. Convection currents are responsible for warm water currents that occur in oceans. This activity demonstrates convection currents in a very colorful fashion.

    Anti-Gravity Water – Sick Science! #073

    Water in rivers, in a glass, or falling from clouds obeys gravity. It’s going to fall towards the ground because of the physical pull of the earth. But, what if we told you that you could turn a glass of water completely upside down and the water wouldn’t fall to the floor? That’s what happens in the Anti-Gravity Water demonstration. It’s a simple experiment that dramatically demonstrates the amazing physical properties of water.
