Stephen Wolfram Radio Lecture

Stephen Wolfram, subject of much discussion here, once known solely as the creator of Mathematica, now also known as the author of A New Kind of Science (/. review here), gave a lecture at Boston University this past spring on that book's subject matter. The audio of the lecture was broadcast this evening on the program World of Ideas on WBUR-FM out of Boston. If you don't live in the Boston area, if you missed the program, or if like me you were listening in your car while driving and found that two activites incompatible, the hour-long recording is also available for download in RealMedia format.

  7. Wrapper? by LudditeMind · · Score: 1

    Can someone explain to me how he decides how many columns to have? Sure cellular automata makes pretty patterns, but is the grid arbitrary?

    1. Re:Wrapper? by Dachannien · · Score: 1

      Depending on the rules used to drive the CA, the number of columns could have an effect anywhere between no effect at all, or an effect dependent upon the value modulo some number which is dependent upon the rules.

      In other words, some systems might not be affected by the number of columns at all (for instance, those where the boundaries of the affected CA cells don't expand - these are typically degenerate cases anyway. But another system might produce different behavior if it has 4n columns versus 4n+1, 4n+2, or 4n+3.

      Ultimately, he should examine lots of different numbers of columns, at least up to the point where the behavior repeats qualitatively, thus determining the k in kn, kn+1, kn+2, ... , kn+(k-1).

    2. Re:Wrapper? by asterisk_man · · Score: 2, Insightful

      My understanding from reading the book and looking at all of the images he includes is that the number of columns is essentially infinite but for obvious reasons only a finite number of columns can be shown at any one time. In the book you will notice that he will show a zoomed in image of a CA with maybe 25 columns and 25 iterations but the zoomed out version of that CA with 100 iterations is shown with 100 columns. Sometimes he also seems to show just a vertical slice of the real CA in order to demonstrate its properties but I have a pretty strong feeling that the image width was not the same as the simulation width.
      Make any sense?

    ...at least in this case, I wouldn't say anything is 'out of reach' -- the gems of wisdom imparted in the lecture are available in his 6,000 page book that covers the subject. (ok, maybe 1,200 pages but you get the picture). If you're not familiar with the material, you can get a lot more from reading a critique of the book. If you are familiar, you pretty much sit there and wonder whatever made you think *you* were so smart.

    There is a lot of relevant content on a number of his websites...he kept telling us to read and re-read different sections of the book.

    I saw this lecture in Chicago, and it's not unlike walking off the street into a 400-level physics course. A brilliant professor walks in and immediately gets started, armed with a few powerpoint slides and ultradry jokes, he steamrolls through the first 300 pages of his book in 60 minutes. An audio stream of this isn't going to make or break your understanding on the subject.

    This stuff is like 40 years old. Older than Unix (30 year old OSes are fine, 31 year old ones well...).

    I used to create two colonies of cells which after a certain modification would start firing moving structures at each other destroying each others sections. Sometimes bridges were built. I had one where cells seemed to patrol the border like a marquee (in reality they weren't moving, the cells simply progressed in the same decaying states). For the majority of situations, these patrols prevented incoming bodies from destroying the structures they were seemingly protecting.

    We don't need a new kind of science. We need a level playing field that allows anyone to research without the kind of elitism that infuriates just the kind of people that cause independent groups to degenerate into cliques and feuds often found in the Free Energy, Cold Fusion, and Perpetual Machine cults.

    We need a new approach at problem solving. Running a hundred experiments that make no new predictions is not science. Show me a laptop powered by water and I'll drop a dime into the donation cup.

    If anything this stuff simply says that when things change they may stay the same. We program using code that behaves the same way at all times.
    Suppose code frangments changed in ways that valid execution strings were still created, but rather than taking up many gigs of space you would call a timer to capture a certain snapshot and rearrange the code to perform some other work.

      I don't mean to be disrepectful, but if you're only saying that "life.c" was written a long time ago you should read some reviews of this book. Even a cursory glance at the reader commentary on Amazon will show that Wolfram is not trying to say that cellular automata are neeto. He spent ten years on this thing with the intention of showing that (roughly) Nature is a cellular automaton. I think his desire is to point the way to a kind of Grand Unified Theory -- except instead of finding a simple formula beneath it all the way e=mc^2 summed up Relativity he would have us search for an algorithm that spawns the universe. My take on this could be all wet (and so could he), but he is too intellectually aware, ambitious, and arrogant to merely add an appendix to an old chapter in computer science.

      You should read the book. You missed the point more or less totally. Actually first read Godel (esp. Incompleteness Theorem), then Turing (Halting Problem/Turing machines). Then look up Solomonoff, Kolmogorov, and Chaitin (Algorithmic Information Theory). Then you'll be at least in a position to have half a clue of where Wolfram is coming from and why the progress of mathematics will/does require an experimental approach (Chaitin is the man leading that school of thought). You'll also find that your last comment would be regarded as "been there, done that" by many great minds before yours.
