Via Instapundit: A link to an interview with Max Tegmark in Discover Magazine, one of my favorite living scientists (he produces a lot of interesting work outside his own specialism of cosmology).
The interview by Adam Frank, an astrophysicist at the University of Rochester in New York, is titled "Is the Universe Actually Made of Math?" and covers Tegmark's thinking on the mathematical nature of the universe. It's a useful companion piece to his paper "The Mathematical Universe" which I referred to briefly back in February.
If you're interested in wacky ideas, Tegmark's your man.
