Last November I delivered a lecture on complex-system economics at a world-famous institute in Santa Fe, New Mexico. I also attended a conference on science education in the same city, along with a physicist from Turkey who was visiting there at the time.

The conference, aimed at improving mathematics and physics education in the United States, was organized by David Pines, co-director of the Institute for Complex Adaptive Matters, and attended by university and high-school teachers, writers, directors of science movies, computer engineers and many others. The subject was how to prepare a teaching program on superconductivity for junior- and high-school students.

I spoke of my experience as the author of a math textbook, "Let's Study Math" (not approved by Japanese censors). The idea behind the book -- providing children with a text for self-study -- received a favorable response from the audience.
