Axons Process Information

I just heard about a very interesting new discovery in neuroscience:. The basic gist is that it appears that axons process information. Until now it has been thought that only the cell body of neurons was the part that processed information. Our present understanding of the brain, and also of psychopharmacology, is based completely on the dendrites and main body of the neuron. If it turns out that axons -- the "wires" that connect neurons -- are actually major contributors to how the brain computes, then it may point to both a new understanding of cognition, as well as a new frontier in treating mental and neurological disorders. (Thanks to Bram for letting me know).

Nova's Trip to Edge of Space

  • Stepsedgestratosphere
    In 1999 I flew to the edge of space with the Russian air force, with Space Adventures. I made it to an altitude of just under 100,000 feet and flew at Mach 3 in a Mig-25 piloted by one of Russia's best test-pilots. These pics were taken by Space Adventures from similar flights to mine. I didn't take digital stills -- I got the whole flight on digital video, which was featured on the Discovery Channel.

Nova & Friends, Training For Space...

  • Img021
    In 1999 I was invited to Russia as a guest of the Russian Space Agency to participate in zero-gravity training on an Ilyushin-76 parabolic flight training aircraft. It was really fun!!!! Among other people on that adventure were Peter Diamandis (founder of the X-Prize and Zero-G Corporation), Bijal Trivedi (a good friend of mine, science journalist), and "Lord British" (creator of the Ultima games). Here are some pictures from that trip...

People I Like

  • Peter F. Drucker
    Peter F. Drucker was my grandfather. He was one of my principal teachers and inspirations all my life. My many talks with him really got me interested in organizations and society. He had one of the most impressive minds I've ever encountered. He died in 2005 at age 95. Here is what I wrote about his death. His foundation is at http://www.pfdf.org/

He also builds carbon fiber trimarans in his spare time, and studies animal intelligence. He is working on several theories related to the origins of violence and ways to prevent it, new treatments for learning disabilities, and new theories of cognition. He doesn't have a Web site yet, but I'm working on him...
  • Marin Spivack
    Marin Spivack is my brother. He is the one of the only western 20th generation lineage holders of the original Chen Family Tai Chi tradition in China. He's been practicing Tai Chi for about 6 to 10 hours a day for the last 10 years and is now one of the best and most qualified Tai Chi teachers in America. He just returned from 3 years in China studying privately with a direct descendant of the original Chen family that created Tai Chi. The styles that he teaches are mainly secret and are not known or taught in the USA. One thing is for sure, this is not your grandmother's Tai Chi: This is serious combat Tai Chi -- the original, authentic Tai Chi, not the "new age" form that is taught in the USA -- it's intense, physically-demanding, fast, powerful and extremely deadly. If you are serious about Tai Chi and want to learn the authentic style and applications, the way it was meant to be, you should study with my brother. He's located in Boston these days but also travels when invited to teach master classes.
