    Dang, wouldn't you know, I just found this page too. from the AIP

  2. Re:Not much information here... by Cy+Guy · · Score: 1 · on Single Molecule Memory

    According to my understanding of this diagram from Physics News, the "self-assembly" process involves tiny little elves with Santa Claus hats. They seem to drag a conductor over a gap in some sort of substrate.

    I'M NOT KIDDING! Take a look at the picture! However, this may only relate to his earlier work on molecular wires, but I assume, once you have figured out how to control the elves, the rest is rather straight forward.

    Well this inspired me to do a websearch. http://www.aip.org/enews/ physnews/1995/split/pnu244-3.htm http://www.sciam.com/ askexpert/geology/geology9/geology9.html The second references the first.

  5. There is no void by mvw · · Score: 3 · on Space Probes Too Slow - Scientists Ask "Why?"
    What you mean is a consequence of Heisenberg's uncertainty principle that holds too for the pair energy and time and Einsteins' equivalence of energy and matter.

    So while over long times the energy at a given empty volume in space is zero, for short times you are not sure. In fact for very short times it is unsure enough to allow the creation of virtual particles, like an electron positron pair, that "borrow" their energy from the vacuum, and annihilate after a short time, giving back the energy.

    Zero Point Energy

    Nope, that term describes the fact, that the lowest possible energy state for a harmonic oscillator in quantumn mechanics is non zero.

    The page is nice to read too, by the way.

    The article is a little short on facts. Here are a few more details:

    ABSTRACT:
    Unconditionally Secure Bit Commitment

    Adrian Kent
    Department of Applied Mathematics and Theoretical Physics, University of Cambridge, Silver Street, Cambridge CB3 9EW, United Kingdom

    (Received 13 July 1998)

    We describe a new classical bit commitment protocol based on cryptographic constraints imposed by special relativity. The protocol is unconditionally secure against classical or quantum attacks. It evades the no-go results of Mayers, Lo, and Chau by requiring from Alice a sequence of communications, including a postrevelation verification, each of which is guaranteed to be independent of its predecessor. ©1999 The American Physical Society
    Here are copies of his article in pdf and in gzipped PS.

  11. Curved surfaces, MEMS, etc... by Tekmage · · Score: 3 · on Paper-thin Integrated Circuits

    Personally, I prefer the ball semiconductor approach for microelectronics on curved surfaces. :-)

    Or for antenna-type structures, go for EFAB.

    ...and then there's that microphone reported a while back.
