    Isn't it funny how new knowledge breaks constraints that seem like fundamental limits? [a] laser can’t read the information encoded in the disc’s pitted surface if the pits measure less than half the wavelength of the light, thus constraining the amount of data that can be stored on the disc. Now two teams of researchers have harnessed a core property of quantum physics called entanglement to link photons together, overcoming this so-called diffraction limit. http://www.sciam.com/article.cfm?chanID=sa003&articleID=0009A807-8FAB-10A2-8FAB83414B7F0000[^] ----------------------------------------------------- Bush To Iraqi Militants: 'Please Stop Bringing It On' - The Onion

      I can't post it here, as it's copyrighted code, but it looked like this: http://www.regexlib.com/REDetails.aspx?regexp_id=390[^] Then, I commented it out and broke it in several lines and now it's 80 lines big, but still hard to understand... Due to technical difficulties my previous signature, "I see dumb people" will be off until further notice. Too many people were thinking I was talking about them... :sigh:

        Isn't it funny how new knowledge breaks constraints that seem like fundamental limits? Or application of old knowledge. The concept of entanglement has been known for nearly as long as the uncertainty principle. We have finally started to embrace it. The uncertainty principle still applies, as a relationship between momentum and position. They have just found a way to increase the momentum by creating an entangled quasi-particle rather then increasing the wavelength of the light.

            dude, you gotta get off that stuff, I heard regular expressions cause cancer. I know of a good support group if you really wanna quit. Remember, the first step to quitting is realizing you have a problem. Don't worry bro, we're here for you. ~Nitron.

                    Luck to you! Nothing sounds "regular" about that expression... I'd be willing to put money on the chance that the person who wrote it had more than a brush or two with PERL :-D Syntactic sugar causes cancer of the semicolon. ~ Alan Perlis

                      Ah...TECO, now that was a GREAT editor....I even did a port to a Motorola 6809 system in the mid 1980s - editor took about 20KB which left me with about 11KB for the text and macro buffers... Steve

"...With respect to Mystery, everything we behold is, in one sense, a mystery to us. Our own existence is a mystery: the whole vegetable world is a mystery. We cannot account how it is that an acorn, when put into the ground, is made to develop itself and become an oak. We know not how it is that the seed we sow unfolds and multiplies itself, and returns to us such an abundant interest for so small a capital. The fact however, as distinct from the operating cause, is not a mystery, because we see it; and we know also the means we are to use, which is no other than putting the seed in the ground. We know, therefore, as much as is necessary for us to know; and that part of the operation that we do not know, and which if we did, we could not perform, the Creator takes upon himself and performs it for us. We are, therefore, better off than if we had been let into the secret, and left to do it for ourselves...." http://www.infidels.org/library/historical/thomas_paine/age_of_reason/part1.htm[^] Later, JoeSox "Without purpose there is no existence." -- Mr. Smith, Matrix Reloaded joeswammi.com ↔ humanaiproject.org ↔ joeswammi.com/sinfest
