  • Scientists create unbreakable code to stop hackers

    I think you hit the nail on the head.


    I found this little bit of information on entwining.
    When a photon (usually polarized laser light) passes through matter, it will be absorbed by an electron. Eventually, and spontaneously, the electron will return to its ground state by emitting the photon. Certain crystal structures increase the likelihood that the photon will decay into two photons upon emission, both of them with longer wavelengths than the original. Keep in mind that a longer wavelength means a lower frequency, and thus less energy. The total energy of the two photons must equal the energy of the photon originally fired from the laser (conservation of energy).
    When the original photon decays into two photons, the resulting photon pair is considered entangled.
    Normally the photons exit the crystal such that one is aligned in a horizontally (H) polarized light cone, the other aligned vertically (V). By adjusting the experiment, the horizontal and vertical light cones can be made to overlap. Even though the polarization of the individual photons is unknown, the nature of quantum mechanics demands they differ.
    To illustrate, if an entangled photon meets a vertical polarizing filter (analagous to the fence in Figure 4.4), the photon may or may not pass through. If it does, then its entangled partner will not because the instant that the first photon's polarization is known, the second photon's polarization will be the exact opposite.
    It is this instant communication between the entangled photons to indicate each other's polarization that lies at the very heart of quantum entanglement. This is the "spooky action at a distance" that Einstein believed was theoretically implausible.

    I worked as a consultant for the company that was awarded the contract for working on the zerodur glass block that made up the housing for the gyros. They brought us in to try and teach machinists optical fabrication. The tolerances needed for this thing were unbelievable, extremely tough even for a master optician. They manufactured 3 housing blocks, one of them was destroyed during the rough machining process, and an optician trainee who was attempting to polish one of the precision lands with a weighted polishing lap by hand fractured the second. They trusted the same company with the second block to complete the polishing process. They had limited experience with any sort of optical fabrication, and the specs they were looking for were way, way beyond the capabilities of this shop. I felt really bad for the guy, who was absolutely sick with himself after the accident, and perturbed with Stanford University with giving the polishing operation to this shop with very little expertise in optical fabrication. This block had a million plus in material and man hours prior to the polishing operation, wiped out with one bad stroke.

    Thanks, but I'm no longer on the inside. My frustration with the situation led me to make comments in front of the “wrong” people. Our shop was losing funding because the managers were turning down research projects from industry that would have kept the shop afloat many times over because the people getting the projects were not liked by the managers. and my previous years of excellent and outstanding performance reviews turned into sorry, we don’t have the funding to keep the shop going at full staff. DOH!!

    Like Galager replied when talking about the Preparation H commercials holding his hands out in front of him, if this is the problem, this isn’t the answer. I have worked in the bowels of the NASA beast for 7 years, and in this time I have seem waste, sloth and mindless bureaucratic nonsense that made my stint in the navy seem like a lesson in efficiency. What should take weeks takes literally years of power struggles, layers upon layers of management decisions, petty bickering and ineptitude being rewarded with promotions. I worked in a shop where cutting edge technology would allow us to perform a task in days, but due to management decisions, they “preferred” that we performed these jobs manually, and the project would take 1 to 2 years. The cost of the equipment would have been paid for with the price of 6 months of our labor. NASA was once a great entity, but after Apollo, it has degenerated into just another Government Hog at the public trough. I would love to see more manned explorations, just not run by NASA.

    I like the idea of taking back our economy from the globalists. However, you need to look at the realistic outcome of such drastic changes. In the short term at least, these moves would cause massive inflation, as our economy struggles with the readjustment. And the IMF and Central Banks would not allow us to wean ourselves from their iron grip so willingly. There would be extremely punishing moves as a total dump of more currency production, (hyperinflation) as well as a sell off of our T bills from most of the angered nations who are buying them with abandon. This in turn would turn our economy into a pre-WWII Germany take a wheelbarrow full of money for a loaf of bread scenario. Ultimately, we are going to have to do something to take our country back. Just be prepared for a total meltdown when we do.

    I had spoken with my State Representative and good friend, A Democrat, and even She was totally against this monstrosity. She is a full time government teacher at our local high school, and part time legislator. She said she could welcome the additional funding for state services, but was appalled at the lack of accountability in the bill. It would have gone down a rat hole of special interests, and pork barrel spending, with her and her fellow reps to be the ones deciding where the money needed to go. She was handing out vote no signs to all who wanted one. Her position and party spoke volumes about this bill.

    Dr. paul is right on the money with this. we are headed for a train wreak and I dont think the sheeple will wake up until it happens.

    As far as hands on experience, i worked at Compaq back in the late 80's, and have worked on my own computers ever since, but no formal working environment. All the jobs i see posted for this type of work seem to want at least a BS degree and 5 years experience. I am more than willing to work my way up from PC tech, so i am hoping that the school will at least get a door open.
    Thanks guys, I think yall might have killed my posting phobia,
    I have been lurking since Alamo Gal started getting curious, and i have always enjoyed the forum, but never wanted to post for fear of sounding like a total idiot. (Better to keep your mouth shut and be seen as a fool, than to open it and remove all doubt!)

    Dang, I need to turn my hearing aid down. I had been employed as a contractor for NASA for over ten years, just tried to stay away from all the bureaucrats there, but in the end it was petty politics that did me in. I just tried to do my job as best i could and not get involved with the us vs them thing that goes on at all levels of Government. My performance reviews were always outstanding. Didn’t hang with the right crowd I guess. They were talking of moving the whole optics group over to the army, but that move wasn’t supposed to happen till the next fiscal year. It was however, the straw that broke my back as far as wanting to remain in that field. I just want to move on, and this seems like a viable option.
