Going ahead a generation or two, resources will be depleted, and the few remaining people there(and here) will try to adjust to an ox cart driven economy. |

On Feb 9, 3:09*am, Robert Clark wrote: (Bronze Age cultures destroyed by widespread use of iron) *If it is the case that very dangerous weapons and the means to deliver them world-wide might become wide spread, could we have any defense against them? Is there anyway to prevent their use for destructive purposes? * What specific weapons did you have in mind that cheap diamond would make more widespread? Some free speculations... [1] Diamond is much stronger and stiffer than the glass currently used to make telescope mirrors. This will allow their use for making mirrors much larger than the size currently possible for a single mirror. Since, I hypothesize, space travel will become routine during the "Diamond Age", lofting numerous such mirrors will be technically feasible. This would permit real-time monitoring of any place on Earth with submillimeter accuracy with such mirrors aimed back at Earth for surveillance. Some recent research with "terahertz" frequencies suggests such imaging would even be able to penetrate walls. Would we want such intrusive surveillance of every moment of our lives if it could prevent war and crime? * Very stiff mirrors are what you DO NOT want for extreme precision imaging from orbit. You want very flexible mirrors so that they can be actively distorted to compensate for atmospheric turbulence. * Now, a diamond framework for the flexible mirrors to be braced against... * Also, my Google-Fu failed to find specific numbers on diamond's transmission or reflection characteristics in the terahertz range. [2]The idea of everyone being able to look in on everyone else would be a radical one in human culture. It would mean the complete lack of privacy at all times. If we were to accept this, could we go one step further? Could we even allow open access to our thoughts to be shared at all times? This is a capability that might be close to being possible: * Privacy is relative; if you really want to keep a secret, tell NO ONE. Well, but that's why the people with actual economic future brains in the stooge Oprah-controlled US build nothing but On-line Banking, On-Line Publishing, RISC++, Bi-Optical Computers, Post AT&T phonics, and Post GM Robotics. Rather than Diamonds, though. ON SCIENCE Sharon Begley Mind Reading Is Now Possible. From the magazine issue dated Jan 21, 2008 "A computer can tell with 78 percent accuracy when someone is thinking about a hammer and not pliers."http://www.newsweek.com/id/91688 Technology The Silent Speaker David Armstrong 04.10.06 NASA researchers can hear what you're saying, even when you don't make a sound. "When we speak aloud, we're forcing air past the larynx and tongue, sculpting words using the articulator muscles in the mouth and jaw. But these muscles go into action regardless of whether air is sent past them. All you have to do is say the words to yourself and you're sending weak electrical currents from your brain to the speech muscles. Jorgensen's trick is to record those signals (known as electromyograms), process them with statistical algorithms and compare the output with prerecorded signal patterns of spoken words, phrases and commands. When there's a match, the unspoken turns into speech."http://www.forbes.com/free_forbes/2006/0410/084.html?partner=yahoomag * Tell no one, not even YOURSELF! Then you could imagine an orbital surveillance system able to resolve changing patterns on the skin within resolution of a few microns would also be able to read this as well remotely. * Um, only if it can tell what I'm subvocalizing via my scalp. Tinfoil hats, anyone? [3]If the electrical firings of our thoughts or muscles can be read remotely, is it possible a genetic mutation could allow humans to do this innately? The electrical pulses produced by our thoughts or muscles are so small it would seem impossible that this could be done in nature. But there is the case of the shark that has a fantastically sensitive ability to detect variations in electric fields: Electric Gel Gives Sharks Ability to Sense Heat. January 30, 2003. "Brown recovered gel samples from a black-tip reef shark and a white shark captured off the Californian coast, and tested them in a lab. He applied heat to one end of the sample holder and measured the change in the electrical field as the temperature shift moved through the gel. He calculates that the gel delivers 300 microvolts of electricity for every 1ºC change in water temperature. Previous experiments with sharks have suggested that the sensors start firing in response to just 0.05 microvolts."http://www.flmnh.ufl.edu/fish/sharks/innews/electicgel2003.htm This is an idea written about quite frequently in science fiction where you have an alien culture where they have a sort of group mind. This is usually something regarded with horror in the stories, but would it be if it allowed the species to survive? * Somehow I doubt this would work in air. If it did, some critter would have tried it by now, I'd think. [4]Speaking of genetic mutations, could we induce a genetic mutation so that no one would want to do harm to their fellow man? There has been much research lately over particular personality traits that may have a genetic component. Could we insure that everyone perhaps by a genetically engineered virus had the "altruism" gene? This would raise the specter as well of a genetically engineered viral weapon. There is also the question of unintended consequences where something seen in humanity's best interests has unforeseen negative consequences. * ObSF: Story by Niven with telepathic, nonviolent Neandertals. * Notice that they are extinct and we're not. [5]Instead of imagining such radical changes in human nature and/or culture, could we just create a shield against any known weapon? * Obvious workaround, invent NEW weapons. Anyway... The recent experiments with "levitating frogs" makes clear that any body or particle can be effected by magnetic fields of sufficient intensity, not just metals. Then you can imagine force fields on this basis able to repel a material projectile, metallic or not. You would need quite a lot of power to do this with large bodies or high speeds. Possibly the idea of the projectiles own energy being used against it could come into play. The projectile impinging on the magnetic field would cause induced eddy currents which could be used to create more energy that could be used to produce a bigger field to repel the projectile. * Exactly how do you propose to project multiTesla fields dozens of kilometers, oherent "magnetic beams"? That flew in John W. Campbell's heyday, but not now. OK for material projectiles, but what about energy weapons? At low intensities you could have a material shield. But suppose it was at high intensity or of highly penetrating wavelength or you wanted the shield over an entire city? One possibility might be to convert the energy into matter then use the magnetic shield method on the matter produced: Out Of Pure Light, Physicists Create Particles Of Matter. "ScienceDaily (Sep. 18, 1997) — A team of 20 physicists from four institutions has literally made something from nothing, creating particles of matter from ordinary light for the first time. The experiment was carried out at the Stanford Linear Accelerator Center (SLAC) by scientists and students from the University of Rochester, Princeton University, the University of Tennessee, and Stanford. The team reported the work in the Sept. 1 issue of Physical Review Letters."http://www.sciencedaily.com/releases/1997/09/970918045841.htm * Parry a high-energy laser beam with another that converts enough of it to particles that scatter the rest of the incoming beam harmlessly? * Mark L.
