  8. Re:Using a laser? on Optical Cellphones · · Score: 2

    Um. I think your're a bit confused on how bandwidth works.

    Take the AM radio range. 500 khz to about 1500 khz. That's a span of 1 mhz. That doesn't mean a 500 khz transmission will be able to transmit 500 khz of data, however.

    Let's say to transmit a low-quality AM voice signal, you need a 10 khz-wide channel. That will allow 100 channels on AM. But for the 500 GHZ to 1 Thz. range, that will allow for 50 billion channels. Bandwidth is exactly that, width on the electromagnetic band. It has nothing to do with the frequency of the signal. 1 THZ signals can't be modulated any faster than 1 KHZ signals.

  9. Re:Using a laser? on Optical Cellphones · · Score: 4, Interesting

    Lasers are out of the question for this. Lasers produce a very narrow collumnated beam. No good for cellphones. Probably something more along the line of bright LEDs would be better.

    Big lasers, with lots of power. Could be dangerous.

    It wouldn't need to be high power at all. Hobbyists have been experimenting with optical wireless communications for several years. It's not dangerous. Although the hobbyists use fixed points with either lasers (milliwatt power) or focused LEDs to transmit light. This DoD thing seems pretty crackpot to me. Why not just use high frequency microwaves? (Probably around 500 ghz to 1 thz) You have all the bandwidth you could ever use for cellphones in that range, and you wouldn't need fancy optical devices like super-sensitive photodetectors.

    X-rays are light energy, and they don't seem to have a problem passing through.. well.. you, among other things.


    Um, xrays, gamma rays, optical light, radio waves, and everything else is electromagnetic radiation. The penetration ability changes with different wavelengths. Low frequency, long wavelength radio waves penetrate through objects very easily, this is why 2.4 ghz 802.11b goes through walls better than 5 ghz 802.11a.

    Higher frequence microwaves, infrared, optical, and UV em radiation is basically line of sight. Ultra high frequency, high energy, sub microscopic wavelength xrays and expecially gamma rays can penetrate most materials due to their high energy.

    Actually, there is quite a bit of free iron on the surface of the moon from asteriods, about .05%. This can be extracted simply be running the soil past electromagnets.

    Also, you could have a fiberglass composite inflated structure (very lightweight) with a couple feet of rocks piled on top to protect from radiation.

    You'ld freeze before you'ld suffocate.

    I disagree. Yes, space is very cold, but the vacuum acts like a thermos bottle. You would only have radiant heat, which is actually very little. You would stay quite warm. You would suffocate in about 2 minutes and stay conscious for 10 seconds.

    BTW, one guy (from NASA) was depressurized once during training. He was able to escape the chamber, which was in a vacuum, completely conscious and no worse for wear.

  13. Re:Exposure to vacuum on NASA Considers Abandoning ISS · · Score: 5, Informative

    You will not explode in a vacuum, provided you exhale before depressurization. In space, you would remain concious for about 10 seconds (this happened to one person who was accidentally depresurized during training.) and you would live for about 2 minutes. It takes a long time for the blood in all of your tiny little capillaries to boil off and cause swelling, long enough for you to die of asphyxiation before you have to worry about that.

  14. Re:Well... on RadioShack Stops Being Nosy · · Score: 3, Interesting

    Anyway, who needs Radio Shack? They;ve alienated their core customers in a futile atempt to compete with the Circuit Cities of the world. If you want a little cruel fun, go in there and ask them where they keep the 100 microFarad capacitors.

    Radio Shack has compressed their electronics section down to the metal cabinet because it is more profitable to sell other things. With the advent of such things as PCs, electronics tinkering just isn't nearly as popular as it used to be. When you add that to the fact that electronics components are ridiculously cheap, you can start to see that there is little money in being an electronics hobbyist store. It's more profitable to sell computers and PDAs, even if you don't sell very many.

    Although, they could have more electronics than they have right now. Radio Shacks could get rid of all their useless shit that never sells (about half of what's in the store) and maybe make a bigger electronics section.

    I remember a Dilbert cartoon in which he went to "Radio Barn" and tried to buy some resistors or something. The clerk refused to help him, as it was not worth his time to ring up a total 10 cents worth of resistors. When dilbert persisted, the clerk got pissed off and gave Dilbert the resistors for free.

    The honey bee only has a few tens of thousands of neurons. I really can't see how that would be 60 teraflops. Neurons operate at less than one kilohertz, usually. So you're talking about maybe 20 million operations per second.

    Of course it is much more powerful than a 20 mip computer, because the bee has the advantage of many neural interconnects, allowing for greater flexibility and computational power. However, still, the fact remains that a single neuron can't do more than about 1000 operations per second.
