    Eek. I sympathize with your position, but what you're asking is really, really, really hard to do--particularly for a small independent retailer. There's somewhere in the neighbourhood of two hundred countries in the world, most with their own currencies, financial systems, and laws. We can't ask the 'little guy' to handle all of these independent regions. Not only would he be swamped, but the sales from many regions probably wouldn't justify the effort of setting up shop.

    Granted, things get a little bit easier when you're distributing mp3s--with no physical product to ship, there are no customs hassles. Nevertheless, just collecting applicable sales taxes--and submitting the appropriate paperwork--would be a nightmare.

    Then of course there's the opportunity for fraud. Many companies flatly refuse to process credit card transactions in certain countries because the chargeback rate is too absurdly high.

    I pay for spam: indirectly through my ISP's fees

    Are you implying that none of your upstream ISPs have spammers as their downstream customers?

    No, but that isn't exactly on point. Unless those spammers send their mail only to subcribers of the same ISP, then they (the spammers) are deciding that other ISPs--without the express permission of those ISPs--should bear part of their mass mailing costs.

    You pay indirectly for the ads which are sent to you on television, as well, through higher product costs. Should we ban that too?

    That's a false analogy. I may choose whether or not I purchase those products, and by so doing, I may choose whether or not I contribute to those advertising costs. With spam I do not have that choice--I pay for a company's advertising whether I buy their product or not.

    True--but First Amendment protection does not extend to making other people pay to present your advertising material.

    Use your own damn money to push your agenda--don't waste mine.

    All the spammers which are spamming legally already are using their own damn money to push their agenda. Email accounts cost money, after all.

    Now I'm starting to wonder if you're just trolling. Although in most cases spammers do indeed spend some money (sometimes large chunks of it--for anonymous mailing software, mailing lists, lists of open relays, etc.) in carrying out their trade, that does nothing to reduce the costs that they impose without my permission upon me. Question: Is it right to mug people as long as you spent a lot of money to acquire a handgun? Aside: In most cases, spammers are operating outside of the bounds of their terms of service with their respective ISPs. When caught, they usually have their accounts terminated--but this does nothing to aid all of the other affected parties in cost recovery.

    Spam is a problem that should be taken care of by the free market, not government.

    What is this mythical "free market" beast, and why is it so often a miraculous panacea? Spam is a consequence of having a free market. It is a form of advertising where the tarket market (not the advertiser) bears the majority of the costs, such that virtually any response rate above zero represents a positive return on investment.

    The "free market" does not exist--virtually all commerce is regulated in some way or another...and that includes other modes of advertising.

    More important, it is the advertiser that pays for other forms of advertising. I pay for spam: indirectly through my ISP's fees, and directly in terms of the time I waste on it. Unfortunately, the existing legal framework makes it difficult to recover or avoid those costs. Anti-spam legislation would protect my rights, not infringe on them. (Hint to advertisers: your First Amendment would not be abridged. Rent a billboard. Buy a newspaper ad. Set up a website. Use your own damn money to push your agenda--don't waste mine.)

    John Aristotle Phillips is the Princeton student who became world-famous when he designed an atomic bomb both to demonstrate the dangers of the proliferation of nuclear weapons and to fulfil his academic requirements.

    But once he designed the bomb, it wasn't long before newspapers interviewed him, television filmed him, girls chased him, foreign governments approached him, spies contacted him, the United States Senate congratulated him, Hollywood beckoned with its bent finger, and a Madison Avenue book publisher fought off the competition for the right to publish his story.

    This is the story, then, of what happens when an Obscure Individual becomes a Personality. It is the story of instant fame, of idealism, of success at a very young age, of college life today, and of a friendship that has resulted in the writing of this funny, fetching, edifying memoir of a glorious time spent in a marvelous cause.

    "We all know that sticking your head in a microwave oven is bad for you... right?" Microwaves induce movement of water molecules (when its in liquid form). so does your stove... why should we fear this without any hard scientific evidence that it is dangerous?

    This isn't because microwaves cause cancer--there still is no consistent corpus of evidence to support that hypothesis and there may never be--but rather because they cause heating. There are proteins within our bodies' cells that begin to denature at around forty degrees celsius. At or above this temperature (which actually isn't particularly warm), the proportion of exposed cells that die is a function of temperature and exposure time. (See, for example, James R. Lepock, "Protein Denaturation During Heat Shock" in Advances in Molecular and Cell Biology, Volume 19, pages 223-259, for an excellent survey of current thought on the mechanisms at work.)

    So microwaves are dangerous because they cause heating. Not only that, they can cause deep heating in localized hotspots. In other words, you may actually do damage to the brain, eyes, and other organs very quickly without having to burn through the layers on the surface first. (This is what makes microwaves more threatening than the stovetop. The heating elements don't burn unless you come into close contact, and they can't burn deeply without lengthy exposure.)

    How can they say they have the disease contained if they say, in their next breath, that they expect it to come back again?

    It's easy. The disease is contained (probably) in the human population. We know (probably) who all the infected individuals are, and they are being treated with appropriate precautions.

    SARS, however, is not a disease limited to humans. The original hosts are thought to be animals. Candidates include several mammalian species, as well as a number of birds. Right now, dozens of different species are being exposed to the SARS virus in labs on several continents, in an attempt to determine which animals may act as a reservoir for the virus.

    So, SARS is contained--but there is the potential for future outbreaks as long as the virus still exists in animal populations. Similarly, Ebola is usually readily contained when there is a human outbreak, but it keeps coming back because wild primates act as a natural reservoir.

    By your explanation, light passing by a mass should actually blue shift during approach and red shift again as it retreats. Does it not actually change direction?

    Light does indeed do both. As it drops deeper into a gravitational potential, it blueshifts; as it emerges, it redshifts. Its path will also appear to be bent by the gravitational field. (I could introduce you to a number of physicists who will adamantly insist that the light follows a straight path along curved space, but that's getting awfully picky.)

    Light cannot emerge from a blackhole because any photons emitted inside the event horizon get redshifted down to nothing on their journey out. They may indeed follow a curved path while they do so, but this is not essential to the process. Some physicists speculate that this bending has an interesting consequence right near the event horizon. In principle, photons on the right trajectories could orbit the black hole--kind of a neat thought experiment. Of course, any speculation about what goes on inside a black hole is merely that, since actual observations are rather difficult to come by.

    In the (near-perfect) vacuum of space, the solar sail is accelerated only by a direct transfer of momentum. If a photon is absorbed, its momentum is transferred to the solar sail, and it imparts a small acceleration (okay, impulse).

    But...if you have a reflective surface, then you get roughly twice as much momentum out of each photon. One kick comes from the incident photon, and one more from the departing reflected photon.
