  1. Re:formations on Spaceflight Formation Flying Test Bed Takes Off · · Score: 1

    Increasing the distance between mirrors increases the effective radius

    Yes.

    while decreasing the distance increases the light collection capabilities.

    What makes you think that?

    but i fail to see how thats better than just using a rigid structure in the first place.

    Rigid structures are massive.

    bolt it together so it can be put together by 6 bots, and then taken back down the same way, and be hauled "up" in pieces.

    Many heavy and therefor very expensive pieces. Much, much, much cheaper to use ion engines, laser interferometers, and clever software to maintain relative position.

  3. Re:Compilation of facts are protected on Swedish Police Shoe Database May Tread On Copyright · · Score: 4, Informative

    As far as I can tell from the article no shoe company has complained. It appears that some professor has merely speculated that the database may infringe copyrights.

    I agree with the suggestion that they would get better quality data by working with the manufacturers, though.

    Oh, I am completely sure that this isn't profitable, because registrars and ICANN would crack down on it immediately...

    If there was a $10 cash in advance initial fee for a domain and a five-day wait before activation...

    ...and credit card companies would quickly reverse fraudulent puchases made on these websites...

    They will, but how many people ask? Even if 90% of charges fail to stick many of these scams could be profitable. How many people bother to ask that the charge be canceled when it's only $9.00?

    ...and then pass on the fraudsters' information to law enforcement...

    They will provide the information if asked. It is up to the victims to file complaints and to law enforcement to investigate. Why don't they?

    So get rid of them in the name of health, and pretty soon the school has no football or basketball team. Which is healthier? Playing sports and cooling off with a cold cola afterward, or drinking water while sitting at home on the couch playing video games?

    What do varsity sports participated in by a few privileged jocks have to do with exercise for most of the students?

    They are referring to expensive nanostructured titanium dioxide used in some solar cell technologies. The reporter, of course, is oblivious to the difference between that and the pigment in white housepaint.

    Given that the only way we could see this amazing sight is it to be "flat" to us in our line of sight...

    It's an amazing coincidence that it is flat on, but we'd still see it if it was at an angle. It' would just look oval rather than round. It would have to be nearly edge-on to be invisible.

    Makes me wonder the same thing about all the planet hunters and exo-planets that we are finding - how many more would we be able to find if it didn't rely on having just the right angle from our vantage point...

    Assuming that the angle is random, the calculation should be straightforward. I'm sure it's been done.

    You can get quiet ballasts. There are also many choices of color other than "cool white" such as "daylight", "deluxe warm white" etc. but make sure maintainence is instructed to use correct replacement lamps. As someone said earlier, hire a lighting designer.
