  1. Re:IANA Physicist, So... on Navy Debuts New Railgun That Launches Shells at Mach 7 · · Score: 2

    Radar can spot the incoming shell.

    You can defend against it with a similar projectile fired to intercept (not easy, but would work if you got it right)

    (Ex Navy Nuke here)

    True enough, but isn't food a little more compact and easy to procure than jet fuel for carrier flight ops?

    I was thinking more along the lines of the "fuel ship" staying on station in-theater, and swapping crew as needed, forgot about the food, but I suppose that would happen at the same time that people rotate back to shore.

    The onboard nuke can cruise an aircraft carrier at 30+ knots. If this tech can fit inside a fuel bunker ship with a carrier nuke to power it, then you've got a bunker ship that never needs to return to port...

    They raised the rent on my old-ass cable modem. First from $3/month to $7/month, and then this year to $8/month. This for something that has probably been depreciated for years. Can you imagine if you brought home your new car and a year into the lease they doubled the "rent"? What a fucking ballsy move.

    They're thinking like landlords with an apartment building... and, someday, your modem will die and they'll have to give you another one - $40 out of their pocket, gotta bank up for the day that happens.

    The media was playing up the "maybe somebody stole it" aspect from the very start.

    If you've ever flown over ocean, out of sight of land, or on a polar crossing route, that feeling that you're really "out there," was true. It's a big world, after all.

    Europe and Japan are now seeing decreasing population without massive scale plagues or slaughter.

    Alas is it impossible to have all places on Earth to have a civilization level of that quality :-(

    This is a relatively new phenomenon, and I disagree that it's impossible to cover the world with this level of education- perhaps distasteful in the short term.

    What you left out about the spoils of war was that in addition to the post conquest population boom, there's also those wonderful plagues that get spread around, just look at what smallpox did for the population of North America (no clothing required, white skin vs red...)

    If the civilized world would stop sending token charity to the third world, there would be quantifiably less misery (when misery is quantified as the product of population X how miserable they are...)

    Let's be modern and use the orbit of Neptune as the solar system's diameter: 9,000,000,000 km, and put Alpha Centauri at 4x10^13 km, so, we're looking at a ratio of 4444:1. Diameter of a dime is 18mm, so the equivalent distance to Alpha Centauri would be about 80 meters.

    (Is it a problem if we need more people dedicated to taxes and other government forms than we have programmers, marketing people, or customer support staff?)

    Unemployment hovers around 7-8% today, what would it be if taxes were so simple that they "did themselves" with 20 hours a YEAR of effort per business?

    If the U.S. wants to become more competitive in the global economy, we might consider streamlining the tax code. Unfortunately, I think we're all more interested in pork projects for our local area than anything as lofty as global competitiveness.
