  5. Re:Telescope? on IceCube Telescope Takes Shape Below Antarctic Ice · · Score: 4, Insightful

    I wondered about this, too. I don't think that telescope is incorrect, exactly, but it would be better perhaps to call it an Observatory.

    The key feature of a telescope as I interpret the word is amplification of visual phenomena. It makes tiny things seem big. Perhaps the nitpickers would say that the main feature of a telescope is that it can resolve finer and finer details - I'd say that's the same thing. An ancillary of this is that it tends to gather a large amount of otherwise feeble light from some small field-of-view so that, when that field of view is zoomed in to occupy the whole of a sensor (a camera, the eye, etc.) there is still something there to see.

    This neutrino detector doesn't have any sort of magnification in that sense. It doesn't even work in the electromagnetic spectrum! It's purpose isn't to zoom in on a phenomenon, but to detect it and tell us where it came from. It doesn't zoom in. By that token I would say that it is an observatory, not a telescope. It does, however, have light amplification through the use of photomultipliers. And, by virtue of its size, can be thought of as having better resolving power and sensitivity than its predecessors. By measuring neutron flux intensity as a function of angular position, it should be able to produce a sky map much that those from more conventional (optical, radio, IR) telescopes. Does this make it a telescope? I don't know.

    For comparison, the Compton Gamma Ray Observatory faced a similar challenge: it didn't have an aperture or light gathering and focusing mirrors common to "telescopes" of other wavelengths. It is not possible to do that with any materials we're familiar with - gamma rays are absorbed or pass right through; there can be no reflectance or refraction. GRO was, much like this neutrino experiment, a target that waited for gamma rays to pass through. Once they did the instruments would figure out their energy and where in the sky their originated from. Notice that they called it an "observatory", not a "telescope."

    This is what troubled me about the finding: Yeah, the Moon may have more water than the Great Lakes, but it is likely that most of that is very diffuse. So, you'd have to strip-mine cubic kilometers of regolith to get enough water for, say, a trip to Mars.

    all laws must be written in a Wiki with full history

    Sounds a like a do-able community project. How many laws within a particular scope change every day? Don't think all laws at first, start smaller.

    Most laws go by for years without change.

    If your government is not willing to do this, and it is still not happening then its just the laziness of everyone at large ; so stop complaining if you would like to see this happen.

    You can get plenty of up-to-date books or online databases that contain, for instance, the complete US Legal Code. You can also get information here and there about the history and intent of a law, and what it may actually mean in plain English. For some of the really arcane and abstruse stuff (and some of it really defies simplification) hire a lawyer.

    But what I think the comment in the summary was getting at was all the changes that go on while a bill is being written. Lawmakers, especially when they are going for a soundbite, carp on about last-minute changes that were made in the dead of night and buried in the text of a 1,000-page bill, giving us a billion dollar boondogle pork project in someone's district. They are right to do so - that kind of behavior is inexcusable. Lawmakers get away with it because it is so buried and unaccountable.

    Wikifying the bill-writing process would allow you to know that the text of a bill has been changed, and when, and by whom. Permit only elected members and the Congressional support staff (ya know, the people actually writing things) editing powers. As far as I know, Congress has absolutely no way to track changes to a bill as it makes its dirty, sausage-making way from concept through committee, debate and amendation, to conference, and finally ratification. For all I know it's just a Word file that gets spit out into a pile of paper. This kind of change-management system is common practice in many businesses where versioning and history are important - software vaults, part databases, etc.

    I can think of no place where this is more needed than Congress.

  13. Poor Graphs on Global "Last Mile" Performance Stats Going Public · · Score: 1

    The graphs at the Ookla Net Index are totally worthless.

    They demonstrate very crude trends, but without units on the time axis, who is to say if the increases are over the last day, month, year? Oh, wait, you have to read the sole paragraph of introductory text on an otherwise graphic page to learn that the graphs are rolling averages over the last 30 days. Silly me, instead of just finding it out from the graph, I was supposed to read something.

    The vertical axes likewise have no units - all you are told is the maximum value (i.e., the intercept at the right-side y-axis). We have no idea what the minimum value of the y-axis is. What is more, the y-axis scaling for all the graphs isn't consistent. If the maximum value of the South Korea graph is 34 mbps, then that should be the scale factor used for all the other graphs, such that the maximum value for the Netherlands, 17 mbps, should be about half as tall. Instead, each graph is individually scaled so that the graph intersects the right-side y-axis at 90% height, making any graph-to-graph comparison impossible. Better yet, graph all the countries on a single plot, so that the relative speeds among countries are blazingly apparent along with the trends.

    Without units on the graphs, the graphs add almost no value to the single number given to each country.

    They should have a look at any stock quote service and learn how to convey information from that. Here's a suggestion. See how nice and labeled the axes are? Look, you can expand the axes to see not just the last month, but any segment of the total historical dataset. Want to overlay how one stock does against another, here ya go.

    The 50 States map is pretty and all, but there isn't a scale that says what shade of orange/brown corresponds to what speed. Hover over a state and you get a number - but again with no units. Montana = 5.02. Whoopdie-freakin' do. 5.02 what? Mbps is the implied unit. But how do we know it's not density of internet users / sq km, or percentage of internet users that have taken their tests, or absolute number of testers, or per-capita consumption of french fries.

    Perhaps, but there's still the part where the whole rover gets covered in hundreds of pounds of dry ice. Maybe an RTG could have kept it from being buried, who knows.

    If RTGs get your heart going, just wait for the Mars Science Lander, scheduled for next year's launch window. It's an RTG-powered rover that should last on the surface for quite a while. How long? After 10 years, the RTG should still provide 100 watts.

    The two Viking landers were also nuke-powered, and Viking 1 lasted for some six Earth years (2246 sols). Opportunity only just passed Viking 1's longevity record last week.

    One other note about RTGs: it's not like you can just order them out of a catalog. They're expensive, they require a lot more intensive mission planning than solar-powered craft, and they are hard to come by. The RTGs that run on Pu-238 are in short supply, because Pu-238 is in short supply, because we aren't manufacturing nuclear weapons anymore. It is in part for this reason that the Juno mission to Jupiter will use solar panels.

    Joking aside, and driver distraction aside, this thing is illegal as all getout. I'm pretty sure that obscuring the dash (and things like, ya know, the speedometer) isn't permitted. Making the steering wheel harder to grip (and at the ol' 10 and 2 positions, no less) makes the vehicle harder to control. Putting a relatively heavy, knife-edged*, solid object right in front of the airbag is pretty brilliant, too. Ordinarily I'd just shrug my shoulders and say "ah well, natural selection at work," except there's a pretty good chance you'll take a few people out with you. I'm hoping that he means this as a joke.

    Fine idea, except that it's a technology that has yet to be demonstrated in Earth orbit. Most of the research in this area is for Earth orbiting collectors to beam many megawatts of power. There are numerous technical difficulties that still need to be addressed. The size of the receiver, for one thing. For an orbiting solar power plant, the receiver would be many square kilometers in size. For the small power budget of a rover (100-500 W), the microwave receiver would be much larger than the rover itself. Beaming the power as a laser would require a smaller receiver, except that a laser receiver is essentially a solar panel, and would be prone to the same dust-up the rovers experience. There are issues with consistent tracking, too. All in all, it's a whole lot of complexity that, for what was billed as a 90-day mission, really doesn't win out against plain ol' solar panels.

    For longer or more power-hungry missions, the preferred solution is nuclear-powered thermoelectric (RTGs), which is dirt simple, has no moving parts, a predictable and reliable power output, and high energy density.
