    Bad math doesn't prove yours.

    33,551,983 voters
    * Remain = 16,141,241
    * Leave = 17,410,742

    33,551,983 voters
    * 20% "educated" = 6,710,397
    * 80% "uneducated" = 26,841,586

    6,710,397 "educated" voters
    * 53% Remain = 3,556,510
    * 47% Leave = 3,153,886

    % "educated" voters amongst Remain = 3,556,510 / 16,141,241 = 22.03% > 20%
    % "educated" voters amongst Leave = 3,153,886 / 17,410,742 = 18.11% < 20%

    The fraction of educated voters in the leave camp is therefore lower than in the general voting populace.

    "cis" literally means "on this side of", just as "trans" literally means "on the other side of".

    cis-lunar space can be loosely defined as that part of space that is within half a million km from Earth (which includes the Moon itself, as well as all the Earth-Moon Lagrange points).

    Over 6.4 billion kilometers, actually...

    The oft-stated 510 million kilometers is merely the current distance between Earth and 67P Churyumov-Gerasimenko.

    It's taken Rosetta quite a journey to be able to match orbit with the comet.

    Mercury's diameter is 2.11 times that of 134340 Pluto, but its mass is 25.3 that of the puny dwarf planet.

    Discounting metallic hydrogen on Jupiter and Saturn, Mercury's definately the most Metal planet in the solar system.

    Juno's mass is listed as 3625kg, or almost 8000 pounds, not almost 8 metric tons.

    As for the energy obtained from "falling several hundred million miles": that would be exactly the same energy it took to get that far "up" in the first place (not saying that there's no energy to steal from Jupiter, but it's a pretty hair-brained plan, imho, not in the least because such a trajectory would probably take the better part of a decade to complete).

    Last time I checked, the Pacific was shrinking; You might be confusing it with the Atlantic and its mid-oceanic ridge.

    Of course, over a sufficient timespan, your argument might hold water (or rare earth elements); Then again, with enough time it'd apply to every centimeter of the Earth's surface.

    The Blackbird craft has a ratchet in its drive system which categorically prevents the propellor from ever powering the wheels, whether by air interaction or by discharging built-up/stored rotational momentum. Its presence (and verification of functionality) was mandated by the organisation refereeing the record attempt (NALSA).

    They will just have an army of lawyers waiting at the runway for them when they come back down to earth.

    Not if you fly Soyuz.

    Which is what anyone wanting to get to the ISS will have to do in a year or two, until US commercial transport becomes available another few years down the line.

  17. Re:Floating Mountains explained on The Science of Avatar · · Score: 1

    Earnshaw's Theorem doesn't apply to diamagnetic materials (e.g. superconductors). For such materials Earshaw's formulas dictate the exact opposite they do for dipoles and paramagnetic materials: diamagnetic materials can be stable in all directions at once, but not unstable in all directions at once (both can be stable in some directions and unstable in others at once, though).

  18. Nearest sextuplet on Big Dipper "Star" Actually a Sextuplet System · · Score: 5, Informative

    In case anyone was wondering (and since TFA doesn't mention it), the nearest sextuplet star, is, of course, Alpha Geminorum, a.k.a. Castor, the second-brightest star in the zodiac sign of Gemini, a.k.a. the Twins. It's some 50-odd lightyears away.

    Note that Beta Geminorum, a.k.a. Pollux, is actually the brightest star in Gemini (whether Johann Bayer labelled Castor as the alpha star because it rises first in the night's sky, or because mythologically, the twins are always labelled "Castor and Pollux", is unknown). Pollux is a single star, with one confirmed exoplanet, Polydeuces orbitting it.

    You can (somewhat) blame the Japanese for holding up the start of the project; It wasn't until they were bought off with a separate research facility that they dropped their claim on the reactor location.

    Oh, and by the way, ITER is not just an EU project. It's about as international as the International Space Station (minus Canada, plus China).

  23. Re:Viewing schedule on Heavens Above on ISS To Become Second Brightest-Object In the Sky · · Score: 1

    The only changes in the ISS's orbit are caused almost exclusively by:

    • Atmospheric drag
    • Reboost maneuvers
    • MMOD (micrometeorite/orbital debris) avoidance maneuvers

    All of these do virtually nothing to change the orbital plane of the station, which is â"at an inclination of 51.6 degreesâ" optimal for Russian launches only (and we're bloody grateful for their participation, with US access to the station going away for an indeterminate interval starting 2011).

    The type of orbital plane changes you allude to would require massive amounts of energy and/or propellant, neither which is available (even with the final segment of the US power truss in place).

  24. Re:hubble mistakes? on The Herschel Telescope Close To Blast Off · · Score: 5, Informative

    As described in here, the point of putting the observatory in a Lissajous orbit around the Earth-Sun L2 Lagrange point is to have the three nearest and largest sources of infrared light pollution (the earth, the moon, and the sun) sufficiently far away and in the same hemisphere relative to the observatory, allowing for a clear viewing angle anywhere in the other hemisphere.

    Drive manufactures in that case found every way possible to round up, including using 1000 bytes as a KB when it is only a KiB.

    Actually, the size of a KiB (Kibibyte) is not in question, it's most certainly 1024 bytes. The kB (Kilobyte) on the other hand, is used by drive manufacturers to mean 1000 bytes, and in this they are only following IEC, IEEE and ISO standards.
