  1. Re:Modifing to target wasps instead on Roundup Weed Killer Could Be Linked To Widespread Bee Deaths, Study Finds (npr.org) · · Score: 1

    Generally the sites where wasps (especially the exceptionally common paper wasp) build their nests are not attractive nesting sites for any kind of bee, so the collateral damage is generally pretty low.

    Wish that were completely true.

    The sites that are good for artificial homes for mason bees, leaf-cutter bees, and several other solitary (non-hive-living) bee types (under overhangs for rain shelter, east-side for quick wake-up/warm-up at dawn) are also the preferred sites for many kinds of wasps. (The bees also prefer natural holes in the same sort of location, for the same reason it's good for artificial homes.)

    Also: Some of the small wasps that prey on these bees like the same sized hole, though whether this is for their own nest or because they know where to hunt is not clear to me.

    All the known theories of physics predicted that the electrons would adhere to the six-fold underlying pattern, but instead, the electrons hovering above their atoms decided to march to their own drummer -- in a straight line, with two-fold symmetry. The decoupling between the electrons and the arrangement of atoms was surprising enough, but then the researchers applied a magnetic field and discovered that they could turn that one line in any direction they chose. Without moving the crystal lattice, [one] could rotate the line of electrons just by controlling the magnetic field around them.

    Sounds classical to me:
      - The layout of the substrate produced a planar potential well with no, or very little, difference of energy for electrons being in one position vs. another.
      - Provided the average density of the electrons was right, they behaved like a gas of individual particles in a thin container, or marbles on a flat surface.
      - The electrons repelled each other, so they tended to spread out evenly. (Spread out too far, though, and they leave some positive-charged substrate behind. So they don't just fly apart and go away.)
    - But electrons also have spin, which means they are little magnets. So, with their mutual repulsion largely defeated by forces holding them at a given average spacing, they tend to line up north-pole-to-south-pole in strings (but don't all pile up because coming more than a little closer together under the slight magnetic attraction is balanced by higher repulsion.) The strings are a bit more dense than the average gas, so most of the electrons join one and reduce their total energy.
      - So now you have these long magnetic strings, with no preferred orientation driven by irregularities in the substrate. Bring a magnet nearby and they'll line up with its field while spacing out by mutual magnetic AND electrostatic repulsion, much like iron filing lines.

  15. Let's get it right. on Tesla Stock Plunges After Senior Execs Leave, Musk Smokes Weed During Interview (arstechnica.com) · · Score: 3, Interesting

    People are pulling out of the market because Elon lies to manipulate shareholders and cost them billions and that has become even more obvious.

    I don't have any reason to support Musk, but when flaming him let's at least get it right.

    What he's being investigated for is not alleged lying to cost stockholders billions.

    What he's being investigated for is alleged lying to cost stock traders - possibly stock manipulators, billions. Stock traders and hypothetical manipulators who DIDN'T own any stock, BORROWED and SOLD a bunch in the expectation that it would drop, some of whom apparently hired, through cutouts, a bunch of trolls to talk the stock down.

    So when he said (unfortunately for him, without cutouts) that they might be going private and the stock shot up, the people who sold the borrowed stock were stuck having to buy some back at a HIGHER price than they sold it for (which is what you risk if you sell a stock short), but the people who actually owned it were just fine.

    So the shorts closed out some short positions and took a big loss. Then, since Musk said that in a way that COULD be traced to him, they were able to sue him for the losses and complain to the SEC, getting it to start an investigation. THEN the stock DID start to tank, and the people who owned it DID take a loss.

    But I wonder: Did the shorts actually close out all their short positions? Or are they still net short on Tesla - especially if you count, not just their direct holdings, but also all the investments of the web of companies and financial instruments in which they hold some interest?

    Seems to me that, if they still have a short position, getting an SEC investigation going and/or announcing and filing a suit for billions would be just the sort of manipulation that they are claiming Musk was up to. Hold a short, file a suit, talk it up. Maybe switch to long and then settle and announce the settlement. And so on. (Always through cutouts, of course.)

    IMHO anybody who sues over stock manipulation should have no net position (outside of a truly blind trust) in the stocks or other financial instruments whose performance might be affected by news of the suit and/or its progress.

    A good move for Musk might be to investigate the plaintiffs, see if they might have had a net short position when they filed and/or announced their suit and/or complaint, whether they profited by it, and if so counter-sue, get it on record, and maybe not just get out from under but suck a few more billion out of them and into the company. (This would also establish the precedent of "gotta divest before you sue or you're manipulating", if it isn't there already. I am not a financial type or a lawyer.)

    In the interest of full disclosure:
      - I have no direct financial position, short, long, bond, etc. in Tesla (or other Musk enterprises).
      - I don't know if any of the funds in my retirement plans might have a position ditto.
      - As far as I know, neither my company nor any in which I have a financial interest (again, outside of any retirement plan funds), are currently engaged in any business or other relationship with Tesla, etc.

    One antenna I'm working with currently is for BLE - on the 2.4G band. The quarter-wavelength there is about 1 1/4 ". But the antenna is mostly a chip of ceramic, with some horrendously high permittivity. (Ceramics can get to 6k or so, though I haven't computed the scale of this thing to estimate its permittivity.) So the quarter-wavelength, in and immediately around the chip, is scaled down in proportion, making the antenna about the same length as a surface-mount capacitor, though substantially narrower. The energy density is also scaled up (in proportion squared), and by the time the wave has expanded to the size of a free-air quarter-wavelength antenna the energy density is down to just that of the larger antenna.

    On the receiving side it still works - sort of. But the energy density of the incoming wave doesn't scale up at all when the antenna shrinks. So it intercepts only the tiny amount of energy that passes within a scaled-down quarter-wavelength around the scaled-down antenna, rather than that passing withing a free-air quarter wavelength of a free-air quarter wavelength metallic conductor.

    So one of these for transmitting and one of the invention for receiving (if it also works at such a tiny size) and you have your ultraminiaturized two-way system.
