    But your one-farad capacitor comes with a limitation that most capacitors don't have—it'll undergo dielectric breakdown if you applied more than 12 volts (or 12 volts plus some engineering margin). Most capacitors you find in your electronics components drawer have somewhere between 50 to 200 volts rating.

    Overcoming one limit often involves a trade-off in another limit (for a more fundamental example, consider squeezed light). For this airplane, it has already made some of the trade-offs (wingspan per payload). What other trade-offs can it still make and remain viable as practical propulsion mechanism?

    Yes. Because it's the "spend" part that necessitate the tax (explicit and implicit). As long as you do the "spend" part, how you exactly fund it is irrelevant.

    P.S. I guess to be pedantically correct, "Borrow and Spend" is more or equally fiscally responsible (or irresponsible) than "Tax and Spend".

    It might depend on parts of San Diego (haven't spent enough time there to know), but in summer, it feels way too hot. This year might have been an anomaly, but the only livable part of California this summer was SF Bay Area (... kinda ironic now, I know).

    If the map can't distinguish between San Francisco and Walnut Creek through the Caldecott tunnel, then it's not discriminating enough.

    When it comes to climate, there's the "good enough" (a lot of people tolerate Florida or Hawaii weather), and there's the "best". Apparently my standards are higher than yours.

    And we detected gravitational waves:

    Both of which were predicted before 1980s. We have a draught in physics theory results.

    It would have been far more interesting if we never detected gravitational waves (would mean something is wrong with Einstein's general relativity), or if we never detected Higgs boson (would mean there is something fundamentally and structurally wrong with the standard model).

    California has an advantage that no other state or city (never mind Detroit) ever had: natural geography. Find me a city in the entire world with more temperate climate than San Francisco (that is, outdoor temperature close to 70 deg F year-around), and you will have found a city that can be run just as badly while people still flock to it.

    I think of California as a very beautiful woman (geography) with terrible personality (government). Despite what people say, the personality only starts to grate on you when the beauty fades.

    That's right.

    P.S. Replying to say that Wikipedia did list the value of Planck's constant as newly defined: h = 6.62607015 * 10^-34 J*s. What's special about this value is that it's exact (note the lack of specification of experimental uncertainty), so if you were to write it as h = 6.626070150000000000000 * 10^-34 J*s, as annoying as that might be, you are not wrong (all those zeros—and more—are significant).

    P.P.S. I guess they didn't update the table since the value is not effective until May.

  16. Re:Gravitational Field Varies on Kilogram Gets a New Definition (bbc.com) · · Score: 4, Informative

    Yeah, they should have left out the Kibble balance part. That's more confusing than illuminating. In terms a layman can understand, kilogram is now defined the same way meter is: by defining a related physical constant to be an exact value.

    Meter is defined today not by a physical object, but by defining speed of light to be exactly 299,792,458 m/s (that is, in significant figure terms, there are significant zeros following the decimal for-ever). With time defined by the atomic clock standard, this definition of speed of light also defines what a meter is (and many different experimental arrangements can be designed to use this relationship to actually calibrate real object).

    With the vote today, kilogram is now defined by defining Planck's constant to be exactly 6.626070040 * 10^-34 kg*m^2/s (um, Wikipedia's not updated yet; the exact value they chose might be different from this number; important thing is that the value they chose now has infinite number of significant figures). Since meter and seconds are already defined, defining this constant defines the kilogram, and clever experimentalists can come up with better methods than Kibble balance for calibrating any local kilogram standards.

    P.S. BTW, for scientists working in precision measurement area (the area NIST and NSF funds as they relate to fundamental science), this is an exciting news. It's a validation of accomplishments of their field, on the same (or possibly greater) magnitude was when atomic clock standard was adopted for the definition of second.

    In Amazon's case, "monopsony" is literally the wrong word. If it were a traditional retailer like Walmart, then, yes, you can make the argument that Walmart is "buying" from the suppliers (and then re-selling it to the consumers). The way Amazon works with people who don't have a negotiated relationship with them, they are literally not a buyer—they merely connect sellers to buyers as a middleman that takes a cut.

    P.S. The term "monopoly" makes sense, because they are providing a service. There is no way to read "monopsony" in a way that makes sense for Amazon's case.
