  2. This story is misleading. Is the concentration of nutrients going down? Yes. Is that a problem?

    Well...

    As it turns out, what's really happening is the carbon dioxide is promoting bulk growth, which is making more food (particularly, more carbohydrates) in the same amount of time. However, the nutrients are getting stocked into the food at the same rate.

    So, the total carbohydrate loading is increasing, making food bulkier. But the total nutrient loading in the food is the same. Since the bulk is larger with the same nutrient loading, the concentration (nutrients per unit bulk) goes down.

    Clearly by my verbiage, I'm not a botanist. And I'll say I'm not a climate change denier. But it's not clear to me why this specifically is a "problem" per se.

  3. Why Does it Need to be a Great Circle Route? on The Longest Straight Path You Could Travel On Water Without Hitting Land (gizmodo.com) · · Score: 1

    Why does it need to be a Great Circle route? A Great Circle route is a route that follows an arc of a circle whose origin is the center of the Earth. But if I plot a course to follow a line of Longitude such that I drive around Antarctica, I've followed a straight path but just not a Great Circle route. There's other non-Great Circle routes that go at an angle, the only key is where the origin is of the circle. On top of that, limiting to just Great Circle routes make the additional fallacious assumption that the Earth is a sphere, when it's actually an oblate spheroid: it bulges at the Equator, so the Great Circle that is the Equator is actually larger than a Great Circle that passes through the poles. (For clarity: it's really really close to a sphere, but they're looking for extremes so it matters.)

    Not saying the solution won't be a Great Circle route - It likely will be, since that's the theoretical biggest possible straight line. But there's no reason is *has* to be.

    Concur. The question is "why is Einstein famous." The adult answer is that he was an inflection point in scientific progression, more than most other really famous scientists; the adolescent answer is that he single-handedly changed science.

    Basically:
    1. Aristotle invented science.
    2. Newton called shenanigans on Aristotle's work, and invented both correct science and the math to support it.
    3. Einstein changed the gears of the scientific community in ways we're still trying to figure out the details of. Einstein demonstrated that Newton was only correct in special cases (that happen to be our everyday experience), and that the Universe is really really weird once you get outside the special cases.

    You remember reading that? So, you were old enough to read. I remember watching Wiley E Coyote get an anvil dropped on his head when I was... younger than Kindergarten. I definitely didn't realize that wasn't real; I vividly remember trying to figure out how Mr. Coyote's body could bend like that from the anvil, and thinking the 12-inch lump is what really happened when you get a big hunk of metal dropped on your head. I definitely had some level of "grok" regarding death, but for comedy- and cartoon-vs-reality, especially 40s-era slapstick, that conceptualization happened somewhere around 1st grade.

  7. The Law of Differential Masses says the larger ship gets right-of-way. The Law of the Sea, or more correctly the United Nations Convention on the Law of the Sea as well as the International Regulations for Preventing Collisions at Sea, says the more maneuverable vessel is the give-way vessel, but only when higher levels of responsibility aren't present.

    An example of a higher level of responsibility? How about International Rule 8.f(iii), as defined by the US Coast Guard Rules of the Road: "A vessel, the passage of which is not to be impeded remains fully obliged to comply with the rules of this part when the two vessels are approaching one another so as to involve risk of collision."

    Or the Inland version of the same rule: "A vessel the passage of which is not to be impeded remains fully obliged to comply with the Rules of Subpart B (Rules 4-19) when the two vessels are approaching one another so as to involve risk of collision."

    Or the English vernacular version: "Fuck all if you have right-of-way, you still have responsibility to avoid going bump." Which means even if the destroyer's driver was an ass-hat and was 99% in the wrong, if the merchant was making way under her own power then she cannot avoid her own responsibility.

  9. The problem is that what a quantum physicist refers to as a "wave function" does not directly relate to the EM waves themselves. What's being referred to is that the specific properties of a particle (location, momentum, time, etc) is not deterministic, but rather probabilistic. And when you plot this function, the result looks remarkably "wave-like" in that the probabilities are not continuous, but rather they have highs and lows, or peaks and troughs.

    https://en.wikipedia.org/wiki/...

    Enter Heisenburg and his "uncertainty principle." it holds true that you cannot know all properties of a particle until you measure them, but until you measure them ALL possible states are not only possible... but in fact the particle is *actually* in all possible states at the same time. It's only when you measure it, does the particle "choose" where it wants to be. This is called "collapsing" the wave function - of all the possibilities that it can be / is, it suddenly resolves to only one of those possibilities.

    So to answer the question: it has nothing whatsoever to do with radio.

    Where things get even more interesting, is that two particles can have a causal relationship in their states - that is, while they might both have wave functions, when once of the pair resolves where it is, the other of the pair resolves itself as well to match it... even though no communication occurs between them. the second particle might never have been measured, and yet it's wave function still collapses when you measure the first particle. This is known as "quantum entanglement," or what Einstein famously referred to as "spooky action at a distance" because it happens faster then "c".

    You're missing the point.

    Richard Stallman *****HATED***** copyright. Hated it with a passion. He found the very concept repugnant. So, he wrote the GPL to essentially say "do whatever you want with this, just don't say you invented it from scratch and don't prevent anyone else from doing the same." The GPL is essentially about removing copyright restrictions, and preventing someone else from re-implementing them back onto the same body of work.

    So, while copyright law does in fact make the GPL enforceable, the whole pint of the GPL is to use copyright law to remove copyright. Hence why it's often called copyleft - compared to a normal copyright, it's kinda the logical opposite.

Much of the infrastructure and heritage stems from the people and events of the Revolutionary War (aka "War for American Independence") through World War II, heavily favoring the mid- to late-1800's. Operational topics before and after that (and during, to give meaning and context to the heritage) are taught in classroom settings. But though ADM Hopper's contributions to the field of computer science are important, at best it's the contributions that are taught (not the name), and definitely not in an operational context (she spent her entire career as a reservist and rarely was operational).

    Several other comments talk about a pair of particles being created out of nothing, one gets absorbed and the other flies away. This is basically right, but can be confusing (the one that gets absorbed has negative energy in order to conserve energy). Here's an easier mental model....

    Steve Hawking came up with an idea a while ago (70's perhaps?). He was thinking about black holes whose event horizon was around the size of an atom. Then he put it up against the Heizenberg Uncertainty Principle. He realized that particles in these black holes would have such a high degree of certainty about their position, that there would be such a low certainty about their velocity. Therefor, there would be some that would be REALLY fast. Not fast enough that they could escape the pull of the black hole, but fast enough that they could get just above the event horizon. There, they could give off a high-energy photon, and fall back in. This photon, since it was emitted outside the event horizon, would actually escape. This radiation can (and has been) detected, and causes what is known as evaporation. http://en.wikipedia.org/wiki/Hawking_radiation#Black_hole_evaporation

    Ironically, this means that smaller black holes (which have higher certainty about a particle's position) evaporate faster. Large-ish black holes absorb more energy cosmic microwave radiation than they emit in Hawking radiation, but if they have small enough mass (I believe smaller than the size of our moon), they emit more Hawking radiation than they receive from the cosmic background.
