    So, so many things wrong with this. First, you rupture the vacuum, you don't kill people. The train coasts to a stop, just like any other object traveling at 500 mph in the air (like, say, a passenger jet, except you don't have to worry about crashing into the ground because you're on the ground). The system is really just a high-speed train that operates in a vacuum for increased efficiency. Secondly, vacuum chambers tend to not be all that delicate. In fact, they tend to be made of incredibly tough material, because that's how you make a vacuum chamber. If you can swing a hammer strong enough to visibly dent half an inch of solid steel I'd be shocked (and it wouldn't lose vacuum due to a dent). Even if you punctured it with a rifle round (good luck with that), life isn't a Hollywood movie: the thing's not going to explode in a giant fireball, it's just going to (rather slowly) lose vacuum. Hell, they might not even notice right away: you need continuously running vacuum pumps to deal with leakage anyways, which will already be handling inflow on the level of a few mm sized hole. Now, if you hit it with an RPG, you might make a decent hole. Probably not, mind you: solid steel is no weakling. Your best bet would be C4, or maybe a bunch of thermite to cut the entire tube in half. That might actually kill people.

    Right. Using communication operated by the Russian SVR. That isn't normal, that's TREASON.

    Did you know, during the cold war, the US president had a communication line that connected directly to his USSR counterpart? And do you know who ran half that service? That's right, the KGB. And do you know why it wasn't treason? Because talking to foreign operatives isn't treason, it's communication. I mean, FFS, I'm no fan of Trump, but these kinds of rabid accusations really just add fuel to the alt-right fire.

    Let me put it another way: using a Russian-run communication line is generally a bad thing because it allows the Russians to hear what you're saying. But if the point of that communication line is to talk to the Russians, well, they kinda obviously already know what you're saying, now don't they?

  7. In this latest experiment, no photons or any other kind of particles were exchanged between emitter and receiver. So it really is quite different.

    That's not actually quite true. Photons are sent (and in fact photon counters are used to detect the signal). However, the information itself isn't encoded in the photons, it's encoded in the phase of the photons. The abstract uses the comparison to holography: in normal photography, only the amplitude of the light is relevant. In holography, the phase of a laser is used to encode information as well (specifically, the 3D depth of the target) in addition to the amplitude. This technique encodes all of the information into the phase alone, and none of it stays in the amplitude.

    TFA is, to put in bluntly, wrong. It claims

    It works based on the fact that, in the quantum world, all light particles can be fully described by wave functions, rather than as particles. So by embedding messages in light the researchers were able to transmit this message without ever directly sending a particle.

    But light is photons, and photons are light. You can't encode information in light without sending photons: it's like saying you talk to someone over the phone using words, but without using sound. It's just absurd. Of course, you can communicate over the phone using sound without using words, which is roughly analogous to what the scientists actually did.

  10. Re:Wow on Physicists Observe 'Negative Mass' (bbc.com) · · Score: 4, Informative

    Negative temperatures are actually a pretty well-defined and real thing, but that's just because of the way we define "temperature" in thermodynamics, which is not always exactly the same as what we think of as temperature in everyday life. The short explanation is that temperature (T) is the rate of change of energy (E) with respect to entropy (S) (in math: T=dE/dS). If I have a system that is bounded from above in energy (i.e. a maximum energy the system can reach), I can get negative temperatures. Simple example: let's say I have a system of particles, each of which can be in two states, a state with more energy, and a state with less energy. The entropy is the number of different states the *entire* system can be in, so if the system is in a minimum energy state (i.e. every particle is in the lower energy state) I have a minimum entropy system (every particle in the same state means I only have 1 possible state for the entire system). Likewise, in a *maximum* energy state, all the particles are also in the same state (the higher energy state), so I also have minimum entropy. Maximum entropy occurs when the energy is right in the middle between these: half the particles are in the higher energy state, half are in the lower energy state, so the entire system has the most possible configurations. So, if the system is in that state, and I add a bit of energy to it, I decrease the entropy (as there are fewer particles in the lower energy state and therefore fewer possible configurations). That means dE/dS is negative (since S goes down, so dS is negative, while dE is positive), so you get negative temperature.

    In every day life, systems typically aren't bound from above, and also any particles in higher energy states like that will fall into lower energy states and release energy (this is exactly how a laser works, incidentally), so you only get negative temperature in carefully constructed systems.

    The negative mass term in this case, however, is a negative effective mass (not a real mass) term that occurs in a group velocity (which is not the real velocity of particles in the system) dispersion relationship. Not to say the results aren't interesting: they are, they're just... well, not really negative mass at all.

    This sounds actually groundbreaking. Does anyone have more details? Were the authors trying to generate negative mass or was this an unexpected side effect? Obviously this is going to require some replication, but I'm excited.

    That's because the headline is some of the worst sensationalistic tabloid journalism level garbage I've ever read. They did not observe "negative mass". They created a system wherein, under specific circumstances, part of the system behaved as if it mathematically had negative mass. Note that the entire system and every part of it individually still has positive mass: however, because of the way the system interacts with itself, when you do very specific things to it, parts of it can act (when taking very specific behavior) as if they had negative mass.

    The headline and summary are the equivalent of saying "man travels through space safely without spacesuit on!", without mentioning he's inside a spaceship.

    That sounds awful, till you realize that from simple statistical fluctuation you'd expect that number to be 50 percent, in which light 63 percent seems to indicate some trend, but not nearly as big a one as the writer clearly intends to signify. How large is the average fluctuation? What's the probability women could have gotten such offers by chance (which would require knowing for e.g. the sample size, which, speaking of, that doesn't seem to be given in the report)? You know, anything that might reveal the statistical significance of the findings, which seem to be entirely absent from the report and without which raw numbers are almost entirely meaningless.

    with white women offered 4 percent less on average, and women more broadly offered up to 50 percent less in the most extreme examples.

    The report (linked in the article and here) says the average is 4% for all women. Also, "up to 50% in the most extreme examples" means "we found 1 case where that happened", which, again, you'd expect (in fact, you could probably find some extreme examples where a man was offered that much less than a woman), or at least, you'd *probably* expect (can't say for sure without knowing the variance of the job offers, which I supposed you could extract from the chart, but doesn't seem to be given in numerical form). 4% also just happens to be the average amount less women ask for than men. They also don't (AFAICT) look into issues like time taken off career for maternal leave (which, sorry, means you're going to be worth less due to not having been able to keep up with current developments, it sucks, but life choices have consequences), hours worked (statistically, men tend to work slightly longer hours than women: IIRC it's something like 8.4 vs 7.8 per day, but no clue if that is true in tech or not), etc. etc.

In point of fact, under federal law, an unborn child is recognized as a human if it is the victim of a violent crime. "The woman's choice" is completely irrelevant to the question, for the same reason a woman can't simply choose to kill a 6 month old, because everyone recognizes that a 6 month old is a human person, and one person cannot choose to kill another just because they feel like it.

It is, in fact, impossible to prove a negative, so asking people who say we're probably not in a simulation for evidence is literally asking for the impossible: it is always possible to say "well, the simulation must just be slightly better than any of our observations!"
