    ... You can't see black holes ...

    I should hope not, as that's the definition. However, we can see hot spinning gases that emit X-rays, we can measure how far across the hot spinning gas is, we can measure how fast the gas is spinning: therefore, we know the maximum volume, approximate mass, and minimum density of the object which the hot spinning gas is orbiting. That density shows that no such object is made out of ordinary matter like a star, and some are too dense to even be neutron stars. Are they black holes? Maybe. Most scientists think so, because we don't know of any other options, but if they dogmatically said "yes, those are definitely black holes", they wouldn't be scientists.

It's called beta-plus decay, or positron emission, and it's the basis of the medical PET (Positron Emission Tomography) scan. Antimatter protons are just slightly more exotic, but not by much.

    It's an interesting idea, but I think Approval and Range voting both do it better. (Approval: vote for every candidate who's "good enough", then add up the votes the same way as the current system. Range: vote each candidate on a scale, e.g. 0 to 99, add up the scores, divide by the number of voters.)

    I think your idea falls down in the two corner cases that any voting system ought to account for: third party candidates whom the voter doesn't know, and write-in candidates.

    Let's consider unknown third parties first. Suppose you look at the ballot, and you've got a good idea of how you're voting for the Democrats, Republicans, Libertarians, Greens, and so on. Then you see a candidate from, say, the Cheese Party. Huh? In your system, you can either vote for him (+1), or vote against him (-1). If you're like most people, you vote against him since you don't know if he'd be any good. You certainly won't vote for him. So even if the candidate was actually pretty sensible, the Cheese Party loses by a landslide, nobody ever looks into the Cheese Party, and the Cheese Party loses by a landslide in the next election, too. (Approval voting suffers from the same problem here.)

    Range voting lets voters leave a choice blank. "Blank" means "I don't have enough information to cast a vote, so I'll leave this choice to the more informed voters". (Very useful in states where you vote on judges, but judges' party affiliations are forbidden on the ballot, and there are so many races that it's impossible to research them all.) Now, Range Voting as normally implemented has a quorum requirement, so the Cheese Party still loses since few people had heard of them, but they score really well (among people who did vote for them), they make it into the newspaper, more people hear about the Cheese Party platform and what they stand for, and next time around more people give a score for their candidate. Maybe someday they win.

    Now, let's consider write-in candidates. Your system could either (A) forbid write-ins entirely, (B) automatically treat un-written-in ballots as "0", or (C) automatically treat un-written-in ballots as "-1". Assuming write-in candidates are a good thing, A is obviously a bad choice, and C results in the same problem mentioned previously for third parties. B, however, is even more dangerous: in your system, the final tallies for any winning candidate will almost always be small positive integers; even a small write-in campaign can completely topple the preferences of a much larger number of voters. We'll assume that C is the system actually used. (Approval is most similar to C.)

    Range voting, OTOH, can handle write-in candidates without blinking, since the system is already set up to gracefully handle "blank" votes on unknown candidates. If the write-in campaign is too small, they make a good showing but are disqualified by the quorum rule. If the write-in campaign is big enough, maybe they win. For a third party that's just starting out, being off the ballot isn't much different from being on the ballot, which means that all the petty politics of ballot qualification become irrelevant.

    Ranked Pairs is far and away the best option. It satisfies the monotonocity criterion. It is very simple to understand, especially from the perspective of a voter. You simply rank who you want to vote for. (Any voter who doesn't like it can simply rank their candidate #1 and leave the rest blank, just as we do now.)

    I was a huge fan of Schulze method (another Condorcet variant, and one used in the real world in Debian elections), until RangeVoting.org convinced me today that Favorite Betrayal is an actual problem in any Condorcet method. Not only does Range Voting not have this problem, it also bypasses a lot of the Arrow's Impossibility Theorem baggage (since Arrow only applies to ranked systems, not scored systems) and, even better, is nearly as simple as Plurality or Approval.

    (As the RV.org site points out, when you sit down and write code to implement a Condorcet method, any of them, you end up with about twice as much code compared to implementing RV. I've implemented Schulze voting before, so I know that of which they speak. Meanwhile, with RV, you just sum the votes as you would with Plurality or Approval, then divide by the number of voters. The fact that each vote is a ranged score rather than a {0|1} doesn't really change how the code works. Maybe you add a simple quorum check on the final score sums, but that's 2 lines of Perl using sort and grep.)

    Plus bee swarms use it to vote on new hive locations, so even though I was skeptical at first about the Bayesian regret metric, RV is a tried and tested voting method in the real world, and bees are considerably less intelligent than even the dumbest voter.

    There are two main problems with range voting. One, it makes voting overly complicated (not to the Slashdot crowd, but for the average voter.) Two, it is subject to gaming. Voters will be likely to rate secondary candidates lower than how they really feel in order to increase their top candidate's odds.

    Re #1: I'd argue that RV is actually simpler than any ranked ballot. Seven words: Hot or Not, Olympic scoring, IMDb, Netflix. Every Joe-on-the-Street already understands RV. It's one of the three simplest systems possible (after Approval and Plurality). Try out this Range Vote on the US Presidential race — unlike Condorcet, you don't have to stand around hemming and hawing about exactly which order you'd put them in, plus you can actually express "I have no opinion" by leaving a line blank. (And since they threw in all the kitchen sink candidates on that poll, you'll use that option a lot.)

    (In Condorcet, your only option for unknown candidates is to lump them all together in one big tie in the middle... but you're still saying "These unknown candidates are definitely worse than any of the ones I like" and "These unknown candidates are definitely better than any of the ones I hate". One of them could be {your undiscovered favorite|the reincarnation of Hitler}, but you've just {hurt|helped} their campaign. RV lets you leave them blank, so that better informed voters can put their knowledge to work — but thanks to the quorum, unknown bad candidates can't win by voting once for themselves or anything silly like that.)

Systems like the Condorcet Method, Meek's Algorithm and Range Voting have some theoretical advantages, but they fail in one crucial respect: they are hard to count. Range Voting creates possibly hundreds of rounds of counting. [...]

    Range Voting involves adding up a bunch of scores, then dividing by the number of votes cast to take the average. It's notionally simpler than IRV, only slightly more complicated than Plurality or Approval (there's one extra division at the end of the summation), it can use simpler voting machines than any ranked ballot system, plus the counting can be parallelized to individual districts (unlike IRV, in which all vote data must be physically located in one central location).

    Oh, and real-world IRV examples (like Australia) have clearly shown that IRV still creates a two-party system, because it's so heavily impacted by strategic voting that third parties are still shut out. If too many people vote honestly when their #1 preference is a third party, they risk the elimination of their established-party fallback and throw the election to whichever established party they hate the most. That's the exact "split vote" phenomenon that switching away from Plurality is supposed to solve.

    Whatever the solution is to two-party dominance, Australia has conclusively shown that IRV is not it.

    Despite being an atheist, it seems to me that "love thy neighbor as thyself" [Leviticus 19:18, repeated multiple times in the New Testament], rather than being something revealed only in the Bible, is writ large in the world itself, and pretty much all moral conduct flows from it. Love Thy Neighbor, the Golden Rule, Buddhism's Eightfold Path, Secular Humanism, and the winning strategy for Iterated Prisoner's Dilemma in Game Theory all point back to the same underlying basis for moral behavior.

Married ministers produce the occasional Bakker or Swaggart, but never the sort of sprawling, slow-motion train wreck of a scandal produced by celibate priests.

    The interesting part here is that the New Testament is quite clearly in favor of celibacy over marriage, which is why the Roman Catholic Church does it that way in the first place. Paul clearly states that "it is good for a man not to touch a woman" [1 Corinthians 7:1], and that sex of any sort, even in marriage, is a stain in God's eyes. However, because celibacy conflicts with human nature, even Paul acknowledged that marriage was an acceptable compromise to avoid the greater of two evils [1 Corinthians 7:7-9]. I'd say that the priest molestation scandal shows pretty conclusively exactly what he was talking about, and why a policy of celibate priests is a bad idea — probably why it was abandoned by Protestants a long time ago.

Are you saying that a single random mutation (or sequence of mutations on the same individual wasp) just happened to give the wasp the right venom for mind control and the instinct to sting a second time and attempt to lead the beast home for dinner? How do you subdivide that into valid evolutionary steps?

    Almost all venoms are chemicals that interact with either neurotransmitters or the receptors for those transmitters, and neurotransmitters are actually very similar to each other. Octopamine itself is very chemically similar to many other neurotransmitters, such as norepinephrine and dopamine. (They're all just a few -OH alcohol groups away from each other.) That similarity extends to activating each other — octopamine doesn't normally occur in humans, for instance, but it has a strong enough effect on the receptors we do have that it's occasionally abused as a party drug.

    Therefore, there are likely to be many venoms that seriously affect octopamine receptors purely by accident, ones that also target other receptors. So, it doesn't have to be a single mutation (or a single generation) at all. Each small mutation in the venom DNA would, if selected for, result in (a) a possibly-small improvement in blocking octopamine, (b) a possibly-small improvement in not blocking other signals, or (c) sometimes both of the previous at once. (The mutations that weren't selected for? Those wasps couldn't feed as many offspring, so those families died out.) Thousands of generations later, the result is a venom that's pretty specific to octopamine, resulting in a non-paralyzed but docile roach.

    With regards to the wasp leading the roach back to the nest: that's really no more shocking than any other case of complex instinctive behavior, like a baby fawn standing up and walking within 20 minutes of being born. The wasp's ancestors were dragging paralyzed roaches back to the nest millions of years ago, and tugging on an antenna isn't conceptually that much different. The wasp, to the extent that it thinks at all, probably still thinks of itself as "dragging" the roach; the wasp is merely pleasantly surprised at how little effort it takes.

    The second sting to the brain is something that could have evolved before (i.e. using the paralyzing venom, it improved the odds of the roach staying catatonic while being eaten by a wasp larva) or after (i.e. using the zombie venom, it improved the odds that the roach would become and remain obedient). There's really no requirement there on which order the two evolved in, since both are separate improvements, and it's quite easy to imagine possible evolutionary progressions (e.g. single sting => multiple careless stings => two stings for less wasted venom => one quick sting to subdue, one careful sting for good measure).

    (Oh, and the roach following the pull of the antenna? That's probably a built-in instinct in the roach. It doesn't want the antenna pulled off, after all. For most insects, the antennae are the most important sensory organs. It'd be like humans flinching when we see something flying at our eyes.)

    I don't really see how storing energy in a high density is inheritantly dangerous. It all depends on how you store it and then there isn't really any practical limit. Any battery will explode if a serious enough malfunction occurs, the question is what you consider "serious".

    It's really pretty simple. As a general rule of thumb, the smaller things are, the faster things happen. Bacteria duplicate themselves in 20 minutes, but elephant pregnancies last for 2 years. No amount of evolution will ever produce something elephant-sized that duplicates itself in 20 minutes, due to hard physical limitations. If you want to go faster, you must miniaturize, and conversely, if you do miniaturize, you will go faster.

    (That's why AMD and Intel are constantly falling over themselves to miniaturize their fabrication processes. Processors keep getting faster because their components keep getting smaller. There's a direct cause-and-effect relationship.)

    And now human beings want larger and larger amounts of energy confined into smaller and smaller batteries. Smaller, lighter batteries means, on average, faster rates of charging and discharging. And since 100% efficiency is physically impossible, faster rates of charging and discharging means faster rates of heat production. And since we're keeping the battery small and light, there's no room for massive heat sinks. All that extra heat stays concentrated in the battery, which makes the temperature much hotter.

    Now enter short circuits. These can be simple things like carrying a battery around in a pocket full of loose change, or more "exciting" ways such as crushing or puncturing the battery or breaking loose something internal. In any case, a battery experiencing a short circuit will (by definition) discharge at the maximum possible rate — and thus produce the highest possible temperature. Even if the battery itself doesn't catch on fire or explode, even older NiCd and NiMH batteries get hot enough to cause serious burns if they're near flesh when they go off, and it's quite easy to set nearby combustible materials like paper on fire.

    You can reduce the impact of short circuits by increasing the battery's internal resistance, which will slow down the maximum discharge rate. However, this also slows down the maximum charge rate, and human beings want their batteries to be fully charged right now. Humans don't want a battery that will run their laptop for 2 days but takes 2 days to charge, which is what you get if you slow down the battery all the way to the minimum useful discharge rate. (It also reduces battery life, since it converts more energy to heat during normal operation, and also takes up space that could've gone to more battery capacity.)

    There's simply an unavoidable conflict sitting plain as day in the laws of physics, and no new battery design will ever solve it. Human beings want safe, fast-charging, high-density batteries. Pick two.

    Side note: Neonatal mortality isn't really a fair basis for comparison, since there's no international standard on how premature births are treated. In many countries, if a baby is born prematurely and dies shortly thereafter despite medical intervention, it's counted as a stillbirth, miscarriage, or the like. In the US, the same baby gets tallied as a neonatal death.

    From what I understand, the evidence is also pretty strongly in favor of a pandemic fungal infection that weakens the hive's ability to overwinter. That's another strike against the GM crop silliness.

    Folks, if you're going to oppose GM crops, do it for the right reasons: Monsanto is a company of fucking douchebags, genes shouldn't be patentable, and GM crops are almost always monocultures derived from a single modified plant.

    The reality is that most of the genes people want to add to GM crops are a selective disadvantage in the wild. Plants don't spray Roundup on each other in the wild, so all the effort spent making a plant glyphosate-resistant is wasted energy that could have gone into something productive. Likewise for golden rice (the rice doesn't need the Vitamin A, after all) and just about anything else humans would care to add to a crop.
