    • I previously made this comment on the Patreon comments section, but suspect I did something wrong so I’m re-posting it here (more or less), mostly because it contain a major brag. 🙂

      A closed container (or one with only a small leak) of a liquid whose boiling point is below the external temperature can explode suddenly and with great energy when the liquid boils. This is called a Boiling Liquid Expanding Vapor Explosion, or BLEVE.

      The liquid can boil because the container is in a fire that heats the liquid above it’s boiling point. This is what often happens when tanker trucks or rail cars are involved in a crash or fire. The explosion is not caused by the flammable contents of the tank burning, though if the contents are flammable, it can make the results much more catastrophic. However, even water can explode this way. The Mythbuster’s launching a hot water heater through the roof of a house was a boiling water BLEVE.

      A BLEVE can also occur if the liquid’s boiling point is below normal room temperature and just heats up due to exposure to room-temperature air or water. This is what causes an uninsulated bottle of liquid nitrogen to explode, especially when it’s dropped in a bucket of water. (The water will warm up the nitrogen much more quickly than air would.)

      A strange case of a BLEVE is when the liquid in the tank is under great pressure. The pressure raises the boiling point of the liquid above surrounding temperature, so it won’t boil. However, if the tank springs a leak, the pressure will drop, and the boiling point will go down. When it drops below the external temperature, the liquid will boil and the tank will explode. I think this is what caused the high-pressure helium tanks to explode in both SpaceX Falcon 9 rocket explosions.

      If you look up BLEVE in Wikipedia, you’ll see my dad cited as one of the people who discovered and named the BLEVE. Woot!

    • I drove evolutionary psychologists so batty

      Don’t give yourself too much credit; they might have been batty before they encountered you.

    • There is a hint in that study:

      Instead of correlating to blindness, compare dick size to tendency to promote evopsych. With a sufficiently well prepared study, it should be possible to have a truly scientific result of “Men who indulge in evopsych have smaller erections and are lousy lovers”. With good enough publicity, maybe one could get those guys to STFU.

    • Where I struggle with this whole “more optimistic belief than reality” idea is I’ve encountered some of these conspiracy theorists and they don’t seem to be good people. They don’t seem to be all that concerned about sex trafficking because the next minute they gripe about #metoo and how there could be false accusations that cost men their jobs. Rather, it seems to be about taking down political opponents. (That said, I don’t understand what the objectives behind some of the “Deep State” conspiracies might be.) So, from my perspective, the idea that this is a “more optimistic belief than reality” rests on the assumption that the belief is sincere. I’m very sceptical of that.

    • Henlo, can we start a comment section here? I mean come on this is good material and there must be some pun I mean fun to discuss under it!

    • David Gross

      Really?

    • I realize this will be an unpopular opinion here, but here goes anyway. There is clearly a great deal of smoke surrounding the Epstein accusations, and we all know the old saw about smoke. Assuming what Rebacca says is true, I cannot fathom Krauss’s response to Epstein’s first trial.

      All that having been said, Epstein is not guilty of trafficking…yet. He has been convicted of solicitation of a minor, and he is currently under indictment for trafficking, but he has not been convicted. Trafficking and solicitation are distinct from each other. I don’t believe anyone clearly understands the reason(s) his first indictment resulted in a plea deal. I’ve read that the law at the time made a conviction for trafficking uncertain, and Federal prosecutors rarely go to court unless conviction is a certainty.

      So, perhaps the reason you are not hearing many scientists–who are supposed to withold judgment until they have all the facts–condemning Epstein for trafficking minors is because they are waiting for the outcome of the legal case. Accepting money from him is another question entirely. I suppose each person would have to make their own moral judgement on that one. If one believes Epstein benefited financially from his behavior involving minors and still accepted money from him, then that would certainly reflect poorly, to me at least.

      I realize this can sound like a crass attempt at playing semantics with sex involving minors, but that’s not my intent. There is a great deal of confusion among the general public when it comes to the term “trafficking.” Many of the highly publicized busts of “sex trafficking rings” have turned out not to be trafficking at all. The recent case involving Robert Kraft, for example, was touted by law enforcement officials as among the largest sex trafficking rings in history. Prosecutors have since stated publicly that they had no evidence of trafficking, and I believe some of the women that were initially called victims remain under indictment for prostitution.

      To be clear, I believe if Epstein is truly guilty of everything he’s been accused of then he deserves all the punishment allowed under the law–and then some. Indeed, his admission to solicitation of minors makes him a piece of shit in my mind. But trafficking is a far worse crime than what he’s been convicted of, and at this point he has not been convicted.

        Personally, I strongly feel that soliciting a minor for prostitution warrants condemnation. To be fair, I don’t know how many of the people mentioned in the article did condemn Epstein for that, but a) it was not enough for them to feel uncomfortable in his presence, and b) Krauss most certainly did not.

    • The Allies waged war against the Nazis not because of their violence to Jews, Roma, homosexuals, and others. They waged war against the Nazis because they invaded other countries.

    • Rebecca, what is your position? On the one one hand you say you’re not on board with beating Ngo (although throwing a milkshake is ok? Isn’t that assault?) then you suggest we might have avoided millions of Jewish deaths if we had only beaten up Nazis when it became clear what they stood for. Since you have made it clear you believe Ngo is a fascist (Nazi) then why wouldn’t it be ok to beat him up?

      You say Antifa’s body count is zero and compare that stat against fascists who are “murdering antifascists, Jews, Muslims, and women at an alarming rate.” Is that fair when “fascist” is such an arbitrary label? Antifa is visible, mainly because they mask themselves, while facists are…? Who decides who is fascist? Obviously you think Shermer isn’t able to identify one, so who is the authority?

      You want to prosecute people who commit violence? You want to confront VIOLENCE with violence? You stand next to me and I got your back. But as long as a person is not directly calling for violence against others, stating an opinion, no matter how idiotic, is not violence. The most inspirational, powerful, moving, and persuasive arguments in favor of freedom and human rights throughout history have often been responses to people expressing really bad ideas. Setting aside the question of who gets the privilege of determining which ideas are “wrong,” prohibiting people from expressing bad ideas denies everyone the right to hear the responses of those who disagree.
