    Here’s a fun one

    You know how you go to the public pool and you smell the chlorine keeping the water clean? That’s not chlorine you’re smelling.

    Chlorine is a great sanitizer but when dissolved in water it has almost no smell. However, chlorine binds to organic substances like dead skin cells and especially strongly to urea (aka pee), forming chloramine. Chloramine has significantly less sanitizing capability than chlorine, but it has a very strong chloriney smell.

    You can get rid of chloramine by ‘shocking’ the pool- adding an oxidizer or increasing the chlorine level very high to what’s called breakpoint chlorination. Shock powder is expensive though so it’s not always used as often as it should be.

    So when you go to the public pool and you get that strong chlorine smell, all that means is either the pool water is dirty and hasn’t been shocked in a while, or someone peed in the pool recently.

    Enjoy your swim!

        The chlorine does its job, and whatever shit it kills becomes chloramine. Chlorine does have a smaller smell of its own so maybe they just put a shit ton of it in also.

    On average, there are more fecal bacteria on your phone screen than on a public toilet seat.
    Also, when you flush the toilet after taking a shit, fecal material will get sprayed on literally every surface in the bathroom.

    I don’t think I’m ever going to forget, I went on a road trip and when I was in Arizona stopped at a rest stop and took a leak and washed my hands afterwards.

    This native guy walked in, and I only call him out for being native because I’m native also so it’s kind of cool to see another one in the wild, and he immediately said, “Get some poop on your hands? I only wash my hands when I get poop on them.”

    Neuroscience shows that rulers will always become evil.

    Getting more power actually changes your brain, suppressing your ability to use empathy. The very powerful will always struggle to remember that others are human and don’t want to be hurt.

    Humane behavior and hierarchy are mutually exclusive. Heirarchical organization encourages humans to hurt each other.

      The data is skewed. All of the functioning systems we use reward concentrations of power.

      Thereby, systems of rule must distribute power and contest the concentration of power. It literally takes a village to save us from ourselves.

        The fact that power results in antisocial behavior has been understood for millenia.

        Lots of societies have had cultural infrastructure of equality that attempts to mitigate this weakness in our biology and prevent harmful levels of power accumulation. The basque village layouts that Davids Graeber & Wengrove talk about, or the practise of ‘insulting the meat’ of successful hunters.

          Which is why I feel that for humanity to succeed we will eventually need an entirely new form of societal governance to replace capitalism & communism, just as those systems replaced feudalism and tribalism. Something like technoism where decisions are made and enacted by machines, incapable of self motivation; or geneticism where leaders’ selfish impulses are either bred or edited out of them. We are still many, many years off from technology being able to accomplish this, but the only way to overcome the human factor is to… well… remove the human factor.

      I think part of it is that when good people gain power they realize that they have also taken on responsibility. And when you are shouldering a lot of responsibility, and the people around you are not, it’s easy to see them as childish or selfish, or not thinking things through thoroughly (because let’s face it: they’re not).

      Plus as a responsible party you have to be responsible for everyone and this can mean limiting your beholden-ness to any one party. That can look like distancing or lack of empathy for that person. “Oh now that you have power you’re too big for me, huh?” Pretty much yes, actually.

      If you’ve ever been in charge of something you know what I’m saying. And when I see people blindly bitching about people in power I know they’ve never been responsible for anything bigger than a shopping cart.

        It’s not a question of “look[ing] like distancing or lack of empathy”, or just “bitching about people in power”.

        Scientific studies that look at your brain itself - not your behavior - show that as people get more power the brain’s empathy centers become suppressed and you are chemically less capable of being a good person.

    If a nuclear missile is launched at the United States the President has just 6 minutes to come to terms with that and decide to launch a counter attack or not.

    If that counter attack is headed to North Korea, any land based missiles will head over the arctic circle, over Russian airspace where similar shoot/no shoot decisions will have to be made in a similar timeframe.

      If a nuclear missile is launched at the United States the President has just 6 minutes to come to terms with that and decide to launch a counter attack or not.

      US nuclear deterrence in 2024 doesn’t rely on launch-on-warning, but on the expectation that no hostile power has the ability to locate and destroy the US ballistic missile submarine fleet prior to them performing their counterlaunches.

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

      In nuclear strategy, a retaliatory strike or second-strike capability is a country’s assured ability to respond to a nuclear attack with powerful nuclear retaliation against the attacker. To have such an ability (and to convince an opponent of its viability) is considered vital in nuclear deterrence, as otherwise the other side might attempt to try to win a nuclear war in one massive first strike against its opponent’s own nuclear forces.

      Submarine-launched ballistic missiles are the traditional, but very expensive, method of providing a second strike capability, though they need to be supported by a reliable method of identifying who the attacker is.

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

      Launch on warning (LOW), or fire on warning, is a strategy of nuclear weapon retaliation where a retaliatory strike is launched upon warning of enemy nuclear attack and while its missiles are still in the air, before detonation occurs.

      In 1997, a US official stated that the US had the technical capability for launch on warning but did not intend to use a launch on warning posture and that the position had not changed in the 1997 presidential decision directive on nuclear weapon doctrine.

      This non-reliance on launch-on-warning is also true of the French and British nuclear deterrents – the British don’t even maintain a nuclear arsenal other than on subs, so they haven’t even bothered with maintaining the option to do so, and the French only use tactical ALCMs in addition to the strategic sub-launched weapons; those weapons probably would be poorly-suited for such a role.

      The Brits rather famously have the “letter of last resort”.

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

      The letters of last resort are four identically worded handwritten letters from the prime minister of the United Kingdom to the commanding officers of the four British ballistic missile submarines and stored on board of each. They contain orders on what action to take if an enemy nuclear strike has both destroyed the British government and has also killed or otherwise incapacitated both the prime minister and their designated “second person” of responsibility, typically a high-ranking member of the Cabinet such as the deputy prime minister or the first secretary of state. If the orders are carried out, the action taken could be the last official act of His Majesty’s Government.

      If the letters are not used during the term of the prime minister who wrote them, they are destroyed unopened after that person leaves office, so that their content remains unknown to anyone except the issuer.

      Process

      A new prime minister writes a set of letters immediately after taking office and being told by the Chief of the Defence Staff “precisely what damage a Trident missile could cause”. The documents are then delivered to the submarines in sealed envelopes, and the previous prime minister’s letters are destroyed without being opened.

      In the event of the deaths of both the prime minister and the designated alternative decision-maker as a result of a nuclear strike, the commander(s) of any nuclear submarine(s) on patrol at the time would use a series of checks to ascertain whether the letters of last resort must be opened.

      According to Peter Hennessy’s book The Secret State: Whitehall and the Cold War, the process by which a Vanguard-class submarine commander would determine if the British government continues to function includes, amongst other checks, establishing whether BBC Radio 4 continues broadcasting.

      In 1983, the procedure for Polaris submarines was to open the envelopes if there was an evident nuclear attack, or if all UK naval broadcasts had ceased for four hours.

      Options

      While the contents of these letters are secret, according to the December 2008 BBC Radio 4 documentary The Human Button, there were four known options given to the prime minister to include in the letters. The prime minister might instruct the submarine commander to:

      • retaliate with nuclear weapons;

      • not retaliate;

      • use their own judgement; or,

      • place the submarine under an allied country’s command, if possible. The documentary mentions Australia and the United States.

      The Guardian reported in 2016 that the options are said to include: “Put yourself under the command of the United States, if it is still there”, “Go to Australia”, “Retaliate”, or “Use your own judgement”. The actual option chosen remains known only to the writer of the letter.

      This theory was around long before Lee Cuixin and done much better. Saberhagen’s Berserker series is a much better example, and has the added bonus of believable character development in his books.

      Hell, Battlestar Galactica was the same thing done 5 years before TBP came out, and way more interestingly.

        I’d read that David Brin reviewed something similar in '83, but I didn’t chase it down to Saberhagen.

        In following the links provided in the Wiki article, for the Berserker Hypothesis, there is the following:

        The Berserker hypothesis is distinct from the dark forest hypothesis in that under the latter, many alien civilizations could still exist provided they keep silent. The dark forest hypothesis can be viewed as a special case of the Berserker hypothesis, if the ‘deadly Berserker probes’ are (e.g. due to resource scarcity) only sent to star systems that show signs of intelligent life.

        So, silence is survival in the Dark Forest. The Berserker Hypothesis seeks and destroys.

        e: Nice call on BSG as well! Though, that considered only human and Cylon life.

        And, for my part, Cixin Liu’s second book was a really solid read. The first book, Three Body Problem, suffered all of the hallmarks of the pains taken to establish a story and a world. The last book, Death’s End, while mostly good, also suffered in needing to bring the grand story to a close.

          We’re going to have to disagree on those books. I found the first one amateurish and hand-wavy SF with terrible character development, and the second one was just a ridiculous deus-ex-machina plot point that invalidated all the rest of the previous and possible future plot pivot points, with continued terrible character development. I wouldn’t know about the third, by this point I was done giving him any more of my money.

          I’m surprised about Brin’s article there, because all his work has been pretty upbeat about galactic species generally getting along, though with its rough points.

          Personally, I chalk up the great silence to very short species lifespans after achieving spaceflight. Maybe they all go post-singularity and become undetectable, or run out of resources and go primitive again. Or just die off/suicide, which seems like where we’re headed. If we have a century of relatively powerful transmissions, what’s the chance of anyone being close enough in that short period of time to detect us?

            I guess we are going to have to disagree. The writing style and, as I perceived it, motivations within the text were clearly not of the Western tradition. It’s true, in lending the benefit of doubt, I may have enjoyed it more precisely because I disregarded standard writing mores, tropes, and conventions because it was a translated work.

            I’m curious: Did you also try Murakami’s 1Q84? I found that I had to suspend expectations there in much the same manner.

            I think I’d agree with you wrt. short species lifespans after developing telecommunications, space flight, and highly concentrated energy sources. The leap in capacity for attendant social distortion — and extortion — has brought us to the brink of global destruction many times since Signal Hill in 1901. The Kardashev Scale comes to mind here. The leap from about Type 0.73, ostensibly where we are now, to Type 1.0 is fraught.

            As for the communications we have sent, the early ones were low-power and, over a distance of 100 ly, would significantly degrade against background EM radiation. At a range of 50 ly, where our first, more powerful and higher fidelity digital transmissions have reached, there are relatively few star systems — about 1300 (source). This source uses data from 1991, so there may be more, but not many, that are magnitude 6.5 or brighter.

              1Q84: never ran across it, but from the wikipedia article:

              novel’s excessive repetition, clichéd writing, clumsy styling and unyielding plot.

              Which is pretty much where I was with TBP, so I can’t imagine I’ll rush out to read this.

              Regarding translation: https://www.reddit.com/r/books/comments/s3zm9t/the_threebody_problem_is_not_good/izxm5l2/

              I’ve read other chinese authors translated by the likes of Ken Liu and I see nothing like that, enjoy them well enough, before and after reading TBP. So the usual “your closed western mind can’t conceive of the Chinese style” argument kinda pisses me off when I get it back in discussions of these books. But I’m used to that reaction, so I don’t take it personally anymore.

              Yah, I was thinking of the attenuation issue there, and not to mention that eventually the powerful transmissions go away in order to use low-power, high-bandwidth satellite bouncing instead of blaring away at 1kW to communicate. I imagine we’re already much quieter than we were 20 years ago.

                No accusation intended. Related my experience and seeking yours. Thanks for sharing what you have read about it.

                Then, help me out if you feel inclined. Point me in the direction of some solid sci-fi, written in another language, with good translation to English. I’m always looking for the next read. I could Google it. But, instead, I’m looking for a recommendation from a strong critical eye. As guidance, I’m a pretty big fan of space epics, political intrigue, and/or social

                Also, thanks for the language on attenuation. I’ve done a bit more reading on it, and I’ve seen the math. What I’ve learned is that most regulated radio transmissions in the Western hemisphere are capped at 50 kW. There are several transmitters that are in the 150 kW range, and, back in the 30s, there was that one titanic tower in Florida that kicked out 500 000 kW.

    There are about 20 supervolcanoes on earth which each have the capacity to kill billions should they erupt.

    Heres two:

    The ratio between cells of your body that belong to you vs. cells on or in your body that are microorganisms is about 1:1 — slightly favouring the bacteria.

    If the Sun were destroyed, we would not know about it until more than 8 minutes after it happened.

      I claim ownership of the microorganisms in and on my body. I am not merely human; I am a glorious amalgamation of trillions of distinct beings, working in harmony to bring you shitposts!

    At birth there are usually more males than females. Around adulthood age they are roughly equal, and around our death there are way more females than males.

    Another one, kinda romantic as well. Most life long couples, when one of them dies due to old age, the other one follows soon. Despite women having a longer life span than men.

    Another interesting one, most relationships end within 7 years. Once the 7 year period has passed, the likelihood of that relationship lasting till death increases significantly. It’s called 7 year ick.
