    They think not masturbating will give them anything from higher testosterone, better focus, or to a higher IQ.

    They think masturbation makes you weaker in every way.

    This is of course patently false, and all basically rises from an old athlete myth that sex during training will reduce your progress. Which these dorks then took to an extreme by saying any ejaculation will reduce progress in physical and mental training. Because we all know that the key to success is stored in the balls.



  • I remember doing the bear grills one, and one of the choices was to jump over a ravine, or walk over it using a fallen tree as a bridge.

    Being the hiker I am, the obvious choice of walk around it being missing kind of annoyed me, but I chose the tree option.

    Bear died.

    So I got to go back and pick the jump over option, which was apparently the right one.

    Who the fuck does running jumps over a 15 foot deep ravine.

    I never bothered with the choose your own adventure things again. When the correct choice is just not available and the next logical choice just means an instant loss, you don’t have a very fun game


  • If you’re a government, you can pretty much put anything in a rocket fairing and call it a reconnaissance satellite.

    The only warning that actually has to be given is that a rocket is being launched, so you don’t accidentally trigger WW3 by setting off launch detection satellites without warning. After it’s in space, no one can really tell what was in the fairing. Could be a spy satellite, could be navigation. Could just be a box with a bunch of little rockets in it, designed to slam into whatever you want at ridiculous speed.

    But it’s way more likely that this was just Boeing having a tiny leak in a propellant tank, or a bad thruster and as soon as the concentration of propellant and oxidizer got high enough, it triggered a detonation. They certainly have a history of not leak testing their shit: airplanes falling apart, space capsules with leaky thrusters, and now a blown up satellite point more towards incompetence than malice.





  • There was a big idea a couple decades ago that corporations were going to copyright natural genes and sell them for massive profits to other biotech companies that could use them to make cure for diseases and other things.

    Michael Crichton wrote a few books about it, pretty good reads.

    They did do the gene copyright thing in the real world, but it turns out that doing anything with a random gene is pretty hard and the genome isn’t just something you can copy paste a gene into and have it cure aids or cancer, so no one wanted to buy genetic sequences that they would then need to do a whole bunch of work on anyway to make it useful.

    Pretty much all 23andMe did was increase the size of the Law Enforcement dna database by letting cops send in samples of suspects and get back their family members info. Of course the company said that was very naughty, but no one got into real trouble for it. And now 23andMe owns a lot of other people’s genetic code, and it’s not worth the hard drives it’s stored on.



  • That’s kind of like saying that ford can’t make a model t anymore.

    I’m sure they could, there’s just no reason to.

    I’m also sure the contractors that built the Saturn V, those that are still in business, could build equivalent parts today if the government asked.

    The Saturn five was an absurdly large rocket designed specifically to get 3 people from earth to the moon. It was insanely expensive per launch, and the only reason it ever flew was because the government was writing nasa blank checks in order to beat the soviets.

    Today the government wants a reasonable dollar figure for a launch, and the days of spending a billion dollars per launch are long past.




  • Oh we have generics all over the place.

    The problem is that large drug companies abuse our patent systems to keep their drugs exclusive for longer than should be allowed.

    Look at EPI pens. The drug is just Adrenaline, you can get a vial of that anywhere as long as you have a prescription. But the EPI pen mechanism itself is patented. So no other manufacturer can sell an easy to use, pre measured dose of Adrenaline without violating the patent. That’s why EPI pens cost hundreds of dollars instead of the 20 bucks they probably actually cost to produce. And you need that mechanism, because no one with a throat that’s closing is going to be able to calmly pull out and ampule or vial, measure the right dose into a syringe, and get it into their system before they pass out from anaphylaxis.



  • To orbit the moon, a space craft needs to move at about 1.5 km/s, or 3300 miles per hour.

    So any landing starts with you going at 1.5 km/s and needs to end at the moons surface when you reach about 0 meters per second.

    If anything goes wrong with your engines while you slow down, you smack into the moon at either near orbital speeds, or at fighter jet speeds. The window for having an engine failure and being slow enough to survive is so narrow that it might as well not exist.

    That’s why Apollo used pressure fed, self igniting engines. As long as 2 valves opened, you had an engine. And Apollo landers had a totally separate ascent engine that worked exactly the same way, so if the landing engine failed, they could just drop the landing stage and return to orbit at practically any time during the descent. They even had a whole procedure of what to do if the ascent engine didn’t light when they were supposed to leave. Everything from jump starting the engine like a car with a dead battery, to physically getting access to the valves and manually opening them.

    I hate the current plan for Artemis. I hate that in 55 years, we’ve only managed to make shit more complicated. The current plan is for a vehicle with no abort capability to ignite its 3 turbo pumped, liquid methane fueled engines at least 4 times to get from low earth orbit to the moons surface, with days between ignitions.

    A capability that has never been shown to work or even exist in any capacity. Turbo pumps are finally machined pieces of engineering that need to behave exactly right, or they turn a rocket into either a bomb, or a giant tube that can’t move. And the current plan for Artemis calls for these finely crafted pieces of machinery to be subjected to the harsh environment of both space where they’ll sit for at least a week, and multiple ignitions, where they’re subjected to ridiculous temperatures and pressures.

    Absolutely ridiculous. We never left an astronaut on the moon in the 60s and 70s, but by god are they trying to open the first graveyard on the moon these days.
