    I didn’t make clear, that I mean using something for measuring really large distances, like the length and width of a large building’s base. A typical measure stick would have less stretching than rope, sure, but would also be tedious to measure with. Counting the spins of a wheel as you roll it is trivially easy and quick in comparison. Wood warps, but not really that much.

    The spoke of the wheel is the same length used to measure the blocks. Other comments here have gone into detail. If the height of the blocks is the same as the diameter or radius of the wheel used to measure the base, then the relations will always be some function of pi. You don’t have to know any definition of pi for this to always be geometrically true.

    Wheels are always a fraction of pi. Whether you like it or not. Lengths of string can be arbitrary, but a circle’s dimensions are always tightly related to and proportional to pi in some way. I also recall that wheel measurements are more precise for large scale building because, unlike rope, leather and cloth, a wooden wheel doesnt stretch. Two wheels made similar will stay more between a much tighter error factor than two pieces of rope. The rope might start at the same length but will deform differently as they are used.

    We used purpose made floor pedals on the sociology research office to control a transcription software. It allowed precise control over a voice recording so any of us lowly students could quickly transcribe interviews and focus groups without removing the hands from the home row of the keyboard. It was already 30 years old technology by the time I got to college. It was apparently first invented for work with actual tape players.

    Virality cannot be planned for and, for the most part, none of these moments went viral. Most people in the world didn’t knew about the mission, a ton more aren’t even aware it happened. These kinds of moments aren’t “allowed” to happen, they just happen because humans are humans. NASA, and scientists in general, are not at all a bunch of stiff book worms like the stereotypes dictate. People are people and will make jokes and try to keep work environments light. There’s enough stress on trying to fulfill the mission and come back alive already.

    They were also super busy though, this mission was a test flight and, well, they spent most of their wake time doing science and testing the spacecraft. Not much time for PR stunts and goofing off, really.

    Patients lying about symptoms have been a medical issue for centuries. It is the main topic of Baudrillard’s philosophical analysis on simulacra and simulation. Think about it, a soldier who doesnt want to be deployed starts simulating symptoms of a disease to be discharged. How would you catch him, can you? The answer seems straight forward, until you scrutinize it in detail. Neither military or medical knowledge actually have an answer. The kid who doesn’t want to go to school says he has a headache and a tummy ache. How do you validate another’s conscious and sensory experience? Hypochondriacs affirm to develop every disease they hear about. People under stress feel and have somatic symptoms akin to physical diseases, even when functionally nothing is wrong with them. Etcetera. Disease and diagnosis are not so simple and straight forward, not even when talking about bodily functions.


  • That’s mostly irrelevant because Apollo didn’t have computers landing the ships. They were humans. Astronauts trained hard to achieve that. Computers only flew the initial takeoff and ascent. An IBM computer that stayed behind with the rocket. But Armstrong landed that bird on the moon by hand.

    Also, while the on board computer allowed them to consolidate sensor input, and calculate and execute burn maneuvers (relatively easy tasks), everything was double and triple checked by mission control back on earth. With way more powerful, faster and capable computers. Anything that required reflexes or finesse was done by a human hand on a joystick.

    This is why all those attempts are impressive even if ultimately failed some way or the other. Because they are autonomous landers. A technology that didn’t exist until the turn of the millennium.




  • Not to you, although I would bet it has done so to someone. The main issue is though, if you asked an LLM to write arguments for a flat earth, it would do so. Convincingly and insistent, without even questioning or critically analyzing why. Ask it to compare and balance arguments both ways. And it will do so as if both positions were equally real and valid.

    It has no notion of reality and no convictions of its own.

    It will also hallucinate fake papers and quote people that don’t exists to make its argument.

    PS: most poignantly, the point of the paper is that it says, over and over, “this information is false, this disease doesnt exist. All of this is made up”. Unlike the other problematic papers quoted on this comment thread that were published with conviction by the authors, and later were retracted. Yet the LLM is unable to parse that tidbit of information. It is not as smart as the most stupid. It simply is not intelligent, not even as intelligent as the most stupid humans. You can tell it, the following sentence is false, and it is not smart enough to pick up on that meaning.



  • Veto power is supposed to represent nuclear power. The logic is that it is way better for a country to veto a resolution than it bombing another country because they got pissy.

    I always remind people that the UN’s mission is not to solve all the world’s problems, but to stop countries from tearing each other apart and avoiding all out nuclear mutual annihilation. So far, it has succeeded.

    I also hate that it has no teeth against modern issues, like genocides of non nation state peoples. But genocide didn’t even exist as a concept when it was created. The concept was coined by a Jewish legalist who scaped the holocaust.

    BTW, same dude hated the guts of Zionist israel and warned that an ethnostate would lead to genocide eventually. He was 100% right.


  • Gee I wonder what would it take to solve world hunger. Maybe a comprehensive strategic plan that changes minds of decision makers and pressures them through diplomacy and negotiations. Perhaps we could pool resources at the same time to distribute food to the countries most affected by sitemic historical injustice. Someone should manage that complex of a problem. Maybe a neutral governing body that ensures it’s well managed and countries pay something up front towards this problem. We should call it the league of countries against hunger, or the coalition of groups of people. I don’t know, I’m bad at naming things.



  • That was always so frustrating and annoying to me. “We won’t invest money on nuclear power because someone in 10,000 years might get radiation poisoning from the waste we will carefully bury underground. So, let’s keep burning coal, pump the waste smoke into the air that will kill the atmosphere whitin three decades and give everyone radioactive poisoning, today!”

    Humanity was handed the key to stop global warming dead in its tracks and skip straight to renewables with a healthy planet. But we can’t seem to resist the temptation of blowing people up for a slightly higher profit next quarter.
