    Your car keys have better range if you press them to your head, since your skull will act as an antenna. It sounds like some made up pseudoscience that would never work in practice or have a negligible effect, but it actually works.

    Edit: idk if it’s actually because your skull acts as an antenna, although that’s what I’ve heard. I looked it up and it seems like it’s your head acting as a reasonance chamber. Since your body is conductive, your head can bounce and amplify the radio signal.

      On one side you have people that think 5g causes cancer. On the other, you have people directly beaming shit into their skulls to open their cars from a couple extra feet away.

        i dont believe it causes cancer necessarily, but i think 5g is worrying for the sake of big increase in location tracking precision

        If you’ve ever played around with an old-style lighter (think classic Zippo) you’d get it! They’re fairly expensive, and aren’t airtight so they need to be refilled every few days/weeks. If you fill them too much they need to be kept upright or they’ll spill lighter fluid on you. Super cool and can hold flames for a while but not nearly as conventient as a matchbook for quick fire lighting

          It just occurred to me that zippos are basically the same type of oil lanterns that we’ve been using for thousands of years

    Oh, I have two good ones:

    1. Nuclear power causes less deaths (per energy unit produced) than wind (source)

    2. You get less radiation when living near a nuclear power plant, than if that nuclear plant hadn’t been there.

    To explain the second: A major misconception is, that nuclear power plants are dangerous due to their radiation. No they aren’t. The effect of radiation from the rocks in the ground and the surroundings is on average 50x more than what you get from the nuclear power plant and it’s fuel cells. (source). Our body is very well capable of dealing with the constant background radiation all the time (e.g. DNA repairs). Near a power plant, the massive amounts of isolation and concrete will inhibit any background radiation coming from rocks from that direction to you. This means, that you’ll actually get slightly less radiation, because the nuclear plant is there.

    Regarding the dangers of nuclear disasters. To this day, it’s been very hard to find out, if at all any people have even died to Fukushima radiation (ans not other sources such as tsunami/earthquake/etc.) Nuclear radiation causes much more problems by being an emotionally triggering viral meme spreading between people and hindering it’s productive use and by distracting from the ironic fact, that the coal burned in coal power plants spew much more radiation into the atmosphere than nuclear power plants themselves. (source)

      Nuclear power is actually the cleanest way to produce energy. The waste from replacing solar panels and windmills (which have a service life only three to five years) is actually more of a problem than the waste from spent fuel rods. Plus environmental impacts from fuel rod production are less than solar panel and windmill production. The problem with nuclear energy happens when things go wrong. It would have to be absolutely accident free. It never has been and never will be.

      Though they’re on the right track with nuclear power. Fusion would be ideal, runs on seawater (fuses deuterium/tritium) and if there’s a problem you simply shut off the fuel. Problem is insurmountable engineering issues, we just don’t have tech for it yet (need anti-gravity). They’ve been working on it for many decades and progress has been painfully slow.

    Oxford University is older than the Aztec empire.

      Wait, you’re saying that the Aztec empire was just 64 years old when Columbus discovered America and ships with conquistadors followed to butcher and enslave everyone?

          There were people there prior to the Aztec empire conquering them. The Aztec empire is just a specific government that ruled the area at that specific time.

          The Napoleonic empire, for comparison, only lasted 1804-1815 (with a hole in the middle).

    We might actually not know why magnets work.

    The formula used to prove the functionality of magnets can also be used to prove the existence of a theoretical state called a monopolar magnet - positive or negative on both sides. So either monopolar magnets can exist, even if in some esoteric circumstance, or we don’t know why magnets work.

        You realize that ChatGPT has no concept of “true”, right? It produces output which looks coherent and reasonable and tends to stumble into truthful statements on accident, by virtue of drawing from a dataset of people saying mostly true things. Of course, the bot is equally capable of spouting off outright lies in an equally convincing manner.

        This is a very unreliable way to verify a surprising fact. I strongly recommend against it.

            So does glass almost, glass is not a liquid, there are more than 5 stated of matter, a lot more, but glass is still a type of solid. It has some characteristics that recemble the characteristics of a really slow moving liquid.

            Well glaciers contain both solid and liquid parts. When you compress ice it turns to liquid. Water isn’t really easy to compress, liquid water can be lower than 0c (freezing), which is called super cooled, and it turns to ice when it’d not compressed anymore. You can make super cooled water or even soda at home, and if you give the bottle a shake it will turn to ice in a couple of seconds. Also the ground under the glacier will be moved together with the ice and water, there is do much force there. When a part of a glacier breaks off it’s called calving, like when a cow gives birth to a calf
