For me it is the fact that our blood contains iron. I earlier used to believe the word stood for some ‘organic element’ since I couldn’t accept we had metal flowing through our supposed carbon-based bodies, till I realized that is where the taste and smell of blood comes from.

    There is about 8.1 billion people in the world. Assuming romantic cliches to be true and that we all have exactly one soulmate out there, we would have a very hard time sifting them out. If you were to use exactly one second at meeting a person it would take you 257 years to meet everyone alive on earth at this moment, which due to human life span being significantly shorter and the influx of new people makes the task essentially impossible without a spoonful of luck. Moral of the story: If you believe you have found your soul mate, be extra kind to them today.

      Soul mates are made, not found. You get with someone compatible to you, and through the sharing of experiences and affection, if nothing goes excessively wrong, they become unique for you.

    To piggy back on your “bizarre fact”, the same type of iron can be found added to cereal.

    I remember several times in school we’d do a science demonstration where we’d smash up Cheerio (or a knock off) brand ceral, mix the powder with water and slowly drag a magnet through the slurry. Every time the magnet would be pulled out of the mix, there’d be more and more tiny iron bits.

    Time relativity always boggles my brain, I accept the fact but I find crazy that if I strap my twin and his atomic clock to a rocket and send them out to the stratosphere at the speed of light, when they return he’ll be younger than me and his clock will be running behind mine. Crazy

    There are only 24 episodes of the initial run of The Jetsons and only 25 of Scooby Doo. They got aired as reruns for decades before more episodes were made. There are only 15 episodes of Mr. Bean.

      Every time that comes up, I think to myself “Something I’ve gone through must be more painful, right? I’ve gone through some pretty hellish things, and you’re trying to tell me something MORE painful exists? Not just a little more, but dramatically more? For my own sanity, I’m gonna have to live in denial of that.”

    Speaking as someone who grew up in the 1980s…

    Micro-SD cards almost don’t make sense to me. I’m not saying I don’t believe in them, because of course I have a few of them. Obviously they exist and they work. But. They’re the size of a fingernail and can hold billions of characters of data. I uwve a camera that ive put a 128 GB microSD card in. A quick tap on the calculator tells me that’s over 91,000 3.5" floppy disks. Assuming they’re 3mm thick, that’s a stack of disks 273 meters tall. But this card is so tiny that I have to be careful not to lose it.

        I remember my parents talking about some thing or other in star trek that would be impossible because you’d need “terabytes of storage, and that’s probably not possible”. And now you can go buy 1 tb of storage and lose it in your couch cushions.

    The birthday paradox

    If you get 23 people in a room the odds of two of them sharing a birthday are 50%

    The birthday paradox is a veridical paradox: it seems wrong at first glance but is, in fact, true. While it may seem surprising that only 23 individuals are required to reach a 50% probability of a shared birthday, this result is made more intuitive by considering that the birthday comparisons will be made between every possible pair of individuals. With 23 individuals, there are (23 × 22)/2 = 253 pairs to consider, far more than half the number of days in a year.

      it’s not part of the paradox, but there are also days when people tend to have more sex
      like new years, valentines, christmas etc. (in the west at least)
      so you tend to get more people born 9 months after those days

        In high school my graduating class was 38. The one before us was 21, the one after 18.

        Coincidently there was a massive blizzard that snowed everybody into their house for a week about 9 months before my birthday.

      Tides are a phenomenon where the height of the edge of a body of water shifts relative to the shore. A phenomenon is a thing. Why should explaining its cause in those terms have any effect on that?

          That’s like saying sunrise doesn’t exist because the sun is relatively stationary while the earth revolves on its axis. Sunrise and tides are the names we give to how we experience these things.

          Subjective experience cannot be wrong or right; it simply is. Interpretation of that experience can be wrong or right. Either way, the experience still happened.

    Queuing theory can have some fun surprises.

    Suppose a small bank has only one teller. Customers take an average of 10 minutes to serve and they arrive at the rate of 5.8 per hour. With only one teller, customers will have to wait nearly five hours on average before they are served. If you add a second teller the average wait becomes 3 minutes.

      I used to be like this, but with movies. When I first met my wife, she was utterly baffled at the concept of somebody not enjoying movies, and she made it her mission to make me enjoy them.

      Come to think of it, she actually doesn’t like music much. I’ve failed to change her opinion on that though because my taste in music is shit (and I’m proud of it.)

        I am still like this with movies and TV.

        It just doesn’t appeal to me. I’ve seen a handful of movies/shows that I’d call “not boring as shit” ever, and even then, its not something I’d choose to do myself, but is fine if I’m, like, chillin and chatting with people or whatever.

        Might be my neurodivergence, might also just be how much of a reader I am. Movies are just so slow compared to reading.

      I thought my significant other was one of these to a certain extent. It does weird things to me as a DJ. Turns out that she just likes the limited music that she likes and cannot stand most everything else.

        that just makes it easier to make a playlist with all their favorite songs.
