For example, Britain’s national mapping organisation’s brand is associated in our national consciousness with going to a small shop in a quaint village to get a map showing how to walk up a mountain. It’s called Ordnance Survey. If that sounds like Artillery Research to you, that’s because the project started because the king wanted to know how to accurately bomb Scotland.

    The USA drops approximately 15-20 million sterilized worms on Panama every day. Yes you read that right, it’s The Great American Worm Wall.

    Supply chains. It’s mindblowing how that patch of cabbage got to the produce section at your grocery store. Or how the parts of that gadget you bought at best buy were sourced, assembled, and shipped to the store. Some products that have multiple parts are shipped multiple times across countries, sometimes back and forth, as they get built and assembled by different factories.

      And some of those parts cost less than a penny to produce or even purchase when done in bulk!

    Our car centric world. We have somehow intersected everything and everywhere with death zone strips where people can’t go. And that’s entirely normal and accepted.

      Was kind of mind blowing moment when I was old enough to pay attention to the main underlying plot line of Who Framed Rodger Rabbit being about killing off public transport for cars. Like it is very clearly stated throughout the movie, but as a child it just went over my head. Not like I didn’t pay attention to when it was being talked about, just not able to appreciate the meaning. I also am from a more rural area, so things like public transportation were not something I interacted with outside of seeing it on TV shows and movies.

      Even weirder is that the most efficient way to steer them is not in straight lines. Because the most efficient way to traverse a sphere is on a slight curve.

      Get a string and pick two points along the equator on a globe. Stretch the string tight. It’ll bend into a slight curve above or below the equator (instead of following the equator directly) as you pull it, because the shortest distance between two points on a globe is not a straight line.

        of course the shortest distance is a straight line, that’s literally the definition of a straight line.

    4,000 years ago, we were doing trigonometry, but just 200 years ago we were still putting leeches on people and not washing our hands before doing surgery.

    Also, we sent people to the moon and got them back using less computing power than a smart watch.

      Those computers has less memory than a dollar store calculator. The bits in memory were physical magnets woven by hand into a mesh. It’s insane that it left our planet and came back with people alive.

    Driving.

    Somehow millions of us go hurtling by each other mere inches away in multiple tons of steel, often in conditions less than ideal yet for the most part, it’s a safe way to travel.

    We can’t even collectively agree on most topics, yet we put our lives in each others’ hands every day.

    Even disregarding all the other drivers, we put ourselves in a metal can, hurtle towards solid objects, and simply count on the idea that on average, nothing catastrophic will happen.

    Pure, random chance is enough to end us - animal pops into the road, a tree randomly falling, etc. - yet there we go, on yet another daily commute.

    I have a long commute through the “middle of nowhere” so lots of time to think about things that ought to be downright terrifying. The thought of hitting one moose is bad. Never occurred to me until just the other day that two moose was not out of the realm of possibility.

      Driving just gets more absurd the more you think about it.

      Had it not been invented yet, would anyone get away with suggesting a machine propelled by explosions supplied by a tank of the most flammable liquid possible kept underneath the passenger seats?

      Yeah, someone can do a lot of damage simply by ignoring the double yellow divider on a two-way highway.

    The sheer amount of information, feeling and emotional that happens to be conveyable by pressure waves in air. Can you imagine if sound just didn’t work? How much that would suck? It’s amazing that it’s like… a thing.

    Sight too (obviously, now that we’re thinking this way). But just how fucking weird can a thing be of you manage to think about it abstractly for a minute? Matter, over there, just so happens to excite a completely unrelated field that randomly permeates everywhere, even empty space(?!). And we went and fucking evolved little squishy organs that connect these intangible excitations in this weird field into the glob of electrical neurons that make our being. And by some complete fucking voodoo I’m sat here with a picture in my mind of all matter around me that’s emitting EM radiation in the 400 to 790 trillion wobbles per second range. That’s weeiird.

      And because everyone’s glob of neurons is independent from each other, we have no way of conclusively determining if everyone’s glob interprets things the same way.

      And yet on top of that, humans have worked out a way to send that information everywhere in a fraction of a second.
