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.

Homelessness. But I don't occasionally think about it. I see it every day. In the richest nation in recorded history.

That milk forms such a big part of western diets considering where it comes from.

[–] Cysioland@lemmygrad.ml 1 points 1 hour ago

it's the lactose tolerance pyramid scheme

Yeah dude the more I think of milk as sexual assault the stranger it feels.

[–] MrsDoyle@sh.itjust.works 2 points 19 minutes ago

In the staff fridge at work someone used to label their milk as "breast milk" and people would go eeeww. Like it was snot or something. But from a cow's breasts? Fine! So weird.

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.

This is wild. Good share!

This seems like it would make for a good Wikipedia article, but am I could find was this section:

[–] QueenFern@lemmy.world 8 points 16 hours ago

I just looked this up because I didn't believe you, but you aren't spinnin' tales, my friend. This is true, and it's blowing my mind. Thank you for sharing this fact!

[–] scytale@lemm.ee 46 points 19 hours ago (1 children)

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.

[–] jqubed@lemmy.world 13 points 17 hours ago (1 children)

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

[–] FrostyCaveman@lemm.ee 3 points 9 hours ago

Scale. That’s the one thing I can’t get my head around

[–] GregorGizeh@lemmy.zip 48 points 19 hours ago (2 children)

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.

[–] bradboimler@lemmy.world 3 points 1 hour ago

I'm fortunate enough to live in a walkable neighborhood. When I moved here walkability didn't really factor in; I have friends here and I liked the apartment.

Man, it is so nice. I definitely appreciate it now and will try to factor it in in the future. I am absolutely convinced that walkability fosters community and cars reinforce social isolation.

I still have my car but I consider it and driving a burden. If I had to replace it I'm pretty sure I wouldn't.

[–] dRLY@lemmy.ml 19 points 17 hours ago (1 children)

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.

[–] Lettuceeatlettuce@lemmy.ml 54 points 20 hours ago (2 children)

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.

[–] kayazere@feddit.nl 17 points 10 hours ago

It’s insane how wasteful modern software is. The infinite growth mindset causes companies to pack more useless features into software and load it up with spyware and adware.

Google and Facebook’s tracking and ad software are a big cause of computing waste in most websites and mobile apps.

[–] otacon239@lemmy.world 29 points 19 hours ago* (last edited 19 hours ago) (2 children)

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.

[–] Cysioland@lemmygrad.ml 1 points 1 hour ago

to be fair, most of the calculations were done on Earth

[–] PM_Your_Nudes_Please@lemmy.world 10 points 17 hours ago

Yeah, they even employed weavers to make the memory units, because it was easier than training factory workers to deal with such thin wire.

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.

[–] Knock_Knock_Lemmy_In@lemmy.world 4 points 12 hours ago

What if we were able do to travel around in a robot suit that we could fully control. Oh yeah, thats a car.

[–] manicdave@feddit.uk 30 points 20 hours ago* (last edited 20 hours ago) (4 children)

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?

[–] thezeesystem@lemmy.blahaj.zone 4 points 11 hours ago

Reminds me of the Asgard from Stargate and how there advanced race was surprised about how we us explosives to propel a bullet and "primitive" things they never really thought of or considered because there dangerous.

[–] Scrath@lemmy.dbzer0.com 5 points 13 hours ago

Your comment just reminded me of a sci-fi short story about how humans solve every problem eith explosions.

[–] LeftRedditOnJul1@lemmy.world 19 points 20 hours ago (1 children)

If you think driving's weird, think about flying, too. We put several tons of that explode-y liquid, along with a bunch of people, into a big metal tube and shoot it into the sky. And we made that form of transportation several orders of magnitude safer than driving.

[–] Catoblepas@lemmy.blahaj.zone 11 points 20 hours ago (1 children)

I feel like it’s probably going to go down in safety an order of magnitude or two in the US given, you know, The Horrors.

[–] skulblaka@sh.itjust.works 1 points 3 hours ago

The aviation industry can absorb a whole lot of sin before they're on equal danger footing with automotive, if for no other reason than sheer volume. Most people, unless you fly constantly for work, get on a plane once a year or less. Most people drive to work almost every day. Roads have traffic, the skies do not (at least, not nearly to the same extent, midair collisions can happen but they're rare).

I have no doubt the skies are about to become noticeably less safe, but they've got a looooot of catching up to do before they dethrone the automobile as one of the top 3 leading causes of death in America.

[–] ADKSilence@kbin.earth 13 points 20 hours ago (1 children)

Not just merely a machine powered by explosions, sitting on volatile liquids... but one in which we've decided that it's also a great place to enjoy some music, maybe a nice beverage, and as a great way to take our attention off into vast distances to the sides to "see the sights".

I think to myself as I steer with one knee, trying to simultaneously drink my coffee and light a cigarette...

[–] manicdave@feddit.uk 17 points 20 hours ago (1 children)

You don't need to worry about crashing. You'll be protected by an unmaintained bomb that can inflate a pillow faster than you can travel 18 inches at 70 mph yet somehow never goes off accidentally.

Last I heard we're still in contact with Voyager 1

[–] Cysioland@lemmygrad.ml 1 points 1 hour ago

Voyager 1 is the antithesis of planned obsolescence¹, with it long outlasting its mission

¹the real kind, no the meme kind liberals often say that things are the result of

[–] Lettuceeatlettuce@lemmy.ml 2 points 7 hours ago

So amazing, the amount of incredible science we've been able to do with the Voyager program.

[–] theywilleatthestars@lemmy.world 12 points 17 hours ago (2 children)

Airplanes. Like I get that we can make them stay up, but we can steer them?? Across entire continents and oceans? What the entire fuck

[–] INHALE_VEGETABLES@aussie.zone 7 points 16 hours ago

They are made of steel, lmao... how silly do they think we are.

[–] PM_Your_Nudes_Please@lemmy.world 4 points 17 hours ago* (last edited 17 hours ago) (2 children)

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.

[–] pebbles@sh.itjust.works 1 points 2 hours ago

Has anyone ever sent you nudes cause of your name?

[–] juliebean@lemm.ee 5 points 14 hours ago (1 children)

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

[–] PM_Your_Nudes_Please@lemmy.world 4 points 8 hours ago (1 children)

The point is that you can’t follow a straight line on a globe, because that’s longer than taking a slight curve. If you take a straight line, you follow the entire circumference of the earth, but following a curved path allows you to avoid some of the width. Basically, the circumference means a straight line is more curved than a curved path.

[–] asret@lemmy.zip 1 points 2 hours ago

Isn't it still a straight line from the perspective of someone travelling it? It just appears curved because you're looking at it from outside the curved surface.

The sheer amount of information, feeling and emotions 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 if 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.

[–] AngryCommieKender@lemmy.world 1 points 1 hour ago (1 children)

Alternatively, if sound worked in a vacuum, the way light does, The Sun would be the loudest thing in the solar system.

I'm pretty sure in that case the sound alone would kill us..

[–] Tower@lemm.ee 2 points 17 hours ago (1 children)

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.

Really makes me wonder what cybernetics will look like in a hundred, a thousand(!) years. No-one can experience someone else's consciousness. But if an artificial brain extension generated consciousness the same way we do and if it could be swapped between people safely. It might be the first time we have something saying, objectively, it has experienced being both of us in each of our brains and we see "red" the same way. The mind boggles...

[–] manicdave@feddit.uk 3 points 20 hours ago (1 children)

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

[–] FourPacketsOfPeanuts@lemmy.world 4 points 4 hours ago* (last edited 2 hours ago)

Lightning trapped in sand etc. I used to play a kids game called Turing Tumble which shows how all logic operations can be replicated with little plastic seesaws and marbles. If you put the bits of plastic on the board in the right way you can see marbles falling by gravity performing binary addition. It blows my mind that that's all that's going on in my PC, just a trillion times the scale. I've worked in IT all my life and it continually surprises me that any of this stuff even works.
