13 Incredible Inventions That Changed the World

[@Prospector32]

I'm not sure if it was used elsewhere but in Nova Scotia, Canada, before the pizza saver was invented, they used to put a little bit of dough in the center of the pizza to do the exact same thing. We called it a pizza bun and we always fought over who would get it. Our local pizza joint has reverted to the pizza bun in the last few years because they wanted to be more environmentally friendly. It's one fewer disposable plastic items in the world. If you care about that kind of thing, maybe everyone can pressure their own pizza restaurants to do the same thing and have them treat the world to a pizza bun while they're at it.

I dont even think the little plastic pizza savers are common anymore. Even dominoes doesn't use them, they just switched to a stronger cardboard.

As a person who would love to donate blood and is a universal donor but cannot and who has been in the unfortunate situation of having a love one (my mom) who wouldn’t be here and is somehow still alive because of donor blood and even had my own personal need that saved my life due to septic shock I thank ever person who donates and ask that everyone who can look up and see if your local bank needs blood and if you are a needed blood type and eligible donate because it can be life or death. It might not seem significant but it truly is to so many people. My mother was so badly injured in a head on collision that she shouldn’t have survived and we were told she wouldn’t even after being transferred to a hospital that changed mid flight to a hospital 5 minutes closer because of her blood loss and while her hours long surgery upon arrival where they stopped counting after 50-100 units of blood(not officially on paperwork but in real time) with out she wouldn’t be here.

[@graphosxp]

I'm curious to know which scientists back then didn't believe in *some* kind of eugenics or racial ideology? "we all are bad. Every one of us therefore will find in his own breast the vice which he blames in another. Why do you remark how pale this man, or how lean that man is? there is a general pestilence. Let us therefore be more gentle one to another: we are bad men, living among bad men: there is only one thing which can afford us peace, and that is to agree to forgive one another. "This man has already injured me," say you, "and I have not yet injured him." No, but you have probably injured someone else, and you will injure him some day. Do not form your judgment by one hour, or one day: consider the whole tendency of your mind: even though you have done no evil, yet you are capable of doing it."

It's a french term. It does indeed mean a wardrobe or a closet, it would literally be translated as "keep dress".

lol Having to reach pretty hard when were saying that an unnecessary piece of plastic, that lasted maybe 20 years as a consumerism fad and was objectively a worse alternative to the older method of just putting a ball of dough in the middle, or the current system of just using stronger cardboard somehow 'changed the world.' But hey I guess to be fair those things aren't exactly biodegradable so I guess technically they changed the world's landfills and oceans.

According to tall tales from my friend who has served on a US Navy Ticonderoga-class AEGIS cruiser, the AN/SPY-1B radar will "cook" birds that fly too close (probably only to medium-rare, though) -- it's a 6 megawatt tightly-focused beam, your countertop microwave is maybe 1kW and contained in the box..The vast majority of the time the ship radar is either set to scan or to not follow slow-moving things like birds, but if you took off the filters to look for/disrupt slow-flying quadcopters ... plausible? You definitely wouldn't want to be up on the mast with the radar on. And you can use fighter-jet radars to pop popcorn (as the engineer who invented the microwave oven did in his first intentional cooking experiment). OFC, you don't want to be anywhere within 90 degrees of the nose of the aircraft when doing so.

[@kenbrown2808]

according to tall tales from a gentleman I knew, the watchstanders on the boat he worked on when he was young, found there was a certain point on the bridge wings, where they stayed warmer than on the rest of the exterior superstructure. also, according to him, there was a higher than average incidence of cancer as they aged - his surmise was that they were unknowingly microwaving themselves in stray emissions from the radar system.

I am gobsmacked that the pizza thing was only introduced in the 1980s. I would swear that thing existed before that.

My great aunt had an Amana Radar Range - not an original, but still bigger than her tv with the ability to roast stuff as well and a metal temperature probe. Still scares me lol. I remember in the 70s there was a huge marketing push for the microwave to replace the oven as the main cooker in the home, and you had to buy a bottle of Kitchen Bouquet to paint meat with so it wouldn't look grey.

Want to reheat pizza in the microwave AND get crisper crust? Put a glass of water in the microwave along with the pizza. The glass of water helps take care of the excess moisture in the pizza and therefore, you get a crisper pizza without having to wait for the oven to preheat and so on.

[@patriciagerresheim2500]

Thank you for pronouncing 'Guglielmo' properly. You don't know how often I've heard it butchered. Roebling seems to have taken inspiration from the spinning of yarn. It is first spun clockwise, then several 'singles' are spun together counterclockwise, to relax the tension that would cause it to corkscrew in on itself, making it difficult, if not impossible, to use. If you need thicker yarn, you ply it again clockwise, then counterclockwise, until you get the thickness you want.

Does anyone else remember that there was a step between the two-point and the modern three-point seat belt? At least in some cars there was. You still buckled the lap belt like usual, but an entirely separate shoulder belt was automatic. Here's a quick video kzbin.info/www/bejne/i17JZYOrhLt6pdU My quick research indicates that at the time having those shoulder belts got car manufacturers out of having to have air bags. The problem was that people wouldn't bother to fasten the lap belt, and wearing a shoulder belt with no lap belt was more dangerous than no belt at all, so the law was changed again (probably to the one requiring air bags).

[@kenbrown2808]

what wasn't between the lap belt and the three point belt. that was between the standalone seat belt and the airbag plus seat belt. and those were invented just before the airbag became a thing. they died back out because the airbag was cheaper to make reliable, and more effective. - but what many people don't know, is that the original idea behind the airbag was that it might compensate for people being macho idiots and not using seat belts.

[@geoffroi-le-Hook]

and before that, the seatbelt and shoulder strap were fastened separately. The shoulder strap could be stored above the windows when not in use.

[@gmsherry1953]

@@geoffroi-le-Hook I had forgotten that. A shoulder harness that didn't automatically retract seems like it could be dangerously in the way. It was one thing to shove an unused lap belt behind your rear end, but a shoulder harness that fell down into your peripheral vision at the wrong time ... I'm glad I don't remember that!

Outside toilets were still just about around when I was a kid in the late 60s-early '70s. Gran's next-door neighbour still had one she'd make us use if we went to play with her granddaughter lol. In Wales we call them "y ty bach (twt)" - (required accent not available on my keyboard. Pronounced "uh tea bach - like the composer but the a is a bit shorter, at least in my accent - tut/toot [as in book, not loot]"). Essentially "the (very) little house"; word-for-word, "the house small tiny". Again, the precise translation depends on your locality. I've heard variations on the words meaning small. I've heard some older people use it as a tongue-in-cheek euphemism to the toilet in general, but not that many these days, sadly. My late dad sometimes used it for our downstairs loo; it was indoors, in what we call a "lean to". That's a single storey addition to the side of the house containing 2-3 small rooms, often used for storage and/or a coal shed. Houses built post-war, starting in the '50s, as ours was: red brick, 2½ bedrooms. I grew up in one and now live on the other side of the UK in another; the same size overall, same bedrooms - it's two doubles and a "box room", big enough for bunk beds! - just a different layout. Oh, and two gardens, a smaller front one and large back one. They seem to have been integral to the design nationally. I'm rather attached to it as it reminds me of my childhood. As does the thought of the ty bach!
