Ah, this reminds the time when cluster munitions were bright yellow, so you could spot them and stay away.
And food aid packages were bright yellow, so you could spot them and easily collect them.
Yeah…

And asbestos. I work in hazardous materials and the amount of things that had asbestos in them is terrifying.
Asbestos carpets, and asbestos-structured paint for fucks sake. Imagine how many peoppe sanded down asbestos paint…
The good life of the 80s?
well, OP seems to be a healthy white straight male in his 20s, otherwise they definitely wouldn’t comment this.
Sorry, I left my magic wand in my other pants…
Me too, but I’m not really at “donating Javelin” levels of wealth.
It’s immensely noticeable on radar. That giant round engine is going to stick out like a sore thumb on radar and IR.
No, you see, this is just how amazing Russian AA missiles are!
Most people don’t want to break the sacred bond of pretending you’re busy, because then next time, they might get caught for doing the same.
Russia is huge, but it’s basically empty too.
And there isn’t any same-day delivery to the front from a Depot in Kamchatka, so the size isn’t very useful when it comes to offensive logistics
One of the famous ones is laminar flow in a tube or pipe. There’s a very nice physics formula to compute Reynolds number, and when it’s over 3500, flow is usually turbulent, and below 2000 it’s usually laminar. And anywhere in between? Eh, it kinda depends. Unless there are bends in the tube, then it depends even more. Oh, and when your flow is not in a tube, the values wildly vary even more.
There’s a concept of “angle of repose”, basically at what slope will loosely poured materials sit. There are super complex modern models to compute that, based on grain size and shape. But there’s also a half-page table listing anything from asphalt to coffee beans, which is literally the law in a lot of countries. That table is older than the age of sail in most cases and zero maths went into it.
And then there is the hilarious official ways to determine the characteristics of concrete and asphalt. The flow test, for example includes the highly scientific steps of “pour into a specific cone and poke 25 times with a two by four, then measure the circle on the floor”. This number is then used in several calculations.
Calculus is a specific field of mathematics, mostly to do with limits, integrals and derivatives. Those all feature very heavily in working out loads and stresses.
But it’s unfair to say the Roman didn’t have calculus. It wasn’t formal calculus, but they absolutely had mathematics, and the Greeks worked out the exhaustion method a century before the Via Appia was even started.
You don’t need calculus to do some very impressive building, you can go very very far with experience, rules of thumb and basic maths. Hell, ask any civil engineer and they’ll gladly show you some common formula that makes physicists cry.
Ok, technically correct, in that drones are aircraft. But it’s not the greatest description, and their main use is anti-drone, with a little anti-helicopter thrown in.
The ZSU-2 om which this is based was anti-aircraft when it was developed, in 1949, but that’s not a thing anymore today. Works great on drones though!
Anti-drone? You’re not going to hit any jets with that, unless you’re supremely, insanely lucky.
I love that “the right” is someone wearing a mask.
Most dangerous thing anywhere is cars, tbh.
I love that there’s a wikipedia page on this.
I hate that doing the wrong thing consistently automatically makes it the right thing.
Seras Victoria is from Hellsing, and that’s a 30mm anti tank rifle, a weapon that (as far as I know) doesn’t exist. Even the bigger antitank rifles only went to 20mm.
I hate when people assume I’m the office assistant or new hire when I’m the Assistant Director.
I started my own company, with my name on it. I want to punch old white man who asks if “Mr Alcaran” is in, or if the owner is my father or husband.
I once did an interview with someone who asked me if this was my internship. He didn’t get the job.
Yeah, this definitely looks like airdropped chocolate to me bro.
