I love this chart. Because pasteurization is a result of capitalism, not food safety. The EU doesn’t pasteurize their eggs because their chickens are vaccinated against salmonella. The USA does not vaccinate their chickens because it would hurt Big Agriculture and all their egg pasteurizing factories.
We have to pasteurize milk because of the awful conditions of factory farming - where disease is rampant. Again, this is a result of capitalism. And again, you can see drastic difference in the products in the EU vs the USA. Some EU cheeses are required, by law, to use raw milk. It’s safe there.
My biggest issue with this is the flight part - it’s a counterintuitive explanation that doesn’t really explain how to make the flight work. It’s not technically wrong, and if you trace that cross-section you will get a working aerofoil. However, you can’t make the Wright Flyer on that explanation, or in fact any of the early aeroplanes that were constructed with simple fabric stretched between wooden frames.
A far more useful and intuitive explanation is that planes fly by flow-turning, basically the interaction between the aerofoil and the air turns the air in one direction, which pushes the aerofoil in the other. This also means the air below will end up slower than the air on top, which will create a pressure differential. Either of these methods can completely describe how flight works.
Also, a plane isn’t just two aerofoils attached to a central body. Early planes were at least biplanes, and you need horizontal and vertical stabilisers to have full control. You need flaps that give you pitch, yaw and roll, and you need the centre-of-mass - the point where it balances - to be in front of the centre of pressure. That means you need the stabilisers to be at the back to keep the plane stable like a dart.
This isn’t just a “well akshually”, although it sort of is. If you tried to follow the advice as-written and didn’t know this, there’s a good chance you’d end up on the long list of people killed by their own inventions. Actually, I suspect most of these explanations give you just enough information to kill yourself but not really enough to actually make any of them work from first principles.
Pretty much everyone in this thread needs to go read Ryan North’s book “How to Invent Everything: A Survival Guide for the Stranded Time Traveler”.

Or, if you don’t have time, just print this out and keep it with you at all times:
“Wrap some copper wire around a core”
Mr. Stegosaurus, please point out the nearest refinery so I can grab some copper wire.
I don’t know if this helps. It’s enough to know you’re fucked.
I find this to be brilliant.

I’ve been meaning to buy this! Does he have a section on how to handle no one speaking your language?
