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.
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
They are made of steel, lmao… how silly do they think we are.
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.
Has anyone ever sent you nudes cause of your name?
of course the shortest distance is a straight line, that’s literally the definition of a straight line.
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.
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.
