Shortwave radio amateurs (ham radio operators) are used to this curvature. For example, if I‘m in Germany and want to point my directional antenna towards Australia, it would be a bit more eastwards than one would expect from looking at a flat map.
It's honestly amazing how easily one can do rudimentary star navigation, and how involved it can become when you try to get more information out of the view of the sky
It’s a bit like walking over a hill. You can straight-line up and over or you can walk around the side partly up the slope and cover the same distance. Mercator shows great circle as straight lines.
All lines of longitude are big circles and all lines of latitude, without the equator, are small circles. But not vice versa... The shortest line between two points on a globe is always part of a big circle and called an orthodrome.
Great circle? Get a globe and a piece of string. Stretch the string between any two points of interest and its path across the globe is a great circle. As stated elsewhere, the equator is a great circle, and all lines of longitude (which go through both poles) are great circles. But ANY circle that goes around the earth and has its center at the center of the earth is a great circle. Traveling along a great circle is always the shortest distance between two points (on an idealized, perfect sphere, earth). Reality is always a bit more complicated, but not much in this case if the distances are great. Anyway, especially useful when sailing or flying.

As the Earth is mostly covered in uncarbonated water therefore, technically it's flat
I'll get my coat...
Well, despite your best efforts, it's still water.
Can't believe there was no 'waffle' on the comedy rain...Seriously, excellent video once again. Very much appreciated Sir.
super underrated youtuber
I believe the walking club navigator was referring to the ACORN EARTH THEORY.
That would explain the top down circumference deviations.
Cheers!
Sticks and mud will do fine. Chalk and talk with a blackboard is an old fav of mine.
I would LOVE if you would explain various map projections, especially with the help of oranges! 😁
If you keep following any bearing (other than N, E, S, W) you will follow a spiral path towards a pole, called a rhumb line

Wayne, have you hiked Derwent Edge? Saw some pictures of the area, it's beautiful!
Yes I've been there many times.

Perish the thought that you ever become a “real “ you tuba 🎺
👍
Great circle: equatorial or polar.
Lesser circles: higher latitudes, or parapolar

Me understands mud and stick more good😐
Its flat bro trust me not this 🟢more likely to be this 🟩
Let’s keep the comedy to the rain, eh, bro’. 😂
