    to think of that, this is one of the cases when basic math knowledge is important/useful outside engineering, finance, or anything that is stereotypically use math.

    The next one will be in the Arctic.

    Also didn’t know we were calling this the UWU shooting.

      I was about to ask whether you can have three colinear points on a sphere, but then I remembered that the Earth is flat.

      Which brings me to another question. What does a circle on a Mercator projection looks like on a sphere?

        It’s still a circle but all the corners add up to 365°, and their where we get the days from.

        You can test this at home. Draw a circle on a paper, wrap it around a ball.

        If you want the edge cases, draw the circle on a sheet of rubber (or maybe a plastic bag?) and stretch it over a ball.

    Even as satire, the worst part is seeing Kirk being treated like he’s anywhere near as important as the Kennedy and Lincoln assassinations.

      If he did, he wouldn’t be able to use circumcircle theorem.

      What’s crazy is that this does fool people despite them drawing circles many times around triangles in their math class.

      Wasn’t that in elementary or middle school?

    Guys, I went to the center of the circle, and there was a completely normal looking tree there. Maybe too normal. What could it mean?

    I wonder what size the circle would be if you took in to account the earth’s curvature.

    Are there any map projections that allow for accurate projection of circles across arbitrary points?

        I think it should still be possible to define a perfect circle from 3 points on a globe, tho

        Imagine the 3 points on the globe defining a plane, and then just intersecting the globe by that plane, you’d have a perfect circle on a sphere that still goes through the original 3 points if I’m visualizing this in my head correctly, might try this in blender or something

      If you drew in on a globe, it would look deformed in this projection. I think the radius wouldn’t change, but it would look “wider” towards the north

          Looking at the stereographic projection, there is a longer distance between points the father you get from the center of the map. Although the latitude lines remain circular in a polar projection, the map scales to avoid distortion father from the constant growth of the map once you leave the projected hemisphere. The northern hemisphere in an artic projection still must distort, making geometry a mess.

          Goode homolosine projection is closer to keeping that distortion down, but all maps are an estimate due to the way a 3d curve is translated to a flat surface.

          All that said, and I know I’m being pedantic, you could come really close by calculating the center of the circle in a sphere, then projecting the map stereographically from the center. That specific projection would come the closest, given the irregular shape of the Earth.
