A Strange Map Projection (Euler Spiral) - Numberphile

The Euler Spiral map both horrifies and intrigues me.

Oh no, wait until the flat orangers see this video...

"In 3 hundred meters, make a loop around the earth, and then turn right"

Normal people: the earth is round Flat earthers: the earth is flat Mathematicians: the earth should be a spiral

This is spiralling out of control.

I love Hannah's presenting "style", relaxed but enthusiastic at the same time. I've always been a bit of nerd when it comes to peeling oranges. One of my favourites is to make a little lantern out of it. I also remember seeing (in my grandpa's magic book) a way of peeling an orange that allows you to remove the orange but the peel stays as a sphere that can expand to get the orange out but keeps the overall shape. I've forgotten how to do it though. I'll need to see if I can find out how to do it again. I doubt it would work as a map though, but it looks cool.

I don't know if what I enjoyed more - Hannah's narration or the mathematics. Both are delightful

"I think we should prioritize mathematical beauty over geographical practicality." - Hannah Fry I can't tell you how much I love this statement.

I've learned about gaussian curvature when the Klein Bottle professor explained to me how to correctly hold a pizza slice!

My favorite map of the globe was designed by Buckminster Fuller. It projects the earth's surface onto an icosahedron, distributing the distortions across 20 triangles. It also radiates the continents out from the north pole, displaying the world as basically one large land-mass surrounded by one continuous ocean. As much as possible, the cuts are in the ocean.

Hannah Fry: “We’ve only got this room for an hour. What should we do?” Obviously cut up a globe into an Euler spiral

Hello, I am from the Flat Orange Society. Mind if we have a word?...

New Hannah Fry video?!?!? It's like christmas to me

"Mathematically beautiful, if Geographically impractical" 😂

4:05 “There are a few different options here, but none of them are going to get you completely around this problem.” I see what you did there.

As a geographer, I really loved this video and learning about this new projection. This projection shares a feature with the Mercator projection. On the Mercator projection there is one place where there is zero distortion, which is the equator, where the cylinder would touch the sphere. The Euler spiral enables you to create a similar line of zero distortion that encompasses the whole globe. Of course, in both cases the true line of zero distortion is a one dimensional line, which is why you have to go to infinity in the spiral to get there, but I completely see the beauty in this. I love it.

Imagine folding the Euler Spiral map in the car.

If hannah fry was my maths lecturer, I wouldn't miss a class
