@gavwould: Gabriel's Horn defies logic You can fill Gabriel's Horn with exactly one bucket of paint... but you could never paint the outside. Here is one of the most mind-bending paradoxes in mathematics and geometry, explained in 60 seconds. Even though the shape stretches infinitely, its volume is finite (exactly Pi!), while its surface area grows forever. #math #mathparadox #stem #infinity #geometry
just put it in. a bigger gabriel horn thats filled with paint

Math be like, "Bro this thing I thought of is IMPOSSIBLE." Then describe an impossible thing and expect you to be impressed. Imagine if an architect came up with an idea to make a building out of cotton candy that curved in on itself and expected you to think that's intelligent.

Anyone that’s painted anything knows it always takes slightly more than 1 bucket so you gotta buy 2

Well actually the horn becomes unpaintable as the diameter approaches the size of an atom the horn would cease to exist as a tangible object past that point

Because in my opinion it’s wrong it’s like saying .99999… = 1, that infinite section is still there so it doesn’t at up to a finite amount is what I think is right

How can circles be filled up but circle diameters can't be? 🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔

here's an example to help you understand:
Imagine you have a cake. Slice it in half and stack the two halves on top of eachother. Then slice the top half and stack that quarter on top of the other quarter. You can theoretically keep doing this forever, but the volume of cake you used in the beginning is still the same. The surface area, however, can expand infinitely

Good. Another concept that I am too stupid to understand. Others include: why mobius strips work the way they do, imaginary numbers, the expansion of the universe, and magenta.

Well theoretically yeah but if we account for atoms being a thing than yeah not really

Christal0611 :
If this is the ideal mathematical horn, then the paint must also be treated as an ideal continuous substance with no molecules or minimum thickness. But once you argue that real paint eventually cannot pass through because its molecules have finite size, you have switched to physics. In that physical model, the horn also cannot remain infinitely long, infinitely thin, and perfectly continuous. You cannot apply molecular limits to the paint while leaving the horn mathematically ideal. A physically truncated horn has finite surface area and can be painted with a finite amount.
