How /math/ is /sci/?

time for your brainteaser. I have to admit though, I dont actually know the solution myself. its not homework though, I promise.

lmao what the fuck are you trying to say

Its not possible to map from a flat surface to a curved one like that, no matter how many surfaces it has.
What you CAN do however is map two points, that determine a line as the shortest distance between them, from a flat surface onto a curved one, and then find the new shortest distance on the curved surface, which is called the geodesic defined as [math]0 = \frac{d(dx^\alpha d\lambda)} {d\lambda} + \Gamma^\alpha_{\mu\lambda} \frac{dx^\mu} {d\lambda} \frac{dx^\lambda} {d\lambda}[/math] where [math]\Gamma^\alpha_{\mu\lambda}[/math] denotes the Cristoffel Symbol determined by the metric of the curved space.

are you saying you couldnt tie yarn through a klein bottle? imagine you had a hanky a pen and a klein bottle. at least some subset of solutions are physically verifiable, no?

so how is this not a knot? if you join both ends then it is stuck to the bottle...

wow thats awesome. i never saw that before. this website is so functional but so inacessable to newfags.
