Description
This is a lectures for general audience. Consider a part of a surface (a sphere for example). How to draw a planar map of this surface such that all the angles between curves on this surface would be preserved and the variation of the scale across the map would be minimal? I explain how this is related to conformal maps and explain a proof of Chebyshev’s theorem about such a map in the case of a sphere.
