Master of The math of slicing pizza
artiteacher The Pizza Theorem
Cut it off-center, take every other slice, equal shares of pie!
artiteacher The 'U-fold' is the most efficient way to eat large, thin-crust pizza slices.
artiteacher Flat surfaces have zero Gaussian curvature, which must be preserved when bent.
Gauss's theorem: Carl Friedrich Gauss's 1827 theorem on curvature is the exact reason mapmakers cannot make a flat map without stretching the Earth.
The degree to which a geometric surface deviates from being completely flat. Carl Friedrich Gauss's 1827 theorem on this concept explains why folding a pizza slice keeps it rigid.
In what year did Gauss publish his groundbreaking work on the curvature of surfaces?
Which 19th-century mathematician's theorem explains why folding a pizza slice keeps it stiff?
What happens to the Gaussian curvature of a surface when you bend it without stretching or tearing?
