The Banach - Tarski Dupla - Shrinker recently made an appearance on an installment of Futurama . Using it , Bender get to make two , slightly small , written matter of himself . The modest Benders are why they added the ‘ shrinker ’ part of the name . The actual Banach - Tarski theorem allows an target to engender a perfect copy of itself , at its precise size , just by being chopped into bits .
The paradox was first describe in 1924 by Stefan Banach and Alfred Tarski . They showed that , if someone were to hack up a unanimous ball of any sizing into six very just - shaped pieces , those pieces could be rearranged and used to spring two new solid balls , each on the nose the same size of it as the original . The pieces would be re - positioned , but not stretched or blown up to declamatory proportions . Later , another mathematician reduced the number of pieces necessary to do this to five . It dumbfound even stranger . Another version of the theory has a ball the size of it of a pea plant being chopped up and redo to form a ball the size of it of the Sunday .
This seems intuitively impossible , but as an summate bonus , it ’s theoretically impossible as well . Physics says that tidy sum can not be created or destroy with nothing more than a pair of scissors . Anyone who manage to attain a practical Banach - Tarski surgery would essentially be duplicate the mass of something , like conjuration .
It ’s not magic that drives this paradox . Rather , it ’s a certain set of assumptions and some tricks with intensity . The theoretical Banach - Tarski ball can be cut into fragments that are infinitely small and thin . These fragments are special material body for a rationality . If we wanted to discover the volume of a regular hexahedron , we could measure one side and square block that measurement . If we encountered a orthogonal strong , we could simply multiply the base area times the summit . But some shape do n’t have such well defined volume . The shapes that the ball would have to be cut into would be so toothed and scalloped that they would be more like a scatter of points than a satisfying . As such , their mass is nebulous enough to double over if they ’re put in the correct berth . At least theoretically .
