The third of Hilbert's list of mathematical problems, presented in 1900, was the first to be solved. The problem is related to the following question: given any two polyhedra of equal volume, is it always possible to cut the first into finitely many polyhedral pieces which can be reassembled to yield the second? … See more The formula for the volume of a pyramid, $${\displaystyle {\frac {{\text{base area}}\times {\text{height}}}{3}},}$$ had been known to Euclid, but all proofs of it involve some form of limiting process or calculus, … See more Dehn's proof is an instance in which abstract algebra is used to prove an impossibility result in geometry. Other examples are See more Hilbert's original question was more complicated: given any two tetrahedra T1 and T2 with equal base area and equal height (and therefore equal volume), is it always possible to find a finite number of tetrahedra, so that when these tetrahedra are glued in some … See more • Proof of Dehn's Theorem at Everything2 • Weisstein, Eric W.

WebJan 30, 2024 · This was the first of Hilbert's problems to be solved and the solution belongs to his student, Max Dehn, who introduced a numeric ``invariant" in a rather ingenious way. In this talk we will not only discuss Hilbert's third problem and Dehn's solution, but also take time to review some of the rich history behind Hilbert's question which dates ...

An attempt at such a proof had already been made by R. Bricard in 1896 but Hilbert's publicity of the problem gave rise to the first correct proof—that by M. Dehn appeared within a few months. The third problem was thus the first of Hilbert's problems to be solved. gregg olsen a wicked snow
