Visualising the Poincaré Conjecture Proof

Science used the above diagram about a year ago to illustrate how mathematician Grigori Perelman had come to prove the infamous Poincaré Conjecture. Perelman used “Ricci flow,” or “a procedure for transforming irregular spaces into uniform ones,” in order to prove that something or other will always be a hypersphere… In the above image we [...]

Rubiks Cube – Solve in 26 moves

Some smart thinking by Gene Cooperman and Daniel Kunkle and 63 hours of computation with a super computer has led to the proof that every Rubiks cube can be solved in 26 moves or less. Read more …
