Gabor Domokos is a Hungarian mathematician and engineer. He is best known for his 2006 discovery of gomboc, a class of three-dimensional (3D) convex bodies that have one stable and one unstable point of balance. Their shape helped to relate the body structure of some tortoises and their ability to recover after being placed upside down. Domokos is mostly known for his work on mono-monostatic bodies, that is, convex bodies that have one stable and one unstable point of balance. In 1995 he met the prominent Russian mathematician Vladimir Arnold who suggested that 3D mono-monostatic bodies do exist and urged Domokos to find one.Aided by his wife, Domokos developed a classification system for 3D objects based on their points of equilibrium by analyzing pebbles and noting their equilibrium points. In one experiment, the couple tried 2000 pebbles collected at the beaches of the Greek island of Rhodes and found no single mono-monostatic body among them, illustrating the difficulty of the problem. In 2006 Domokos and his student Péter Várkonyi theoretically found a stable class of mono-monostatic solutions, which they named gömböc
