Tirohia te whiti i raro nei, me te ka whakahoki i te pātai i muri i roto i te reo ano rite te whiti: Passage: puta geometry rerekētanga i roto i ona ake ka whakamahia Einstein te reira i roto i te pānga whānui. wāhi tino hou o te pāngarau pērā i arorau pāngarau, topology, me John von Neumann o ariā kēmu huri i te momo o ngā pātai e taea te whakahoki e tikanga pāngarau. i whakaahuatia momo katoa o ngā hanganga te whakamahi i axioms, me te hoatu ingoa rite mokowā ine, mokowā topological etc. Ka rite ki te pāngarau mahi, i whakaahuatia te ariā o te hanganga whakaahuatanga ano, a arahina ki te kāwai ariā. Grothendieck ko Serre recast geometry taurangi te whakamahi i te ariā puranga. i hanga nui i roto i te ako kounga o ngā pūnaha hihiri e kua tīmata Poincaré i roto i te 1890s. pātai: He aha te ahua o te ariā i whakawhanakehia Neumann?
