Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Giravhiti neelectromagnetism nguva dzose zvaigona kuvapo pamwe chete nenzira ine rugare sezvinopinda murondedzero yamasimba ekare, asi kwamakore akawanda kwakaratidzika kuti giravhiti yaisagona kunyange kubatanidzwa mugadziriro yequantum, tisingatauri pamusoro pokubatanidzwa namamwe masimba makuru. Nokuda kwechikonzero ichi, basa rokubatanidza, kwechikamu chikuru chezana ramakore rechimakumi maviri, rakanangidzirwa pakunzwisisa masimba matatu e"quantum": electromagnetism uye masimba asina simba uye akasimba. Maviri okutanga akabatanidzwa muna 1967-1968 naSheldon Glashow, Steven Weinberg, naAbdus Salam kuva simba re"electroweak".  Mubvunzo: Ndeapi masimba ezvinhu zvakasikwa anobatsira kuti zvinhu zvirambe zvakabatana?
