  1. Steven Weinberg • Electromagnetic Force: • Over 10 million times stronger than the weak force • Acts over great distances • Weak Force: • Acts over distances smaller than the nucleus • Electroweak Theory: • Weak and electromagnetic forces are just two parts of the same force • Four massless carrier particles mediated the interaction • Two were charged (W particles) and two were neutral (Z particles) • Range of the weak force indicates massive particles though • The theory was later found to be renormalizable, which removed these inconsistencies • Where Is This Theory From? • Came from trying to find a self-consistent gauge theory for the weak force • Steven Weinberg and Abdus • Salam independently • discovered they could do • this if the electromagnetic • force was included 1967: Steven Weinberg and Abdus Salam Independently Propose a Unified Theory Linking the Weak and Electromagnetic Interactions Abdus Salam Sources: http://www.britannica.com/EBchecked/topic/184077/electroweak-theory
