A silver bullet is a magical solution to a confusing problem. Silver bullets have long had the reputation of being the only ammunition that can kill a werewolf, since the eighteenth century. In 1933, The Lone Ranger, a fictional masked Texas Ranger who roamed the Old West with his faithful friend, Tonto, debuted on American radio. His bullets were made of silver, Silver was his horse’s name, also. Michael Briggs found that silver bullets are actually slower and less accurate than traditional lead bullets.
A magic bullet is a medicine or other remedy that is wonderfully specific and efficacious. It was coined in 1906 by scientist Paul Ehrlich when he used the German word zauberkugel to describe natural antibodies that seem to fly to their specific objectives in a charmed fashion. Zauberkugel was translated into English as magic bullet in 1938 and by 1940, the term was common in American newspapers. As time has passed, the definitions of silver bullet and magic bullet have grown closer in meaning.
