Typically based on a particular money market rate or the average interest rate in a particular trading market, different index rates are used for each type of loan. In the United States, for example, the prime rate is the most common factor used to determine interest rates for variable rate loans.
Edward Teller (1908-2003) was a Hungarian-born American theoretical physicist. Teller, along with Leo Szilard and Eugene Wigner, helped urge President Roosevelt to develop an atomic bomb program in the United States. Teller joined the Los Alamos Laboratory in 1943 as group leader in the Theoretical Physics Division.
Edward was the name of several Saxon and eight English kings, and is the name of the youngest son of the current queen. It was an early arrival in the New World -- there were several Edwards in the Jamestown colony and six on the Mayflower. Youngish actors Edwards Norton, Burns and Furlong help keep the name's image fresh. Parents today are more likely to prefer nicknames Ted or Ned to the traditional Ed or Eddie-- or, just as likely, to use the name in full.
