Introduction to electromagnetism is a quantity used to determine how a particle will behave in an electric field. There are three possible "types" of charge: positive, negative, and neutral. However, the distinction between positive and negative is by convention only. Electric charge is quantized in units of the elementary charge, formula_1, where a proton has a charge of formula_2 and an electron has a charge of formula_3. The SI unit of charge is the coulomb. The elementary charge formula_1 was first measured by Robert Millikan in his oil drop experiment in which the electric force on the particle is set to exactly counter
How to Dismantle an Atomic Bomb How to Dismantle an Atomic Bomb How to Dismantle an Atomic Bomb is the 11th studio album by Irish rock band U2. It was released on 22 November 2004 on Island Records and Interscope Records.
