Mass in special relativity detail by Oliver Heaviside (1889) and George Frederick Charles Searle (1897). So the electrostatic energy behaves as having some sort of electromagnetic mass formula_25, which can increase the normal mechanical mass of the bodies. Then, it was pointed out by Thomson and Searle that this electromagnetic mass also increases with velocity. This was further elaborated by Hendrik Lorentz (1899, 1904) in the framework of Lorentz ether theory. He defined mass as the ratio of force to acceleration, not as the ratio of momentum to velocity, so he needed to distinguish between the mass formula_26 parallel to the direction of motion
Our Velocity game Our Velocity "Our Velocity" is the first single from "Our Earthly Pleasures", the second album from the band, Maxïmo Park. The single was released two weeks prior to the release of the album, on 19 March 2007. The music was written by Duncan Lloyd and the lyrics by Paul Smith of the band. The video of the song features the band being multiplied in a white room while playing the song. It was directed by Nima Nourizadeh.
