Mass-to-charge ratio used as its unit in the field of mass spectrometry. Some fields use the charge-to-mass ratio ("Q"/"m") instead, which is the multiplicative inverse of the mass-to-charge ratio. The 2014 CODATA recommended value for an electron is = . When charged particles move in electric and magnetic fields the following two laws apply: where F is the force applied to the ion, "m" is the mass of the particle, a is the acceleration, "Q" is the electric charge, E is the electric field, and v × B is the cross product of the ion's velocity and the magnetic flux density.

How to Photograph an Atomic Bomb A traveling exhibit based on the book was purchased by the Atomic Testing Museum and put on display in 2007. In 2010, "The New York Times" featured a 23-image slideshow on its website with photos taken from the book accompanied by an audio recording of George Yoshitake, then one of the few surviving cameramen. How to Photograph an Atomic Bomb How to Photograph an Atomic Bomb is a book written by Peter Kuran and published in 2006 by VCE. It documents the stories of the men who photographed US nuclear weapons tests between 1945–1963 and the techniques they used to
