Bohr: the classic principle of least action states that particle from A to B the total action (energy x time) is smallest or largest of all trajectory. This is adapted to say the action of the electron going through its orbit in a complete cycle (m*v*2πr) must be integer multiple of h. This explains the atomic radiation spectra. 3. crime novelist paretsky
