Aston began researching the different atomic weights of two forms of neon at Cambridge in 1913 under the guidance of J.J. Thomson (discoverer of the electron). He left to fight in the First World War, but later continued, replacing Thomson's parabola apparatus with the mass spectrograph he had himself invented. His spectrograph gave more concentrated effects, which created greater clarity of identification. Aston received the Nobel prize for chemistry in 1922. "His achievements were kept continually before the scientific public by revised editions of his excellent book Isotopes (1922). This included observations on the abundance and distribution of isotopes and a clear forecast of the power and dangers of harnessed atomic energy."
