In 1968 (10 November), Lovelace discovered period \(P\approx 33\) ms of the Crab Pulsar.[1][2] As a graduate student working at Arecibo Observatory, Lovelace developed a version of the Fast Fourier transform program [3] which was adapted to run on the Arecibo Observatory's CDC 3200 computer [4]. This program helped to separate the periodic pulsar signal from the noise, and one night he discovered the period of the Crab pulsar, which is approximately 33 ms (33.09 ms).[1]<new ref=”Lang2013”>"Astrophysical Formulae Space, Time, Matter and Cosmology" Kenneth R.
