Detail: He lived 1900 to 1979 and invented holograms and Gabor filter [1946]. Instruments cannot measure both frequency and time precisely and simultaneously. Impulses happen at precise times, but impulses have wide component-frequency range. For one frequency, wave cycle happens over wave period. The tradeoff defines the minimum information quantity {quantum, information}.
