Measurement of Time

Science > Physics > Units and Measurements > Measurement of Time In this article, we shall study techniques of measurement of time. Time is the interval between two events. The study and science of time measurement is called chronometry or horology. Chronology, as opposed to chronometry, is the science of arranging events in their order or sequence […]
