About the microsecond
The microsecond became measurable with the development of oscilloscopes and high-speed electronics in the mid-20th century.
In everyday use the microsecond appears in CPU operations, high-frequency trading, radar pulse timing, and laser physics. As a point of reference: light travels about 300 meters in one microsecond.
