Anemometer beam exits reflect, or backscatter, the light back into a detector, where it is measured relative to the original laser beam. When the particles are in great motion, they produce a Doppler shift for measuring wind speed in the laser light, which is used to calculate the speed of the particles, and therefore the air around the anemometer. Ultrasonic anemometers, first developed in the 1950s, use ultrasonic sound waves to measure wind velocity. They measure wind speed based on the time of flight of sonic pulses between pairs of transducers. Measurements from pairs of transducers can be combined to yield
What Does Anything Mean? Basically lyrics of the Beatles song "She Said, She Said". "What Does Anything Mean? Basically" was released 1 October 1985 on record label Statik. "What Does Anything Mean? Basically" has been generally well received by critics.
