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
The Fox (What Does the Fox Say?) did not know about its existence when producing "The Fox". Like many viral music videos, "The Fox" has become an Internet meme and has been extensively covered and adapted by others, with some of the most prominent being a cover by The Ohio University Marching 110 who had previously covered "Gangnam Style" and LMFAO's "Party Rock Anthem"; a cover by Tay Zonday of "Chocolate Rain"; an acoustic guitar cover of the first verse by Tyler Ward; an adaptation based on the popular video game "League of Legends" entitled "What Does Teemo Say?"; and an adaptation by Annoying Orange entitled "The
