Anemometer turbines usually requires a refresh rate of wind speed measurements of 3 Hz, easily achieved by sonic anemometers. Three-dimensional sonic anemometers are widely used to measure gas emissions and ecosystem fluxes using the eddy covariance method when used with fast-response infrared gas analyzers or laser-based analyzers. Two-dimensional wind sensors are of two types: Acoustic resonance anemometers are a more recent variant of sonic anemometer. The technology was invented by Dr Savvas Kapartis and patented in 2000. Whereas conventional sonic anemometers rely on time of flight measurement, acoustic resonance sensors use resonating acoustic (ultrasonic) waves within a small purpose-built cavity in
What Does the Bee Do? the bomb that Slater set explodes, badly burning one of them. "What Does The Bee Do?" is a children's poem from the late 1800s by Christina Rossetti. Margaret Schroeder's daughter recites it in the episode. "IGN" gave the episode a score of 8.5 out of 10, saying that it "effortlessly hits that sweet spot between advancing the plot while developing characters, much in the same way that the Season 2 premiere did." "The A.V. Club" rated the episode an "A-". The episode was watched by 2.546 million viewers. It fell two tenths, to 1.0 million adults 18-49 rating. What Does
