Solar zenith angle minutes of arc, which is less than the apparent angular radius of the sun. The formula also neglects the effect of atmospheric refraction. Sunset and sunrise occur (approximately) when the zenith angle is 90°, where the hour angle "h" satisfies Precise times of sunset and sunrise occur when the upper limb of the Sun appears, as refracted by the atmosphere, to be on the horizon. A weighted daily average zenith angle, used in computing the local albedo of the Earth, is given by where "Q" is the instantaneous insolation. For example, the solar elevation angle is : An exact calculation
While(1 Is Less Than 2) 3.5/5 stars. Rolling Stone, however, was more critical of the album stating "Deadmau5 has turned from an electro-house polymath into the world's most unnecessary Nine Inch Nails tribute act" giving it 2 stars out of 5. Slant Magazine was equally critical saying "Deadmau5 enters the fray with the advantage of deeply diminished expectations. His latest, While(1<2), comfortably clears the bar set by his contemporaries, and that would be impressive if the bar wasn't buried underground" also awarding it 2 stars. Note While(1 Is Less Than 2) While(1<2) (stylized as while(1<2); pronounced "while one is less than two") is the seventh
