Phase angle (astronomy) less than 90° represent backscattering; values greater than 90° represent forward scattering. For some objects, such as the Moon (see lunar phases), Venus and Mercury the phase angle (as seen from the Earth) covers the full 0–180° range. The superior planets cover shorter ranges. For example, for Mars the maximum phase angle is about 45°. The brightness of an object is a function of the phase angle, which is generally smooth, except for the so-called opposition spike near 0°, which does not affect gas giants or bodies with pronounced atmospheres, and when the object becomes fainter as the angle approaches
While(1 Is Less Than 2) While(1 Is Less Than 2) While(1<2) (stylized as while(1<2); pronounced "while one is less than two") is the seventh studio album by Canadian electronic music producer Deadmau5, released on June 17, 2014 by Mau5trap, Virgin EMI and Astralwerks, his only album to be released by the latter. The album is a departure from the bass-heavy, upbeat template of his previous work, instead foraying in a more experimental direction, with tones of downtempo and ambient music. Many of the songs on the album were originally uploaded to Deadmau5's SoundCloud account before they were removed from the site in early 2014. The
