Albedo formula_5 (also called blue-sky albedo) can then be given as: Directional-hemispherical reflectance is sometimes referred to as black-sky albedo and bi-hemispherical reflectance as white-sky albedo. These terms are important because they allow the albedo to be calculated for any given illumination conditions from a knowledge of the intrinsic properties of the surface. The albedos of planets, satellites and minor planets such as asteroids can be used to infer much about their properties. The study of albedos, their dependence on wavelength, lighting angle ("phase angle"), and variation in time comprises a major part of the astronomical field of photometry. For small
So Beautiful or So What Simon. At the end of 2011, "So Beautiful or So What" appeared on several top-ten lists curated by music publications. "Rolling Stone" named it the year's 3rd best record, while "Mojo" ranked it 15th. It was voted the 14th best album of the year in "The Village Voice"s Pazz & Jop, an annual poll of American critics nationwide. Christgau, the poll's creator, ranked it 3rd on his year-end list for "The Barnes & Noble Review". Years later, he said "So Beautiful or So What" and Simon's 2016 album "Stranger to Stranger" had remained the singer's "21st century prizes". All songs
