Blue

Blue is the colour between violet and green on the optical spectrum of visible light. Human eyes perceive blue when observing light with a wavelength between 450 and 495 nanometres. Blues with a higher frequency and thus a shorter wavelength gradually look more violet, while those with a lower frequency and a longer wavelength gradually appear more green. Pure blue, in the middle, has a wavelength of 470 nanometres. In painting and traditional colour theory, blue is one of the three primary colours of pigments, along with red and yellow, which can be mixed to form a wide gamut of colours. Red and blue mixed together form violet, blue and yellow together form green. Blue is also a primary colour in the RGB colour model, used to create all the colours on the screen of a television or computer monitor.

The modern English word blue comes from Middle English bleu or blewe, from the Old French bleu, a word of Germanic origin, related to the Old High German word blao. The clear sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. When sunlight passes through the atmosphere, the blue wavelengths are scattered more widely by the oxygen and nitrogen molecules, and more blue comes to our eyes. Rayleigh scattering also explains blue eyes; there is no blue pigment in blue eyes. Distant objects appear more blue because of another optical effect called atmospheric perspective.

Track listing

Personnel

Essence (Lucinda Williams album)

Essence is Lucinda Williams' sixth album. It was released in 2001. The album debuted on the Billboard 200 at number 28, selling about 44,500 copies in its first week. According to Billboard as of February 2008, the album had sold 336,000 copies in the U.S.

Reception

Essence was highly anticipated coming after a three-year gap from her lauded Car Wheels on a Gravel Road and the critical reviews reflect that. Although positive, none rate the album as highly as her breakthrough. Robert Christgau, who raved about Car Wheels, called the album "imperfect" but still praised her artistry saying "[she] is too damn good to deny." Reviewers noted the difference in tone between the two albums with Rolling Stone citing the "willful intimacy" of the music while Spin contrasted its "halting, spare" presentation with Car Wheels "giddy, verbose" one. In a review posted by Salon the album was called "an emotional mess of a masterpiece".

Q listed Essence as one of the best 50 albums of 2001.

Science Fantasy (magazine)

Science Fantasy, which also appeared under the titles Impulse and SF Impulse, was a British fantasy and science fiction magazine, launched in 1950 by Nova Publications as a companion to Nova's New Worlds. Walter Gillings was editor for the first two issues, and was then replaced by John Carnell, the editor of New Worlds, as a cost-saving measure. Carnell edited both magazines until Nova went out of business in early 1964. The titles were acquired by Roberts & Vinter, who hired Kyril Bonfiglioli to edit Science Fantasy; Bonfiglioli changed the title to Impulse in early 1966, but the new title led to confusion with the distributors and sales fell, though the magazine remained profitable. The title was changed again to SF Impulse for the last few issues. Science Fantasy ceased publication the following year, when Roberts & Vinter came under financial pressure after their printer went bankrupt.
