Soap

In chemistry, soap is a salt of a fatty acid. Consumers mainly use soaps as surfactants for washing, bathing, and cleaning, but they are also used in textile spinning and are important components of lubricants.

Soaps for cleansing are obtained by treating vegetable or animal oils and fats with a strongly alkaline solution. Fats and oils are composed of triglycerides; three molecules of fatty acids attach to a single molecule of glycerol. The alkaline solution, which is often called lye (although the term "lye soap" refers almost exclusively to soaps made with sodium hydroxide), brings about a chemical reaction known as saponification.

In this reaction, the triglyceride fats first hydrolyze into free fatty acids, and then these combine with the alkali to form crude soap: an amalgam of various soap salts, excess fat or alkali, water, and liberated glycerol (glycerin). The glycerin, a useful by-product, can remain in the soap product as a softening agent, or be isolated for other uses.

Soaps are key components of most lubricating greases, which are usually emulsions of calcium soap or lithium soap and mineral oil. These calcium- and lithium-based greases are widely used. Many other metallic soaps are also useful, including those of aluminium, sodium, and mixtures of them. Such soaps are also used as thickeners to increase the viscosity of oils. In ancient times, lubricating greases were made by the addition of lime to olive oil.

Milk and Honey (album)

Milk and Honey is an album credited to John Lennon and Yoko Ono released in 1984. It is Lennon's eighth and final studio album, and the first posthumous release of Lennon's music, having been recorded in the last months of his life during and following the sessions for their 1980 album Double Fantasy. It was assembled by Yoko Ono in association with the Geffen label.

Background

Milk and Honey was the duo's projected follow-up to Double Fantasy, though Lennon's death caused a temporary shelving of the project. It took Ono three years to be able to resume work to complete it. Ono's material largely comprises new recordings, which she undertook during the album's preparation in 1983, which give her songs a more commercial and contemporary edge. Conversely, Lennon's material, being rough takes and rehearsal recordings, has a more casual feeling.

Music and lyrics

"Nobody Told Me", a song Lennon had intended for Ringo Starr's 1981 Stop and Smell the Roses, was released as a single and became a worldwide Top 10 hit. Other singles from the album were "I'm Stepping Out" and "Borrowed Time". The songs "Let Me Count the Ways" and "Grow Old with Me" were written by Lennon and Ono to each other using inspiration from poems by Elizabeth Barrett Browning and Robert Browning. They are presented in their demo form.

Mystery meat navigation

Mystery meat navigation (also known as MMN) is a disparaging term coined in 1998 by Vincent Flanders, author and designer of the website Web Pages That Suck, to describe a web page where the destination of the link is not visible until the user points their cursor at it. Such interfaces lack a user-centered design, emphasizing aesthetic appearance, white space, and the concealment of relevant information over basic practicality and functionality.

The epithet "mystery meat" refers to the meat products often served in American public school cafeterias whose forms have been so thoroughly reprocessed that their exact types can no longer be identified by their appearances: like them, the methods of MMN are clear to the producer but baffling to the consumer.

Flanders originally and temporarily described the phenomenon as Saturnic navigation in reference to the Saturn Corporation, whose company website epitomized this phenomenon. Flanders writes, "The typical form of MMN is represented by menus composed of unrevealing icons that are replaced with explicative text only when the mouse cursor hovers over them".

Gummy bear

A gummy bear (German: Gummibär) is a small, fruit gum candy, similar to a jelly baby in some English-speaking countries. The candy is roughly 2 cm (0.8 in) long and shaped in the form of a bear. The gummy bear is one of many gummies, popular gelatin-based candies sold in a variety of shapes and colors.

History

The gummy bear originated in Germany, where it is popular under the name  Gummibär  (gum or gummy bear) or in the endearing form  Gummibärchen  ([little] gum or gummy bear), gum arabic was the original base ingredient used to produce the gummy bears, hence the name gum or gummy. Hans Riegel, Sr., a confectioner from Bonn, started the Haribo company in 1920. In 1922, inspired by the trained bears seen at street festivities and markets in Europe through to the 19th century, he invented the Dancing Bear (Tanzbär), a small, affordable, fruit-flavored gum candy treat for children and adults alike, which was much larger in form than its later successor, the Gold-Bear (Goldbär). Even during Weimar Germany's hyperinflation period that wreaked havoc on the country, Haribo's fruit-gum Dancing Bear treats remained affordably priced for a mere 1 Pfennig, in pairs, at kiosks. The success of the Dancing Bear's successor would later become Haribo's world-famous Gold-Bears candy product in 1967.
