Plumbago was commonly used in its massive mineral form. Both of these names arise from confusion with the similar-appearing lead ores, particularly galena. The Latin word for lead is plumbum, which gave its name to both the English term for this grey metallic-sheened mineral and even the leadworts or plumbagos, plants with flowers that resemble this colour."
"The concept of phonons was introduced in 1932 by Russian physicist Igor Tamm. The name phonon comes from the Greek word φωνή (phonē), which translates as sound or voice because long-wavelength phonons give rise to sound."
"Lu thought that elements of New Yorker style were ridiculous; for instance, our habit of putting points in I.B.M. when I.B.M. itself had long since done without them, and of sticking a comma in Time, Inc., as if oblivious of the publisher’s own practice (and of the pun on “ink”). Yet there was no more zealous enforcer."
Here's a bit from that article: "Quoth the style book: “When alternatives are possible, use double ‘p’ in words like ‘kidnapped,’ double ‘s’ in words like ‘focussed,’ and double ‘l’ in words like ‘marvellous’ and ‘travelled.’” No kidnapper ever focussed so marvellously on this well-travelled territory."
"An illustration of how ultraviolet appears is provided by the Impressionist painter Claude Monet. Following cataract surgery in 1923, his colour palette changed significantly; after the operation he painted water lilies with more blue than before. This may be because after lens removal he could see ultraviolet light, which would have given a blue cast to the world."
"When the lens becomes opaque due to cataracts, it may be surgically removed, and can be replaced with an artificial lens. Even with the lens removed (a condition known as aphakia) the patient can still see, as the lens is only responsible for about 30% of the eyes' focusing power.
However, aphakic patients report that the process has an unusual side effect: they can see ultraviolet light. It is not normally visible because the lens blocks it. Some artificial lenses are also transparent to UV with the same effect. The receptors in the eye for blue light can actually see ultraviolet better than blue."
"Alum has been used at least since Roman times for purification of drinking water and industrial process water. Between 30 and 40 ppm of alum for household wastewater, often more for industrial wastewater, is added to the water so that the negatively charged colloidal particles clump together into "flocs", which then float to the top of the liquid, settle to the bottom of the liquid, or can be more easily filtered from the liquid, prior to further filtration and disinfection of the water."
"Historical natron was harvested directly as a salt mixture from dry lake beds in Ancient Egypt and has been used for thousands of years as a cleaning product for both the home and body. Blended with oil, it was an early form of soap. It softens water while removing oil and grease. Undiluted, natron was a cleanser for the teeth and an early mouthwash. The mineral was mixed into early antiseptics for wounds and minor cuts. Natron can be used to dry and preserve fish and meat. It was also an ancient household insecticide, was used for making leather and as a bleach for clothing.
The mineral was used in Egyptian mummification because it absorbs water and behaves as a drying agent. Moreover, when exposed to moisture the carbonate in natron increases pH (raises alkalinity), which creates a hostile environment for bacteria. In some cultures natron was thought to enhance spiritual safety for both the living and the dead. Natron was added to castor oil to make a smokeless fuel, which allowed Egyptian artisans to paint elaborate artworks inside ancient tombs without staining them with soot.
Natron is an ingredient for making a distinct color called Egyptian blue, and also as the flux in Egyptian faience. It was used along with sand and lime in ceramic and glass-making by the Romans and others at least until 640 AD. The mineral was also employed as a flux to solder precious metals together."
"n. A good fellow, in an emphatic sense: a term of admiration bestowed on one who on occasion or habitually shows in a modest way great or unexpected courage, kindness, or thoughtfulness, or other admirable qualities.
n. “In brief I don't stick to declare Father Dick, So they called him for short, was a regular brick; A metaphor taken, I have not the page aright, Out of an ethical work by the Stagyrite.”

"Girdle books were small portable books worn by medieval European monks, clergymen and aristocratic nobles as a popular accessory to medieval costume, between the 13th and 16th centuries. They consisted of a book whose leather binding continued loose below the cover of the book in a long tapered tail with a large knot at the end which could be tucked into one's girdle or belt. The knot was usually strips of leather woven together for durability. The book hung upside down and backwards so that when swung upwards it was ready for reading. The books were normally religious: a cleric's daily Office, or for lay persons (especially women) a Book of Hours. One of the most well known texts to become a girdle book is Boethius's Consolation of Philosophy, although it is the only surviving philosophical/theological girdle book."
I knew she plays the sax. Have you read 'Crazy Brave' yet?
I wonder how many people realize the etymological significance of the title.
Playing the sax is 'crazy brave' of course.
The sax is the ultimate soul instrument with its long neck and throaty sound (see nephesh)
My niece Ramona has taught me that well!
She has 'crazy brave' in her blood, too.
kumanan brought it to my attention that the palindrome code was not ignoring spaces, so I fixed it. You'll be seeing "And it's a palindrome" on multi-word palindrome pages by the end of the day. In the interim, here's a list to celebrate to new feature: http://www.wordnik.com/lists/semordnilap
