Gibralter
A British Overseas Territory; not uninhabited; and certainly not an island.

caprice
caprice (n.)

‘originally “a shivering,” a word of uncertain origin. Some guesses … or that the Italian word is connected with capo “head” + riccio “curl, frizzled,” literally “hedgehog” (from Latin ericius). The notion in this case would be of the hair standing on end, hence a person shivering in fear.’

refugium
refugium (n.)

In biology, a refugium (plural: refugia) is a location which supports an isolated or relict [see next entry] population of a once more widespread species.

relict
relict (n.)

“a widow,” mid-15c., relicte, etymologically “one who is left, one who remains,” … also as an adjective in Middle English and early modern English, originally “left undisturbed or untouched, allowed to remain” (mid-15c.) but used in various senses.

Alba
Alba (n.)

Alba is the Scottish Gaelic name for Scotland. Historically, the term refers to Britain as a whole and is ultimately based on the Indo-European root for “white”.

Mineola, Texas
Mineola is a city in the U.S. state of Texas in Wood County.

The town was incorporated as the railroads arrived in 1873. A railroad official, Ira H. Evans, combined the names of his daughter, Ola, and her friend, Minnie Patten, to create the city name Mineola.

electrolysis
The word “lysis” means to separate or break; therefore, electrolysis is more or less “breakdown via electricity”.

bacteriophage
Bacteriophages are among the most common and diverse entities in the biosphere. Bacteriophages are ubiquitous viruses, found wherever bacteria exist.

In 1896, Ernest Hanbury Hankin reported that something in the waters of the Ganges and Yamuna rivers in India had a marked antibacterial action against cholera and it could pass through a very fine porcelain filter.

Félix d’Hérelle announced on 3 September 1917, that he had discovered “an invisible, antagonistic microbe of the dysentery bacillus”. D’Hérelle called the virus a bacteriophage, a bacteria-eater (from the Greek phagein meaning “to devour”). D’Herelle researched bacteriophages and introduced the concept of phage therapy.

serve-and-volley
The serve-and-volley style of play has diminished in recent years with advances in racquet and string technologies which allow players to generate a great amount of top spin on groundstrokes and passing shots. The slowing of court surfaces and deflation of balls, promoting longer rallies for the enjoyment of spectators, has also devalued the serve-and-volley style.

loophole
The first records of loophole come around 1585. It combines loop, meaning “something folded on itself, leaving an opening between parts,” with hole, meaning “an opening.” Originally loophole referred to holes in castles or forts that archers could shoot arrows through.arrowslit: (often also referred to as an arrow loop, loophole or loop hole, and sometimes a balistraria, is a narrow vertical aperture in a fortification through which an archer can launch arrows or a crossbowman can launch bolts.

(More) exactly how the Moon affects the tides and why there are two tidal cycles per lunar day
“However, inertia — the tendency of a moving object to keep moving — affects the earth’s oceans too. As the moon circles the earth, the earth moves in a very slight circle too, and this movement is enough to cause a centrifugal force on the oceans.

This inertia, or centrifugal force, causes the oceans to bulge on the opposite side facing the moon. While the moon’s gravitational pull is strong enough to attract oceans into a bulge on the side of the earth facing the moon, it is not strong enough to overcome the inertia on the opposite side of the earth. As a result, the world’s oceans bulge twice once when they are on the side of Earth closest to the moon, and once when they are on the side farthest from the moon, according to the Wood’s Hole Oceanographic Institution in Wood’s Hole, MA.

Geography complicates the tides, but many places on Earth experience just two high and two low tides every 24 hours and 50 minutes. (The extra 50 minutes is caused by the distance the moon moves each day as it ‘orbits’ Earth).”

And a more general example of a barycenter …

oral exam
After my teeth cleaning treatment, the dental hygienist asked if I had any questions.

I asked “Is plaque mineral or organic ?”

She gave a thorough answer — mentioned that the first layer on the teeth is called biofilm and that this changes to tartar over time.

I was intrigued by the word ‘biofilm’ and I went down the rabbit hole.

Excerpt from wiki

Dental plaque is a biofilm of microorganisms (mostly bacteria, but also fungi) that grows on surfaces within the mouth. It is a sticky colorless deposit at first, but when it forms tartar, it is often brown or pale yellow. It is commonly found between the teeth, on the front of teeth, behind teeth, on chewing surfaces, along the gumline (supragingival), or below the gumline cervical margins (subgingival). Dental plaque is also known as microbial plaque, oral biofilm, dental biofilm, dental plaque biofilm or bacterial plaque biofilm. Bacterial plaque is one of the major causes for dental decay and gum disease.

hypocoristic / hypocorism

It may be a pet name, a “name used to show affection for a person or object. It may be a diminutive form of a person’s name, such as Izzy for Isabel or Bob for Robert, or it may be unrelated.”

“It evolved from the Greek verb hypokorizesthai (“to call by pet names”), which itself comes from korizesthai (“to caress”).”

Combined system

Most of the UK has a combined sewage system, so wastewater from toilets is carried to sewage treatment works through the same pipes as rainwater.

To prevent homes and public spaces being flooded after heavy rains, the system is designed occasionally to overflow and discharge untreated sewage into rivers and the sea.

The Mohole project never got to second base

After a successful Phase 1 in 1961 off Guadalupe Island in the Pacific Ocean, the Mohole project devolved due to mismanagement, cost overruns, and scientific disagreement and was defunded in 1966. The deepest hole drilled was only to 601 feet (183 m) below the sea floor in 11,700 feet (3,600 m) of water.

The deepest hole ever drilled was the Kola Superdeep Borehole in Russia (near the Artic Ocean and near Finland), a depth of 12,262 meters (7.6 miles *) was reached in 1989.

* A large egg has an average diameter of about 43 mm and an average shell thickness of about 0.3 mm; if the egg would be scaled up to the diameter of the Earth, about 7920 miles, then the egg shell would be 55 miles thick. This means the drilling of 7.6 miles would represent only about 14% of the scaled egg shell thickness.

celerity
Swiftness, rapidity of motion

The rattlesnake scored the highest measured acceleration, at 279 meters per second squared. But to their surprise, the nonvenomous rat snake came in a close second at 274 meters per second squared (275 meters per second squared = 28 Gs !).

Snakes probably evolved such quick strikes to compete with the reaction times of prey, Penning adds. Depending on the species and the situation, mammals can react and make an observable motion anywhere between 60 and 395 milliseconds. An average human eye blink, for instance, spans a leisurely 200 milliseconds.

automorphic function
“The sine function is a basic example of what we mathematicians more generally call an automorphic function: When we change (morph) a variable by some process (in this case, sliding over by 2π), the function turns back into itself (hence “auto” morphic).”

excelsior
Wood wool, known primarily as excelsior in North America, is a product made of wood slivers cut from logs. It is mainly used in packaging, for cooling pads in home evaporative cooling systems known as swamp coolers, for erosion control mats, and as a raw material for the production of other products such as bonded wood wool boards. In the past it was used as stuffing, or padding, in upholstery, or to fill stuffed toys. It is also sometimes used by taxidermists to construct the armatures of taxidermy mounts.”

Naming of Montpelier
“using French names was popular at that time because of the help the United States received from the French government in winning the Revolutionary War”

EXCERPT

Daniel P. Thompson in his “History of the Town of Montpelier … laments the way settlers renamed rivers and mountains instead of adopting aboriginal names. In 1860 he wrote, “I cannot forbear, in passing, to express a regret that the practical tastes and common-place notions of our first settlers should have so far governed them, in respect to this name, as to have led them generally to adopt the homely translation instead of the poetic original. The Indian names are not like most of ours, arbitrary and inexpressive, but ever have their significations. This of itself is a beauty. It ensures, also, the applicability of the name to the thing.” For this reason, Thompson joined a group fighting to keep the name of Montpelier’s dominant river “Winooski” — Abenaki for “land of the wild onion.”

Eggs are single cells !

EXCERPT

What most people perhaps don’t realize is that eggs are single cells. Even a chicken egg is one cell — a really, really large cell. It’s incredibly hard to make a cell that size — and not something that can be done alone. To become that large, the egg grows while remaining physically connected to other cells, which are called sister cells or nurse cells.

At the Flatiron Institute, developmental biologist Jasmin Imran Alsous and her collaborators are working together to uncover the mysteries of how gametes move and develop.

EXCERPT

The saros is a period of exactly 223 synodic months, approximately 6585.3211 days, or 18.029 years, that can be used to predict eclipses of the Sun and Moon. One saros period after an eclipse, the Sun, Earth, and Moon return to approximately the same relative geometry, a near straight line, and a nearly identical eclipse will occur, in what is referred to as an eclipse cycle. A sar is one-half of a saros.

nickel allergy
There is a label on the frame of my new glasses ‘no nickel allergy’, so I looked it up.
EXCERPT

The exact cause of nickel allergy is unknown. As with other allergies, nickel allergy develops when your immune system views nickel as a harmful, rather than a harmless substance. Normally, your immune system only reacts to protect your body against bacteria, viruses, or toxic substances.

Once your body has developed a reaction to a particular agent (allergen) — in this case, nickel — your immune system will always be sensitive to it.

We Do Repairs

MSM never intended to be in competition with the retail computer industry, so we do not advertise a repair service… but we do repairs!

We understand that many families struggle to make ends meet. Families also know that having technology for their children is essential for academic success. With this in mind, MSM repairs units for needy families. If an MSM computer needs repair, it is of course – free. If we repair a computer that has been purchased elsewhere, we charge only the cost of the parts or licenses needed to repair the unit. No labor time is charged.

MSM takes pride in our business ethic. We never fix a computer that isn’t worth repairing – and we never deem a computer to be salvaged when it can be repaired and continue to service a family successfully.

If you have a computer issue – come see us! We’ll check it out for free!

https://www.mustardseedcomputers.com/we-do-repairs/

EXCERPT

FREE … For Sale … Lifetime Warranty!
First, all students from 5th grade through college are eligible for a free computer from MSM! Here’s How…

5th -8th graders … write a short essay stating why they think a computer will help them with their school work. Plus, they complete 10 hours of community service. The 10 hours can be completed ANYWHERE. We hope that our students will find new and inventive ways to complete their service: maybe help an elderly neighbor, volunteer at a shelter, organize a service project with their friends at church, etc.

After these two steps are completed, the student brings to MSM the paperwork and they leave with their new computer! It’s FREE!

Second, MSM does some fundraising by selling high-end computers and laptops. We sell every name brand and can build a unit to your specs. Many of our units have Intel i7 processors with plenty of RAM. And every unit comes with Windows 10 Pro, Office Pro, and lots of other ‘goodies’. Computers start at $100! Our most expensive unit is $200! The awesome thing about our refurbished computers is that they have a lifetime warranty! Hardware and software are repaired or reloaded for free if they fail in any way. (Abuse or natural disasters are not covered.)

The lifetime warranty is also a feature of our student units. Kids can be hard on computers – we know that they are just learning and may do some unexpected things to their computers. Since we want our kids to ALWAYS have a usable computer for school work – we warrant them for life. We also have free upgrades! When middle schoolers move up to high school – they trade in their unit for a new and faster unit … when they go to college – they get another upgrade and also have the option for a laptop. It’s all FREE!

How Airplanes Fly
EXCERPT

Almost everyone today has flown in an airplane. Many ask the simple question “what makes an airplane fly”? The answer one frequently gets is misleading and often just plain wrong. We hope that the answers provided here will clarify many misconceptions about lift and that you will adopt our explanation when explaining lift to others. We are going to show you that lift is easier to understand if one starts with Newton rather than Bernoulli. We will also show you that the popular explanation that most of us were taught is misleading at best and that lift is due to the wing diverting air down.

Harry James — Beaumont days
Excerpt from wiki

James started taking trumpet lessons from his father at age eight, and by age twelve he was leading the second band in the Christy Brothers Circus, for which his family was then working. James’s father placed him on a strict daily practice schedule. At each session he was given several pages to learn from the Arban’s book and was not allowed to pursue any other pastime until he had learned them. While still a student at Dick Dowling Junior High School, he participated as a regular member of Beaumont High School’s Royal Purple Band, and in May 1931 he took first place as trumpet soloist at the Texas Band Teacher’s Association’s Annual Eastern Division contest held in Temple, Texas.

In 1924, his family settled in Beaumont, Texas. It was here in the early 1930s that James began playing in local dance bands when he was 15 years of age. James played regularly with Herman Waldman’s band, and at one performance was noticed by nationally popular Ben Pollack. In 1935 he joined Pollack’s band, but left at the start of 1937 to join Benny Goodman’s orchestra, where he stayed through 1938. He was nicknamed “The Hawk” early in his career for his ability to sight-read. A common joke was that if a fly landed on his written music, Harry James would play it. His low range had a warmth associated with the cornet and even the flugelhorn, but this sound was underrecorded in favor of James’ brilliant high register.

Linda Ronstadt
Excerpt

Linda Ronstadt was born in 1946 in Tucson, Arizona, to Gilbert Ronstadt, a prosperous machinery merchant who ran the F. Ronstadt Co. hardware store. Her mother, Ruth Mary Copeman, from the Flint, Michigan area, was the daughter of Lloyd Groff Copeman, a prolific inventor and holder of nearly 700 patents, among them, an early form of the microwave oven and a flexible ice cube tray, the latter earning millions in royalties. Linda’s father came from a pioneering Arizona ranching family and was of German, English, and Mexican descent, and also a guitarist who sang Mexican songs to his children. Linda was raised on the family’s ten-acre ranch in Tucson along with three siblings. She had a pony and later a horse. As a teen, she formed a folk trio with brother Peter and sister Suzy; calling themselves the New Union Ramblers.
