Robert Liston, MD
He was a Scottish speed surgeon during the
1800s. In one case, he amputated a leg in less than 2.5 minutes (the patient died afterward
from gangrene). He amputated, in error the fingers of his young
assistant (who died afterward from gangrene). He also slashed
through the coat tails of a distinguished surgical spectator, who
was so terrified that the knife had pierced his vitals he dropped
dead from fright. It was the only operation in history with a 300
percent mortality.
SUV vs. Crossover
A crossover is based on a car's platform,
while an SUV uses the chassis of a truck. The result is that
crossovers use "unibody" architecture, meaning the body and frame
are one piece, while SUVs use a "body on frame" design, meaning the
body is built separate from the frame.
SUV is often applied to both crossovers and SUVs. In the past, that was even more common. Before, SUV brought up negative associations with large size and poor gas mileage. That is when many automakers started using the term "crossover" to describe a vehicle that was "crossing over" from the practicality of an SUV to the drivability and fuel efficiency of a car.
Many vehicles, such as the Explorer, Highlander, Grand Cherokee, Nissan Pathfinder, Lexus RX, and Acura MDX are technically crossovers.
The Chevrolet Tahoe, Ford Expedition, and Mercedes G-Class are all SUVs in the original sense of the term.
If you are unsure whether a vehicle uses a car-based unibody design or body-on-frame construction, it is safe to use the term SUV. That acronym is still used to describe nearly anything with available all-wheel drive and raised ground clearance.

Eyelash Facts
A study published in the Journal of
the Royal Society Interface reports that eyelashes divert airflow to
prevent drying of the eyes and protect against airborne
particulates.
Twenty two species of mammals possess eyelashes of a length one-third the eye width. Wind tunnel experiments confirm that this optimal eyelash length reduces both deposition of airborne particles and evaporation of the tear film by a factor of two. This happens because of the incoming flow's interactions with both the eye and eyelashes.
Another study found that growth of eyelashes occurs in response to exposure to allergens. Children with allergies have ten percent longer and denser lashes than those without allergies. Allergens trigger mast cells within the inside of the eyelid to release prostaglandins that promote hair growth, which presumably protects the eye. If models only knew their long lashes make them look like they have allergies.

90-Mile Beach
It appears, New Zealand might be stretching the
facts a bit. New Zealand's 90-Mile Beach is only 55 miles long. Back
when missionaries traveled on horseback a horse could travel on
average about 30 miles (50 km) in a day before needing to be rested.
The beach took three days to travel therefore earning its name.
However, the missionaries did not take into account the slower pace
of the horses walking in the sand, thus thinking they had traveled
about 90 miles (140 km) when in fact they had traveled just 55
(88km).
Eye Colors, Grey
The exact causes of grey eyes are a bit
uncertain, but there is a possibility that it is the eyes having
more collagen and less melanin than blue eyes. As a result, when
light enters the eye it is scattered slightly different, causing
them to look grey, rather than blue.
Those with grey eyes are generally believed to have strong characters, with a dominant, rational, analytic mindset.
Grey eyes are most commonly found in Northern and Eastern areas of Europe. They can also be found at various locations around the world, including North West Africa, Asia, and the Middle East.
Incidentally, Gray and grey are different spellings of the same word, and both are used throughout the English-speaking world. Gray is more common in American English, while grey is more common in all other varieties of English.

Millions of Lakes
There are 117 million lakes on Earth,
covering 3.7 percent of the continental land surface. This does
not include Antarctica, Greenland, or the Caspian Sea. About 90
million of these lakes are less than two football fields in size,
or 0.5 to 2.5 acres (0.2 to 1 hectares).
Weekday Name Origins
Sunday has been set aside as the “day
of the sun” since ancient Egyptian times in honor of the sun-god Ra.
The Egyptians passed their idea of a 7-day week onto the Romans, who
also started their week with the Sun’s day, dies solis. When
translated into early German, the first day was called sunnon-dagaz,
which made its way into Middle English as sone day. For some in the
Christian tradition, the first day of the week is named in
accordance with the creation tale in the first book of the Bible,
Genesis, where one of the first things God did was say “let there be
light, and there was light.” Not every culture has Sunday as its
first day, and notable exceptions are found in the Slavic languages,
where Sunday is the last day of the week and is not named in honor
of the sun. For example, in Hungary, Sunday is called Vasárnap and
means market day, and in old Russian, where Sunday was sometimes
called free day.
Monday was named after the moon. In Latin, it was known as dies lunae (day of the moon), and this made its way into Old English as mon(an)dæg and the monday in Middle English. In early pagan traditions, Monday was dedicated to the goddess of the moon, although in some Christian traditions, assigning the moon to the second day also follows the story of Genesis, where in between the first and second days, darkness was separated from light and “evening came.”
Tuesday has always been dedicated to a war god, and in ancient Greek, it was known as hemera Areos (day of Ares), modified only slightly by the Roman dies Martis (day of Mars), and later in Old English Tiwesdæg, in honor of a Norse god of war and law, Tiwaz or Tiw.
Wednesday was dedicated to the messenger of the gods, and for the Greeks, it was known as hemera Hermu (day of Hermes), then to the Romans as dies Mercurii (day of Mercury). When it was adopted by the Anglo-Saxons, as Mercury’s areas of expertise overlapped with his, they dedicated the day to Odin, Woden in Old English (calling the day wodnesdæg).
Jupiter was awarded the fifth day, dies Jovis, by the Romans, and it was assigned to Thor by the Norse, where it was originally called thorsdgr, later modified by Old English into thurresdæg, and then into Middle English’s thur(e)sday.
Friday was assigned to Aphrodite and Venus, in Latin dies Veneris. In Old Norse and English, Venus was associated with Frigg, a goddess of knowledge and wisdom. By Old English, the day’s name had been modified into frigedæg (Frigg’s day) and by Middle English, to fridai. TGIF, for Thank God It’s Friday, dates back to 1946.
Saturday historically was dedicated to Saturn or Cronus to the Greeks, Jupiter’s father and a god associated with dissolution, renewal, generation, agriculture and wealth. In Latin, the day was originally called dies Saturni, which was transformed into sæter(nes)dæg in Old English and saterday in Middle English. For some religions, Saturday is celebrated as the weekly day of rest, known as the Shabbat in Judaism and Sabbath for Seventh Day Adventists.

Deepweb and Darknet
These two words are often spoken by
the news media and we hear them on some TV shows, but they are never
explained.
The Deepweb refers to part of the Internet, specifically the world wide web (anything that starts www) that isn't indexed by search engines, and can't be accessed by Google.
The Darknet refers to non-www networks, where users may need separate software to access them. For example, Silk Road and many illicit markets are hosted on Darknet networks like I2P and Tor.

Amazon May Print Your Product
Amazon plans to create and
patent 3D-printing delivery trucks. The patent, called 'Providing
Services Related to Item Delivery via 3D Manufacturing on Demand',
describes an effort to deliver 3D printed items manufactured on a
truck to customers.
3D printing is a process, which three dimensional objects can be printed on demand.
The 3D printing trucks that Amazon is proposing will double as delivery trucks. The patent lays out a sequential series of steps in regards to how this process will likely happen: first, a customer places an order, the 3D printable order is sent to the delivery truck closest to the customer, and the item is produced en route and delivered once complete.
The patent also covers subtractive printing, which is the process of taking a block of material, usually metal and removing pieces in order to obtain the desired shape.

Rabbits and Hares
Rabbits and hares are often confused with
one another. Rabbits and hares do not breed with one another in
their natural habitats. Jackrabbits are a type of hare.
From the moment they are born, rabbits and hares are easily distinguished. Baby rabbits, called kittens, are born blind and furless. They are unable to move around much on their own and are weak. Baby hares, called leverets are born with their fur and their eyes open. A baby hare explores its new world shortly after birth.
Rabbits are more social and when they are in the wild they prefer to share their burrows with other members of their colony. They sleep in their burrows during the day, hiding from potential predators. If mother rabbit needs to leave her kittens, she will cover them up with fur and leaves to keep them warm and safe.
Each group of rabbits tends to have a dominant male that gets to mate with the majority of the females. Rabbits prefer softer foods, such as grass and vegetables. Rabbits have been domesticated while hares have not.
Hares are generally larger, lithe, wiry, and have larger back legs and paws. Their ears are longer, and stick straight up from the head. Usually, a hare’s ears will have black markings. Additionally, hares usually change color according to season; they are grayish brown in spring, summer, and fall, and turn white in the winter. A hare’s skull is slightly different in shape to a rabbit’s skull.
Hares prefer to live alone, coming together only to mate (with little contention among males over mating rights), and usually make their homes in nests among tall grasses rather than dig a burrow. They also are not afraid to leave their leverets just hours after the babies are born. Baby hares are well equipped to living without their mothers at just an hour old. Hares are more likely to choose harder foods like bark and twigs.

Satellite Orbits
The reason we do not hear about satellites
bumping into each other is because they each have their own
protected orbit, kind of like a one lane highway. Orbits aren't
patented, but “useful systems which incorporate particular orbits,
such as technological solutions for providing telecommunications
which utilize equipment in those orbits, are patent-eligible.”
So while a company couldn't attempt to patent a specific set of gravitational dynamics, it could exert control over an orbit by patenting the specific set of innovations needed to keep a satellite in that orbit.
US Patent No. 5,410,728, was issued to Motorola, and outlines how a formation of several satellites can optimize cellular coverage. The satellite orbit is not subject to this patent, but the process of deploying them into those orbits for some use as telecommunications is patented.
Incidentally, Sci-Fi author Arthur C. Clarke wrote about patenting orbits way back in 1945. The geostationary orbit he proposed that year is now home to hundreds of satellites, and has been officially designated the Clarke orbit by the International Astronomical Union.
