A gospel (from Old English, gōd spell "good news")
is a writing that describes the life of Jesus. The word is primarily used to
refer to the four canonical gospels: the Gospel of Matthew, Gospel of Mark,
Gospel of Luke and Gospel of John, probably written between AD 65 and 80. They
appear to have been originally untitled; they were quoted anonymously in the
first half of the second century (i.e. 100 - 150) but the names by which they
are currently known appear suddenly around the year 180. The first canonical
gospel written is thought by most scholars to be Mark (c 65-70). (Wikipedia,

Dolphins can stay constantly alert for more than two weeks
Dolphin (aquatic mammal), fast-swimming mammal belonging to
the order Cetacea, which also includes whales and porpoises. Sleek and powerful
swimmers, dolphins are found in seas throughout the world; some inhabit
freshwater rivers and lakes. Characteristic features of most dolphins are long
snouts with rows of sharp teeth, and rounded foreheads with a nostril on top,
known as the blowhole.
There are at least 40 species of dolphins. Dolphins resemble
fish in many ways, but they exhibit a number of true mammalian characteristics:
They are warm-blooded, breathe air, and nurse their young on milk. Dolphins and
porpoises have a similar appearance, but dolphins can be distinguished from
porpoises by their more prominent snouts and conical teeth. Porpoises have
blunt snouts, chisel-shaped teeth, and a stouter body than dolphins.
Sailors have long considered the presence of dolphins
cruising alongside the bows of ships as a good omen and a promise of fair
weather. Dolphins also figure prominently in folklore, often appearing in works
of art, on coins and currency, and on stamps. Ancient Greek coins depicted the
son of Poseidon seated on a dolphin, and the ancient Roman author Pliny the
Elder wrote a story of a dolphin that carried a poor man's son to school each
day. Many classical writers described how dolphins harnessed to chariots helped
maidens in distress. A dolphin was on the coat of arms of the dauphin, the
title given the eldest son and heir of the king of France.

Early Music -- during ancient Greek and Roman empires (500 B.C. to 300 A.D.)
The first European music is that of the ancient Greeks and Romans,
dating from roughly 500 B.C. to A.D. 3OO. Fewer than a dozen examples of Greek
music from this period, written in an alphabetical notation, survive. Ancient
Greek philosophers believed that music originated from the god Apollo, as well
as from the mythological musician Orpheus and other divinities. They also
believed that music reflected in microcosm the laws of harmony that rule the universe,
and that music influenced human thought and actions.
The Greek philosopher Pythagoras (ca. 580 B.C.-ca. 500 B.C.)
discovered the mathematical relationships between specific frequencies and musical inrervals, using a single-string
instrument (called a monochord) to produce the various intervals. For example, two
notes whose frequencies form a ratio of 2:1 sound one octave apart; a ratio of 3:2 forms an interval of a fifth, and a ratio of 4:3 forms a fourth. These basic intervals combine
to create the modes and scales on which all Western melodies and harmony are based.

How many hairs does the average person have on his or her head and how much does human hair grow in a year?
The
amount of hair covering varies from one individual to another. An average person
has about 100,000 hairs on their scalp. Most redheads have about 90,000 hairs, blonds
have about 140,000, and brunettes fall in between these two figures. Most people
shed between 50 to 100 hairs daily. Each hair grows about 5 inches (12.7 centimeters)
every year. (The Handy Science Answer Book, compiled by the Science and

Can a person get a suntan through a window?
No. The
ultraviolet radiation that causes suntan does not pass through glass. A tan is the
skin 's natural defense against these harmful sun rays. Pigment cells in the
lower skin level make more pigment and melanin to absorb the ultraviolet rays. As
the pigment spreads into the
top layer of the skin, it becomes darker. (The Handy Science Answer Book,
compiled by the Science and Technology department of the Carnegie Library of

The original meaning of the word “scapegoat”
As described in Leviticus 16:1-27, part of a Hebrew ritual on
the Day of Atonement involved the
presentation of two male goats at the altar of the tabernacle. After lots were cast,
one goat was sacrificed to the Lord; the other, the ‘scapegoat’,
was set aside for Azazel, an evil spirit of the wilderness. The high priest
transferred the sins of the people onto this goat and sent it away into the desert.

What to do when you get sick -- making the right decisions
When you get sick, you must decide what course of action to take in
order to recover your health. If you do not accept this responsibility, others will decide for you and will not
necessarily make the best choices. The most important decision is whether
visits to health professionals will help or hinder your own healing system. You
will need to understand the nature of your illness and to know whether conventional
medicine can do anything for it without reducing the possibility of spontaneous
healing. You will also want to know whether any alternative treatments exist that
might be of benefit.
A good place to start is with a review of what conventional medicine
can do
effectively and what it cannot. For example, it is very effective at managing trauma, so
that if I were in a serious automobile accident, I would want to go directly to
an urgent care facility in a modem hospital,
not to a shaman, guided imagery therapist, or acupuncturist. (Once out of
danger, I might use those other resources to speed up the natural healing process.)
Conventional medicine is also very good at diagnosing and managing crises of
all sorts: hemorrhages, heart attacks, pulmonary edema, acute congestive heart
failure, acute bacterial infections, diabetic comas, bowel obstructions, acute
appendicitis, and so forth. You must be able to recognize symptoms of
potentially serious conditions, so that you will not waste time before
getting needed treatment. In general,
symptoms that are unusually severe, persistent,
or out of the range of your normal experience warrant immediate investigation.

Color Blindness
Color blindness is a defect of vision affecting the ability
to distinguish colors, occurring mostly in males. It involves a person’s inability
to distinguish one or more of the three colors red, green, and blue. It is
noteworthy to know that the ability to see color exists in only a few
vertebrates, including, among others, man and the other primates, fish,
amphibians, some reptiles, and some birds; and in bees and butterflies.
The first detailed report on this condition was written by the
British chemist John Dalton, who was himself afflicted with it. Total color
blindness, in which all hues are perceived as variations of gray, is known as
achromatopsia or monochromatism. This condition is congenital, extremely rare,
and affects men and women almost equally. Partial color blindness, called
dichromatism, consists generally of the inability to differentiate between the
reds and the greens or to perceive either reds or greens; infrequently, the
confusion may involve the blues or the yellows. Dichromatism is the most common
form of color blindness, affecting about 7 percent of men and less than 1
percent of women. Dichromatism is identified as a sex-linked hereditary
characteristic. Color blindness also may occur as a temporary condition following
a serious illness.

Heavy Water
Heavy water contains heavy hydrogen, or deuterium, instead
of normal hydrogen. Deuterium is the
stable, nonradioactive isotope of hydrogen with atomic weight 2.01363 and
symbol D, or 2H. It is commonly called heavy hydrogen because its atomic weight
is approximately double that of ordinary hydrogen, but it has identical
chemical properties. Deuterium has about twice the atomic weight of normal
hydrogen because its nucleus contains a proton and a neutron, instead of just a
proton. Hydrogen as it occurs in nature contains approximately 0.02 percent of
deuterium. The boiling point of deuterium is -249.49° C (-417.08° F), or 3.28°
C (5.90° F) higher than that of ordinary hydrogen. Heavy water (deuterium
oxide, D2O) boils at 101.42° C (214.56° F) as compared to 100° C (212° F), the
boiling point of ordinary water. It freezes at 3.81° C (38.86° F) as compared
to 0° C (32° F) for ordinary water. Its density at room temperature is 10.79
percent greater than that of ordinary water.
Deuterium, which was discovered by the American chemist
Harold Urey and his associates in 1932, was the first isotope to be separated
in a pure form from an element. Several methods have been used to separate the
isotope from natural hydrogen. The two processes that have been most successful
have been fractional distillation of water and a catalytic exchange process
between hydrogen and water. In the latter system, when water and hydrogen are
brought together in the presence of a suitable catalyst, about three times as
much deuterium appears in the water as in hydrogen. Deuterium has also been
concentrated by electrolysis, centrifuging, and fractional distillation of
liquid hydrogen.

Book of the Dead
The name generally given to a large collection of funerary
texts of various dates, containing magical formulas, hymns, and prayers
believed by the ancient Egyptians to guide and protect the soul (Ka) in its
journey into the region of the dead (Amenti). Egyptians believed that the
knowledge of these texts enabled the soul to ward off demons attempting to
impede its progress, and to pass the tests set by the 42 judges in the hall of
Osiris, god of the underworld. These texts also indicated that happiness in the
afterlife was dependent on the deceased's having led a virtuous life on earth.
The earliest religious (funerary) texts known were found cut in hieroglyphs on
the walls inside the pyramids of the kings of the 5th and 6th Dynasties of the
Old Kingdom; these became known as the Pyramid Texts. A famous example is found
in the pyramid of Unas (reigned about 2356-2323 BC), the last king of the 5th
Dynasty. In the first Intermediate Period and in the Middle Kingdom private
individuals had these texts painted on coffins, from which the alternate name
Coffin Texts is derived. By the 18th Dynasty the texts were inscribed on papyri
placed in the mummy case; these papyri were frequently from 15 to 30 m (50 to
100 ft) long and illustrated in color.

Solar-terrestrial effects
Besides providing light and heat, the Sun affects the Earth
through its ultraviolet radiation, the steady stream of the solar wind, and the
particle storms of great flares. The near-ultraviolet radiation from the Sun
produces the ozone layer, which in turn shields the planet from such radiation.
The soft (long-wavelength) X rays from the solar corona produce those layers of
the ionosphere that make short-wave radio communication possible. The harder
(shorter-wavelength) X-ray pulses from flares ionize the lowest ionospheric
layer, producing radio fadeouts. The Earth's rotating magnetic field is strong
enough to block the solar wind, forming the magnetosphere, around which the
solar particles and fields flow. On the side opposite to the Sun, the field
lines stretch out in a structure called the magnetotail. When shocks arrive in
the solar wind, a short, sharp increase in the field of the Earth is produced.
When the interplanetary field switches to a direction opposite the Earth's
field, or when big clouds of particles enter it, the fields in the magnetotail
reconnect and energy is released, producing the aurora borealis (northern
lights). Big flares or coronal mass ejections bring clouds of energetic
particles that form a ring current around the magnetosphere, which produces
sharp fluctuations in the Earth's field called geomagnetic storms. These
phenomena disturb radio communication and produce voltage surges in
long-distance transmission lines and other long conductors.

The Splice of Life
![]() |
Dr. James Watson, left, and Dr. Francis Crick with their
Nobel Prize-winning model of the DNA molecule
|
Genetic engineering is the process that inserts genes from
one living organism into the cells of another, thereby custom-tailoring them to
do work they weren't designed for. For example, thanks to genetic engineering,
or recombinant-DNA technique, millions of bacteria are kept busy churning out
precious human insulin. Scientists built the micro-factories by slipping the
human gene responsible for the creation of insulin into E. coli, a mild-mannered bacterium
found in our intestinal tract. So far, genetic engineering has been most
successful with microorganisms, plants, mice (whose immune systems have been made
to mimic those of human beings), and-Stephen King, take note -- livestock: pigs
that gain weight faster, cows that give more milk. Science is still working on the problem of
getting genetically altered DNA back into a human cell and, we're told, isn't
even close to a solution. Someday, however, we may be able to replace or repair
bad genes, like the ones responsible for such diseases as cystic fibrosis,
sickle-cell anemia, and perhaps even cancer.

Strategic minerals
Strategic
minerals are minerals essential to the national defense -- the supply of which a
country uses but cannot produce itself. 33% to 50% of the 80 minerals used by industry could be classed as
strategic minerals. Wealthy countries, such as the United States, stockpile
these minerals to avoid any crippling effect on their economy or military strength
if political circumstances were to cut off their supplies. The United States,
for instance, stockpiles bauxite (14.5 million tons), manganese (2.2 million tons), chromium (1.8 million tons), tin (185,000 tons), cobalt (19,000 tons), tantalum (635 tons), palladium (1.25 million troy ounces), and platinum (453,000 troy ounces). (The Handy Science

Electron Microscope
A microscope that uses electrons instead of visible light to
produce highly magnified images of objects. Scientists use electron microscopes
in many different fields of research, including medicine, biology, chemistry,
metallurgy, entomology (the study of insects), and physics. Since its
introduction in the 1930s, the electron microscope has revolutionized the study
of microscopic structures and surfaces. See also Microscope.
Microscopes can only resolve structures that are larger than
the length of the waves (such as light waves) reflecting off of them. Electron
microscopes are able to obtain much higher powers of magnification than
standard visible light microscopes because electrons have much shorter
wavelengths associated with them than light waves. The highest magnification
achievable with light microscopes is about 2,000X (times); modern electron
microscopes can achieve magnifications approaching 1,000,000X.
Their invention
The invention of the electron microscope was made possible
by a number of theoretical and experimental advances in physics and
engineering. The main concept on which the electron microscope is founded—that
electrons have a wavelike nature—was hypothesized by French physicist Prince
Louis Victor de Broglie in 1923 (see Quantum Theory). In 1927, de Broglie’s
hypothesis was experimentally verified by American physicists Clinton J.
Davisson and Lester H. Germer, and independently by English physicist George
Paget Thomson. In 1932 German engineers Max Knoll and Ernst Ruska built the
first transmission electron microscope. In 1938 Ruska and German engineer Bodo
von Borries built the first model of the commercial TEM for the Siemens-Halske
Company in Berlin, Germany. The English engineer Sir Charles Oatley invented the
SEM in its present form in 1952.

intra-abdominal fat
what is it? Fat
packed deep in the abdomen, in and around your internal organs. Women with
waists over 35 inches and men with waists over 40 inches are likely to have it.
(For people of Asian descent, risk rises with measurements over 31.5 inches for
women and 37.5 for men.) A large waist is dangerous even if your body weight is
within the " healthy" range for your height. To measure your waist, wrap
a tape measure snugly around your midsection at about belly-button height.
What causes it? Too many hamburgers, too much TV, and too much
of all those other activities that keep you sitting down, like working and
driving. In other words, a diet high in calories and a life devoid of exercise.
Chronic stress plays a role, too, especially for women, since the stress
hormone cortisol directs your body to store more fat in your abdomen.
1. A high-calorie diet, lack of exercise, and chronic stress
conspire to prompt your body to store dangerous fat around your liver,
pancreas, and other internal organs.
2. Intra-abdominal fat pumps free fatty acids and inflammatory
compounds into the portal vein, the "superhighway" that delivers blood
from your lower abdomen to the liver, pancreas, and other internal organs.
3. An influx of
free fatty acids causes your liver to produce more “bad” LDL cholesterol, less “good”
HDL cholesterol, more blood sugar, and less adiponectin, a hormone that regulates
the use of blood sugar and keeps appetite in check. The result: Your risk of heart
disease and diabetes rises.
4. The inflammatory
compounds secreted by fat cells encourage the growth of plaque inside artery
walls, boost blood pressure, and make blood more likely to clot - a recipe for
a heart attack. They also make cells resistant to insulin, which in turn
contributes to diseases from Alzheimer's to cancer.

Breast Cancer – What we Know
The incidence of breast cancer in the United States began
climbing steadily in the early 1970s, and is now the highest ever seen in human
history. Nearly 50,000 American women die of the disease every year. In the
face of this tragedy, a great deal of attention has been given to genetics, but
the presence of the breast cancer susceptibility gene, called BRCA-1, only
accounts for at most 5 percent of breast cancers.
Exercise is very important to breast cancer risk. In fact,
women who exercise (walk) for four
hours per week lower their risk by 33 percent. And women who exercise more than that lower their risk even further. [29]
But diet, it turns
out, is even more important. . .
What We Know
Death rate from
breast cancer in the United States: 22.4 (per 100,000)
Death rate from
breast cancer in Japan: 6.3 (per 100,000)
Death rate from
breast cancer in China: 4.6 (per 100,000)
Primary reasons for
difference: People in China and Japan eat more fruits and vegetables and less
animal products, weigh less, drink less alcohol, and get more exercise than
people in the United States.

Fungal Diseases of Plants
Most types of plant-related diseases are caused by fungi.
The leaves of this plant have been infected by tar-spot fungus. Fungi can
infect all parts of the plant including leaves, stems, flowers, roots, and
fruit. The physical manifestations of fungal diseases of plants include
wilting, club root, root rot, wood rot, cankers, various types of mildews,
blights, lesions, and leaf spots. The effects of fungal diseases can be
devastating as evidenced by the potato blight that destroyed the Irish potato
harvest of 1845 and caused a widespread famine in Ireland. (Encarta

Geometry
Geometry is a branch of mathematics that deals with shapes
and sizes. Geometry may be thought of as the science of space. Just as
arithmetic deals with experiences that involve counting, so geometry describes
and relates experiences that involve space. Basic geometry allows us to
determine properties such as the areas and perimeters of two-dimensional shapes
and the surface areas and volumes of three-dimensional shapes. People use
formulas derived from geometry in everyday life for tasks such as figuring how much
paint they will need to cover the walls of a house or calculating the amount of
water a fish tank holds.
Geometry combines simple conceptual building blocks to
construct complex logical structures. These building blocks include undefined
terms, defined terms, and postulates. Combining these components creates chains
of reasoning that support conclusions called theorems.
Undefined terms
Some concepts central to geometry are not defined in terms
of simpler concepts. The most familiar of these undefined terms are point,
line, and plane.

What Matter Is Made Of
The best analogy for how we are coming to understand matter
is the peeling of an onion. We peel off one layer and penetrate to a deeper one,
only to discover that there is yet another to work on. The first layer was
peeled off our onion in 1805, when British chemist John Dalton published the
modern atomic theory of matter. He showed that the enormous variety of
substances that surround us is made up of only a few different chemical
elements, each of which has its own type of atom. In the early twentieth
century the second layer was peeled off when the structure of the atom was
revealed. All of the different kinds of atoms, it was argued, were made up of
only three kinds of elementary particles – protons and neutrons in the nucleus
and electrons orbiting the nucleus; this picture of the atom would become more
or less standard. For a while, its inherent simplicity seemed to be clouded
when it was found that there were not just two types of particles inside the
nucleus, but hundreds. Most of these appeared and disappeared too quickly to be
seen, but they could be produced independently in accelerators.
In the mid-1960s, yet another layer was peeled off. It was
pointed out that the myriad elementary particles are actually made up of a
small number of still more basic entities called quarks. Quarks are held
together by particles called gluons -- they're the Elmer's that keeps the three
quarks of a proton or neutron together. Scientists believe that these particles
derive from an even more basic form of matter called quark-gluon plasma, a
primordial soup that made up the universe ten millionths of a second after the
Big Bang. As things cooled down, this liquid went through "hadronization,"
hardening into protons and neutrons, which in turn coalesced first into nuclei,
then into atoms. After that, the atoms came together to form molecules, which
eventually transformed into you, this book, and the easy chair you're sitting
in. At least, that's the theory. (‘An Incomplete Education’, by Judy Jones and
William Wilson)

Human beings are virtually identical to one another at the level of genes
In our own genetic profile, believe it or not, scientific
evidence indicates that we humans share 99.4 percent of our total DNA sequences
with the chimpanzees. This doesn’t mean, of course, that humans are direct
descendants from our tree-swinging friends, but it does emphasize that the
genius of our molecular code is supported by eons of nature’s greatest
evolutionary effort. Our human code was not a random act, at least not in its
entirety, but rather is better constructed as nature’s ever-evolving quest for
a body of genetic perfection.
As members of the same human species, you and I share all
but 0.01 percent (1/100th of 1 percent) of identical genetic
sequences. So biologically, as species, you and I are virtually identical to
one another at the level of genes (99.99 percent). Looking around at the
diversity within our human race, it is obvious that 0.01 percent accounts for a
significant difference in how we look, think and behave. (‘My Stroke of Insight’, by Jill Bolte Taylor, Ph.D.)

Viruses are not considered living organisms
Because they are unable to accomplish life's processes by
themselves, viruses are not considered living organisms. They are able to
metabolize and reproduce only when they are within living cells. Thus, all
viruses are parasites, and many of them cause disease.
Much smaller than the smallest bacteria, most viruses consist
only of a strand or two of a nucleic acid – DNA or RNA - wrapped in a protein
coat. Some also have a lipid envelope outside the coat. A virus reproduces and spreads
because once its nucleic acid is inside a cell, the virus uses the cell's own
DNA to produce additional copies of itself. (‘The New York Times Guide to
Essential Knowledge’)

The Origin of Language
The use of language is
one of the key characteristics that distinguish Homo sapiens from
other primates. Because no direct evidence of language exists in the fossil record,
researchers have had a difficult time inferring its development. Fortunately,
the evolutionary history of the human brain and throat offers some insight.
The
human brain plays a vital role in the production and comprehension of language;
therefore, the emergence of language capabilities should be reflected somehow
in changes to the brain's structure. If this is true, the fossil record can help. Although brain tissue
doesn't fossilize, surviving crania can be used to make endocasts, which reveal the shape of the
brain that the cranium being cast once held. Because studies of modern human
brains have identified the areas where speech production and language
comprehension take place, researchers using endocasts can trace the development of these areas over time.
Differences
observed in the throat anatomies of modern humans and primates have also aided
researches in making inferences about the development of language capabilities.
The larynx, for example, occupies a lower position in the human throat than it
does in the throats of other primates. This arrangement makes possible the large
human pharynx, which produces the relatively wide variety of sounds used in human
speech. There is, however, a strong disadvantage to this arrangement: a greatly
increased risk of choking while eating or drinking. Therefore, language must
have been a strongly advantageous trait; otherwise, the increased incidence of
choking would have ensured its elimination through the process of natural
selection.

It takes less energy to be a healthy person than to be a sick one
How would you experience optimal efficiency of your healing system? Very
likely you would not be aware of it, because we
tend to pay little attention to our health when it is good. You would recover speedily from
illness and heal from injuries uneventfully. Ordinary stresses of everyday life
might annoy you but would not derange your digestion or blood pressure. Sleep
would be restful, sex enjoyable.
Aging of
your body would occur gradually, allowing you to moderate your activity
appropriately and live out a normal life span without undue discomfort. You would
not contract heart disease or cancer
in middle age, be crippled by arthritis in later life, or lose your mind to premature
senility.
This scenario is realistic and, I think, worth working for. Actually,
the body
wants to be healthy, because health represents
efficient operation of all of its systems. A useful analogy is the engine of a far. When all
components
are doing what they should be doing in just the right way, efficiency is maximal, and operation is quiet,
producing a "contented" purr that you rarely notice. An engine
that calls attention
to itself by sounding noisy and rough, hocking,
and expelling black smoke is not efficient. Since efficiency is the ratio
of work done to energy supplied, the sick engine is working harder to accomplish
less. In a similar way it takes less energy to be a healthy person than to be a sick one, and just as a driver may not pay
attention to the sound of a well-running engine, people may not be aware of the
condition of good health until it breaks down. A program to boost the efficiency of
the healing system will not necessarily produce
immediately noticeable changes. It is a long-term investment in the future of
the body. (Andrew Weil, M.D., ‘Spontaneous Healing’)

“Wise Women” - their contributions to health and healing
Most medical histories chronicle great discoveries by great
men, from Hippocrates, the father of medicine, to Alexander Fleming, who
discovered penicillin. Their contributions should not be underestimated, but
from ancient times down to the present day, a relatively small number of male
physicians have made the great discoveries and ministered to the kings and
princes, while an enormous number of women herbalists have taken care of
everyone else.
Women healers have gone by many names: midwives, wise women,
green women, witches, old wives, and nurses. Most physicians have never taken
women's folk healing very seriously, and scientists often dismiss folk wisdom
as "old wives' tales."
But the fact is, medically untrained women still provide
most of the world's primary care. Even in the United States, most people view
physicians as the health-care choice of last resort. The medical profession
promotes the idea that family doctors are our "primary providers,"
but studies show that before people call health professionals, about 90 percent
consult a friend or family member, and those "health advisers" are
overwhelmingly women.
Not only that, women have always been the primary consumers
of health care. Today women account for an estimated two-thirds of all
physician visits and three-quarters of all prescriptions. It's no coincidence
many herbs were used historically to calm the womb, trigger menstruation,
induce abortion, promote or dry up mothers' milk, and treat infant colic and
infectious diarrhea (still a leading cause of infant death in the Third World).
These were the daily concerns women patients brought to their women healers.

The original use of the word “chaos”
In Greek mythology, Chaos was the primal void that gave birth
to Gaea (Earth), Tartarus (Infernal Regions), Eros (Love), Erebus (Darkness),
and Nyx (Night). (The Book of Answers, by Barbara Berliner)

On the back of the US $1 bill, what do the words “Annuit Coeptis” mean?
The motto above the eye on the dollar bill means, ''He [God] Favored Our
Undertakings." The eye represents the all-seeing deity. The pyramid
symbolizes strength; it is unfinished to suggest the work ahead. (The Book of
Answers, by Barbara Berliner)

How Tuesday got its name
The Romans named the third day of the week dies Martis, for
Mars, the god of war. It is still known as mardi in French and as martes in
Spanish. The Germanic people used the name of their own war god, Tiu -- giving
us the name Tuesday.
A few Tuesdays have special importance. The Tuesday after
the first Monday in November is Election Day in the United States. People go to
the polls to choose the officials who will run the government.
In the Christian calendar, Shrove Tuesday comes right before
Lent, -- the 40-day period of prayer and fasting that leads up
to Easter. It's -- the last chance for people to eat,
drink, and make merry. In days gone by, people tried
to use up all the butter and other fats they had on this day
because they would have to give up fats during Lent. Rich,
buttery foods became a Shrove Tuesday tradition. So this day is also
known as Pancake Tuesday, and as Fat Tuesday (or Mardi Gras, in
French).
Today some cities still hold Mardi Gras parades and
festivals. The Mardi Gras celebration in New Orleans is one of the most famous.
But most Tuesdays are just ordinary days. And Tuesdays of the past were pretty dull:
Just as Monday was washday, Tuesday was ironing day. (Grolier New Book of
Knowledge Encyclopedia)

The actual shape of a raindrop
Although
a raindrop has been illustrated as being pear-shaped or tear-shaped, high-speed
photographs reveal that a large raindrop has a spherical shape with a hole not quite
through it (giving it a doughnut-like shape). Water surface tension pulls the
drop into this shape. As a drop larger than 0.08 inches (2 millimeters) in diameter
falls, it will become distorted. Air pressure flattens its bottom and its sides
bulge. If it becomes larger than 0.25 inches (6.4 millimeters) across, it will
keep spreading crosswise as it falls and will bulge more at its sides, while at
the same time, its middle will thin into a bow-tie shape. Eventually in its
path downward, it will divide into two smaller spherical drops. (The Handy

Naming hurricanes and tropical storms
Since 1950, hurricane names are officially selected from library sources
and are decided during the international meetings of the World Meteorological
Organization (WHO). The names are chosen to reflect the cultures and languages
found in the Atlantic, Caribbean, and Hawaiian regions. The National Hurricane
Center near Miami, Florida, selects the name from one of the six listings for
Region 4 (Atlantic and Caribbean area) when a tropical storm with rotary action
and wind speeds above 39 miles (62 kilometers) per hour
develops. Letters Q, U, X, Y, and Z are not included because of the scarcity of names beginning
with those letters. Once a storm has done great damage, its name is retired
from the six-year list cycle. (The Handy Science Answer Book, compiled by the
Science and Technology department of the Carnegie Library of Pittsburgh)

Is Chicago the windiest city in the US?
In 1990
Chicago ranked 21st in the list of 68 windy cities with an average wind speed
of 10.3 miles (16.6 kilometers) per hour. Cheyenne, Wyoming, with an average
wind speed of 12.9 miles ( 20.8
kilometers) per hour, ranks number one, closely followed by Great Falls,
Montana, with an average wind speed of 12.8 miles (20.6 kilometers) per hour.
The highest surface wind ever recorded was on Mount Washington, New Hampshire,
at an elevation of 6288 feet (1.9 kilometers). On April 12, 1934 its wind was 231
miles (371.7 kilometers) per hour and its average wind speed was 35 miles (56.3
kilometers) per hour. (The Handy Science Answer Book, compiled by the Science

How hot is lightning?
The temperature of the air around a bolt of lightning is
about 54,000 Fahrenheit (30,000 Celsius),
which is six times hotter than the surface of the sun, yet many times
people survive a bolt of lightning. American park ranger Roy Sullivan was hit
by lightning seven times between 1942 and 1977. In cloud-to-ground lightning,
its energy seeks the shortest route to Earth, which could be through a person's
shoulder, down the side of the body through the leg to the ground. As long as the lightning does not
pass across the heart or spinal column, the victim usually does not die. (The

The first discovery of the harmful effects of cholesterol
Some of the first evidence indicating that atherosclerosis
was not simply a consequence of growing old but was rooted in our dietary
intake of saturated fat and cholesterol came inadvertently from the Korean War.
Soldiers who had been killed were autopsied, and medical researchers were
stunned by what
they found. More than 77 percent of the American soldiers had blood vessels
that were already narrowed by atherosclerotic deposits, while the arteries-of
the equally young soldiers of the opposing forces showed no similar damage.
At the time, it was thought that the pronounced differences
in the conditions of the soldiers' arteries might be more a consequence of
genetic predisposition than of their differing diet-styles. But this idea
became quickly untenable when a large group of Korean soldiers were put on the U.S.
Army diet. They rapidly developed significant increases in their blood
cholesterol levels, an unmistakable sign of developing atherosclerosis.
Traditional nutritionists had thought highly of meat, dairy
products, and eggs ever since the early animal experiments that showed rats
grew faster on animal protein. As well, the first vitamin ever discovered,
vitamin A, had originally been isolated from butterfat, which also added to the
aura of supremacy these foods enjoyed.

Electromagnetic force
It is
this force that links atoms and molecules to form ordinary solid bodies. Thus,
if your elbow doesn't sink into the wood of your desk while you are writing, it
is because the electrons in the atoms of your desk and of your elbow push against
each other by means of electromagnetic interaction.
The
relationship between electricity and magnetism was discovered in 1820 by Christian
Oersted (Denmark) in an experiment during which he noticed that a magnetic
needle was deflected by an electric current. Andre Marie Ampere (France) later
generalized these observations, but it was James Clerk Maxwell (Great Britain)
who, in 1864, formulated the general laws of electromagnetism and showed that
light was nothing but an electromagnetic wave.
Since
the 1930s a number of physicists such as P.A.M. Dirac (Great Britain) and
Richard Feynman and Julian Schwinger (both U.S.) have developed the modem
theory of electromagnetic interaction between electrons (with the exchange of
photons). (‘Inventions and Discoveries’)

First time speed of light was measured
The
astronomer Jean Picard (France, 1620-82) of the Observatoire de Paris -- who
was the first to measure the earth's diameter precisely -- had a young Dane,
Olaus Romer, as his assistant. The latter carried out observations of the four large
satellites of Jupiter discovered by Galileo some 70 years earlier. He measured
the intervals of time between the successive eclipses of the satellites by
Jupiter and noted that these were regularly shorter or longer depending on whether
Jupiter and the earth were closer together or further apart in their respective
orbits around the sun.
Romer understood that this phenomenon was due to delays in the light from Jupiter reaching earth. He then calculated that, to explain all these observations, light traveled at a speed of 186,400 miles per second. At last, after 2,000 years of controversy, it was established that light did not travel instantaneously, but has a finite and measurable speed. (‘Inventions and Discoveries’)

Synergy
In medicine, synergy is the "cooperative" action
of two or more drugs, muscles, or organs. The term is applied especially to
drugs whose combined action is more powerful than their simple effects added
together.If used in a business application, synergy means that teamwork will produce an overall better result than if each person within the group were working toward the same goal individually. However, the concept of group cohesion needs to be considered. Group cohesion is that property that is inferred from the number and strength of mutual positive attitudes among members of the group. As the group becomes more cohesive, its functioning is affected in a number of ways. First, the interactions and communication between members increase. Common goals, interests and small size all contribute to this. In addition, group member satisfaction increases as the group provides friendship and support against outside threats.
There are negative aspects of group cohesion that have an effect on group decision-making and hence on group effectiveness. There are two issues arising. The risky shift phenomenon is the tendency of a group to make decisions that are riskier than those that the group would have recommended individually. Group Polarisation is when individuals in a group begin by taking a moderate stance on an issue regarding a common value and, after having discussed it, end up taking a more extreme stance.
A second, potential negative consequence of group cohesion is group think. Group think is a mode of thinking that people engage in when they are deeply involved in cohesive group, when the members' striving for unanimity overrides their motivation to appraise realistically the alternative courses of action.

Temperature Scales
Five different temperature scales are in use today:
(1) the Celsius scale, known also as the Centigrade scale,
(2) the Fahrenheit scale,
(3) the Kelvin scale,
(4) the Rankine scale, and
(5) the international thermodynamic temperature scale.
The Celsius scale, with a freezing point of 0° C and a
boiling point of 100° C, is widely used throughout the world, particularly for
scientific work, although it was superseded officially in 1950 by the
international temperature scale. In the Fahrenheit scale, used in
English-speaking countries for purposes other than scientific work and based on
the mercury thermometer, the freezing point of water is defined as 32° F and
the boiling point as 212° F (see Mercury). In the Kelvin scale, the most
commonly used thermodynamic temperature scale, zero is defined as the absolute
zero of temperature, that is, -273.15° C, or -459.67° F. Another scale
employing absolute zero as its lowest point is the Rankine scale, in which each
degree of temperature is equivalent to one degree on the Fahrenheit scale. The
freezing point of water on the Rankine scale is 492° R, and the boiling point
is 672° R.
In 1933 scientists of 31 nations adopted a new international
temperature scale with additional fixed temperature points, based on the Kelvin
scale and thermodynamic principles. The international scale is based on the
property of electrical resistivity, with platinum wire as the standard for
temperature between -190° and 660° C. Above 660° C, to the melting point of
gold, 1063° C, a standard thermocouple, which is a device that measures
temperature by the amount of voltage produced between two wires of different
metals, is used; beyond this point temperatures are measured by the so-called
optical pyrometer, which uses the intensity of light of a wavelength emitted by
a hot body for the purpose. (Encarta Encyclopedia)
