A Map of People Not of Land Mass

This map shows what the world would look like if a country's size were proportional to its population. It radically rearranges our sense of geographic space. Vast countries such as Russia, Canada and Australia turn into slivers of territory. Europe, and not South Asia, appears to be the red Asian subcontinent. 

Compiled by Reddit user TeaDranks, the map is an adapted version of a Population Map made in 2005 by cartographer Paul Breding and published by ODTmaps.com. TeaDranks updated its numbers. What the map emphasizes is the primacy of Asia. The continent's immensity is understood in the West but not truly appreciated. That, of course, is echoed in the Western media, where crises in Europe and conflicts in the Middle East still hold far more attention.

The lack of coverage of India's elections last year - the world's greatest exercise in democracy - was lampooned by comedians. And many Americans probably weren't even aware of a similar landmark vote in Indonesia, home to the world's largest population of Muslims, or of Saturday's upcoming presidential vote in Nigeria, which will continue its longest stretch of democracy.

Some Asian cities, as delineated on the map, are larger than most European countries. As the continent boasts some of the world's most dynamic developing economies, this map is a useful illustration for why some believe the 21st century will be the Asian Century.

The world's language total -- 7,000, nine giants: Mandarin, Spanish, English, Arabic, Hindi, Bengali, Portuguese, Russian, and Japanese

The known number of distinct languages still spoken or recently spoken in the modern world is around 7,000. That huge total may astonish many readers, because most of us could name only a few dozen languages, and the vast majority of languages are unfamiliar to us. Most languages are unwritten, spoken by few people, and spoken far from the industrial world. For example, all of Europe west of Russia has fewer than 100 native languages, but the African continent and the Indian subcontinent have over 1,000 native languages each, the African countries of Nigeria and Cameroon 527 and 286 languages respectively, and the small Pacific island nation of Vanuatu (area less than 5,000 square miles) 110 languages. The world's highest language diversity is on the island of New Guinea, with about 1,000 languages and an unknown but apparently large number of distinct language families crammed into an area only slightly larger than Texas.

Marco Polo (1254-1324)

A Venetian traveler and author, whose account of his travels and experiences in China offered Europeans a firsthand view of Asian lands and stimulated interest in Asian trade.

Marco Polo was born in Venice, one of the most prominent centers of trade in medieval Europe, into a merchant family. Venetian merchants of the day traded regularly throughout the Mediterranean region. They also maintained trading posts in port cities on the Black Sea, where they obtained silk, porcelain, and other goods that came from China over the Silk Road, an ancient trade route linking China with Rome. Little is known about Marco Polo’s early life, because his own account of his travels, published later in his life, is the primary source of biographical material about him. Polo probably received a fairly typical education for children of merchants at that time, learning how to read, write, and calculate.

Marco Polo’s account is also the primary source of information about the travels of his father and uncle, Niccolò and Maffeo Polo, who were jewel merchants. They left Venice in 1260 on a commercial venture to the Black Sea ports of Constantinople (now İstanbul, Turkey) and Soldaia (now Sudak, Ukraine). From Soldaia they continued farther east to trading cities on the Volga River in present-day Russia. In 1262 a war broke out behind them and prevented them from returning home, so they proceeded farther east to the great Central Asian trading city of Bukhara (in present-day Uzbekistan). After three years there they joined a diplomatic mission going to the court of Kublai Khan, the Mongol ruler of China. The khan received them warmly and expressed a desire to learn more about Christianity. He asked the Polo brothers to return to Europe and persuade the pope to send Christian scholars who could explain the religion to him. Niccolò and Maffeo journeyed back to Europe in 1269 to satisfy the khan’s request.

Sultan ‘Abdu’l-Aziz

He was the 32^nd Sultan of the Ottoman Empire and the 111 Caliph of the Muslim community.  He reigned between 1861 and 1876. He was the son of Sultan Mahmud II and succeeded his brother ‘Abdu’l-Majid I. He continued the westernizing reforms that had been initiated by his predecessors until 1871, after which his reign took an absolutist turn.

Like his brother ‘Abdu’l-Majid I, ‘Abdu’l-Aziz, was an ardent admirer of the material progress in western Europe. Educated in the Ottoman tradition, however, he could not always accept the adoption of Western institutions and customs. ‘Abdu’l-Aziz was a member of the Mawlawiyah (Mevlevi) order of dervishes (Muslim mystics).

Between 1861 and 1871, reforms were continued under the leadership of Abdu’l-Aziz's able chief ministers, Fuad Pasha and ‘Ali Pasha. New administrative districts (vilayets) were set up in 1864; on French advice a council of state was established in 1868; public education was organized on the French model and a new university founded; and the first Ottoman civil code was promulgated. ‘Abdu’l-Aziz cultivated good relations with France and Great Britain and was the first Ottoman sultan to visit western Europe.

Dogs – first animal to be domesticated by humans

The dog is one of the two most ubiquitous and popular domestic animals in the world (the cat is the other). For more than 12,000 years it has lived with humans as a hunting companion, protector, object of scorn or adoration, and friend. The dog has evolved from similar (that is, undifferentiated) fur-bearing animals into more than 400 distinct breeds. Human beings have played a major role in creating dogs that fulfill distinct societal needs. Through the most rudimentary form of genetic engineering, dogs were bred to accentuate instincts that were evident from their earliest encounters with humans. Although details about the evolution of dogs are uncertain, the first dogs were hunters with keen senses of sight and smell. Humans developed these instincts and created new breeds as need or desire arose.

Dogs are regarded differently in different parts of the world. Western civilization has given the relationship between human and dog great importance, but, in some of the developing nations and in many areas of Asia, dogs are not held in the same esteem. In some areas of the world, dogs are used as guards or beasts of burden or even for food, whereas, in the United States and Europe, dogs are protected and admired. In ancient Egypt during the days of the pharoahs, dogs were considered to be sacred.

Antibody

An antibody also known as immunoglobulin is a Y-shape protective protein produced by the immune system in response to the presence of a foreign substance, called an antigen. Antibodies recognize and latch onto antigens in order to remove them from the body. A wide range of substances are regarded by the body as antigens, including disease-causing organisms and toxic materials such as insect venom.

When an alien substance enters the body, the immune system is able to recognize it as foreign because molecules on the surface of the antigen differ from those found in the body. To eliminate the invader, the immune system calls on a number of mechanisms, including one of the most important — antibody production. Antibodies are produced by specialized white blood cells called B lymphocytes or B cells. When an antigen binds to the B-cell surface, it stimulates the B cell to divide and mature into a group of identical cells called a clone. The mature B cells, called plasma cells, secrete millions of antibodies into the bloodstream and lymphatic system.

Persia - One of the world’s first civilizations

Persia (which changed its name to Iran in 1935) was one of the world's first civilizations; it has evidence of Neolithic Aryan (peoples who spoke Indo-European languages) settlements from nearly ten thousand years ago. Persians are a non-Arab people who migrated from central Asia. According to National Geographic, "If you draw lines from the Mediterranean to Beijing or Beijing to Cairo or Paris to Delhi, they all pass through Iran, which straddles a region where East meets West. Over 26 centuries, a blending of the hemispheres has been going on here-trade, cultural interchange, friction -- with Iran smack in the middle."

The Elamites established the first known Persian dynasty in the third millennium BC. Another Aryan people, the Medes (the ancestors of the Kurds of today), created a unified empire in the northwestern part of that region around 625 BC. Cyrus the Great, who issued what some consider the world's first declaration of human rights, overthrew the Medes and established the Achaemenid Empire, expanding Persian control and influence from Egypt to India -- making it one of the largest empires in history. His descendants, Darius and his son Xerxes, invaded Greece but were defeated and expelled from Europe in 479 BC.

In the next century, Alexander the Great conquered Persia and ended the Achaemenid dynasty. After about a hundred years of Alexander's Seleucid Empire, the Parthian and Sassanid dynasties reestablished Persian rule until the Arab invasion in the seventh century AD. The Persians, the Kurds, the Turks, and others then converted to Islam.

Arterial stiffness

Arterial stiffness occurs as a consequence of age and arteriosclerosis. Age related stiffness occurs when the elastic fibres within the arterial wall (elastin) begin to fray due to mechanical stress. The two leading causes of death in the developed world, myocardial infarction and stroke, are both a direct consequence of atherosclerosis. Increased arterial stiffness is associated with an increased risk of cardiovascular events.

When the heart contracts it generates a pulse or energy wave that travels through the circulation. The speed of travel of this pulse wave (pulse wave velocity or PWV) is related to the stiffness of the arteries. 

(PWV) is a measure of arterial stiffness. It is easy to measure invasively and non-invasively in humans, is highly reproducible, has a strong correlation with cardiovascular events and all-cause mortality, and was recognized by the European Society of Hypertension as integral to the diagnosis and treatment of hypertension.

History of Biology

The systematic approach to biology started with the Greek philosophers about 2,500 years ago. Aristotle (384-322 B.C.) is considered the "father of biology" for his classification of animals and for performing the first known biology experiments, dissecting plants and animals and studying the development of the chick in its egg. His student Theophrastus (ca. 372-286 B.C.) laid the foundation of botany, describing and classifying more than 500 plants and also describing the ways plants can germinate and grow. In Roman times, Lucretius (99-55 B.C.) proposed one of the earliest theories of evolution. But other than medical knowledge, biology made little progress until after the Middle Ages.

In the 15th and 16th centuries Europeans explored the Americas and some of the Pacific islands, and regular contact between Europe and southern Africa and eastern Asia was instituted. As a result European scholars were exposed to a great variety of plants and animals that were new to them. They responded with books describing and classifying both newfound and familiar plants and animals, starting as early as 1530. A few years later the first botanical gardens began to be established. When the scientific revolution of the 17th century began, scientists undertook more detailed experiments in biology. For example, Jan van Helmont (1579-1694) carefully measured the weight of soil in a tub as a willow grew there, establishing that the increase in mass of the willow was much greater than any diminution of mass of the soil.

The universe’s invisible web

Something out there holds swarms of galaxies together and keeps their stars from flying apart, but scientists still haven’t learned what this invisible substance is. Known as dark matter, it gathers to form a colossal cosmic scaffolding. Astronomers believe that galaxies formed at the densest points in this weblike structure, and the dark matter continues to hold them in place with its gravity. Its bulky presence can be detected by tracking stars on the outskirts of galaxies, which move at speeds that would be impossible if only visible matter – a galaxy’s other stars and gas – were pulling them. Astronomers have also mapped this unseen substance with the help of an effect predicted by Einstein’s general relativity; Dark matter’s gravity wrinkles space-time, bending light rays as they pass. Such measurements indicate that dark matter could make up 90 percent of the universe’s total mass. These days, cosmologists are searching for the identity of dark matter, trying to detect the elusive substance responsible for arranging everything we see in the sky.

Healthy foods, healthy arteries: is there a connection?

What you eat can help keep your heart and arteries healthy — or lead to excessive weight, high blood   pressure, and high blood cholesterol — three key factors that increase the risk of developing cardiovascular disease, according to the National Heart, Lung, and Blood Institute. Based on the best available scientific evidence, the American Heart Association (AHA) recommends a diet that includes a variety of fruits, vegetables, and grains, while limiting consumption of saturated fat and sodium.  

Fruits and vegetables have lots of antioxidants such as vitamin C and vitamin A that neutralize free radicals and may prevent oxidation in the arteries, dietary experts say. Fruits and vegetables also contain plenty of soluble fiber, a substance that has been shown to reduce blood cholesterol levels, which is healthy for the endothelium.  

Breads, cereals, and other grain foods, which provide complex carbohydrates, vitamins, minerals, and fiber, are associated with a decreased risk of cardiovascular disease, according to the AHA Dietary Guidelines. However, some studies suggest eating less sugar, breads, and other simple and complex carbohydrates can lower blood insulin levels and decrease body fat and weight — three factors that are linked to an increased risk of heart disease and stroke. In recent years, a number of dietary recommendations based on these findings have become popular and are currently catching   the public’s awareness. While contentious, these are important issues and long-term studies are required to determine the risks and benefits of such diets, Dr. Lakatta says. 

Viruses on other life-bearing planets

It has been proposed that viruses are likely to be encountered on other life-bearing planets. Efforts to discover current or past life on Mars is an active area of research. On 24 January 2014, NASA reported that current studies on the planet Mars by the Curiosity and Opportunity rovers will now be searching for evidence of ancient life, including a biosphere based on autotrophic, chemotrophic and/or chemolithoautotrophic microorganisms, as well as ancient water, including fluvio-lacustrine environments (plains related to ancient rivers or lakes) that may have been habitable. The search for evidence of habitability, taphonomy (related to fossils), and organic carbon on the planet Mars is now a primary NASA objective.

Ancient Egypt - political history

Ancient Egypt was one of the world's great early civilizations, a nation and culture that dominated northern Africa for nearly 3,000 years and saw hundreds of kings rule over some 30 dynasties. Factors like climate and geography, together with innovative leadership and bureaucratic organization, made possible a legacy that continues to fascinate scholars and amateurs alike: the pyramids, with their staggering scale and mathematical ingenuity; mummies and tombs that provide modern researchers with an enormous body of material to examine; and innumerable carvings of pictures and writing, made decipherable by the Rosetta Stone. The unusually high status of women, the worship of gods of sun and nature, and a fixation on the afterlife are some of the themes that make ancient Egypt alluring to modem students.

As the Ganges was to India and the Yangtze to China, the Nile River was the mother of Egyptian civilization, spurring the rise of agriculture, trade, and one of the most successful societies in the ancient world. Flowing northward out of Burundi into Lake Victoria then through Uganda and Sudan on its way to the Mediterranean Sea, the Nile is the longest river in the world, traversing more than 4,000 miles of the African continent.

Keeping Your Arteries Healthy

The well-being of your arteries depends on a healthy endothelium, the inner lining of your blood vessels. “Endothelial cells are the prima donnas within the blood vessels. They control almost every activity that occurs in the vessels, and they’re fundamentally altered with age,” Dr. Lakatta says. “People who maintain a healthy endothelium as they get older and those who make an effort to do things that promote the repair of injured endothelium can reduce the risk of heart attacks and strokes caused by atherosclerosis or hypertension.”

Although scientists still have much to learn about the endothelium and what can be done to keep it healthy, a number of studies suggest that certain modifiable risk factors can have an important impact on the cardiovascular system. For instance, regular moderate exercise, such as running, walking, or swimming can reduce body fat, increase lean muscle mass, decrease blood pressure, increase HDL cholesterol (the “good” cholesterol) levels, and lessen the extent of arterial stiffening. All of these exercise-induced changes can have a positive influence on endothelial cells.

Astrobiology

Astrobiology is the study of the origin, evolution, distribution, and future of life in the universe: extraterrestrial life and life on Earth. This interdisciplinary field encompasses the search for habitable environments in our Solar System and habitable planets outside our Solar System, the search for evidence of prebiotic chemistry, laboratory and field research into the origins and early evolution of life on Earth, and studies of the potential for life to adapt to challenges on Earth and in outer space. Astrobiology addresses the question of whether life exists beyond Earth, and how humans can detect it if it does. (The term exobiology is similar but more specific — it covers the search for life beyond Earth, and the effects of extraterrestrial environments on living things.)

Astrobiology makes use of physics, chemistry, astronomy, biology, molecular biology, ecology, planetary science, geography, and geology to investigate the possibility of life on other worlds and help recognize biospheres that might be different from the biosphere on Earth. Astrobiology concerns itself with interpretation of existing scientific data; given more detailed and reliable data from other parts of the universe, the roots of astrobiology itself — physics, chemistry and biology — may have their theoretical bases challenged. Although speculation is entertained to give context, astrobiology concerns itself primarily with hypotheses that fit firmly into existing scientific theories.

Consciousness

Consciousness is defined in the dictionary as: 1. the state of being conscious; awareness of one's own existence, sensations, thoughts, surroundings, etc.  2. the thoughts and feelings, collectively, of an individual or of an aggregate of people: the moral consciousness of a nation.3. full activity of the mind and senses, as in waking life: to regain consciousness after fainting. 4. awareness of something for what it is; internal knowledge: consciousness of wrongdoing. 5. concern, interest, or acute awareness: class consciousness. 6. the mental activity of which a person is aware as contrasted with unconscious mental processes. 7. Philosophy. the mind or the mental faculties as characterized by thought, feelings, and volition. Idioms: raise one's consciousness: to increase one's awareness and understanding of one's own needs, behavior, attitudes, etc., especially as a member of a particular social or political group.

Psychologists define consciousness as the quality or state of awareness, or, of being aware of an external object or something within oneself. The English philosopher John Locke defined it as “the perception of what passes in a man's own mind.” It is also defined as: sentience, awareness, subjectivity, the ability to experience or to feel, wakefulness, having a sense of selfhood, and the executive control system of the mind. Despite the difficulty in definition, many philosophers believe that there is a broadly shared underlying intuition about what consciousness is.  As Max Velmans and Susan Schneider wrote in The Blackwell Companion to Consciousness: "Anything that we are aware of at a given moment forms part of our consciousness, making conscious experience at once the most familiar and most mysterious aspect of our lives."

Momentum

The boulder, unfortunately has more
momentum than the runner

Momentum is the mass of an object multiplied by its velocity. The momentum of an object depends on its mass and velocity. This means that an object's momentum changes as it accelerates. Momentum can be transferred between objects. When a moving ball collides with a stationary one, for example, the first ball transfers some of its momentum to the second ball. The total momentum of the two balls is the same as the first ball's momentum before the collision. This is called the principle of conservation of momentum.

Arteries, veins, and capillaries in human body

Three types of blood vessels form a complex network of tubes throughout the body. Arteries carry blood away from the heart, and veins carry it toward the heart. Capillaries are the tiny links between the arteries and the veins where oxygen and nutrients diffuse to body tissues. The inner layer of blood vessels is lined with endothelial cells that create a smooth passage for the transit of blood. This inner layer is surrounded by connective tissue and smooth muscle that enable the blood vessel to expand or contract. Blood vessels expand during exercise to meet the increased demand for blood and to cool the body. Blood vessels contract after an injury to reduce bleeding and also to conserve body heat.

Arteries have thicker walls than veins to withstand the pressure of blood being pumped from the heart. Blood in the veins is at a lower pressure, so veins have one-way valves to prevent blood from flowing backwards away from the heart. Capillaries, the smallest of blood vessels, are only visible by microscope—ten capillaries lying side by side are barely as thick as a human hair. If all the arteries, veins, and capillaries in the human body were placed end to end, the total length would equal more than 100,000 km (more than 60,000 miles—they could stretch around the earth nearly two and a half times.

The arteries, veins, and capillaries are divided into two systems of circulation: systemic and pulmonary. The systemic circulation carries oxygenated blood from the heart to all the tissues in the body except the lungs and returns deoxygenated blood carrying waste products, such as carbon dioxide, back to the heart. The pulmonary circulation carries this spent blood from the heart to the lungs. In the lungs, the blood releases its carbon dioxide and absorbs oxygen. The oxygenated blood then returns to the heart before transferring to the systemic circulation.

There could be as many as 40 billion Earth-sized planets orbiting in the habitable zones of sun-like stars and red dwarf stars within the Milky Way Galaxy

Earth is the only place in the universe known to harbor life. However, recent advances in planetary science have changed fundamental assumptions about the possibility of life in the universe, raising the estimates of habitable zones around other stars, along with the discovery of hundreds of extrasolar planets and new insights into the extreme habitats here on Earth, suggesting that there may be many more habitable places in the universe than considered possible until very recently. On 4 November 2013, astronomers reported, based on Kepler space mission data, that there could be as many as 40 billion Earth-sized planets orbiting in the habitable zones of sun-like stars and red dwarf stars within the Milky Way Galaxy -- 11 billion of these estimated planets may be orbiting sun-like stars. The nearest such planet may be 12 light-years away, according to the scientists.

English ranks third among the world's most spoken languages

As of 2010, Mandarin was the mother language of 14.4% of the world’s population, Spanish 6.15%, and English 5.43%.

Although English ranks only third among the world's most spoken languages, it is on its way to becoming the first truly global language - used throughout the world as the language of commerce, diplomacy, and science. English is the mother tongue for some 450 million people, and a further 1.5 billion people use it as a second language to some degree. Beginning in the 17th century, the language spread throughout the British Empire to the Americas, Africa, India, and Oceana. Today 70 countries designate English as an official language (although it does not have that status in the United States), and it is an official language of the United Nations, the European Union, Nafta, NATO, and the Organization of American States.

Kilauea – the world’s most active volcanic crater

Kilauea is located on central Hawaii Island, Hawaii. It is situated on the southeastern slope of the great volcanic mountain Mauna Loa, at an elevation of 1,247 m (4,090 ft) above sea level, which is more than 3000 m (almost 10,000 ft) below the summit of the mountain. The crater, which forms a great cavity in the side of the mountain, has an area of about 10 sq km (about 4 sq mi); the walls of the crater are from 60 to 210 m (about 200 to 700 ft) high. Except for occasional lava flows across the floor of the crater, volcanic activity in recent times has been restricted to an inner crater called Halemaumau, which measures more than 900 m (about 3000 ft) across and has a depth of about 400 m (about 1300 ft).

Cardiovascular System – its functions and components

Circulatory system, or cardiovascular system, in humans, includes the combined functions of the heart, blood, and blood vessels. It transports oxygen and nutrients to organs and tissues throughout the body and carry away waste products. Among its vital functions, the circulatory system increases the flow of blood to meet increased energy demands during exercise and regulates body temperature. In addition, when foreign substances or organisms invade the body, the circulatory system swiftly conveys disease-fighting elements of the immune system, such as white blood cells and antibodies, to regions under attack. Also, in the case of injury or bleeding, the circulatory system sends clotting cells and proteins to the affected site, which quickly stop bleeding and promote healing.

The heart, blood, and blood vessels are the three structural elements that make up the circulatory system. The heart is the engine of the circulatory system. It is divided into four chambers: the right atrium, the right ventricle, the left atrium, and the left ventricle. The walls of these chambers are made of a special muscle called myocardium, which contracts continuously and rhythmically to pump blood. The pumping action of the heart occurs in two stages for each heart beat: diastole, when the heart is at rest; and systole, when the heart contracts to pump deoxygenated blood toward the lungs and oxygenated blood to the body. During each heartbeat, typically about 60 to 90 ml (about 2 to 3 oz) of blood are pumped out of the heart. If the heart stops pumping, death usually occurs within four to five minutes.

Blood consists of three types of cells: oxygen-bearing red blood cells, disease-fighting white blood cells, and blood-clotting platelets, all of which are carried through blood vessels in a liquid called plasma. Plasma is yellowish and consists of water, salts, proteins, vitamins, minerals, hormones, dissolved gases, and fats.

Mental Energy - Feel the Flow of Enthusiasm

Call it drive, vigor, enthusiasm, or get-up-and-go. Call it zest, gusto, razzmatazz, or just plain oomph. It's what gives you ambition, puts a sparkle in your eye, and fills your day with spirit and glow. It's what makes you jump out of bed in the morning, fill your lungs with air, and charge out the front door ready to take on the entire world.

We're talking about the greatest form of energy on earth. It doesn't come from oil, coal, or natural gas. It comes from your mind.

When the energy is flowing, really flowing, nothing, but nothing, can stop you. You feel powerful, brilliant, and tremendously alive. You feel like King Kong with a Ph.D. But, when the energy stops flowing-ugh. You feel like Dr. Kong after he fell from the Empire State Building.

If you're like most people, your energy flow can get a little erratic from time to time, and you'd like to do something about it. You'd like to boost the wattage and assure yourself of a steady, never-ending supply of power.  Well? Don't just lie there like a big ape sprawled out on a Manhattan sidewalk!

The Eightfold Buddhist Path -- freeing oneself from suffering rooted in ignorance

Buddha’s first teaching to his disciples is reported to have been the “First Turning of the Wheel of Dharma.” The Sanskrit word dharma has many shades of meaning. In its original Vedic context, it meant "duty" in the sense of social obligation, such as the obligation one feels as a member of a particular caste. In a Buddhist context, however, the meaning of dharma is closer to "truth" or "reality" (or even law," as in law of nature).

The Buddha's first teaching asserted four "truths about the nature of reality. The first was that ordinary life is characterized by suffering -- physical suffering, emotional suffering, and a sort of angst inherent in day-to-day existence. The second truth was that the cause of this suffering is the desire that follows from all beings' ignorance of the true nature of reality. The third truth was that it is possible to attain a state of being in which suffering is extinguished. The fourth truth concerned the Eightfold Path leading to that state. 

Alternative technologies concerning energy

What makes a technology conventional is its widespread use, and what makes it widespread is its low cost and convenience. Therefore, almost by definition, alternative technologies cost more than conventional ones, at least in terms of the price paid by the consumer. For example, among alternative technologies, wind power has come the closest to competing with conventional fossil fuels, yet it still costs about 50 percent more than coal-generated electricity. If, however, one takes into account the hidden costs of conventional energy and the noneconomic benefits of alternative technologies, then the equation changes.

Growing awareness of the environmental costs of conventional energy has led to increased demand for cleaner energy. Global warming, in particular, has altered the way many people think about the energy they consume - which, in turn, has begun to reshape the economic relationship between energy producers and consumers. As more and more consumers sign up for green energy programs and buy hybrid cars (both of which carry additional costs), energy companies are reconsidering whether the conventional wisdom of cheap, convenient, and plentiful above all still applies. Skeptics argue that the demand for cheap, large-scale energy resources will continue to trump the relatively new consumer preference for clean, renewable alternatives. On the other hand, if the era of cheap petroleum-based energy is indeed ending -- as shrinking petroleum reserves and rising gasoline prices indicate -- then one may not even have to factor in the hidden costs and benefits for today's alternative technologies to become tomorrow's conventional resources.

Slide Rule

A mechanical device formerly used by engineers and scientists for rapid and approximate multiplication, division, extraction of roots, raising to powers, and other simple computations. The slide rule has been almost totally superseded by the small hand-held electronic calculator. The principle of the slide rule is the translation of all computations to equivalent additions or subtractions that can be carried out on a set of scales sliding over each other. Thus, two uniformly graduated marked scales can be used for addition or subtraction, multiplication, division, powers, and logarithms. Other scales, such as for sine, cosine, and tangent, and logarithm and for calculations involving p (pi) are also found on the usual rectilinear slide rule. A glass runner or cursor with a finely engraved vertical line is provided for easier alignment of the scales.

The computational accuracy possible depends on the size of the slide rule and on the care with which the scales are printed. The commonly used 10-in. slide rule permits multiplications and divisions to be made with an accuracy of about 1/10th percent, which suffices for many engineering calculations. Both the rectilinear and the less commonly used circular slide rule were invented by the English mathematician William Oughtred shortly after the discovery of logarithms. Various special slide rules have been devised for the solution of widely applicable engineering formulas, or for business calculations, such as the determination of interest, compound interest accumulation, and depreciation.

Renewable Energy – wind and solar

The first wind turbines actually predate the electric power grid, with two near-simultaneous developments in the late 19th century. The Scottish engineer James Blyth constructed a 33- foot electricity-generating wind turbine in 1887, and the following year the American engineer Charles Brush built the first automatic wind turbine, wiring the first electrically powered building in Ohio. Likewise, throughout the 1800s, scientists were experimenting in the various technologies that make photovoltaic solar panels possible; the first solar powered steam engine was built in 1861.

Since then, the use of wind and solar power has grown steadily, with a surge in recent years. Wind power, while, still providing a small total percentage of U.S. power, is growing much more rapidly than solar power. From 1990 to 2008, U.S. production of wind power grew from 300 trillion Btu annually to 510 trillion; solar has increased modestly from 60 trillion BN to 90 trillion. Shipments of solar photovoltaic cells and modules continues to expand, however. From 2000 to 2008, U.S. manufacturers increased shipments of photovoltaic components from 20,000 modules in 2000 to 524,000 modules in 2008. Production of hydroelectric power, the nation's largest renewable energy source, has remained more or less steady since 1990, declining somewhat from 3.05 quadrillion Btu to 2.45 quadrillion Btu in 2008.

Environmentalism in the United States

The first federal environmental act was the establishment of Yellowstone National Park in March 1872 in the territories of Montana and Wyoming. Instead of promoting the land for development, Congress and President Ulysses S. Grant declared that it should be preserved "as a public park or pleasuring ground for the benefit and enjoyment of the people." As the first such preserve in the world, Yellowstone inaugurated an international national park movement that currently includes some 1,200 parks or preserves in 100 countries, including 391 in the United States.

The Scottish naturalist John Muir became an early advocate for preservation after his travels and scientific work convinced him that some natural areas need protection from human exploitation. Muir founded the Sierra Club in 1892 to that end and urged President Theodore Roosevelt to join the cause. Roosevelt, himself known as an ardent outdoorsman, eventually dedicated more than 150 million acres to national parks and forests, and founded the US. Forest Service, which manages forests for water and timber resources while protecting them for wildlife and recreation. The first chief of the Forest Service, Gifford Pinchot, promoted a "wise use" strategy of wilderness management that proposed, in contrast to Muir, that nature could be safely commercialized.

The adverse effect of environmental changes on biodiversity

While pollution and global warming have obvious effects on human health, ecologists also define environmental health according to biodiversity. Biodiversity measures the variety of living things and their interactions on three levels: genetics, species, and ecosystem diversity. The number of known species - characterized by scientific analysis and description - is more than 1.7 million, including nearly 1 million species of insects, about 14,000 species of amphibians and reptiles, and 5,400 mammalian species. However, there are many other species living on Earth, including trillions of microscopic organisms like bacteria. These species interact to form sustainable check-and balance networks like the food chain.

Human population growth, deforestation, pollution, and global warming have caused a rapid loss of biodiversity. Today's extinction rate is estimated to be 1,000 to 10,000 times higher than the natural rate, and some scientists believe we are in the midst of a mass extinction. For example, the International Union for Conservation of Nature reported in 2008 that 30 percent of amphibian species are critically endangered or vulnerable. This number increased 2,588 percent between 1996 (18 species) and 2010 (484 species). (Adapted from ‘The New York Times ‘Smarter by Sunday – 52 Weekends of Essential Knowledge for the Curious Mind’)

The world's first designated wilderness

In 1924, due to Aldo Leopold's (an American environmentalist) efforts as a Forest Service employee, the Gila National Forest in New Mexico became the world's first designated wilderness. This designation allows travel only by foot or horseback and bans any commercial activity except grazing in order to protect the usefulness of the wilderness for cleaning air and reducing climate change, as well as providing clean water, wildlife habitat, and natural recreational experiences.

Air & Liquid Air

Air is the mixture of gases that surrounds the Earth. Air contains mainly the gases nitrogen and oxygen, with small amounts of argon and other noble gases and carbon dioxide. The proportions of these gases in air are the same anywhere around the world. Air also contains water vapor, dust, and polluting gases, which vary in amount from place to place. When air is cooled to -328°F (-200°C), most of the gases condense, forming a blue liquid called liquid air. (Dictionary of Science, by Neil Ardley)

America’s Independence Day

Independence Day, commonly known as the Fourth of July, is a federal holiday in the United States commemorating the adoption of the Declaration of Independence on July 4, 1776, declaring independence from the Kingdom of Great Britain (now officially known as the United Kingdom). Independence Day is commonly associated with fireworks, parades, barbecues, carnivals, fairs, picnics, concerts, baseball games, family reunions, and political speeches and ceremonies, in addition to various other public and private events celebrating the history, government, and traditions of the United States. Independence Day is the National Day of the United States.

During the American Revolution, the legal separation of the Thirteen Colonies from Great Britain occurred on July 2, 1776, when the Second Continental Congress voted to approve a resolution of independence that had been proposed in June by Richard Henry Leeof Virginia declaring the United States independent from Great Britain. After voting for independence, Congress turned its attention to the Declaration of Independence, a statement explaining this decision, which had been prepared by a Committee of Five, with Thomas Jefferson as its principal author. Congress debated and revised the wording of the Declaration, finally approving it on July 4. A day earlier, John Adams had written to his wife Abigail:

The second day of July, 1776, will be the most memorable epoch in the history of America. I am apt to believe that it will be celebrated by succeeding generations as the great anniversary festival. It ought to be commemorated as the day of deliverance, by solemn acts of devotion to God Almighty. It ought to be solemnized with pomp and parade, with shows, games, sports, guns, bells, bonfires, and illuminations, from one end of this continent to the other, from this time forward forever more.

Ben-Gurion -- Israel's "founding father" and first Prime Minister

Born David Gruen in Poland, Ben-Gurion became committed to Zionism, the movement to settle and unite Jews in Palestine, under the influence of his father and grandfather. He studied in Warsaw, where he joined Po’alei Zion (Workers of Zion), a socialist workers party. Ben-Gurion saw Zionism as a practical idea to be carried out by Jewish immigration to Palestine and building the land through collective labor. In 1906 he moved to Jaffa, Palestine (now part of Tel Aviv-Yafo, Israel), and worked as a farmer. There he was elected to the central committee of Po’alei Zion and began organizing workers into unions. In 1910 he moved to Jerusalem and joined the editorial staff of a new Hebrew-language newspaper, Ahdut (Unity), publishing articles under the name Ben-Gurion (Hebrew for "son of the young lion"). He enrolled at the University of Constantinople in present-day Turkey in 1912 and earned a law degree in 1914. He then returned to Palestine and resumed his work as a union organizer, but in 1915 he traveled to the United States after he and thousands of other Zionists were exiled by the Ottoman Empire authorities who controlled Palestine.

The Great Wall of China

Great Wall (China), popular name for a semi-legendary wall built to protect China’s northern border in the 3rd century BC, and for impressive stone and earthen fortifications built along a different northern border in the 15th and 16th centuries AD, long after the ancient structure had disappeared. Ruins of the later wall are found today along former border areas from Bo Hai (a gulf of the Yellow Sea) in the east to Gansu Province in the west. The Great Wall is visited often near Beijing, at a site called Ju-yong-guan, and at its eastern and western extremes.

Perhaps China's best known monument—even national symbol—the Great Wall is not what most people imagine it to be. The existing wall is not several thousand years old, nor is it, as is widely asserted, visible from outer space (astronauts confirm this). Indeed, the Great Wall is not even a single, continuous structure. Rather, it consists of a network of walls and towers that leaves the frontier open in places.

Colonial America: 1492-1763

European nations came to the Americas to increase their wealth and broaden their influence over world affairs. The Spanish were among the first Europeans to explore the New World and the first to settle in what is now the United States.

By 1650, however, England had established a dominant presence on the Atlantic coast. The first colony was founded at Jamestown, Virginia, in 1607. Many of the people who settled in the New World came to escape religious persecution. The Pilgrims, founders of Plymouth, Massachusetts, arrived in 1620. In both Virginia and Massachusetts, the colonists flourished with some assistance from Native Americans. New World grains such as corn kept the colonists from starving while, in Virginia, tobacco provided a valuable cash crop. By the early 1700s enslaved Africans made up a growing percentage of the colonial population. By 1770, more than 2 million people lived and worked in Great Britain's 13 North American colonies ( http://www.americaslibrary.gov/)

September 30, 1882: The World's First Hydroelectric Power Plant Began Operation

 When you look at rushing waterfalls and rivers, you may not immediately think of electricity. But hydroelectric (water-powered) power plants are responsible for lighting many of our homes and neighborhoods. On September 30, 1882, the world's first hydroelectric power plant began operation on the Fox River in Appleton, Wisconsin. The plant, later named the Appleton Edison Light Company, was initiated by Appleton paper manufacturer H.J. Rogers, who had been inspired by Thomas Edison's plans for an electricity-producing station in New York. 

Unlike Edison's New York plant which used steam power to drive its generators, the Appleton plant used the natural energy of the Fox River. When the plant opened, it produced enough electricity to light Rogers's home, the plant itself, and a nearby building. Hydroelectric power plants of today generate a lot more electricity. By the early 20th century, these plants produced a significant portion of the country's electric energy. The cheap electricity provided by the plants spurred industrial growth in many regions of the country. To get even more power out of the flowing water, the government started building dams. 

In 1933, the U.S. government established the Tennessee Valley Authority (TVA), which introduced hydroelectric power plants to the South's troubled Tennessee River Valley. The TVA built dams, managed flood control and soil conservation programs, and more. It greatly boosted the region's economy. And this development happened in other places as well. Soon, people across the country were enjoying electricity in homes, schools, and offices, reading by electric lamp instead of candlelight or kerosene. New electricity-powered technologies entered American homes, including electric refrigerators and stoves, radios, televisions, and can openers. Today, people take electricity for granted, not able to imagine life without it. (http://www.americaslibrary.gov/)
