MARIE CURIE BIOGRAPHY

Marie Sklodowska Curie was a woman scientist who was born in Warsaw, Poland on November 7, 1867. He was born in a family of teachers. Her father is a physics teacher. Meanwhile, her mother was a school principal. Marie is the youngest of five children.
She is very intelligent and has a strong memory. Thus, at the age of 15 years, she graduated from High School with highest honors. However, he could not continue their education to university because in Poland at that time she studied at the University is prohibited. In addition, he also did not have enough money because his family is poor. Therefore, at the age of 17 years he became a tutor to earn money.
Then, after collecting enough money she moved to Paris and enrolled at the Sorbonne. There, his name was eventually changed to Marie and she met in 1894. A year later they were married and since then his name to Marie Sklodowska Curie.
Two years later, Marie's interest in the study of light was discovered by Henry Becquerel in 1896. Rays are similar to X-rays on uranium. After studying the ray finally in 1898 he discovered thorium, polonium, radium, and coined the term radioactivity. Then, in 1903 he along with Henry Becquerel and Pierre Curie received the Nobel chemistry prize for discovering polonium, radium, and isolating radium which later developed into the manufacture of nuclear materials.
Because of this discovery Marie became so famous in the world. However, because of his discovery he was also attacked by blood cancer. We investigate and separate the radium was too much exposed to radioactive rays. As a result, he suffered from blood cancer and died on July 4, 1934 in Savoy, France at the age of 67 years.
Even so, she still remembered as the first woman in the world to be a professor at the Sorbonne, physicists, chemists and scientists as well as the woman who was so instrumental in finding the manufacture of nuclear materials. In addition, he also was the first person in the world that managed to get the Nobel prize twice. The first Nobel Prize for Physics and the second for Chemistry.
A year after the death of one of Marie's daughter named Irene also received the Nobel chemistry prize with her husband, Frederic Joliot, because it managed to make a new element that is radioactive. Meanwhile, another daughter named Eve became famous for being the author of biographies of Marie.

ALBERT EINSTEIN'S BIOGRAPHY

Albert Einstein (14 March 1879-18 April 1955) is a theoretical physicist widely regarded as the greatest scientist in the 20th century. He put forward the theory of relativity and also greatly contributed to the development of quantum mechanics, statistical mechanics, and cosmology. He was awarded the Nobel Prize in Physics in 1921 for his explanation of the photoelectric effect and "for his services to Theoretical Physics". Having formulated the theory of general relativity, Einstein became famous throughout the world, an unusual achievement for a scientist.
In his old age, fame beyond all scientists in history, and in popular culture, says Einstein is considered synonymous with intelligence or even genius. His face is one of the most recognized worldwide. In 1999, Einstein called "The Century" by Time magazine. Popularity also makes the name "Einstein" is widely used in advertisements and other merchandise, and finally "Albert Einstein" is registered as a trademark. To appreciate them, a unit in the photochemistry named Einstein, a chemical element named after einsteinium, and a named asteroid 2001 Einstein.

BICYCLE HISTORY

Bicycle ancestors came from France in1790 (about 18th century), namely, two-wheeled transportation called velocipede known in that country.The construction still very simple, because not using the iron, the material is still wood, and not use the wheel.
Baron von Drais Karls Sauerbronn a student of mathematics and mechanics in Heidelberg, Germany managed to make a important breakthrough .By Von Drais be modified to have a steering mechanism on the front wheels. By taking the energy of motion of both legs, Von Drais able to glide faster time around the garden. He himself calls this vehicle with the name, Draisienne. The story itself was published in local newspapers of Germany in 1817.
Modern bicycle was initiated in 1839, by a citizen named Kirkpatrick MacMillan of Scotland. While perfecting bicycle do by Ernest Michaux, the French in 1855, by making crank weights. Perfection of the modern bicycle is further reinforced again by a French citizen who was also named Pierre Lalle ment in 1865, where he strengthened the wheel by using a ring of steel around it (a rim or wheel). Lellement also introducing a bike with the front wheel bigger than the rear wheels.
But no less important discoveries made John Boyd Dunlop in 1888. Dunlop motorcycle tires managed to find technology that can be filled with air (pneumatic tire). From here, the beginning of the rapid progress of the bike. Various forms of bicycles successfully created.

THEORY EVOLUTION FROM CHARLES DARWIN

Evolutionary theory was pioneered by a zoologist named Charles Robert Darwin (1809-1882). The theory that says: A body (material) experienced a change from an imperfect toward perfection. Then he expanded his theory was to come to the origin of man. According to human beings today is the most perfect result of these developments on a regular basis by the laws of mechanics as well as plants and animals. Then was born a teaching / understanding that human beings have now is a result of evolution of great apes (human apes to walk upright) for years and have reached the most perfect.Theory form of Darwin in his book entitled "The Origin of Species" huge success because it can be said to discuss issues pertaining to human origins.
Inside Darwin's theory argued that human beings originated from the development of a simple kind of apes evolved into ape animal high level until it becomes human. The oldest living creature with human-like form is Australopithecus, which estimated his age between 350000-1000000 year with a brain size of about 450-1450 cm3. Development with changes in brain volume was greater the effect on human intelligence. Australopithecus who have an average brain volume of 450 cm3 apes evolved into humans (Neanderthals) who has a brain volume of 1450 cm3. From this study are expected in the time between 400000-500000 years that brain volume increased in 1000 cm3.

SPIRAL GALAXY

The galaxy is a gathering place of stars in the universe. Almost did not find any star that wanders alone in the space between galaxies. And Sun are among 200 billion stars in our Milky Way galaxy (abbreviated with Galactic). Assuming that the average mass of stars in the galaxy is the Sun's mass, the mass of the galaxy can reach 2 x 10 ^ 11 solar masses (the mass of the Sun is 2 x 10 ^ 30 kg).
Milky Way galaxy shapes such as two concave plates are cupped, thick middle part and increasingly flattened towards the edge, and there are spiral arms in it. Therefore, our galaxy is classified into a spiral galaxy. Based on the Hubble galaxy classification, including the Milky Way galaxy SBbc class. This means that our galaxy is a spiral galaxy that has a "bar" or the crossbar in the center, with the brilliance of the central section is relatively similar to the disc, and has a spiral arm structure is somewhat tenuous at the rotation.
Spiral galaxies are composed of three main parts, namely the bulge, halo, and disc. All three have the shape, size, and objects of different authors. In fact, the bulge and disc to be determinant in the classification made by the Hubble galaxy (diagram of a tuning fork). Regions in parts of the galaxy bulge is the most high-density star. stellar halo are stars that are in the halo. But few individual stars found in this section. The more dominant is the group of old stars that the number of member stars reach the millions of pieces, called globular clusters .On the disc there are young stars and interstellar gas and dust located in the spiral arms.

ALEXANDER FLEMING (DISCOVERER OF PENICILLIN)

Sir Alexander Fleming (6 August 1881 - 11 March 1955) was the man known as the discoverer of penicillin (an antibiotic to fight bacteria). Born on a farm near Darvel Lochfield, Scotland. He was the third of four brothers and half-brother has four people again.
Fleming went to Loudoun Moor School and Darvel School, and then for two years he attended Kilmarnock Academy. After working in an office delivery service for four years, 20-year-old Fleming was partly inherited from his uncle's property.
Fleming's brother, who was then a doctor suggested that his younger brother following in the footsteps of his career, so that Alexander Fleming in 1901 and then enrolled at the Hospital of St. Mary's, London. He then obtain a special qualification for school in the year 1906 with an option to be a surgeon. Alexander Fleming himself famous because she is an expert researcher who is very clever, but the lab itself is often clumsy and look messy.
In 1928, after coming home from a long holiday, Fleming will afterthought in the disc of bacteria in the laboratory forgot to save it nicely, and has been contaminated with a type of mushroom. Some laboratory dish containing the bacteria in the waste, but then Fleming noticed that the growth of bacteria in the contaminated by the fungus becomes obstructed. Fleming then took samples of examples of these fungi and examine it, he discovered that the fungus is from the genus Penicillium. This is why the drug called penicillin.
Fleming's discovery in September 1928 marked a new century in the world of modern antibiotics. Fleming also found that the bacteria themselves can develop resistance and resistance to penicillin when penicillin is used as an antibiotic is too little and used in the short term.

IDENTICAL TWINS

Identical twins are also called Monozygotic twins, ie twins come from one egg. Have the same genes, same sex and similar advances.
The process of identical twinning is due at the time of fertilization of a mature egg cell by a
sperm fertilization helps zygote, then this zygote will divide.
If cleavage occurs when the zygote is the beginning of fertilization (1-3 days after fertilization), each embryo will usually have different amniotic sack, and one placenta.
But when the division occurred after 14 days then the twins will probably happen join / stick together on the part of the body or cleavage is not perfect so-called Siamese twins higher. So the twins conjoined twins occur in monozygot. With ultrasound (utrasonografi) physicians will be able to assess the state of the fetus, gender, and position defects.

SHELL PRODUCER PEARL


In principle, the chance of shelled mollusks produce pearls naturally. However, not all oysters can produce pearls are nice and have bought a decent value. Pearl mussel producers generally come from families Pteriidae, but are commonly known only certain types such as gold or silver-lip pearl oyster Pinctada maxima, the black-lip pearl oysters Pinctada margaritifera, Akoya pearl oysters Pinctada fucata and the winged-pearl oyster Pteria penguins.
All members of this family live in the sea. While other mollusks that produce pearls known so far from the group of abalone and a few other gastropods as well as several types of freshwater bivalve shellfish. Each type of pearl oysters produce pearls with different specifications. Pinctada maxima produces relatively larger pearls of all types of shellfish-producing pearls, silver, gold and cream.
This species is much cultivated in Indonesia, Burma, Thailand and Australia. While the shells of Pinctada margaritifera is the belle of the south pacific countries. The resulting pearl color varies from beige to black. The black color is the color of pearls customer demand world today. Thus they were very expensive. The diameter of the pearls produced are generally smaller than that produced by Pinctada maxima.
While Pinctada fucata is the kind that many cultivated in Japan, and Pteria penguin is not much cultivated because so far the results in certain circles, destined only to remember the form of pearls they produce are generally not circular

OCEANOGRAPHY


Oceanography consists of two words: oceanos which means sea and graphos which means the picture or description (in Greek). In simple terms we can interpret as a picture or a description of the oceanography of the sea. In another language more complete, oceanography can be defined as the study and exploration of the sea and all the scientific phenomenon. Sea itself is part of the hydrosphere. As we all know that the earth consists of solid part, called the lithosphere, the hydrosphere and the liquid is called the gas called the atmosphere. Meanwhile, the ecological system associated with all living inhabitants of planet Earth into the biosphere grouped.
In general, oceanography can be grouped into 4 (four) main disciplines, namely: geological oceanography who study the ocean floor or the lithosphere beneath the sea, physical oceanography that studies physical problems such as ocean currents, waves, tides and sea water temperature, chemical oceanography are studying the problems of sea water chemistry and the latest biological oceanography that studies issues relating to the flora and fauna in the sea.
Comprehensive study about the first time with the sea started doing the Challenger expedition (1872-1876) led by a naturalist named CW Thomson (Scottish) and John Murray (Canadian nationals). Oceanography own term used by those in a report edited by Murray. Murray went on to become leaders in the study of marine sediments. Success of the Challenger expedition, and the importance of marine science in the shipping / marine transportation, fishery, marine cables, and the study of climate eventually led many countries to conduct subsequent expeditions. The first international oceanographic organization is The International Council for the Exploration of the Sea (1901).

ELECTROCARDIOGRAPHY HISTORY


Alexander Muirhead is reported to have attached wires to a feverish patient's wrist to obtain a record of the patient's heartbeat while studying for his Doctor of Science (in electricity) in 1872 at St Bartholomew's Hospital. This activity was directly recorded and visualized using a Lippmann capillary electrometer by the British physiologist John Burdon Sanderson.
The first to systematically approach the heart from an electrical point-of-view was Augustus Waller, working in St Mary's Hospital in Paddington, London. His electrocardiograph machine consisted of a Lippmann capillary electrometer fixed to a projector. The trace from the heartbeat was projected onto a photographic plate which was itself fixed to a toy train. This allowed a heartbeat to be recorded in real time. In 1911 he still saw little clinical application for his work.
An initial breakthrough came when Willem Einthoven, working in Leiden, Netherlands, used the string galvanometer that he invented in 1903. This device was much more sensitive than both the capillary electrometer that Waller used and the string galvanometer that had been invented separately in 1897 by the French engineer Clément Ader.Rather than using today's self-adhesive electrodes Einthoven's subjects would immerse each of their limbs into containers of salt solutions from which the ECG was recorded.
Einthoven assigned the letters P, Q, R, S and T to the various deflections, and described the electrocardiographic features of a number of cardiovascular disorders. In 1924, he was awarded the Nobel Prize in Medicine for his discovery.
Though the basic principles of that era are still in use today, there have been many advances in electrocardiography over the years. The instrumentation, for example, has evolved from a cumbersome laboratory apparatus to compact electronic systems that often include computerized interpretation of the electrocardiogram.

INSOMNIA


Insomnia is a sleep disorder symptoms such as difficulty sleeping or repeatedly to maintain sleep even though there is a chance for that. The symptoms are usually followed by functional impairment while awake.
Insomnia is often caused by a disease or a result of psychological problems. In this case, medical or psychological assistance will be required. One of psychological therapy is effective insomnia cognitive therapy .In handle these therapies, a patient is taught to improve sleep habits and eliminate counter-productive assumptions about sleep.
Many people with insomnia depending on sleeping pills and other sedative substances to be rested. All of sedative drugs have the potential to cause psychological dependence in the form of assuming that they can not sleep without the drug.

COLOSSEUM


Colosseum is a historical relic in the form of a large theater / Amphitheatre which is one of the "Seven Wonders of the Medieval World." Located in the State Capital of Italy, Rome, called the original "Flavian Amphitheatre", founded by King Vespasian and completed by his son Titus.
About the year of manufacture is still no difference conviction. Some argue that the Colosseum was built in 79 BC, there is also a notion that was made between the years 70-82 AD. But, most archaeologists believe that the Colosseum was built in 70-82 AD Origin of the name Colosseum was derived from a sculpture as tall as 130 feet or 40 m, named Colossus. Colosseum is set to accommodate 50,000 spectators.




GREAT SPHINX OF GIZA


Great Sphinx of Giza is a large sphinx statue shaped half-human, half lion found in Egypt, at Giza Plain, the west bank of the Nile, near Cairo now. This is one of the few in the world's largest sculpture made of one piece of stone, and is believed to have been built by ancient Egyptians in the third millennium BC. The name used for the people of Ancient Egypt to refer to this statue is not known. The name 'sphinx' which is used is taken from a Greek mythology creature with the body of a lion, a woman's head and wings of an eagle, though Egyptian sphinxes have the head man.
The word "sphinx" comes from the Greek (Σφιγξ - Sphinx, from the verb σφιγγω - sphingo) which means to strangle, because the sphinx from Greek mythology to strangle people who can not answer the riddle. For some people, it is believed that this name represents a change in words from the ancient Egyptian language Shesep-Ankh, a name given to the royal statues in the Fourth Dynasty. In medieval writings, and bilhaw balhib name that points to the Sphinx is used, including by Egyptian historian Maqrizi, who suggested the preparation of the Coptic language, but the term Arab-Egypt Abul-Hol, which translates as "Father of Terror," more widely used. although the means "Father of Terror", the sphinx is one of the modern culture of his day, and is a popular tourist area.

THE EGYPTIAN PYRAMID

The pyramids of Egypt fascinated travellers and conquerors in ancient times and continue to inspire wonder in the tourists, mathematicians, and archeologists who visit, explore, measure and describe them.
Tombs of early Egyptian kings were bench-shaped mounds called mastabas . Around 2780 BC, King Djoser's architect, Imhotep, built the first pyramid by placing six mastabas, each smaller than the one beneath, in a stack to form a pyramid rising in steps. This Step Pyramid stands on the west bank of the Nile River at Sakkara near Memphis. Like later pyramids, it contains various rooms and passages, including the burial chamber of the king. The transition from the Step Pyramid to a true, smooth-sided pyramid took placed during the reign of King Snefru, founder of the Fourth Dynasty (2680-2560 BC). At Medum, a step pyramid was built, then filled in with stone, and covered with a limestone casing. Nearby at Bahshur, construction was begun on a pyramid apparently planned to have smooth sides. About halfway up, however, the angle of incline decreases from over 51 degrees to about 43 degrees, and the sides rise less steeply, causing it to be known as the Bent Pyramid. The change in angle was probably made during construction to give the building more stability. Another great pyramid was built at Dahshur with its sides rising at an angle of somewhat over 43 degrees, resulting in a true, but squat looking pyramid.
The largest and most famous of all the pyramids, the Great Pyramid at Giza, was built by Snefru's son, Khufu, known also as Cheops, the later Greek form of his name. The pyramid's base covered over 13 acres and its sides rose at an angle of 51 degrees 52 minutes and were over 755 feet long. It originally stood over 481 feet high; today it is 450 feet high. Scientists estimate that its stone blocks average over two tons apiece, with the largest weighing as much as fifteen tons each. Two other major pyramids were built at Giza, for Khufu's son, King Khafre (Chephren), and a successor of Khafre, Menkaure (Mycerinus). Also located at Giza is the famous Sphinx, a massive statue of a lion with a human head, carved during the time of Khafre.
Pyramids did not stand alone but were part of a group of buildings which included temples, chapels, other tombs, and massive walls. Remnants of funerary boats have also been excavated; the best preserved is at Giza. On the walls of Fifth and Sixth Dynasty pyramids are inscriptions known as the Pyramid Texts, an important source of information about Egyptian religion. The scarcity of ancient records, however, makes it difficult to be sure of the uses of all the buildings in the pyramid complex or the exact burial procedures. It is thought that the king's body was brought by boat up the Nile to the pyramid site and probably mummified in the Valley Temple before being placed in the pyramid for burial. There has been speculation about pyramid construction. Egyptians had copper tools such as chisels, drills, and saws that may have been used to cut the relatively soft stone. The hard granite, used for burial chamber walls and some of the exterior casing, would have posed a more difficult problem. Workmen may have used an abrasive powder, such as sand, with the drills and saws. Knowledge of astronomy was necessary to orient the pyramids to the cardinal points, and water-filled trenches probably were used to level the perimeter. A tomb painting of a colossal statue being moved shows how huge stone blocks were moved on sledges over ground first made slippery by liquid. The blocks were then brought up ramps to their positions in the pyramid. Finally, the outer layer of casing stones was finished from the top down and the ramps dismantled as the work was completed.
Most of the stone for the Giza pyramids was quarried on the Giza plateau itself. Some of the limestone casing was brought from Tura, across the Nile, and a few of the rooms were cased with granite from Aswan. Marks of the quarry workers are found on several of the stone blocks giving names of the work gangs such as "craftman-gang". Part-time crews of laborers probably supplemented the year-round masons and other skilled workers. The Greek historian Heroditus reported in the fifth century BC that his Egyptian guides told him 100,000 men were employed for three months a year for twenty years to build the Great Pyramid; modern estimates of the number of laborers tend to be much smaller.
Pyramid building was at its height from the Fourth through the Sixth Dynasties. Smaller pyramids continued to be built for more than one thousand years. Scores of them have been discovered, but the remains of others are probably still buried under the sand. As it became clear that the pyramids did not provide protection for the mummified bodies of the kings but were obvious targets for grave robbers, later kings were buried in hidden tombs cut into rock cliffs. Although the magnificent pyramids did not protect the bodies of the Egyptian kings who built them, the pyramids have served to keep the names and stories of those kings alive to this day.

OZONE IN THE ATMOSPHERE


Ozone is a strong oxidant substances, toxic substances and micro-organism killer which is also strong. Ozone is commonly used to sterilize water refill, and can also be used to remove color and unpleasant smell in the water.
Ozone is formed naturally in the stratosphere. The formation and destruction of ozone in the stratosphere is protective mechanism of the earth from UV rays from the sun. In tropospheric ozone is formed through photochemical reactions in the various air pollutant substances. Ozone layer is found in the stratosphere and also in the troposphere layer. Ozone is found in the stratosphere protects humans working and living on the earth from UV radiation light. While ozone is present in tropospheric layer has a different effect on the earth and the creatures living in it, even though the same chemical composition. This tropospheric ozone is toxic and is one of the greenhouse gases. In addition, tropospheric ozone also cause damage to the plants, paint, plastics and human health.
Ozone O3 has chemical formula, chemical formula resembles O2 oxygen molecule with an oxygen atom more. At room temperature the form of ozone gas, condensing at a temperature of -112 oC to liquid blue. This liquid ozone will be frozen at -251.4 oC, while at temperatures above 100 oC ozone decompose quickly.
From molekol O2, by the reaction. Ozone is formed will be back breaks into oxygen molecules. In nature, formation and destruction of ozone is in a state of balance, so that ozone levels are in dynamic balance. Both these reactions can effectively block UV rays and extreme UV-C and most UV-B rays to reach the earth. This is the natural mechanism that protects the earth and its inhabitants from the short-wave UV radiation harmful to life. Both these reactions also lead to rising temperatures in the stratosphere than the temperature in the troposphere. Approximately 3 billion years ago, as a result of evolution on earth emerged berklorofil living thing, begin the process of photosynthesis that occurs one result is O2. the longer, higher levels of O2, thus increasing levels of ozone that is formed. Thus, the more UV rays short gelombnag blocked by the ozone layer to reach the surface of the earth. And this is the forerunner of life on land.
However, over time, the number of population and industrial progress and development resulted in the ozone layer is starting hole. Ozone hole is very worrying because the reduction in ozone means kada increased UV-B rays that will reach the earth. The impact of increased UV-B rays can be very big on living things on earth.
Occurrence of the ozone hole was the result of increased levels of NOx from aircraft fuel burning, increased levels of N2O as a result of biomass burning and fertilizer oenggunaan, which is a source of N2O formation of NO.
In addition, the chemicals that we know clorofuorocarbon or CFCs had an enormous impact on ozone destruction. CFCs are a class of chemicals consisting of three types unrus, namely chlorine (Cl), fluorine (F) and carbon (C). CFC is the dominating problem of ozone destruction and become a substance that is suspected as the cause of ozone destruction. CFCs are not found in nature, but rather is an intermediate result of human engineering. CFCs are not toxic, does not burn and is very stable because it is not easy to react. Therefore become an ideal material for the industry. CFCs are widely used as a cooling agent in refrigerators and car air-conditioning (CFC-12), as a material for making plastic foams, seat cushions and car seats (CFC-11), a mixture of CFC-11 and CFC-12 used for driving aerosols, and CFC -13 commonly used in dry cleaning.

BERMUDA TRIANGLE SECRET


Dozens of planes and ships are listed as in missing the Bermuda Triangle without a known trail throughout the year. The aircraft Star Tiger, without cause - for a clear and without sending any signal, arrived - arrived disappeared on January 30, 1948, on his way to Bermuda with 31 passengers. Another incident on December 28, 1948, a DC-3 aircraft with 35 passengers flying from the waters above Poertorico missing Bermuda Triangle. On January 17, 1949 Area Star aircraft, from the direction of Bermuda to Jamaica just disappear swallowed by the earth without a trace.
Bermuda term derived from the name of the seventh month of the Egyptian calendar, which is Naisan. In that farmers plant and harvest sugar cane dates. The term was later used to refer to imaginative triangle located in the Atlantic Ocean. Bermuda Triangle has an area of about 770,000 km2 and consists of group of islands - islands which number 350 islands. Peak imaginative Bermuda, in the north of the island of Bermuda there, there south east corner Poerterico island, which is the U.S. military headquarters. Inhabitants speak Spanish and English the official language. The capital of San Juan. While western corner is located in Miami, Florida.
A specialist event - a mysterious event called Vincent Cadys marine, said that the Bermuda Triangle area is very dangerous to shipping and aviation. Approximately 100 aircraft and ships lost in this area and the victim reached more than 1000 people. Most of the mysterious events that occurred in 1945.
Then, Charles Berlins, Bermuda Triangle author of the book describes at length in his book about the loss of French ships passing through the area Rousalie in the year 1940. The engine is still good and its cargo was not disturbed, but the ship is not empty or manned passengers. Another incident is the loss of a large freighter named Anita's USA with a cargo of 20,000 tons on March 23, 1973.
The most horrible event dubbed "Atlantic Cemetery" on the Bermuda Triangle is a calamity that had befallen the expedition-19 squadron to the United States. On Thursday, January 1945, five aircraft types Finger TTB30 departing from his base in Port Louderdidle in the Florida, USA. Fifth plane with its crew disappeared under mysterious fog without leaving a trace in the Bermuda Triangle.
What is even more remarkable efforts of scholars in solving the mystery of the Bermuda Triangle, that area there dinterpretasikan electromagnetic events - events such as the repetition of the interface back events - events that once occurred in the area because of the passage of time (time tannel). So the plane and the missing ships were still alive but was in place and another time.
Other responses about the Bermuda Triangle is a regional center of the kingdom was the devil and Satan followers - followers to control human activities in order to influence the error, according to his promise to the prophet before Adam to be decadent descendants of Adam.

BLACK HOLES


Black holes are the evolutionary endpoints of stars at least 10 to 15 times as massive as the Sun. If a star that massive or larger undergoes a supernova explosion, it may leave behind a fairly massive burned out stellar remnant. With no outward forces to oppose gravitational forces, the remnant will collapse in on itself. The star eventually collapses to the point of zero volume and infinite density, creating what is known as a " singularity ". Around the singularity is a region where the force of gravity is so strong that not even light can escape. Thus, no information can reach us from this region. It is therefore called a black hole, and its surface is called the " event horizon ".
But contrary to popular myth, a black hole is not a cosmic vacuum cleaner. If our Sun was suddenly replaced with a black hole of the same mass, the Earth's orbit around the Sun would be unchanged. (Of course the Earth's temperature would change, and there would be no solar wind or solar magnetic storms affecting us.) To be "sucked" into a black hole, one has to cross inside the Schwarzschild radius. At this radius, the escape speed is equal to the speed of light, and once light passes through, even it cannot escape.

The Schwarzschild radius can be calculated using the equation for escape speed:
vesc = (2GM/R)1/2

For photons, or objects with no mass, we can substitute c (the speed of light) for Vesc and find the Schwarzschild radius, R, to be:
R = 2GM/c2
If the Sun was replaced with a black hole that had the same mass as the Sun, the Schwarzschild radius would be 3 km (compared to the Sun's radius of nearly 700,000 km). Hence the Earth would have to get very close to get sucked into a black hole at the center of our Solar System

MAMMOTHS


Genus Mammoths:
The genus mammoths, in latin Mammuthus, was a group of species, belonging to the family of elephants, entirely separated in taxonomy from the Mastodons and the genus family Mammutidae, although they sometimes shared the same envoronment. (For scientific reasons, the mastodons was renamed to family Mammutidae, which became a source for future confusion and misunderstandings). The Mammoths probably has origin from Stegodon and started to develop during upper Pliocene, (some 4 million years ago) in africa, spred to europe and asia, and Mammuthus meridionalis went over Bering Strait to north america about 1.8 million years ago, (the wooly Mammoth went over much later) and became extinct during lower Holocene, probaby exterminated by prehistoric humans who hunted elephants and Mammoths and made huts and houses out of their bones.

Caracters of Mammoths :
• They had bumps on their head .
• Both sexes had tusks .
• Some tusks were straight, some were curved .
• The longest tusks were up to 13 feet (4 m) long .
Mammoths had longer tusks than Mastodons, a wider head, a sloping back and flat chewin
teeth .
• Their trunk had two finger-like projections like african elephants .
• Their teeth were flat like asian elephants .
• Most species was not larger than recent elephants .

THE MUMMY


The mummy is a corpse is preserved, due to protection from decomposition by natural or artificial means, so that the first form is maintained. This can be achieved by placing the body in a very dry or very cold, or lack of oxygen, or the use of chemicals.

The most famous mummy balm smeared with specific conservation goals, especially in ancient Egypt. The Egyptians believed that the body is where he is a very important person in the after life.

In China, have been found from cypress coffin that sunk by using medicinal plants.

Mummies that formed due to natural events, such as in the super-cold (Ötzi the ice man, acid (Tollund human) or drought found in many places in the world. Some of the best preserved mummy in a natural condition starts since the Inca period in Peru.
