2012 Mayan Calender
Monday, November 23, 2009
Do you think the world will culminate soon? Well, this is the prediction that the Mayan calendar tells about the future. So what is the 2012 Mayan Calendar all about? It is actually made up of two different calendars namely Tzolk'in and Haab. You will find 260 days in the Tzolk'in calendar and 365 days in the Haab calendar. Both these calendars combined together will make a big cycle of fifty two years, called as a Calendar Round.
What is the effect of Mayan Calendar on you?
When you study about the 2012 Mayan Calendar, you will get to know about numerous predictions about the future. Information available in the calendar are always accurate, be it time for sunrises or sunsets. Mayans are extremely skilled in creating a lot of calendars. If you make a detailed study about the Mayan Calendars, you will find a prediction saying that the world will culminate on December 21, 2012. But this prediction is becoming a matter of question for many people. So in this post I will be trying to tell about Maya Culture and Maya Calender and will also discuss illusion regarding Maya Calender.
Maya Culture
The Mayan culture has undergone substantial changes throughout its existence. It is part of the wider context of Mesoamerican civilization that stretched from Central America into the present-day southern United States. This civilization was based on the cultivation of maize and shared the sacred 260-day calendar. It is estimated that the Maya started to cultivate maize about 5000 years ago, around the time set for the beginning of their Long Count. It is however only about the time of Christ that we can talk about the emergence of a high culture among the Maya.
The Mayan Calender
The Mayan calendar is associated with nine creation cycles, which represent nine levels of consciousness or Underworlds as symbolized by the Mayan pyramids. This pyramidal structure of consciousness development can explain things as disparate as the common origin of world religions and the modern complaint that time seems to be moving faster.
Time, in fact, is speeding up as we transition from the materialist Planetary Underworld that still governs us to a new and higher frequency of consciousness, the Galactic Underworld, in preparation for the final Universal level of conscious Enlightenment.
The Mayan calendar is thus a spiritual device that enables a greater understanding of the evolution of consciousness driving human history and the concrete steps we can take to align ourselves with this cosmic evolution toward Enlightenment.
The Mayan Use of the Calendar
In addition to its role as a contact to the ancestors, the Maya used the calendar for celebrating significant energy shifts. At these times the shaman kings would make prophecies about the time ahead in the new energy. A base of knowledge had been created as to how the energies would shift according to the calendar, and, in combination with the shamanic connection to the World Tree, prophecies of relevance to the present moment and the immediate time ahead were developed.
The aspect of the Mayan calendar system that has survived to the present time is the uninterrupted use of the Sacred Calendar of 260 days. Mayan day-keepers daily pray to the Creator and perform ceremonies that honor the day signs. Among the living Maya the 260-day calendar has various roles:
- To keep track of the energies of the day,
- To calculate birth energies of different individuals,
- To determine the celebration of holidays,
- To base healing practices on,
- For prophecy, and
- For divination of individual destinies.
The Mayan Calendar End date
Many people hear about the so-called end date of the Mayan calendar, and today some people have even created the illusion that the Mayan calendar was designed only to point out this end date. In reality, there is nothing to indicate that the ancient Maya who developed the Long Count calendar had any interest in what would happen as this calendar came to an end. Instead what the ancient Mayan scriptures talk about is its beginning. The exact date for this beginning was apparently based on the day of the year, August 11, when the sun was in zenith in Izapa, where most likely this calendar first came into use. Ancient Mayan inscriptions also talk about this time as the time when the First Father erected the World Tree so that the light could enter, a significant event in creation. The various dynasties in the different Mayan city-states would then try to track a relationship to this seminal event by First Father and legitimize their power based on this.
The fact that the Mayan Long Count was based on the day the sun was in zenith in Izapa, has however created a very significant misunderstanding among modern people, and this is that it would end on December 21, 2012. The particular date the sun is in zenith in this location obviously has no relevance in the rest of the world, but because of the power of tradition some will still adhere to it. In reality, the creation cycle that began as the First Father erected the World Tree will end on October 28, 2011. This day is also 13 Ahau in the sacred Mayan calendar, an energy with great prophetical relevance.

SAHARA - World's Biggest Desert
Wednesday, November 4, 2009
The Sahara, with a size of 8.6 million km²(3,500,000 sq mi), is the world's largest desert. It covers most of Northern Africa, making it almost as large as the United States or the continent of Europe. Around 4 million people live here. Its maximum length is 4,800 km, running from west to east, and up to 1,200 km from north to south. Sahara covers most of Mauritania, Western Sahara, Algeria, Libya, Egypt, Sudan, Chad, Niger and Mali, and touches Morocco and Tunisia.To the north, Sahara is bordered by the Atlas Mountains and the Mediterranean Sea; in the west by the Atlantic Ocean; in the south, the desert zone reaches 16º northern latitude; in the east it is bordered by the Nile. Still the desert continues to the east of the river until it reaches the Red Sea, but this is not considered a part of the Sahara.
Sand sheets and dunes represent about 25% of the Sahara; the other parts are mountains, stoney steppes and oases. Pyramidal dunes can be as high as 150 metres, while mountainous sand ridges as high as 350 metres.
There are several rivers running through the Sahara, of which the Nile River and Niger River are the only permanent ones. The rest being seasonal, involves that most of the time, there is only a dry river bed, which may carry water for brief periods following uncommon rainfalls. There may be years in between this happening.
Amazing Facts Of Sahara Desert:
- World's largest Hot desert covering around 9,00,000 square km.
- Although being a desert area, one can notice annual rainfall in many regions of this vast land area. There are different climates witnessed in different regions.
- This hot desert has annual temperatures. Some of the hottest months have temperatures exceeding 50 degrees C. In the winters, the temperatures drop below freezing points. This itself explains the diverse climates of this hot desert.
- Observations made with the help of satellite photographs have proven this desert can shrink or even grow in size.
- This desert has some of the tallest sand dunes and these can reach 189 meters in height. The land area also has stone plateaus, large gravel plains, dry valleys and even sand flats.
- The Sahara desert has around 500 species of flora.
- Emi Koussi is the highest peak that is seen in the Tibesti Mountains. This peak has a height of 3415 m.
- This mysterious and vast place also has some of the most magnificent landscapes and despite harsh weather, it has attracted people to study details associated with the Sahara desert. This desert is more than a hot and dry place, it is one of the most remarkable areas known to man!
Climate History of Sahara: How it was formed
The climate of the Sahara has undergone enormous variation between wet and dry over the last few hundred thousand years. During the last glacial period, the Sahara was even bigger than it is today, extending south beyond its current boundaries. The end of the glacial period brought more rain to the Sahara, from about 8000 BC to 6000 BC, perhaps due to low pressure areas over the collapsing ice sheets to the north.
Once the ice sheets were gone, northern Sahara dried out. But in southern Sahara, the drying trend was soon counteracted by the monsoon, which brought rain further north than it does today. The monsoon is due to heating of air over the land during summer. The hot air rises and pulls in cool, wet air from the ocean, which causes rain. Thus, though it seems counterintuitive, the Sahara was wetter when it received more solar insulation in the summer. This was caused by a stronger tilt in Earth's axis of orbit than today, and perihelion occurred at the end of July.
By around 3400 BC, the monsoon retreated south to approximately where it is today, leading to the gradual desertification of the Sahara. The Sahara is now as dry as it was about 13,000 years ago. These conditions are responsible for what has been called the Sahara pump theory. Half of the Sahara receives less than 2 centimetres (0.79 in) of rain per year, and the rest receives up to 10 cm (3.9 in) per year.
10 Amazing Species - About to Disappear!!
Tuesday, November 3, 2009
1.Slender Loris
The slender loris, Loris tardigradus is classified as Endangered (EN A2cd+4cd) on the IUCN Red List 2004. The grey slender loris, Loris lydekkerianus is classified as Near Threatened (NT) on the IUCN Red List 2004. Two subspecies of slender loris, Loris tardigradus exist.
The most distinguishing characteristics of the slender lorises are their very long, slender arms and legs, which give these species their names. They usually have a grey or reddish coat, although this varies according to subspecies, and the fur is soft, thick and woolly. Slender lorises do not have tails and move on all fours climbing or walking along branches. They do not have truly opposable thumbs and are only able to grasp things like food or branches with the whole hand, though they do have an extremely powerful grip. The eyes are large and round and the prominent ears are thin, rounded and naked at the edges. There is much confusion over slender loris classification.
2. Yangtze River Dolphin -BaijiIt is/was a freshwater dolphin found only in the Yangtze Riverin China. Nicknamed "Goddess of the Yangtze" in China, the dolphin was also called Chinese River Dolphin, Yangtze River Dolphin, Whitefin Dolphin and Yangtze Dolphin.
According to Chinese legend, this graceful freshwater dolphin is the reincarnation of a drowned princessThe 2007 IUCN Red List classifies the Baiji as extinct. The Baiji population declined drastically in recent decades as China industrialized and made heavy use of the river for fishing, transportation, and hydroelectricity.
The baiji is a graceful freshwater dolphin, characterised by a very long, slightly upturned beak and low triangular dorsal fin. Like other river dolphins, it has little need for vision in the muddy waters it inhabits, and as a result has tiny, barely functional eyes. It is pale blue-grey in colour with a white underside. The female is generally larger than the male.
3. Attenborough's long-beaked echidna
Recently classified as three separate species, long-beaked echidnas belong to an ancient clade of egg-laying mammals that includes the platypus of Australia. They are easily distinguished from short-beaked echidnas by their long snouts, which account for two-thirds of the length of the head. Despite laws designed to protect these species, they are in decline in areas accessible to humans. Echidnas have lost much of their forest habitat to logging, mining and farming, and are regarded as highly prized game animals by local people. Size: Head and body length: 450-775 mm and Weight: 5-10 kg.
The most distinguishing feature of long-beaked echidnas is their long snouts, which curve downwards and account for two-thirds of the length of the head. They have no teeth; instead their tongues are covered in spikes (teeth-like projections), which are very effective in hooking prey and drawing it into the mouth. They have compact, muscular bodies, with strong limbs and claws for digging. Their back and sides are covered with spines, which vary in colour from white through to dark grey or black. The body is also covered in brownish-black hairs, which sometimes hide the spines. Males are larger than females and have spurs on the inside of the hind limbs, near the foot.

4. Hispaniolan solenodon
It weighs between 0.6 and 1.0 kg, and is 28 to 33 cm long (the tail measures an extra 25 cm). It has brownish-red fur on most of its body, the underside being a lighter shade. The tail, legs, snout and eartips are hairless. The forelegs are noticeably more developed than the hind ones, but all have strong claws useful for digging. The head is very big in relation to its body, and it has a long rostrum with tiny eyes and ears, partially hidden by the body fur.
5. Bactrian Camel The Bacterian camel (Camelus bactrianus) is a large even-toed ungulate native to the steppesof north eastern Asia. It is one of the two surviving species of camel. The Bactrian Camel has two humps on its back, in contrast to the single-humped Dromedary Camel. Nearly all of the estimated 1.4 million Bactrian Camels alive today are domesticated, but in October 2002 the estimated 950 remaining in the wild in northwest China and Mongolia were placed on the critically endangered species list.
6.Pygmy Hipopotamus
6.Pygmy Hipopotamus
The pygmy hippopotamus (Choeropsis liberiensis or Hexaprotodon liberiensis) is a large mammal native to the forests and swamps of western Africa (the scientific species classification means "of Liberia", as this is where the vast majority live). The pygmy hippo is reclusive and nocturnal. It is one of only two extant species in the Hippopotamidae family, the other being its much larger cousin the common hippopotamus.
The pygmy hippopotamus displays many terrestrial adaptations, but like its larger cousin, it is semi-aquatic and relies on proximity to water to keep its skin moisturized and its body temperature cool. Behaviors such as mating and giving birth may occur in water or on land. The pygmy hippo is herbivorous, feeding on whatever ferns, broad-leaved plants, grasses and fruits it finds in the forests.

7. Long eared jerboa
The Long-eared Jerboa, Euchoreutes naso, is anocturnal mouse-like rodent with a long tail, long hind legs for jumping, and exceptionally large ears. It is distinct enough that authorities consider it to be the only member of both its genus, Euchoreutes, and subfamily, Euchoreutinae.
It has been reported in China and in ten localities in desert habitats of Trans Altai Govi Desert and the Gobi Desert in Mongolia. A large part of the species is believed to occur in Mongolia within protected areas. Very little is known about the species.

Kitti's Hog-nosed Bat(Craseonycteris thonglongyai), also known as the bumblebee bat, is about 29–33 millimetres (1.14–1.30 in) in length and 2 grams (0.07 oz) in mass), hence the common name of "bumblebee bat". It is the smallest species of bat and may be the world's smallest mammal. It is a vulnerable species of bat and the only member of the family Craseonycteridae. It occurs in western Thailand and southeast Burma, where it occupies limestone caves along rivers.
Kitti's Hog-nosed Bat is the smallest species of bat and one of the world's smallest mammals. It has a reddish-brown or grey coat, with a distinctive pig-like snout. Colonies range greatly in size, with an average of 100 individuals per cave. The bat feeds during short activity periods in the evening and dawn, foraging around nearby forest areas for insects.
9.Golden Rumped Elephant shrew
The Golden-rumped Elephant Shrew (Rhynchocyon chrysopygus) is the largest of the African elephant shrew family. It is the size of a small rabbit, and is only found in the coastal Arabuko Sokoke National Park north of Mombassa in Kenya.
The Golden-rumped Elephant Shrew lives on the forest floor of evergreen forests, rooting through the leaf litter for 80% of the waking day looking for grasshoppers, beetles, spiders and other small invertebrates.9.Golden Rumped Elephant shrew
The Golden-rumped Elephant Shrew (Rhynchocyon chrysopygus) is the largest of the African elephant shrew family. It is the size of a small rabbit, and is only found in the coastal Arabuko Sokoke National Park north of Mombassa in Kenya.
It is very fast, capable of running at 25km/h. When it detects a predator within its 'flight distance' it will bound off. If, however, the predator is outside its flight distance the elephant shrew will advertise its presence by slapping the leaf litter. As a final precaution each shrew has several nests which it maintains, thus a predator finding a nest will not learn to associate them with potential food.
10. Hirola
The Hirola (Beatragus hunteri, sometimes Damaliscus hunteri also known as Hunter's Hartebeest) is an antelope species found in arid grassy plains in a pocket on the border between Kenya and Somalia. It's the only member of the genus Beatragus.
Hirola are known as the "four-eyed antelope," due to their large preorbital glands. Hirola stand 100 to 125 centmetres at the shoulder and weigh 80 to 118 kilograms. Their coat is a sandy brown colour, greyer in males than females, with a lighter underbelly and a small white strip over the bridge of the nose. The nape of the neck has very thick skin which forms ridges when the ears are pricked up. The horns are lyre shaped and very conspicuously ringed.

Formation Of Earth - An Amazing History
Thursday, October 29, 2009
The theory which explain the origin of earth and this Universe is called Big Bang Theory. According to this theory all matter in the Universe was, at one time, concentrated in a giant mass (a black hole?) that blew apart about 10 to 20 billion years ago (bya) and is still expanding.
It is thought that our solar system had its origins when, about 5 bya, triggered by some unknown cause, a cloud of interstellar dust and gases collapsed and condensed. Some of the matter in the central mass contracted under its own gravity, condensed, and heated until forces were so strong that thermonuclear reactions began, and this was the origin of our star, the Sun.
Origin of Planets:
About 4.6 to 4.5 billion year ago, a disk-shaped cloud of subsidiary smaller lumps, pieces, dust, gases, etc. orbiting the sun subsequently coalesced and condensed to form theplanets, satellites, asteroids, comets, etc.
Formation Of Atmosphere:
It is thought that Earth began as a cold world, and the very first atmosphere may have been hydrogen gas, but since that is so light weight and very chemically reactive, most of it would have floated off into space or reacted with other substances, thus would have been rapidly dissipated. Then some other volcanic activities and other chemical reaction took place.The inner four, solid planets have started out with similar atmospheres of H2O, CO2, CO, and N2. These chemicals made up the atmosphere of our planet for the first 1 billion years, and initially, provided similar atmospheres for the other three solid planets.However, the distance of each of these planets from the sun has influenced what subsequently took place there:
- Mercury is too close to the sun and too hot. Any water that might have been there (and any other volatile chemicals) would, long ago, have evaporated into space.
- Venus also is too close to the sun to have any surface water.
- Mars, on the other hand, is too far away from the sun, and so is too cold. Any water and carbon dioxide present on the planet are frozen solid in the “ice” cap. Also, the planet is too small to hold very much atmosphere, and there is not enough of a greenhouse effect to keep the planet warm. Thus, there is essentially no atmosphere left.
Formation of Earth Surface:
Over the next 3.5 billion years, the amount of CO2 in our atmosphere was reduced as it became incorporated into rocks (limestone is CaCO3 and forms when H2O + CO2 --> H2CO3and H2CO3 + Ca++ --> CaCO3 + 2H+). The liquid oceans formed about 3.8 billion years ago, and life has been present for nearly as long. Evidence would indicate that on early Earth, there was much more volcanic activity, many more electrical storms, and more violent and destructive meteor impacts. Because of this impact heating (and Earth’s internal heat) the Earth subsequently melted, and heavier molten materials sank to the center, forming the core, while lighter ones floated to surface and formed the crust. Thus Earth now has several layers:
- A central core composed of very dense metals such as iron and nickle
- The mantle, which actually consists of several layers of varying composition, and is a molten, medium density, viscous liquid
- The crust floats on the outside. Because the minerals in the crust are cooler, they have formed strong, rocky layers collectively referred to as the lithosphere.
The atmosphere was made largely of water vapor (H2O), carbon dioxide (CO2), carbon monoxide (CO), nitrogen (N2), methane (CH4), and ammonia (NH3). As the surface of Earth cooled again, torrential rains of this mixture formed the first seas, the “primordial soup.”
1. First, organic monomers (simple sugars, amino acids, fatty acids, and nucleotides) would have to be synthesized abiotically from inorganic substances like methane, carbon dioxide, and ammonia. Around all 20 amino acids, and a number of sugars, lipids, and nucleotides have been obtained from these inorganic substances(H2O, H2, CH4 and NH3).
2. The second step would be the formation of organic polymers and genetic material from the existing monomers (polysaccharides from simple sugars, proteins from amino acids, and RNA from nucleotides), possibly using hot sand or finely divided clay as a catalyst.
3. Thirdly, it is thought that non-living aggregates of these polymers formed. These may have exhibited some properties characteristic of living organisms, but were NOT ALIVE, and did not have all the properties of living organisms. In a research laboratory, scientists have seen mixtures of proteins, lipids, and carbohydrates form globules. If the proteins involved happen to be enzymes, these globules can even carry on "metabolic" activity, although they have no means to replicate themselves. Several widely-accepted theories as to how this may have happened include the possibly involvement of damp, zinc-containing clay as a catalyst to help the nucleotides polymerize first into RNA, and later into DNA.
4. It is thought, then, that about 4.1 to 3.5 billion years ago, the first prokaryotes, like bacteria, came into existance. It is difficult to pinpoint a date for this because bacteria don't have skeletons to leave behind. The first “fossils” (remains of colonies/secretions) of prokaryotes seem to be this age. Once the first cells, the first living organisms, the first prokaryotes came into existance, then the Theory of Evolution takes over to provide an explanation for how (not why) these primitive cells diversified into the five kingdoms of life which we recognize today.
Initially, the energy needed for growth and development was supplied by glycolysis and fermentation. There was no free oxygen in the early atmosphere, and indeed, any organisms living back then would have probably been poisoned/killed by this highly-reactive chemical. Only later, as photosynthetic organisms released increasing amounts of this toxic waste into the atmosphere, did the process of cellular respiration evolve as a means of making use of this oxygen.
Leaning Tower of Pisa
Friday, October 16, 2009
The Leaning Tower of Pisa (Italian: Torre pendente di Pisa) or simply The Tower of Pisa (La Torre di Pisa) is the campanile, or freestanding bell tower, of the cathedral of the Italian city of Pisa. It is situated behind the Cathedral and is the third oldest structure in Pisa's Cathedral Square.
The height of the tower is 55.86 m (183.27 ft) from the ground on the lowest side and 56.70 m (186.02 ft) on the highest side. The width of the walls at the base is 4.09 m (13.42 ft) and at the top 2.48 m (8.14 ft). Its weight is estimated at 14,500 metric tons (16,000 short tons). The tower has 296 or 294 steps; the seventh floor has two fewer steps on the north-facing staircase. Prior to restoration work performed between 1990 and 2001, the tower leaned at an angle of 5.5 degrees, but the tower now leans at about 3.99 degrees.
Leaning Tower Construction History:
The Tower of Pisa was a work of art, performed in three stages over a period of about 177 years. Construction of the first floor of the white marble campanile began on August 9, 1173, a period of military success and prosperity. This first floor is a blind arcade articulated by engaged columns with classical Corinthian capitals.
The tower began to sink after construction had progressed to the third floor in 1178. This was due to a mere three-meter foundation, set in weak, unstable subsoil, a design that was flawed from the beginning. Construction was subsequently halted for almost a century, because the Pisans were almost continually engaged in battles with Genoa, Lucca and Florence. This allowed time for the underlying soil to settle. Otherwise, the tower would almost certainly have toppled. In 1198, clocks were temporarily installed on the third floor of the unfinished construction.

In 1272, construction resumed under Giovanni di Simone, architect of the Camposanto. In an effort to compensate for the tilt, the engineers built upper floors with one side taller than the other. This made the tower begin to lean in the other direction. Because of this, the tower is actually curved. Construction was halted again in 1284, when the Pisans were defeated by the Genoans in the Battle of Meloria.
The seventh floor was completed in 1319. The bell-chamber was not finally added until 1372. It was built by Tommaso di Andrea Pisano, who succeeded in harmonizing the Gothic elements of the bell-chamber with the Romanesque style of the tower. There are seven bells, one for each note of the musical major scale. The largest one was installed in 1655.

After a phase (1990-2001) of structural strengthening, the tower is currently undergoing gradual surface restoration, in order to repair visual damage, mostly corrosion and blackening. These are particularly strong due to the tower's age and to its particular exposure to wind and rain.

Bermuda Triangle - Devil's Triangle
Tuesday, October 13, 2009
The Bermuda Triangle, also known as the Devil's Triangle, is a region in the western part of the North Atlantic Ocean in which a number of aircraft and surface vessels are alleged to have mysteriously disappeared and cannot be explained as human error, piracy, equipment failure, ornatural disasters. Popular culture has attributed some of these disappearances to the paranormal, a suspension of the laws of physics, or activity by extraterrestrial beings..The Bermuda Triangle is inexorably associated with time travel, UFOs, missing time and wormholes. Credible witnesses to the effects of the Bermuda Triangle have been witnessed by Charles Lindbergh to Christopher Columbus. When Charles Lindbergh was making a nonstop flight from Havana to St. Louis his magnetic compass started rotating. His Earth-inductor-compass needle jumped back and forth erratically. This has now all been revealed in his autobiography. Even a great pilot like Charles Lindbergh witnessed unusual events while flying in the reaches of the Bermuda Triangle.
Area Of Triangle:
Area Of Triangle:
The area is one of the most heavily-sailed shipping lanes in the world, with ships crossing through it daily for ports in the Americas, Europe, and the Caribbean Islands. Cruise ships are also plentiful, and pleasure craft regularly go back and forth between Florida and the islands. It is also a heavily flown route for commercial and private aircraft heading towards Florida, the Caribbean, and South America from points north.
Bermuda Triangle Major Events- Flight 19 was the first incident that was heavily reported on, bringing the Bermuda Triangle into the spotlight and under speculation. In 1945, Flight 19, a small aircraft containing 5 U.S. Navy bombers set out over the sea on a training mission. The plane was being flown by an experienced pilot, and for reasons unknown to this day, just vanished. Neither the plane, nor the crew aboard was ever found.
- As eerie as Flight 19's disappearance was, it was just a prelude to whatever happened to a Douglas DC-3 aircraft that disappeared without a trace over the Atlantic on December 28, 1948. The aircraft vanished without a trace sometime during its flight from Puerto Rico to Miami. Inexplicably, no wreckage, or any of the 32 people onboard were ever found.
- These disappearances sparked an interest in what some were calling the Devil's Triangle.
- Research on the area also pointed to the biggest loss of life that the U.S. Navy suffered that wasn't related to combat. On March 4, 1918, The USS Cyclops and its crew of 309 vanished without a trace sometime after leaving Barbados, an island in the Caribbean. Though many theories suggest everything from bad weather to an enemy attack, nothing has ever been proven to explain this mysterious disappearance.
Bermuda Triangle Theories:
Researchers and scientists have developed a host of theories to explain the mystery of the Bermuda Triangle. Many point to irregular and infrequent weather patterns, the Gulf Stream or rogue waves that crop up over the ocean and are difficult to predict. Other theories indicate man as the cause of the disappearances, suggesting error in reading compasses or flight tools, or even acts of violence such as piracy.
As theories may point to a natural or explainable reason for the mysteries in the Bermuda Triangle, there are other theories that point to phenomena that cannot be easily explained. Many believe that the Bermuda Triangle sits over the spot of the lost city of Atlantis. Another supernatural theory is that UFOs frequent the area over the Bermuda Triangle, and that the victims of these vanishings have been abducted by aliens.

Gate Tower: Highway Through The Building - Japan
Thursday, September 24, 2009
''Gate Tower'' is one of the wonderful buildings in Osaka. The Place of crossing High way and High rise.In Osaka, Japan’s “second city” , space for offices is severely limited. So limited that the 16 story ‘Gate Tower Building’ had to lose the 5th, 6th and 7th floors to a high way.The elevator passes through the floors without stopping. The floors through which the highway passes consist primarily of elevators, stairways and similar things without stopping and also it has heliport on roof.
The company building deteriorated and owners decided to reconstruct in 1983 also it has been decided which a highway passes due to city at the same time. Negotiation between owners and Osaka highway public corporation was taken approximately 5 years and at the end it did by the fact that Highway passes through the building.
Portion of road method, city planning method, urban renewal method and construction standard method was amended in 1989. The ''Gate tower'' is the first building which utilizes the three-dimensional road system in Japan.
Ten Weirdest Things in Space
Wednesday, September 23, 2009
The more we look among the star and galaxies, the weird things seem to get. Even space itself is puzzling, for example. Recent studies suggest that the fabric of the universe stretches more than 150 billion light years across--in spite of the fact that the cosmos is 13.7 billion years old. From super-fast starts to the nature of matter, here we cover other starnge and mysterious elements of the universe.
1. Hypervelocity Stars
If you've ever gazed at the night sky, you've probably wished upon a shooting star (which are really meteors).
But shooting stars do exist, and they're as rare as one in 100 million. In 2005, astronomers discovered the first "hypervelocity" star careening out of a galaxy at nearly 530 miles per second (10 times faster than ordinary star movement). We have ideas about what flings these rare stars into deep space, but aren't certain; anything from off-kilter supernova explosions to supermassive black holes might be responsible.
2. Black Holes
Speaking of black holes, what could be stranger?
Beyond a black hole's gravitational border -- or event horizon -- neither matter nor light can escape. Astrophysicists think dying stars about three to 20 times the mass of the sun can form these strange objects. At the center of galaxies, black holes about 10,000 to 18 billion times heavier than the sun are thought to exist, enlarged by gobbling up gas, dust, stars and small black holes. What about mid-sized types? Perhaps surprisingly, evidence is both scarce and questionable for their existence.
3. Magnetars
The sun spins about once every 25 days, gradually deforming its magnetic field. Well, imagine a heavier than the sun collapsing into a wad of matter just a dozen miles in diameter.dying star Like a spinning ballerina pulling his or her arms inward, this change in size spins the neutron star -- and its magnetic field -- out of control. Calculations show these objects possess temporary magnetic fields about one million billion times stronger than the Earth's. That's powerful enough to destroy your credit card from hundreds of thousands of miles away, and deform atoms into ultra-thin cylinders.
4. Neutrinos
Pull out a dime from your pocket and hold it up for a second... guess what? About 150 billion tiny, nearly massless particles called neutrinos just passed through it as though it didn't even exist. Scientists have found that they originate in stars (living or exploding), nuclear material and from the Big Bang. The elementary particles come in three "flavors" and, stranger still, seem to disappear on a whim. Because neutrinos occasionally do interact with "normal" matter such as water and mineral oil, scientists hope they can use them as a revolutionary telescope to see beyond parts of the universe obscured by dust and gas.
5. Dark Matter
If you put all of the energy and matter of the cosmos into a pie and divvy it up, the result is shocking. All of the galaxies, stars, planets, comets, asteroids, dust, gas and particles account for just 4 percent of the known universe. Most of what we call "matter" -- about 23 percent of the universe -- is invisible to human eyes and instruments.
For now, Scientists can see dark matter's gravitational tug on stars and galaxies, but are searching feverishly for ways to detect it first-hand. They think particles similar to neutrinos yet far more massive could be the mysterious, unseen stuff.
6. Dark Energy
What really has everyone on the planet confused -- including scientists -- is dark energy. To continue with the pie analogy, dark energy is a Garfield-sized portion at 73 percent of the known universe. It seems to pervade all of space and push galaxies farther and farther away from one another at increasingly faster speeds. Some cosmologists think this expansion will leave the Milky Way galaxy as an "island universe" in a few trillion years with no other galaxies visible.
Others think the rate of expansion will become so great that it will result in a "Big Rip." In this scenario, the force of dark energy overcomes gravity to disassemble stars and planets, the forces keeping particles sticking together, the molecules in those particles, and eventually the atoms and subatomic particles. Thankfully, humankind probably won't be around to witness to cataclysm.
7. Planets
It might sound strange because we live on one, but planets are some of the more mysterious members of the universe. So far, no theory can fully explain how disks of gas and dust around stars form planets -- particularly rocky ones. Not making matters easier is the fact that most of a planet is concealed beneath its surface. Advanced gadgetry can offer clues of what lies beneath, but we have heavily explored only a few planets in the solar system.
8. Gravity
The force that helps stars ignite, planets stay together and objects orbit is one of the most pervasive yet weakest in the cosmos. Scientists have fine-tuned just about every equation and model to describe and predict gravity, yet its source within matter remains a complete and utter mystery.
Some think infinitesimal particles called gravitons exude the force in all matter, but whether or not they could ever be detected is questionable. Still, a massive hunt is on for major shake-ups in the universe called gravitational waves. If detected (perhaps from a merger of black holes), Albert Einstein's concept that the universe has a "fabric" of spacetime would be on solid ground.
9. Life
Matter and energy abound in the universe, but only in a few places is the roll of the cosmic dice perfect enough to result in life. The basic ingredients and conditions necessary for this strange phenomenon are better understood than ever before, thanks to abundant access to life here on Earth. But the exact recipe -- or recipes -- to go from the basic elements of carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur to an organism is a prevailing mystery. Scientists seek out new areas in the solar system where life could have thrived (or still may, such as below the surface of watery moons), in hopes of arriving at a compelling theory for life's origins.
10. The Universe
The source of energy, matter and the universe itself is the ultimate mystery of, well, the universe. Based on a widespread afterglow called the cosmic microwave background (and other evidence), scientists think that the cosmos formed from a "Big Bang" -- an incomprehensible expansion of energy from an ultra-hot, ultra-dense state. Describing time before the event, however, may be impossible.
Still, atom smasher searches for particles that formed shortly after the Big Bang could shed new light on the universe's mysterious existence -- and make it a bit less strange than it is today.
