10 The Most Vicious Dinosaurs in Prehistoric Times

All stunned when witnessing and being part of the tension on while watching movies or TV shows such as 'Jurassic Park', 'The Land Before Time' or 'Walking With Dinosaurs'.

Ever dreamed But when giant creatures like the movie is still alive today.

How awful when we have to live with feelings of anxiety because it must always be vigilant, lest they stalking us and ready to attack.

Luckily this time they just become extinct prehistoric creatures, but discuss these giant animals remain attractive. Like making a list of 10 prehistoric predators of the most frightening, as shown below :

1. Madtsoia 

Madtsoia the giant snake, about 15-20 meters in length. How to kill their prey with large snakes in general, twisting and crushing the bones of its prey to death. This predator had become ruler of reptiles for a very long time, until finally disappeared 45 million years ago.

2. Dunkleosteus 
  
Dunkleosteus is a prehistoric fish that lived about 380 million years ago, regarded as the greatest sea creatures in his time.

With up to 10 meters long, weighing about 3.5 tons, armed with strong jaws, which may be biting objects with metal ones. The Dunkleosteus eat everything that is the sea, even the smaller members of their own species.

3. Sea Scorpion
 
Although his name is known as 'sea scorpion', but its the fact they do not live at sea. His name is officially called the Eurypterid. Its peak at 3 meters long over and eventually became extinct about 250 million years ago.

4. Argentavis
Argentavis is the largest bird ever found. Argentavis can literally translates to "bird Argentina extraordinary". Perhaps because the South American section of predators live.

Physical form almost like a bird glider, much like the Condor bird today, but with a cruising speed much better.

5. Terror Bird



   
Included in the family Phorusrhacidae (species of carnivorous birds that fly into the dominant predators in South America). But Terror bird can not fly, he can only run so fast to catch prey.

Terror bird has the head with a length of one meter and half like an eagle with a large size, giving the possibility to swallow seeokor horse with great ease.

6. Megalania

Megalania is a giant lizard with a size seven feet in length and has a toxic weapon in his teeth are very sharp.

Even though it looks scary and deadly, but Megalania a game for men ancient times, about 40,000 years ago. The remaining current is the smallest of its Megalania, namely Komodo.

7. Therizinosaurus

Therizinosaurus is not a predator, a very large physical form remains a record in itself. When first discovered fossils in the 1950s, an estimated Therizinosaurus is a reptile that resembles a giant tortoise. Although it is unclear that Therizinosaurus are herbivores.

Therizinosaurus has a small skull on a long neck and three-meter-long claws on both front feet. Claws has the function to fight to defend its territory or mating and to achieve a leafy tree branches.

8. Predator X
 
Predator X is the name that has not been authorized for marine predator that is claimed to be "the scariest animals in the ocean."

Has a body length up to 15 meters, weight 45 000 kg and 30 centimeters long with teeth (his teeth even more powerful than Tyrannosaurus), making a bite 10 times stronger than the current predator and four times more powerful than Tyrannosaurus.

There is one more fact that makes this a scary creature, Predator X only uses its two fins to swim, the other two may serve to capture prey.

9. Liopleurodon
 
Such as the Predator X, including the family Pliosaur Liopleurodon (marine reptiles from the Jurassic and Cretaceous Periods). Liopleurodon is also a carnivorous marine reptile that has a very large size, with a body length of 1.5 to 10 meters.

This giant has four legs resembling a large and powerful paddle, making it a good swimmer with exceptional speed.

Liopleurodon regarded as the ruler of the sea in the era of the early Jurassic and Cretaceous because of excluding the largest predator of its time.

10. Tyrannosaurus Rex

Predators are very popular because of her figure is often used as the main predators in the famous films dinasaurus world. Has the structure of the skull are large, heavy tails and two strong claws on each of his legs is the best known feature of any prehistoric monster.

Tyrannosaurus estimated length of 13 meters high and up to 4 meters and weigh 7000 pounds, making it the largest predator in its environment, hunt almost anything that can eat.

Some experts say that Tyrannosaurus was not but scavenger carnivores (birds of prey). This is a long debate in the world of paleontology.

7 PLACE ON EARTH ARE LIKE IN ANOTHER PLANET

If all this the travelers to spend hundreds thousands dolarAS (U.S. $) to enjoy a trip around the world, now try to do a trip to the extraordinary objects like surf like no other between galaxies but still stepping on planet earth. Mengunjungisalah an incredible place, you feel trapped another planet. The following 7 Place On Earth The Feeling On Another Planet, namely:

1. Blue Lagoon, Iceland

Blue Lagoon

This place is filled with many artificial ponds containing materialdari volcanic activity. With mineral-rich water contained herein is believed to have the power to cure certain diseases. In winter, hot steam emerging from the pool surrounded by snow and ice, thus creating a tense atmosphere.

2. Haleakala, Hawaii

Haleakala

Haleakala, the volcano is around Maui, Hawaii. Sabantahun almost more than 1.5 million people visit Haleakala. They sometimes just want to watch the sun rise or set, with a charm that is very dramatic, also saw a large crater at Haleakala cluster. The name comes from Hawaiiyang Haleakala means house of the sun. According to legend, the demigod of Maui has kept the sun in this place to extend the time of day.

3. Chocolate Hills, Philippines

Chocolate Hills

Limestone hill Choclolate Hills area of ​​20 square miles located island collapse, the Philippines, which covered nearly 1300 grass. These limestone hills altitude of about 100 to 400 feet. When the dry season, this mountain resembles a giant chocolate chip. Based on local legend, this hill is formed of a giant buffalo dung fed poisoned by local farmers. However, the scientists concluded that the hill was formed by volcano debris.

4. Craters of the Moon National Park

Craters of the Moon National Park

Craters of the Moon National Park in Idaho, an area that resembles a month you can be found in the United States. Formed from the volcanic eruption that occurred 15,000 years ago, creating lava field covering an area over 600 square miles. Last eruption created the power of coal and inlet cone-shaped lava.

5. Racetrack Playa, California

Racetrack Playa

Racetrack Playa in Death Valley National Park, California USA, now known as the mysterious rock slide (Moving Rock). This dry lake paved with stones and mud sediment. No one has ever seen the rocks move. But, the theory states that the movement is growing due to strong winds and due to the glacial ice. Impact occurs during the rainy season, shallow lakes where the surface becomes slippery.

6. Cappadocia, Turkey

Cappadocia

Cappadocia in Turkey featuring the unique rock formations called "fairy chimneys up". Cappadocia is formed from geological and volcanic activity, including weather and erosion, which occurred about 60 jutatahun Islam. Year 2000, the Christians built the first church was a unique area of ​​the rocks.

7. Dead Sea, the Middle East

Dead Sea,

Shores of the sea with salt water, called the Dead Sea is the lowest on earth, which is nearly 1,400 feet below sea level. The water here is saltier than ocean water, due to high salt levels, allowing a living creature can float on water. Dead Sea waters widely used for medical therapy. This giant lake water continued to shrink, because there are dangerous holes.

7 The Mystery of Planet Mars

Mars is known as the "star of fire" by ancient Chinese astronomers. Contemporary researchers often refer to it as the red planet.Although dozens of spacecraft have been sent to Mars, there are still many things that puzzle and raises questions about the planet. Here are some interesting mysteries of Mars listened to, along with NASA plans launch bicycle, Mars Science Laboratory Curiosity, over there on 25 November.

1. Why does Mars have two different faces? 
The researchers since long wondered why the two sides of the planet Mars has a striking difference? Northern hemisphere of Mars can be said to be flat and low land, even including one of the most flat surfaces, the most refined in the solar system. Conditions were probably formed by water that once flowed on the surface of the suspected red planet.

Meanwhile, in contrast, the southern hemisphere of Mars has a rugged surface, has a crater, and about 4 km to 8 km higher than the northern hemisphere. Recent evidence raises expectations that the difference between north and south sides of Mars was caused by a giant rock from space that hit Mars in the past.

2. Where the origin of methane on Mars?
 Methane, the simplest organic molecule, first discovered in the atmosphere of Mars by the Mars Express spacecraft European Space Agency in 2003. On Earth, most methane in the atmosphere produced by living things. Methane is thought to already exist in the Martian atmosphere 300 years ago. That is, whatever the source, where gas is not long.

However, methane gas may also arise out of life, such as from volcanic activity. ESA's ExoMars spacecraft will be launched in 2016 will examine the chemical composition of the Martian atmosphere and studied the presence of methane in there.

3. Where is the sea of ​​Mars? 
Many missions to Mars have found evidence that the planet once had conditions warm enough so that water does not freeze and can flow on its surface. Evidence that among other areas such as the former sea, valley networks, river deltas, and trace minerals that are formed as by water.

Even so, Mars climate models can not explain how the warm temperatures that could happen, given the much weaker sunlight first. There are allegations, the above forms are formed not by water but by the wind or other mechanisms. But still there is evidence that Mars was once warm enough to support the existence of liquid water, at least in one place on its surface.

4. Is there water on Mars today?
Although most evidence suggests that water once flowed on the surface of Mars, is still a puzzle whether there is water flowing over the surface of the planet at this time. Atmospheric pressure of Mars is too low, about one-hundredth the pressure on the Earth so hard to be in surface water. But there are dark and narrow path on the slopes of Mars that raises a presumption that there is water that flows each spring.

5. Is there life on Mars? 
The first spacecraft to successfully land on Mars, NASA's Viking 1, gave rise to a puzzle that remains mysterious at this time: Is there any evidence of life on Mars? Viking is a vehicle that is specifically assigned to look for life on Mars, and what is found is still being debated to this day. The spacecraft has discovered the existence of organic molecules such as methyl chloride dandichloromethane. However, these compounds could be the contamination of the Earth is getting carried away when the vehicle slid on Earth.

The surface of Mars itself is not hostile to living things in terms of very low temperatures, radiation, dry conditions, and other factors. Even so, there are living creatures that can survive in extreme environments on Earth, such as the Dry Valleys of Antarctica is cold and dry, or very dry region in the Atacama Desert in Chile.

In theory, there is always life, as there is liquid water on Earth. The possibility of the existence of oceans on Mars ever raised the question of whether life ever existed there. If there is, whether today's living creatures still exist? The answer to that question may help shed some light on the question of how common is life in the universe.

6. Is life on Earth came from Mars?
 Meteorites found in Antarctica and are from Mars, was thrown from the red planet from collisions of cosmic-rock has a structure similar to that produced microbes on Earth. Although further research showed that the structure was formed due to chemical rather than biological processes, the debate on Mars as the origin of life on Earth continues. Some people still hold the theory that life on Earth came from Mars, and brought to Earth with meteorites.

7. Can humans live on Mars? 
To answer whether life ever existed or still exist on Mars, humans may need to go there and look for yourself.

In 1969, NASA had planned manned mission to Mars in 1981 and establish a permanent station there in 1988. But it turned out to interplanetary travel of scientific and technological challenges are not small.

The scientists had to overcome a variety of interplanetary travel problems, such as food, water, oxygen, the effects of micro gravity, the possibility of harmful radiation, and the fact that the astronauts who go there will be millions of miles from Earth so it is not easy to get help if anything happens. In addition, land, work, and life on other planets and then return to Earth was not easy.Even so, many researchers who want to do that mission. This year, six volunteers live in isolation as was in the spacecraft for 520 days in the project, called Mars500. Longest space flight simulation is intended to mimic the journey to Mars.

Many volunteers are willing to fly to Mars even though the possibility can not kembali.Berbagai plan was also created, for example by sending the first rock-eating microbes, before humans were imported. The puzzle about whether humans will ever set foot on Mars is still dependent on the reason, why we should try to explore the red planet

8 Unique Place Arround The World

1. Mount Roraima, Venezuela, Brazil and Guyan Mount Roraima is a place of incredible scenic beauty. The rock is unique because it is like the hood of a table that is in the cloud. Height of 400 meters. One other way to reach the top of the roof that is to climb up the table line the stairs which was already provided Venezuela's Government. Another way that is not recommended is wont to do the rock climbers. There it rained down almost every day, washed away crops vines located on the roof. The result, the roof of the mountain to be unique, because it is clean of any ...aliases such as ' empty ' table.


2. The Guaíra Falls, Brazil-Paraguay border most people consider Niagara Falls are the largest in the world. Guaira Falls is actually the world's largest waterfall by volume achieved an average of 1,750,000 cubic feet per second. Compare with Niagara Falls are only 70,000 cubic feet per second. Source of Guaira Falls in Brazil-Paraguay, perbatasasn is the River Parana. In 1982, in ternjun water dam was constructed to Guaira power plant under the name of Itaipu Dam which is now the second largest dam the world's largest producer of electricity after Gorges Dam. Itaipu Dam supplies 90 percent of electricity to Paraguay, and 19 percent to Brazil, Rio de Janeiro and Sao Paulo.


3. Iceberg B-15, the Antarctic iceberg B-15 is the biggest iceberg recorded in history. It has reached 3,100 miles, making it bigger than in the past, Jamaica. A giant iceberg this occurs due to the Ross Ice Shelf in March 2000. Then in 2003, the iceberg B-15 was again split into several pieces, one of which the largest are called B-15a drifted northward, eventually falling into glacier in 2005, leaving the ridge along the 8 km. This makes big changes happen on a map of Antarctica and demanding to be revised (map).

Some drifted to the coast eventually was wrecked. In 2006, a hurricane in Alaska, menyebbakan ocean wave crossing to 13,500 miles over the course of 6 days to Antarctica, and the rest into separate fractions and more. Almost a decade passed, those parts of the iceberg that is still not entirely liquid, part of the biggest are still regarded as B-15a, with vast fields reached 1,700 km. picture above is called iceberg B-15a, after drifting into the Drygalski Glacier (bottom), his final break up into several pieces.

4. Don Juan Pond, Antarctica's most high Place which deposits salts? Surely people will refer to the dead sea. The dead sea is famous in the world due to the salts are very high. Based on research, high-salt sea water it could be a health therapy. It's no wonder that around the dead sea spa-spa constructed for therapy, particularly health and beauty therapies. But it is not the terasin of the dead sea in the world. It is precisely in the Antarctic lah, Don Juan Pond, a lake with the highest salt content in the world.

The comparison if juxtaposed with the sea in General, Don Juan Pond 18 times saltier than sea water, when compared to the dead sea, Don Juan Pond 8 times more salty.
The location was discovered by Lt Don Roe and Lt John Hickey, in 1961, when both conduct research in Antarctica. The name of Don Juan Pond is also given by the two researchers, soldiers may be merging both names. The temperature in the pool is generally in the region-such as the Antarctic, is fairly low, with the lowest point can reach-30 Celsius drajat. But never make it freezes like elsewhere in Antarctica.

5. New Zealand Rotorua, Rotorua is a city on the edge of the Sea South of the Lake of the same name. In the Bay of Plenty, North Island of New Zealand. Uniqueness of the region is the large number of pools, hot springs Geyser at Whakarewarewa in particular Pohutu, boiling mud and mud. The area was a unique and interesting so that many travellers.


6.83-42, Weird and unique. Greenland But 83-42 believed it is the only land that is in the northern part. It's just a DAB of ' size ' approximately 35 m x 15 m and a height of 4 m. Judging from above, like a speck of land that is surrounded by only fractions of ice. Unique! When the North Pole is covered by ice, but the ground is not. Look at the picture! This uniqueness and subvert the previous record which ATOW 1996. The uniqueness of the 83-42 was discovered in 1998.


7. The Republic of Yemen, Socotra Socotra strangest places at once the most unique in the world. Almost everything in there looks odd, ranging from tree shape as well as its surroundings, it's no wonder many who call Socotra in the Republic of Yemen as one of the alien's Lair in the world. The place is very isolated, arid climates other than others. This could be causing bizarre plant life as well as any objects there grew up with strange. Call it the plant such as Dragon's Blood Tree, its shape is very uncommon, it looks like paying. This tree produces red-colored SAP. There also exist animals original, like birds, spiders and other native animals. Not to mention, the rocks also form reefs is not common and there is only on the island. With all the contents of the island's peculiarities, it's no wonder that Socotra, an island located in the Arabian Sea, entered into the legacy of World Heritage.
 

8. The Door To Hell, Turkmenistan may have it all figured out, at least have read or seen the news of his pictures. It's no wonder because of this nature in Turkmenistan fenomen somewhat unique. People call it ' the doors of hell "because in the crater 70 meters wide was out the api that continuously since last 35 years. Starting from the year 1971 in which the geologist member area to look for mine gas. That ensues is a burst of fire from the ground that continuously, even had a chance to swallow all their equipment. The geologist was nobody dared to go down into the poisonous. You can see it on Google Earth at 40 ° 15′29″e/33.8 ° N 44 ° e/26.23.

History of The Number Zero "0"

Do not underestimate the number zero. Imagine, what would happen if the sequence of numbers there are only nine numbers (1,2,3,4,5,6,7,8, and 9) without the zero? Of course problems will arise, for example, which show the number of tens, hundreds, thousands, millions, or tens of millions?Well, in the presence of zero, all problems were solved trapped. Thanks to zero, arithmetically become increasingly widespread and function properly.

In addition to the essential function, the zeros also have a long history. Where does the actual numbers come from? And who are its inventors? Perhaps many thought, scientist inventor Europeans. Indeed, the zeros would be found by Muslim scientists. He is Abu Ja'far Muhammad ibn Musa al-Khwarizmi. He was born in Khwarizmi (now Khiva), Uzbekistan, in 194 H/780 AD

Not much information is explained in depth about the figure and life history of Al-Khwarizmi. However, there is a brief history of the book of Ibn al-Fihrist an-Nadim, which also explains the works he wrote.

It says, Al-Khwarizmi to her almost all his work between the years 813-833 ga hing. After Islam came to Persia and Baghdad became the center of science and trade, many traders and scientists from China and India come to the city, including Al-Khwarizmi.

There, he became part of the scientists who worked at the Bayt al-Hikmah (House of Wisdom), a research and development of science that was founded by Ma'mun ar-Rashid, the Abbasid caliph seventh. By the professor of Islamic studies at Temple University United States, Mahmoud Ayoub, Bayt al-Hikmah referred to as the first institution of higher education in the Islamic world and the West. In this institution, Al-Khwarizmi studied the natural sciences and mathematics, as well as translation of the Sanskrit and Greek manuscripts.

Long ago, before Al-Khwarizmi introduced the zero, the scientists used a kind of list that distinguishes units, tens, hundreds, thousands, and so on it. List known as the abacus is working to keep each number in numbers not to be confused with each other from their place or position in a matter.

They apply to the 12th century AD, when Western scientists began to choose to use al-binji raqm (Arabic numerals) in their number system. Raqm albinji use the number "zero" is adopted from India figures, to present his decimal numbering system that has not been used before.Now, through his first book, Al-Mukhtasar fi al-Jabr wa reckoning al-muqabalah (Summary and Comparison of Algebraic Computation), Al-Kha ka ang warizmi introduce zero in Arabic called shifr. It also discusses the monumental work of the systematic solution of linear and quadratic notation.The book was translated in London in 1831 by English mathematician, Fredrick Rosen, and then edited in Arabic in 1939 by two mathematicians of Egypt, Ali Mustafa and Muhammad Mursi Ahmad Musyarrafa. Previously, pa da 12th century, work was also mentioned as translated by the mate matikawan from Chester, England, Robert (Latin: Robertus Castrensis), under the title Liber-mucabola Algebras et al.

Still in the same century, Latin-language book was later edited by mathematicians from New York, LC Karpinski. To both versions, De Jebra et Almucabola, written by Gerard da Cremona (1114-1187), mathematician and translator of Italian origin. The book was written by Gerard touted better and even surpass Rozen Fredrick book.

Thus, although the first has been introduced in the mid-ninth century, new zeros are known and used by Western scientists two and a half centuries later. Following the introduction of the zero by Al-Khwarizmi is the first zero is used as a place holder in a position-based notation. The world needs to thank the scientists on this one because with the introduction of zeros, numbers 2012 and 212 can be distinguished.

In the 12th century, the Muslim Council of Spanish mathematics, Meir ibn Ibrahim ibn Ezra, wrote three treatises on numbers which carry the symbols of India and decimal fractions to Europe up to get attention from a number of scientists there. The title of her treatise The Book of Numbers describes the decimal system for integers with place values ​​from left to right. Ibn Ezra uses zero as galgal (meaning wheel or circle).

Subsequently, in 1247, mathematician China, Ch'in Chiu-Shao wrote Mathematical Treaties in Nine Sections that use the symbol O for zero. And in 1303, Zhu Shijie use the same symbol for zero in his works Jade mirror of the Four Elements. Number system is further developed in Europe.Al-Khwarizmi, the scientist behind the discovery of the ma te matika the 9th century, the death in Baghdad in about 850 AD
