Niagara Falls Through the Ages

Niagara is a large waterfall on the Niagara River at the international boundary line between United States state of New York with the Canadian province of Ontario. This waterfall is about 17 miles (27 km) north northwest of Buffalo, New York and 75 miles (120 km) southeast of Toronto, Ontario.

Niagara is a group of three. The third waterfall is a waterfall Horseshoe (sometimes referred to as Canada's waterfall), waterfalls America, and the smaller Bridal Veil waterfall by an island which dipisahkn Luna Island from the main waterfall.

Although not too high, the Niagara waterfalls are very wide and most popular in the world. More than 6 million cubic feet (168 000 m3) of water per minute was dropped and this is the most powerful waterfall in North America.

Niagara Falls is renowned both for its beauty and as a valuable source of hydroelectric power. Manage the balance between recreational, commercial, and industrial uses has been a challenge for the servants who fall since the 1800s.

The peak number of visitors occur in the summertime, when Niagara Falls be an attraction both day and night. From the Canadian side, floodlights illuminate both sides of the waterfall for a few hours after dark (until midnight). Number of visitors in the year 2008 is expected to reach 20 million and in 2009, the annual rate is expected to top 28 million tourists a year. The oldest and most famous tourist attractions in Niagara Falls is the Maid of the cruise ship Mist, named for an ancient Indian myth Ongiara, which has been carrying passengers into the whirlpools beneath the Falls since 1846. Cruise ships operate from boat docks on both sides of the waterfall.

Really Niagara Falls Ever Really Frozen?

For mere information, Niagara Falls carrying 212 000 cubic feet of water for second. Average depth of the Niagara River is about 16 feet, with a flow speed of 6 to 8 miles per hour.

The answer, Niagara waterfall really is not a total freeze. Approximately 6 feet below the surface of water ice is still mengalir.sumber

But still, the phenomenon of frozen Niagara Falls into its own prima donna in the history of world science. Why not, the mighty waterfall that apparently never been defeated by the cold temperature of the world.

And still, the photographs found in the era before the second world war, became a rare authentic evidence, the eternal witness to the world how cold temperatures at that time.

Unique Facts:

Niagara Falls is not the largest in the world because it is actually still lose when compared to Victoria Falls waterfall in South Africa. When asked why more famous Niagara waterfalls waterfall than Victoria? Answer is simple enough: yes since Niagara is located in the United States. And one more thing to give evidence to us that the greatness of a country or nation will have implications on other things that actually large enough to "look like" the greatest.

Of the total discharge of the Niagara river water that can reach about 45 million gpm (10.2 billion liters / second), actually only a part of the total water that flows to form a waterfall. Yet still, after all the roar of Niagara Grojogan like to hit and swallow whatever is in front of him.

Niagara had proved to be swallowed desperate men. According to records, at least 16 people have been known to jump reckless with water using a wooden barrel or other equipment. Six of them died and ten others had survived. Two people who survived are listed Telson Annie Taylor in 1901 and earlier in the year 1829 Sam Patch, Sam Patch though eventually also died when it plunged in kenekatannya different waterfalls, Genesee Falls in Rochester.

In 1961, William Fitzgerald doing the same thing, and so came safely to the surface water directly led police and arrested because it was there a rule that prohibits acts of adventure around Niagara Falls.

Wina, City of the world's best

LONDON - The city is most comfortable in the world? Survey research and consulting firm Mercer called the City of Vienna in Austria as the best city to live.

Forbes was quoted as saying last Wednesday May 26, Vienna defeated another city after collecting the highest quality of life index, namely 108.6, and 126.2 index of environmentally friendly city. Predicate best city is the second time after the 2009 Vienna achieved then also awarded a known sama.Wina has produced great composers like Joseph Haydn, Franz Schubert, Johann Strauss considered hostile to life and business environment and also have a comprehensive public transport system.

Behind Vienna, the annual survey Worldwide Quality of Living Survey this year put the two cities in Switzerland, namely Zurich and Geneva, ranked second and third. Both the city collects each index of quality of life of 108 and 107.9. While eco-friendly city for the index respectively 133.5 and 131.1.

"Cities and towns in Switzerland is very pleasant with a clean natural environment. We consider the prevalence of Switzerland's neutrality, "said Rebecca Powers, a consultant Mercer.

"If you can not safely stay in Switzerland, you will not be safe anywhere," he added. Based on Mercer's survey, with the advantages of Vienna Zurich beat the index more than half a point and less than one point from the third position. These data show that the three major cities in the world index, which weighs almost the same.

"There may be little advantage compared to Switzerland and Austria to make us like hair splitting between the two countries," said Powers.

The fourth place until the 10th of each occupied Auckland (New Zealand), Vancouver (Canada), Dusseldorf (Germany), Munich (Germany), Frankfurt (Germany), Bern (Switzerland), and Sydney (Australia).

In Mercer's survey this time, cities in Europe occupies seven of the top 10 places for quality of life as it is considered relatively safe in political stability and cultural offerings. The cities in the United States (U.S.), Honolulu, known as the favorite for the best tour in the land of Uncle Sam was only ranked 31st on the list of Mercer.

Other U.S. cities such as San Francisco is at number 32, and Boston (37), Chicago and New York (49), while Philadelphia and Dallas for the first time this year on the list ranked the best city to-55 and 61. Ranking the best cities conducted Mercer overall placing 221 cities around the world based on evaluation of 39 factors from 10 categories.

The 10 categories are political conditions, economy, health, education, public services, recreation, availability of daily necessities, housing, and environment. From to-10 category, was split into several measurements such as public transport systems, law enforcement until the availability of restaurants and air pollution factors.

Cities must compete with the City of New York's index as a comparison city. New York's own index set with a score of 100 points. At this time the Mercer survey, the cities with the highest points are places that have the best safety records and low levels of political upheaval. Another factor that affects the rating is the existence of cultural facilities, infrastructure and availability of good schools.

Especially in the U.S., although kotakotanya excluding bad in the provision of public facilities, Mercer gave a note to the safety factor is considered to be weak, so unable to compete with Western Europe. "In the U.S., crime is usually more an issue of weapons umum.Ketersediaan sana.Banyak locations outside the United States such as Canada and Switzerland's social life is more clean because the number of crimes was minimal," added Power.

In Asia, Singapore was ranked highest as the best city in the world to live. The city-state is ranked 28th worldwide, while Tokyo at number of other 40.Kota in Japan, namely Kobe and Yokohama, also included in the top 50, then in a position to Osaka and Nagoya-51 in order to 57. As for the cities in other Asian ranks the most under the alias as the worst city. The town was referred to Dhaka, Bangladesh (206); Bishkek, Kyrgyzstan (209), and Dushanbe, Tajikistan (201).

Mercer senior researcher Slagin Parakatil disclose, adverse conditions in Asian cities is a concern because of increased threats of violence and terrorism, coupled with natural disasters such as earthquakes, typhoons, hurricanes.

"This resulted in an increased requirement for higher allowances for expatriates who are sent to these countries," added Paratakil.

Unfortunately Mercer did not mention where the position of Jakarta. This year also introduces the town of Mercer ranking criteria environmentally friendly (eco city). Cities are assessed by considering the quality of life, including how big a city to promote awareness of sustainability and protecting the environment. For the category of eco city, the City of Calgary in Canada at the top, followed by Honolulu and Minneapolis in the U.S..

Placement of environment-friendly cities are also seen based on the level of water quality, air, waste disposal, and traffic jams. "Many cities that ranked high for the quality of life and also a responsibility to ekologi.Ini probably because they are able to think about the environment," says Powers

World's lightest Soccer Shoes

Adidas launched its newest product in the world's lightest football boots "F50 adiZero". Shoes with a weight of 165 grams has a special design that is used to meet the demand of speed in playing soccer.

This lightweight shoe print was obtained from (shoe last) lightly equipped with a wider footbed and heel that can distribute power optimally. Microfibre raw materials derived from polyurethane which can reduce the overall weight and ensure that the shoe fit the foot, like a second skin.

"Officially launching adiZero F50 has been done since the beginning of March 2010, while for Indonesia, began marketing done per day," said Monica as Indonesian Adidas Brand Communication in a press conference in Jakarta on Monday (5/24/2010).

In a grand event for the 2010 World Cup in South Africa, F50 adiZero also be used by some famous players who was appointed ambassador of Adidas, such as Lionel Messi and David Villa.

'I was amazed to feel how the newest of the Adidas F50 light of this, even I almost did not feel like wearing shoes, "said Lionel Messi in the news release

Similar also disclosed former Valencia striker David Villa. "Speed is important when playing football. I'm really looking forward to the moment when I move faster while playing in South Africa later on against the world's best national team in a few weeks," Villa said in a press release.

David Villa will use the F50 adiZero black and white version, while Messi using a special version of chameleon color purple and white with electric accents.

It costs about $ 199

Qbot, Robot Mini that was funny and cute

Jakarta - Developer robots Spaniard, Francisco Paz created a mini robot that is funny and adorable. Robot Qbot named this could serve as a home robot that can be bought a lot of people.

Qbot was created without having your arms and legs. Although robots can not do this looks okay, but Qbot designed with some interesting features. One is designed to be interactive robots.

Qbot development based on open source software and hardware to upgrade DIY (Do It Yourself). With a height of 18 inches and weight 19-24 pounds, Qbot purposely designed for the consumer to be a mediocre marsupial can be enjoyed by many people.

Equipped with three wheels, this robot is claimed to be able to avoid obstacles. Plus four infrared sensors, ultrasonic, and her eyes stereoscopic vision and webcam to detect faces. Not to forget, three microphone to recognize voices and the LED to give a facial expression and speech synthesis to allow the speakers.

Quoted from Cnet, on Thursday (26/05/2010), Paz told in his blog that it took over five years to design Qbot. This project was inspired by a desire to create a home-based robotic pets like cats and dogs.

Quoted Tokyo University engineering professor, Tomomasa Sato, Paz meet its creators call a robot to begin creating a global standard open source robot which later became Ford's Model T or the consumer robotics.

Sato believes global standard robot is able to inspire tens of thousands of engineers around the world to realize the dream of having a personal robot that is useful at home.

Indonesian Batik So the World Heritage

Indonesia's struggle to gain world recognition for batik as an original Indonesian cultural heritage is not in vain. United Nations Educational, Scientific and Cultural Organization (UNESCO) will certainly reinforce the batik tradition as one of the world's original cultural heritage of Indonesia in the coming October in France.

Said by the Director General of Culture Value, Arts and Film Department of Culture and Tourism, Tjetjep Suparman in Surakarta, Tuesday (2 / 6). "It took three years to propose," he said. Previously, puppets and dagger also has received similar recognition from UNESCO some time ago.

"Six countries including representatives from UNESCO has conducted an assessment of batik culture," said Tjetjep. After doing the assessment and verification for three years, finally there is recognition to culture as the culture of Indonesian batik. "On 28 September 2009 stipulating tomorrow," said Tjetjep. While the new inaugural will be conducted on October 2, 2009 in France.

Besides batik current government has also filed several cultural products to gain the same recognition, including gamelan and angklung. "Hopefully the process will go well," he said.

Separately, Chairman of the Society Kampoeng Laweyan Batik Surakarta, Alfa Fabela particularly welcome the recognition. "We just hope that youth can to help preserve the cultural traditions of batik," said Alfa Fabela.

She also hopes the recognition can be made more known batik. 'As a result, exports could also increase, "says Alfa. Mekipun according to him, this time mostly batik makers still focus to work on the domestic market.

5th Largest Natural Disaster Ever Happened

Natural disasters are something that no one wants to experience it. This disaster is so deadly, for those affected either directly or indirectly. Here are five of the most widely claimed disaster casualties:

1.Central of China floods in 1931 (Flood of China Central):

Occurred in 1931, Central China Flood is said to be the deadliest natural disasters ever recorded. At that time, after a long dry China hit by seven hurricanes, which brought torrential rain brings. During the floods in central China, three other rivers join the river overflowed Yangzte, Yellow River and Huai River. Reported four million people died because of this flood.

2. Yellow River flood 1887

Yellow River, located in China is very vulnerable to flooding. In the Yellow River flood in 1887 caused the destruction of approximately 50,000 square miles of land. The farmers who live near the river actually has built a moat - a small moat to help hold water if the flood comes. But heavy rains that came too soon exceed the capacity of these small trenches. Flood said to have killed between 900 000 - 2,000,000 people.

3. Shaanxi Earthquake, 1556

Shaanxi earthquake which stands as the most deadly earthquake. On February 14, 1556, an earthquake hit China. Epicenter located in the Wei River Valley, as many as 97 villages of Henan, Shaanxi, Hebei, Anhui, and others affected. Statistical data shows 60% of population of 97 villages were killed. Overall, more than 830 000 people die from Shaanxi earthquake.

4. Bhola Stroms, 1970

Bhola storms hit East Pakistan, now known as Bangladesh on November 12 1970.Terkenal as the deadliest hurricane ever recorded. 115mph winds with the strength and reach hurricane strength of three categories. 500 000 people reportedly died of a storm at sea that brought heavy rain and caused flooding in many areas.

5. Indian Stroms, 1839

n 1839, a huge storm hit Coringa, India. This occurred on 25 November 1839 when a storm as high as 40 feet (12 M) destroyed the city. Unfortunately this city is not adequate infrastructure, 20 000 ships anchored in the town were destroyed. More than 300,000 people have died after the storm surge down.

Know Your Playstation Creator

Who does not know the Playstation (PS)? Console game graphics production Japanese electronics giant, Sony, was popular throughout the world. Behind it all, not many people know that a man named Ken Kutaragi to be the one most responsible for forming 'Playstation generation'.

Born in Tokyo on August 8, 1950, Kutaragi social circumstances pertained casual. They live by managing your own business, a printing factory in the factory town. Since childhood Kutaragi has developed mechanical skills at the plant, after school.

Kutaragi is known as a student smart. With intelligence like that, it's easy to get a job at Sony's Kutaragi, over the degree of electronics engineer. Kutaragi at the company's reputation soared. He is known as an exceptional problem solver. Projects that had always worked brilliantly handled, including the creation of liquid crystal project plays (LCDs) and digital camera.

His interest in creating a game console began in the late 1980s. One day, he watched his daughter playing a Famicom. Instinct kissing video games business potential. Unfortunately, while Sony executives were less interested. Kutaragi spirit which swelled to even create video games of one hand clapping.

However, Kutaragi creativity smelled Nintendo - game console company that is now the number one competitor Sony. When Nintendo asked him to create a chip, Kutaragi was powerless to refuse.

Secretly, Kutaragi worked for Nintendo's secret project. SPC700 chip designs. Unfortunately, the Sony smell it work. Kutaragi was almost fired, if the CEO of Sony. Norio Ohga, did not intervene. He even asked for Kutaragi's side complete the task.

Sony's Kutaragi continues to ask for a research fund making the Super NES CD - technology applied to the PS. When ambition is undoubtedly among eksukutif Sony, once again Norio Ohga support them. In 1990s, finally officially launched the Sony PS products.

Did not take long, the PlayStation soon brought many famous and money to Sony. Until May 18, 2004 only, Sony has produced 100 million PS. That success was also made president of Sony Computer Entertainment Kutaragi in 1997.

Brief Biography of Ken Kutaragi

Ken Kutaragi was born on August 8, 1950 in Tokyo Japan. As a child he was known as a diligent and smart, she is described as a disciple who was always getting the value 100. Kutaragi also known as a child who likes tinkering with things mechanical, he often opened his own toy and see how the toy works. From the nature of curiosity, finally took an interest in electronics to adults, on the grounds that he also studied and graduated from Denki Tsushin University majoring in electronics. After graduation he began working at Sony, where he got a good reputation as a solver of problems and succeeded in bringing success to Sony's projects that he followed (including the initial projects LCD and digital camera).

In the late '80s, a moment he saw his daughter playing Nintendo's Famicom, Ken Kutaragi realized the potential of video games. However, at that time the management of Sony was not interested in the Video Game industry. Nintendo chance and coincidence with the help of Sony's desire to create a wave-table sound chip for the SNES, Kutaragi immediately accepted. Though she had worked with Nintendo, Sony, which looked down on video games. However, Kutaragi may be funds to develop the Super NES console CD which eventually became his own besutan namely Sony PlayStation. Unsuspected even compete with Nintendo and SEGA are already seasoned in Video Game Industry, Sony's success with their console.

Ijen Crater is the Best Big And Beautiful World

Mount Ijen Crater is one tourist destination in East Java, which is always crowded visited both domestic and foreign tourists. Enjoying a beautiful natural mountains and cool they often do with the way camp at Paltuding.

Ijen Crater Lake is a lake located at the peak of Mount Ijen. Because the process of Ijen volcano, the crater filled with water to form a crater lake which is very beautiful and amazing.

Crater lake with green water toska and was very acidic pH. In the southeast of the lake there is solfatara field wall and crater lakes in the western part there is a crater Dam upstream from Banyupait time.

Mount Ijen solfatara field which is always releasing volcanic gases with high sulfur concentration and the smell of gas sometimes sting and irritate the respiratory tract is a tourist attraction that never missed to visit, even in the daytime this place never quiet because there is always the sulfur miners taking and transporting / carrying sublimat Paltuding sulfur reached.

Ijen Dam is part of interesting tourist attraction but not always visited by tourists due to among other accomplishments that are difficult due to the road to get there is often damaged due to landslides. Ijen Dam is concrete buildings built since the Dutch colonial era and are intended to regulate the lake water level so as not to cause flooding of acid water

But this dam is now not working because the water never reached the door due to water seepage / leakage of water under the dam lake.

The occurrence of this continuous seepage results in the process of formation of gypsum from sulfuric reaction products contained in the lake water with calcium compounds from the water and with calcium from the rock that is passed and the evaporation process is also accelerated its formation. Gypsum field can be one of the interesting tourist attraction when it is managed professionally.

Travel tours to the crater of Ijen, starting from Paltuding 1.600 masl, an outpost at the foot of Mount Merapi Perhutani-Ijen. From here a dirt road continues to climb to an altitude of 2.400 m above sea level with a travel time of 1.5 - 2 hour leisurely stroll. Along the way many bearers passed by exchanging friendly greetings sulfur.

Arrive at the crater lip, a green lake Tosca with a diameter of 1 km covered in mist and sulfur fumes were far below. For it could lead to source of sulfur TSB, had to descend through a rocky cliff caldera path traversed by the miners. Wet handkerchief is necessary, since often the wind blew the smoke toward the path carrying a decline.

Based crater, parallel to the surface of the lake there is a place-making sulfur. Thick white smoke gushed out from a kind of iron pipe which is connected to a source of sulfur. 600oC molten red hot fumaroles melt out and frozen with cold air, forming a bright yellow solid sulfur. Sometimes uncontrolled burning embers fumaroles, which are usually drenched with water immediately

to prevent a chain reaction piroporik. Sulfur rocks are cut with a crowbar and transported kedlm basket. The miners generally work with a bit of cloth or piece of cloth gloves as makeshift air filter.

Climbing to the crater of Ijen is generally recommended starting in the morning. For security reasons, climbing into the crater from Paltuding closed after 14:00, because the thick smoke and the possibility of wind direction that leads to a climbing lane.

When you travel in the morning, visitors are advised to stay at nearby locations such as Cottage Tours in Paltuding clean enough, or open the tent at the campground Paltuding. If you want to enjoy the atmosphere of the mountain plantation,

a memorable place to stay is the Coffee Plantation Guest House in Kalisat PTP Nusantara XII, Jampit. This guest house is located within the plantation housing complex at an altitude of approximately 1.200 masl. Temparature average around Ijen crater is 13 oC during the day and 2 oC at night. at the inn Paltuding.

U.S.A Scientists Create "Artificial Life"

VIVAnews - A team of scientists in the U.S.A admitted that succeeded in creating "artificial life" first in the world. This is a series of live bacteria cells generated artificial DNA based on computer programming.

Thus says Craig Venter, who led the research team at the J Craig Venter Institute in Rockville city, state of Maryland. "This is the first cell on this planet whose parents are computers," said Venter as contained in the pages of USA Today newspaper, Thursday afternoon May 20, 2010 local time.

"These cells originated from a digital code on a computer," said Venter, who is known as one of the pioneering researcher on the study of human genome mapping and synthetic biology.

This discovery is "a decisive moment in the history of biology and biotechnology." So said Mark Bedau, Reed College scholar and editor of the Journal "Artificial Life," as quoted by Science magazine.

Blue living bacterial cells were stored in a cooler and will be exhibited in a museum. The cell was believed to be not contagious. Venter Institute believes that the creation had a great impact for other studies.

"Through this study, the team has been involved in discussions and external ethical review and realize the social implications of this research," according to Venter Institute.

Venter is now planning to build a software (software) specifically for the development of that cell. The research team initially copying an existing bacterial genome and then assemble the genome of the genetic code and use "synthesis engine" to create a new copy of a chemical.

"We are now able to take a synthetic chromosome and transplanting into recipient cells, which is a different organism," said Venter told BBC television.

So, he continued that once the software they created to function, during the concerned will react and turn into the species which mapped the genetic code.

"It is the first fully synthetic DNA to control a cell," said Venter

10 Mistakes of Science We Get From School

There are some misunderstandings in the implementation of science in public that need to be corrected truth.

Here there are approximately 10 misconceptions about science that circulate in the community.

1. Water IS blue, not Just Because of the Sky

(Blue colored water caused not only a reflection of the sky)

Many believe that the lake and the blue sea "Only" because they reflect the blue sky. Actually, the water looks blue because they are really blue. Water molecules absorb light, and they absorb red frequencies more than the frequency of blue, so the frequency of blue appeared on the surface. Effect was small, so the color blue to be seen more clearly when observing layers of water or in dense enough. In salt water or mineral springs, mineral colors of decay can be seen.

Perefleksian color of the sky also provides a role for the blue ocean, but only when surface water is very calm and only when water was observed with a small kesudutan around 10 degrees.

2. Electricity does NOT travel at the speed of light

Many textbooks claim that the electricity (electrons) flow through the cable runs at the speed of light. The fact is, the energy of fast flowing elektriklah (which is still slower than the speed of light). Electrons, which has mass, can move at the speed of light by using the theory of relativity. The speed of the electric charge in electric current is very slow, around several centimeters per hour. In places where electric currents can be seen, as in electrophoresis, slow movement of the carrier can be seen directly.

3. Seasons are NOT the Same length

Because the earth moves faster in its orbit as it approached the sun, summer in the southern part of the earth / winter in the northern part of the earth is the shortest time for the season, with summer in the north or south of the longest winter. However, the difference is only felt a few days, while on Mars with an eccentric orbit, the difference was huge.

4. You will not get a cold a just from low temperature

Has become a widespread misconception in the public that the common cold can be caused by cold weather. Reality, the common cold is caused by a virus and has nothing to do with low temperature or cold.

5. Saturn is NOT the only planet with rings

Jupiter, Uranus, and Neptune also have rings around them, although that was in Saturn's rings are the most obvious and easily seen.

6. Meteors are NOT hot when they land on Earth

When a meteor landed on earth, meteors are usually not hot like most of the meteor in Hollywood movies. Usually, only warm. Meteor velocity sufficient to melt the outer surface, but the material that melts quickly separated, and the interior of the meteor did not have time to heat up because rocks are poor heat conductors.

7. Clouds do NOT form because of the air's temperature

Is the wrong knowledge that the clouds are formed from the cold "hold" less water vapor than warm air. Air does not have the capacity to contain water vapor. Only the temperature of the water itself (and vicinity) which causes the humidity, condensation process, and then the formation of clouds.

8. People DID know earth was not flat before Columbus

Some believe that Christopher Columbus had difficulty in receiving support because the people of Europe believe that the earth was flat. In fact, sailors and navigators at that time knew that the earth is round, but (correct knowledge) do not agree with estimates from Columbus of the distance to India. If America does not exist, and Columbus went on his journey to India that actually, he will not be able to survive longer to achieve.

9. The Great Wall of China is NOT particularly visible from space

At the time in low orbit, the Great Wall of China can be seen from outer space but not as unique from the digembor rant. From the low earth orbit, many artificial objects can be seen on earth, not just the Great Wall of China. Highways, ships at sea, dams, railways, cities, rice fields, and several buildings.

As has been claimed that the Great Wall of China is a man-made objects are visible on the Moon, Apollo astronauts have reported that they did not see any human-made object from the moon.

10. There is NO "dark side" of the Moon

Months in orbit synchronous (synchronous orbit), this means, the moon menmbutuhkan exactly the same time to rotate once on its axis with the rotation of the earth. So the moon has the far side / rear / dark / outside, because it always gives the same to the earth's surface when it rotates. When the moon is estimated to be between the Sun and Earth, it dalah time "lunch" at the far side / outside / back of the moon and the night for the side facing the earth. When the Earth between the sun and moon, the part that much experience when "night" and "lunch time" for the part which faces the earth.
