World's Greatest Infrasturcures

1. Tallest Skyscraper:
At a height of 2,700 feet, the Burj Khalifa in Dubai has 162 floors and was completed in 2010. If you’re looking for sheer quantity of skyscrapers, Hong Kong has the largest number of high-rise buildings in the world but Benidorm, Spain has the most high-rises per person.
2. Longest Train Track:
The network of rails called the Trans-Siberian Railroad in Russia is the longest train track in the world. The track connects Moscow to the far east of Russia and to the Sea of Japan. An important economic and military development, the railroad has been credited with the growth of several larger cities in Siberia.
3. Longest Railway Tunnel:
The Gothard Base Tunnel, located beneath the Swiss Alps, will soon be the longest railway tunnel in the world. Set to be completed in 2017, the $12 billion project will be longer than the undersea Seikan Tunnel in Japan. With a route length of 35.4 miles, the tunnel should boost trade and travel in Europe.
4. Largest Single-Dish Telescope:
The Arecibo Observatory in San Juan, Puerto Rico is the world’s largest single-dish radio telescope. You’ll probably recognize the telescope’s 1,000-foot-wide telescope from Hollywood appearances in both the James Bond movie “Golden Eye” and in “Contact” with actress Jodie Foster.
5. Highest Residential High-Rise Building:
The highest residential high-rise building is located in Gold Coast City, Australia. The Q1 Tower is both a resort facility and offers exclusive luxury apartments with a “stunning beachside location,” an observation deck 771 feet above the ground, and 360 degree views.
6. World’s First Billion-Dollar Home:
A 27-story skyscraper in downtown Mumbai carrying a price tag near $2 billion is the world’s first billion-dollar home. The home is owned by India’s richest man, Mukesh Ambani, who runs petrochemical giant Reliance Industries.
7. Tallest Engineered Dam:
The Nurek Dam, located on the Vakhsh River in Tajikistan, is the tallest engineered dam in the world. The dam is an important source of electricity for the country.
8. Longest Cable-Stayed Bridge:
Spanning 8,146 meters above the Jiangsu Province in China, the Suzhou-Nantong Highway Bridge is the world’s longest cable-stayed bridge. The bridge has linked the two prosperous cities of Nantog and Suzhou, shortening the journey between the two from a four-hour ferry ride to just a one-hour drive across the bridge.
9. World’s Deepest Mine:
South Africa’s Mponeng mine is the world’s deepest, sending miners and equipment 2.4 miles underground in search of gold.
10. Busiest Airport in the World:
The busiest airport in the world is the Atlanta-Hartsfield Airport in the U.S. The Georgia airport saw 89 million passengers in 2010. It’s also notorious for lengthy delays.

Facts About H2O

1. Roughly 70 percent of an adult’s body is made up of water.
2. At birth, water accounts for approximately 80 percent of an infant’s body weight.
3. A healthy person can drink about three gallons (48 cups) of water per day.
4. Drinking too much water too quickly can lead to water intoxication. Water intoxication occurs when water dilutes the sodium level in the bloodstream and causes an imbalance of water in the brain.
5. Water intoxication is most likely to occur during periods of intense athletic performance.
6. While the daily recommended amount of water is eight cups per day, not all of this water must be consumed in the liquid form. Nearly every food or drink item provides some water to the body.
7. Soft drinks, coffee, and tea, while made up almost entirely of water, also contain caffeine. Caffeine can act as a mild diuretic, preventing water from traveling to necessary locations in the body.
8. Pure water (solely hydrogen and oxygen atoms) has a neutral pH of 7, which is neither acidic nor basic.
9. Water dissolves more substances than any other liquid. Wherever it travels, water carries chemicals, minerals, and nutrients with it.
10. Somewhere between 70 and 75 percent of the earth’s surface is covered with water.
11. Much more fresh water is stored under the ground in aquifers than on the earth’s surface.
12. The earth is a closed system, similar to a terrarium, meaning that it rarely loses or gains extra matter. The same water that existed on the earth millions of years ago is still present today.
13. The total amount of water on the earth is about 326 million cubic miles of water.
14. Of all the water on the earth, humans can used only about three tenths of a percent of this water. Such usable water is found in groundwater aquifers, rivers, and freshwater lakes.
15. The United States uses about 346,000 million gallons of fresh water every day.
16. The United States uses nearly 80 percent of its water for irrigation and thermoelectric power.
17. The average person in the United States uses anywhere from 80-100 gallons of water per day. Flushing the toilet actually takes up the largest amount of this water.
18. Approximately 85 percent of U.S. residents receive their water from public water facilities. The remaining 15 percent supply their own water from private wells or other sources.
19. By the time a person feels thirsty, his or her body has lost over 1 percent of its total water amount.
20. The weight a person loses directly after intense physical activity is weight from water, not fat.
