The biggest dam in the world
Three Gorges Dam, in Hubei Province, China, will be the world's largest dam and largest concrete structure and create the largest lake. The dam will be built across the 3 Gorges section of the Yangtze River. It will be a 610-foot high wall running about 1.3 miles from bank to bank. Requiring 12 years and tens of thousands of workers to complete, the dam will cost $29 billion, and will create a 370 mile long lake, a distance equal to nearly half the length of California, that will be visible from Earth orbit.

How the eye works Plus a lesson in psychology.
Learn something else a short lesson of group dynamics, how psychologists used an optical illusion to discover something really interesting!
This is just a diagram of the eye, and how the eye relays the images to the brain to form pictures. This is one of the few pictures on cool optical illusions that is NOT an optical illusion. Notice that the picture of the flower actually gets formed on the retina upside down! Your brain actually flips the image right side up.
Time to learn something:
Scientists actually did a study on some people by giving them mirrored glasses, which they were required to wear constantly for days. These glasses had the effect of making everything they saw turn upside down. Although very awkward at first, after a week or so their brains actually started flipping the images right side up, and it was just like before! Then when they took off their special glasses, everything was upside down for a while as their brain adjusted!
Did you know that if you project a spot of white light on a wall in a dark room, and look at it for a few minutes, it will appear to move? Even though it does not actually move? Psychologists used this in a famous experiment where they would take a group of people and show them the spot of light. Then they would ask how far the light moved. The interesting thing is that the psychologists actually had only one real participant in the group, and the rest were working for the psychologist.
In group A, The "workers" would all report a much larger distance than they had actually seen: for example 14 inches. Then Participant A would answer. In group B, they would have the participant verbally give the answer first, so as not to be swayed by the group. As you might expect, the participants in group A reported a much larger movement than those in group B, even though they had seen the same thing!
Furthermore, the participants in group A didn't only report a larger number to sound better to the group, they truly BELIEVED that they saw the line move much farther.
So just remember, if you are trying to persuade someone to believe something, a technique you can use is to have others who share your opinion talk about it first, so that the person sees that they are in the minority. They just might start to remember things differently.

Amazing Captivating Fractals Found in Nature
Fractals are purely a wonder too irregular for Euclidean geometry; iterative and recursive and seemingly infinite. Here are seventeen stunning examples: Amazing Captivating Fractals Found in ours Beautiful Nature.They turn up in food and germs, plants and animals, mountains and water and sky. Fractals: they’re famously found in nature and artists have created some incredible renderings as well.
Sea shells
The nautilus is one of the most famous examples of a fractal in nature. The perfect pattern is called a Fibonacci spiral.
Snow flake
Lightning
Lightning’s terrifying power is both awesome and beautiful. The fractals created by lightning are fascinatingly arbitrary and irregular.
Romanescu
A special type of broccoli, this cruciferous and tasty cousin of the cabbage is a particularly symmetrical fractal. Cook it for your favorite mathematician.
Fern
The fern is one of many flora that are fractal; it’s an especially good example.
Queen Anne’s Lace
The delicate Queen Anne’s Lace, which is really just wild carrot, is a beautiful example of a floral fractal. Each blossom produces smaller iterative blooms. This particular image was shot from underneath to demonstrate the fractal nature of the plant.
Broccoli
Though not as famously geometric as its relative the Romanescu, broccoli is also a fractal.
Peacock
Males of both the white peacock and standard peacock variety are resplendent examples of fractals in the animal kingdom. Trivia: the white peacock is not an albino.
Pineapple
The pineapple is an unusual fruit that is, in fact, a fractal. Though often associated with Hawaii the fruit is a native of southern Brazil.
Clouds
Look outside your window - you may see a fractal cloud at any moment.
Crystals
Both chemically-formed crystals and ice and frost crystals are breathtaking examples of fractals in nature.
Mountain
Mountain ranges both shorelines and mountain ranges are considered loosely fractal. These particular examples are beautiful ranges
Both shorelines and mountain ranges are considered loosely fractal. These particular examples are beautiful.
Trees and Leaves
From the macro view of a leaf to the span of a tree’s branches, fractals turn up frequently.
Shorelines
This stunningly complex fractal shoreline is none other than the pan handle of Florida.
Rivers and fjords
From the mid west of the United States to the icy fjords of Norway, fractals are often viewed by airline passengers - these particular travelers were savvy enough to snap photographs.
Sea urchins and sea stars
Sea urchins are compact, almost artistic little creatures; sea stars are more commonly referred to as starfish.
Stalagmites and stalactites
By now you know that stalagmites shoot up from the ground while stalactites form overhead.

Most Beautiful Unique Lakes of our World
Nature is always a great motivator for learning our world, Here are the Most Beautiful Unique Lakes of our World
The Plitvice Lakes are a series of sixteen lakes interconnected by spectacular waterfalls, set in a deep woodland and populated by deers, bears, wolves, boars and rare bird species. A UNESCO World Heritage Site, the lakes are renowned for their distinctive colours, ranging from azure to green, grey or blue. The colours change constantly depending on the quantity of minerals or organisms in the water and the angle of sunlight.
Plitvice Lakes (Croatia): Sixteen Lakes interconnected by Spectacular Waterfalls
Boiling Lake (Dominica): A Flooded Fumarole
The Boiling Lake is situated in the Morne Trois Pitons National Park, Dominica's World Heritage site. It is a flooded fumarole, or hole in the earth’s surface, 10.5 km east of Roseau, Dominica, on the Caribbean. It is filled with bubbling greyish-blue water that is usually enveloped in a cloud of vapor. The lake is approximately 60 m across.
Red Lagoon (Bolivia): Red (algae) + White (borax)
The Laguna Colorada (Red Lagoon) is a shallow salt lake in the southwest of the altiplano of Bolivia, close to the border with Chile. The lake contains borax islands, whose white color contrasts nicely with the reddish color of its waters, caused by red sediments and pigmentation of some algae.
Five-Flower Lake (China): Beautiful Multi-Coloured Lake with Fallen Tree Trunks
The Wuhua Hai, or Five-Flower Lake, is the signature of the Jiuzhaigon National Park in China. The lake is a shallow multi-coloured lake whose bottom is littered with fallen tree trunks. The water is so clear that you can see the trunks clearly. The water comes in different shares of turquoise, from yellowish to green, to blue. It is located at an elevation of 2472 meters, below Panda Lake and above the Pearl Shoal Waterfall.
Dead Sea (Israel and Jordan): Lowest Point on Earth
The Dead Sea is a salt lake situated between Israel and the West bank to the west, and Jordan to the east. It is 420 meters (1,378 ft) below sea level and its shores are the lowest point on the surface of the Earth on dry land. The Dead Sea is 330 m (1,083 ft) deep, the deepest hypersaline lake in the world. It is also the world's second saltiest body of water, after Lake Assal in Djibouti, with 30 percent salinity. It is 8.6 times saltier than the ocean. This salinity makes for a harsh environment where animals cannot flourish and boats cannot sail. The Dead Sea is 67 kilometers (42 mi) long and 18 kilometers (11 mi) wide at its widest point. It lies in the Jordan Rift Valley, and its main tributary is the Jordan River.
The Dead Sea has attracted visitors from around the Mediterranean basin for thousands of years. Biblically, it was a place of refuge for King David. It was one of the world's first health resorts (for Herod the Great), and it has been the supplier of a wide variety of products, from balms for Egyptian mummification to potash for fertilizers.
Lake Baikal (Russia): Deepest and Oldest Lake in the World
Lake Baikal is located in Southern Siberia in Russia, and it's also known as the "Blue Eye of Siberia". It contains more water than all the North American Great Lakes combined. At 1,637 meters (5,371 ft), Lake Baikal is the deepest lake in the world, and the largest freshwater lake in the world by volume, holding approximately twenty percent of the world's total fresh water. However, Lake Baikal contains less than one third the amount of water as the Caspian Sea which is the largest lake in the world. Lake Baikal was formed in an ancient rift valley and therefore is long and crescent-shaped with a surface area (31,500 km²) slightly less than that of Lake Superior or Lake Victoria. Baikal is home to more than 1,700 species of plants and animals, two thirds of which can be found nowhere else in the world and was declared a UNESCO World Heritage Site in 1996. At more than 25 million years old, it is the oldest lake in the world.
Lake Titicaca (Bolivia and Peru): World's Highest Navigable Lake
Lake Titicaca is a lake located on the border of Bolivia and Peru. It sits 3,812 m (12,500 ft) above sea level making it the highest commercially navigable lake in the world. By volume of water it is also the largest lake in South America. Lake Titicaca is fed by rainfall and meltwater from glaciers on the sierras that abut the Altiplano.
Caspian Sea (Russia): World's Largest Lake
The Caspian Sea is the world's largest lake or largest inland body of water in the world, and accounts for 40 to 44 percent of the total lacustrine waters of the world. With a surface area of 394,299 km² (152,240 mi²), it has a surface area greater than the next six largest lakes combined.
Crater Lake (USA): its waters are considered one of the World's Most Clearest
Crater Lake is a caldera lake located in Oregon; due to several unique factors, most prominently that it has no inlets or tributaries, the waters of Crater Lake are considered one of the world's most clearest. The lake partly fills a nearly 4,000 foot (1,220 m) deep caldera that was formed around 5,677 (± 150) BC by the collapse of the volcano Mount Mazama. Its deepest point has been measured at 1,949 feet (594 m) deep, making it the deepest lake in the United States, and the ninth deepest in the world.
Lake Karachay (Russia): Most Polluted Spot on Earth
Lake Karachay is a small lake in the southern Ural mountains in western Russia. Starting in 1951 the Soviet Union used Karachay as a dumping site for radioactive waste from Mayak, the nearby nuclear waste storage and reprocessing facility, located near the town of Ozyorsk. According to a report by the Washington, D.C.-based Worldwatch Institute on nuclear waste, Karachay is the "most polluted spot" on Earth. The lake accumulated some 4.44 exabecquerels (EBq) of radioactivity, including 3.6 EBq of Caesium-137 and 0.74 EBq of Strontium-90. For comparison, the Chernobyl disaster released from 5 to 12 EBq of radioactivity, however this radiation is not concentrated in one location.

The Seven Mile Bridge, in the Florida Keys, runs over a channel between the Gulf of Mexico and the Florida Strait, connecting Key Vaca (the location of the city if Marathon, Florida) in the Middle Keys to Little Duck Key in the Lower Keys. Among the longest bridges in existence when it was built, it is one of the many bridges on US 1 in the Keys, where the road is called the Overseas Highway.
9. San Mateo-Hayward Bridge
The San Mateo-Hayward Bridge (commonly called San Mateo Bridge) is a bridge crossing California's San Francisco Bay in the United states, linking the San Francisco Peninsula with the East Bay. More specifically, the bridge's western end is in Foster City, the most recent urban addition to the eastern edge of San mateo. The eastern end of the bridge is in Hayward. The bridge is owned by the state of California, and is maintained by Caltrans, the state highway agency.
8. Confederation Bridge
The Confederation Bridge (French: Pont de la Confederation) is a bridge spanning the Abegweit Passage of Northumberland Starit, linking Prince Edward Island with mainland New Brunkswick, Canada. It was commonly referred to as the "Fixed Link" by residents of Prince Edward Island prior to its official naming.
