Super-Kamiokande is a huge underground reservoir of water, which was built in Japan to detect neutrinos. It is sub-atomic particles which, in the opinion of physicists are constantly rushing through the universe. Since they do not interact with other matter, they just pass through it. There is only one exception - water. When neutrinos pass through the water molecule, there is a tiny flash of light. This light is so weak that its detection need a tank that can hold a 50,000 tons of purified water, and laid out with countless tubes, photomultiplier tubes.
To remove the interference of cosmic rays reservoir was placed at half-kilometer below the surface.
While these measures did not protect it from itself: in 2001, due to the enormous water pressure one of the photomultipliers blew up.Soon Super-Kamiokande was repaired, and although it confirmed the existence of the neutrino facility in 1998, it is still used today to study the history and evolution of the universe.
A stone's throw from the highest tower in the world, the Burj Khalifa, there is the world's largest shopping center - the Dubai Mall. There is everything that should be in the mall - 1,200 stores, and various snack bars. There is also a five-star hotel, which, in its turn, has a spa and five restaurants.
In addition, there is an aquarium, it is so big that its acrylic viewing panel hit the Guinness Book of Records as the largest viewing panel in the world. There is also a show of fountains, which can be seen from a distance of 20 kilometers. Finally, there are an amusement park and a full-size Olympic ice hockey rink. The center has even its own "dinosaur-resident" - the skeleton of Diplodocus, whose age is 155 million years old.The total area of Dubai Mall is more than one million square meters, it is the area of the two Vatican cities.
Instead of lamenting over the destruction Shigeharu Shimamura found what looked like after the Tsunami as a factory for the production of semiconductors, and said to himself: "Yes, I can use it to solve the problem of world hunger."
So his company Mirai Industry Co., Ltd has turned the biggest factory in the world's to a largest indoor farm, and if you believe the numbers, things are going very well, "room farm" 100 times more productive than usual one, it requires 40% less electricity and 99% less water. 17,500 of high-tech lamps illuminate an area of 2,300 square meters.
The building was built in 532 AD to store water of the Grand Palace in Istanbul (which in those days was still Constantinople). And then people forgot about it. In 1545 the Frenchman Peter Gilius rediscovered this building, after seeing how the locals collect water, dipping buckets directly into the hole in the floor of his basement. Sometimes there were carps in these buckets.
Today fish floats freely among hundreds of giant stone columns. And speaking of the columns, it is worth noting that two of them are decorated with a complex of Roman carvings in the form of the head of Medusa.
Inside Shah Cheragh (or "King of the World"), in Iran is not like a usual mosque. This building looks more like a fortress of solitude. The interior walls are lined with a mosaic of mirrors and colored glass, which forms a complex silver-green pattern, creating the feeling that you are in the Emerald City.
Mosque is an example of traditional Persian mosaic art, but really important pilgrimage Cherah Shah became in the 14th century, when the Queen Tashi Khatun decided to upgrade this place.
Hotel Terme Millepini has the deepest indoor swimming pool in the world. Its depth is 40 meters, which corresponds to the height of 12-storey building. Sometimes the pool is simply called Y-40, and sometimes - «Deep Joy». The pool has underwater caves and inspection panel for those who can not swim, but it is used for diving in leisure time, for diving training and for underwater filming.
And in the second place there is the Belgian Nemo-33. From the title it is clear that the depth of the pool is 33 meters and it contains 2.5 million liters of pure filtered water. This pool also has several underwater caves, and still there are special bells for diving, which enable teachers to talk with students, not rising to the surface.
Now "Tropical Island" is "the biggest tropical festive peace in Europe." So how much material can fit construction, created to give refuge huge flying whale - airship? Well, in a hangar it is possible to put the Statue of Liberty, the Eiffel Tower or the Potsdamer Platz, but instead of that the hangar have internal beaches, lagoons, rainforest, a mini-golf course and a huge screen that simulates sunrise and sunsets. The resort even has its own leitmotif.
