The unique “diving” bridge between Sweden and Denmark 9/18/2015 • Johnny Crepaul
This engineering marvel connects the two countries and is the longest European viaduct that combines a railroad and a highway. It was open to the public in 2000 and looks especially impressive from above.
If you are good at geography you remember that these two European countries are separated by a narrow strip of water – the strait Øresund (more commonly known in English as the Sound). The strait looks like a strip only on the map – in reality it is not so narrow and has the width of 10 mi or 16 km. Before the bridge had been built people had to travel by ferry in order to reach the bank of the neighboring country, but it took a lot of time. That's why authorities decided to construct a bridge that would connect the countries.
The bridge is really one of a kind. It is a gigantic two-level construction: the lower level is aimed for trains and the upper one – for motor vehicle transport. The viaduct ends up with an artificial island as if diving into the sea. Actually, here an underwater tunnel starts.
Such extraordinary type of construction was chosen on purpose: it doesn't create any obstacles for landing airlines (there is an airport nearby) and allows large ships to pass unimpeded.
Beauty of Science project has published a video showing how chocolate dragees M&M'S are dissolved in water in slow motion. The camera with macro effect and 4K resolution gives the impression that a real supernova explodes. It drew attention of publishing company PetaPixel. This is so fantastic!
The HST is a huge achievement of mankind. It allows us to learn more about outer space and the furthest galaxies. However, do you know something about the telescope that helped to disclose so many secrets about cosmos?
There are so many professionals who can distinguish individual odors in a fragrance made of hundreds of scents. However, can an ordinary person develop such an ability? Watch the video about three simple steps to a better nose!
If you agree that keeping the environment clean is important, then you'll like the thing that the Italians came up with. They developed a building consisting of eco-friendly materials that can purify the air.
Technologies keep surprising us! Researchers from Caltech and the University of Illinois at Urbana-Champaign created an amazing example of biomimicry. A Bat bot is a robot that has silicone wings. Changing shape of the wings during flight the robot looks so natural you wouldn't believe it's a bot! Watch this exciting video and see for yourself.
