Liquid nitrogen under a vacuum
(2) | 27/06/2014 | Translate: Rapidly boiling liquid nitrogen in a vacuum chamber through pressure turns the nitrogen into a solid. Considering nitrogen is a gas at room temperature and a liquid past the freezing point of water, its exotic properties are rare in the world of physics.
Swimmer Anita Alvarez saved by her coach American swimmer Anita Alvarez lost consciousness in the water during the world swimming championships on Wednesday in Budapest. The rescuers did not react, it was his coach who had to jump into the water. - Meanwhile in Russia… a man plays in the water with a dog, a truck sinks and bottles of gas float
- Greece is sexy! (Travel to #Lefkada Island) Greece is a sexy travel destination! Greek islands are the best in the world whether you're looking for sandy beaches, unspoiled island life or history and culture. Greece has an extremely large number of islands, somewhere around 1,200 to 6,000.. Lefkada is one of them. #placesworthtraveling The spectacular beaches, the green turquoise waters, the small Greek villages make Lefkada an unforgettable island and a special place for your holidays. #travelguide

- Mechanical Elephant This incredible piece of engineering and art is situated in Nantes, France. Do you remember the Giant Spider build by the same two engineers/artists?
The Elephant is 12 metres high, 8 metres wide and 21 metres long; 48.4 tons of steel and wood (tulip. 450 horsepower motor. Spped 1 - 3 kmph. 60 cylinders (44 hydraulic, 6 pneumatic and 10 gas)
Located in the Warehouses of the shipyards that closed in 1987, Les Machines de L'ile is part of the Ile de nantes urban renewal project.
Together with many other mechanical giant insects and many other touristic interests including watching the workers build for their next projects. You will see the Great Elephant in action, the Machine Gallery, Marine World Carousel, Workshop, Cafe, restaurant and gift shop.

- Tommy Wiseau’s Joker Audition Tape (Nerdist Presents) After his success in "The Room" and the "The Disaster Artist," Tommy Wiseau has been publicly campaigning for one of the most iconic roles in the history of film: Batman's eternal nemesis, The Joker. As huge fans, we at Nerdist give him a chance to show the world what he can bring to this legendary role!
- Pumice Rock Lake Chile Pumice stones are highly porous volcanic rocks with low density. This stone contains many bubbles of gas, trapped by the lava which cools rapidly during ejection, hence its low density with an average density of 910 kg / m3 which is lower than that of water, which makes it allows to float.
- CRUISE SHIP CAUGHT IN A BOMB CYCLONE (Norwegian Breakaway) The New Year's Cruise carrying over 4,000 passengers was caught in a violent winter storm on the way back from the Bahamas. The ship was constantly rocking for 3 days! Although the ship is capable of handling such a storm, we saw some people sleeping in the hallways because of water leaking into their rooms from the balcony doors (or because some thought the ship was going to capsize.) We even saw a family walking around with their life jackets.
- Hot Wound Spring for Sub-sea Oil and Gas This video illustrates the manufacturing steps used to create a large spring for use in the sub-sea oil and gas industry. The steel bar used to make this spring is nearly three inches in diameter. and the completed spring will stand nearly five feet tall and weigh approximately 1,000 lbs. The austinitizing, hot-coiling, and quenching processes are shown. Tight process controls are maintained to ensure that the spring will perform throughout its intended life cycle in one of the world's most challenging environments.
- Nuclear Reactor Pulse and Startup Compilation The blue light is known as Cherenkov radiation. It is similar to a sonic boom, but instead of an object travelling faster than the speed of sound, a charged particle is travelling faster than the speed of light in a medium. In this case, the speed of light in water is roughly 75% the speed of light in a vacuum. It tests the time-dependent properties of the fuel. Engineers use that data to predict what would happen if there were an accident at a large reactor Cherenkov radiation, also known as Vavilov–Cherenkov radiation,[a] is electromagnetic radiation emitted when a charged particle (such as an electron) passes through a dielectric medium at a speed greater than the phase velocity of light in that medium. The characteristic blue glow of an underwater nuclear reactor is due to Cherenkov radiation.
Essentially when light passes through different materials its speed can be slowed as the photon makes it way through the medium.

- NASA & TRAPPIST-1: A Treasure Trove of Planets Found Seven Earth-sized planets have been observed by NASA's Spitzer Space Telescope around a tiny, nearby, ultra-cool dwarf star called TRAPPIST-1. Three of these planets are firmly in the habitable zone. Over 21 days, NASA's Spitzer Space Telescope measured the drop in light as each planet passed in front of the star. Spitzer was able to identify a total of seven rocky worlds, including three in the habitable zone, where liquid water might be found. The video features interviews with Sean Carey, manager of the Spitzer Science Center, Caltech/IPAC; Nikole Lewis, James Webb Space Telescope project scientist, Space Telescope Science Institute; and Michaël Gillon, principal investigator, TRAPPIST, University of Liege, Belgium. The system has been revealed through observations from NASA's Spitzer Space Telescope and the ground-based TRAPPIST (TRAnsiting Planets and PlanetesImals Small Telescope) telescope, as well as other ground-based observatories. The system was named for the TRAPPIST telescope.
- The Biggest Shiplift in The World This ship lift is on the Krasnoyarsk HPP. This is a huge bath on the rails, it first calls in on one side of the dam below the water level, is filled with water, and inside swims ship, the gateway is closed and the ship lift rises to the top, where there is a 180-degree turn and descend on the other side of the dam, where the gateway is opened and the ship floats out. Weight without water of 4000 tons of water and the vessel of 8000 tons, the velocity of 1.2 km / h. Officially, it is working since 1982. The video is shipping units for the power plant, which is located upstream of the Yenisei.
- Come on an awesome tour thru a Pygmy village! DEEP in the Congo Rainforest Traditional music - hunter gatherer culture - humanitarian aid - and amazingly sweet people, my family, the Mbuti Pygmies! To get here we have to drive about 5 hours through Eastern Congo, the forest, and on awful dirt "roads" the entire time. Then we have to hike for over 1 hour with over 1 ton of tools, pipes, equipment, and bags of cement, gravel pack, and construction gravel/rocks! That was through the mud and around, under, and over trees in the second largest rainforest in the world. So thankful for the help of the Water4 team supporting our Fight For The Forgotten and Shalom University drilling team! We are currently working on our 15th water well for my Congo family :-)
