A team of students from the National University of Singapore have created the first personal flying machine, called Snowstorm.
Snowstorm is an electric aircraft that can be raised and lowered vertically, and can be controlled by a person.
The vehicle, which looks like a giant drone, has place only for one person, and is equipped with 24 screw that are placed on a hexagonal skeleton. The giant drone has six wheels that help to lower to the ground. Electric vehicle can only fly for five minutes, and only indoors. He has a bad side that does not provide safeguards for the person who sits on it, so a crash could result fatal. Despite this, Snowstorm can serve as inspiration for others to develop personal aircraft that we can use in the real world.

Machine gun with the greatest power of the fire, which is still in military use, is "M134 Minigun". This gun, designed in the late 1960s for helicopters and armored vehicles - according to the Guinness Book of Records - 6000 has capacity of shots per minute, or 100 shots per second. What else to say, "M134 Minigun" is really frightening weapons which produces ten times more 7.62mm caliber bullets than a normal machine gun However, despite his formidable capacity - the machine gun today may seem a simple toy, compared with other deadly concoction. Below we present ''The Metal Storm Gun'', the prototype of a devastating weapon with 16,000 shots per second , respectively 1 million such minute. This automatic weapons, respectively automatic system was developed by a company of arms from Australia with the same name. In 2007, Metal Storm Inc. signed a contract to supply the US Army with this type of deadly weapon, which right now is dedicated to warships, naval Well, reports Business Insider. In the video material that we brought below could see this weapon work looks really scary .

Scientists believe they have proved Einstein's theory of general relativity. The scientist spoke a century ago for gravitational waves, whose existence was proved just now. Panel of scientists arrived at this conclusion while observing the alignment of time and space after the collision and merger of two black holes more than a billion light years from Earth. The group of international scientists says this is the first time that proved the existence of those that Einstein called "gravitational waves" that are changing the space-time extension depending on the reinforcement and fading field of gravity. The greater the gravity field is, the smaller is the space-time extension and vice versa, or under the principle of Einstein, "time flows more slowly where gravity is lower." The capture of gravitational waves is difficult because the signal arrives in poor soil, unless it is a gravitational activity "normal", but the collision of two black holes seems to have been the "talisman" of scientists. This is the first time that the universe speaks to us through gravitational waves. So far we were deaf, "said David Reitze excited, executive director of the LIGO project, engaged in research for years.
To understand the importance of intelligence suffices to note Danzmann Karsten comment, a German physicist and one of the most significant names in this field.
"This is the biggest discovery in physics since the discovery of the Higgs particle's. This invention is for a Nobel Prize, and is nothing to be discussed about it", he says.
Albert Einstein talked about the existence of gravitational waves almost 100 years ago. Einstein predicted that if gravity in an area of the universe changes abruptly as a result of an event of violent cosmic, like the explosion of a star, or in this case the collision of two black holes are created gravitational waves that spread at the speed of light in all universe, and in this process space and time are warped during their movement.
Gravitational waves were captured on September 14 last year, but the group of scientists decided to publish a report with its findings only now after consultation with a panel of 1,000 physicists and astronomers most prestigious in the world.

English physicist and cosmologist, Stephen Hawking, surprised the scientific community last week when he announced during a speech at Cambridge University where he actually believed that after the creation of the universe was a form of intelligence.
By introducing himself in front of the students at Cambridge University scientist world-famous Hawking said that his years of research on the creation of the cosmos have led it to set aside a factor of weird science which he says is in many ways at odds with the universal laws of physics.
This strange phenomenon which he calls "God factor", has been at the origin of the creation process and must have played a major role in determining the actual shape of the Universe. However, his previous statements have suggested that he did not believe in God. In his lecture, Hawking told his audience that if you find yourself trapped in a black hole, there is still hope for you. Perhaps one day the Creator will cause a change in the force of the black hole invaluable, and you will be release. In the end we have no reason not to believe that all this endless space where we live in, someone might be there, in any form, and that this may be our God. Is that an interesting news?

In 2004 a luxury German car brand named Maybach built the unique super car Maybach Exelero. This car have 700hp with a twin-turbo, and with power can reach a speed 217mph (351km/h). For the first time Maybach Exelero was tested on May 2015 and racing driver Klaus Ludwig drove the Maybach Exelero fitted with Fulda
tires in Nardo/Italy and attained a speed of 351.45 km/h – setting a new
world speed record for limousines on series-production tires. Maybach Exelero was inspired by Mercedes-Benz engineers. The Maybach Exelero is definition of speed, luxury and comfort. Also this super car is the most expensive car built so far. The price is average to 8 million dollar, and this is a limited edition produced, only six prototypes. The first who bought this car was rapper Birdman, in 2011 he paid 8 million dollar to have this super car. A dream super car that only 6 billionaires can have it, the others just can enjoy the view.

A brinicle (brine icicle, also known as ice stalactite) forms beneath sea ice when a flow of extremely cold, saline water is introduced to an area of ocean water, being the undersea equivalent of a hollow stalactite or icicle.
The formation of a brinicle was first filmed in 2011 by producer Kathryn Jeffs and cameramen Hugh Miller and Doug Anderson for the BBC series Frozen Planet.
Structure
At the time when a brinicle starts to created it resembles a pipe of ice reaching down from the underside of a layer of sea ice. Inside the pipe is the super cold, super saline water being produced by the growth of the sea ice above, accumulated through brine channels. At first, a brinicle is very fragile; its walls are thin and it is largely the constant flow of colder brine that sustains its growth and hinders its melt that would be caused by the contact with the less cold surrounding water. However, as ice accumulates and becomes thicker, the brinicle becomes more stable. A brinicle can, under the proper conditions, reach down to the sea floor. To do so, the flow of super cold brine from the pack ice overhead must continue, the surrounding water must be significantly less saline than the brine, the water cannot be very deep, the overhead sea ice pack must be still, and currents in the area must be minimal or still. If the surrounding water is too saline, its freezing point will be too low to create a significant amount of ice around the brine plume. If the water is too deep, the brinicle is likely to break free under its own weight before reaching the sea floor. If the icepack is mobile or currents too strong, strain will break the brinicle. Under the right conditions, including favorable ocean floor topography, a brine pool may be created. However, unlike brine pools created by cold seeps, brinicle brine pools are likely to be very transient as the brine supply will eventually cease.On reaching the sea floor, it will continue to accumulate ice as surrounding water freezes. The brine will travel along the sea floor in a down-slope direction until it reaches the lowest possible point, where it will pool. Any bottom-dwelling sea creatures, such as starfish or sea urchins can be caught in this expanding web of ice and be trapped, ultimately freezing to death.Source: Wikipeda

A rotary snowplow is a piece of railroad snow fighting equipment with a large circular set of blades on its front end that rotate to cut through the snow on the track ahead of it. The precursor to the rotary snowplow was the wedge snowplow. The rotary was invented by Toronto, Ontario, Canada dentist J.W. Elliot in 1869. He never built a working model or prototype, although he wanted to.In 2001, the rotary snowplow was inducted into the North America Railway Hall of Fame. The hall of fame recognizes and establishes and enduring tribute to the people and things that have made significant contribution relating to railway industry in North America. The rotary snowplow was inducted in the "Technical Innovations" category with "National" significance.
2. Tiger stone
The amazing machine, named Tiger-Stone, can create an instant road wherever it travels, laying out bricks in formation to create perfect paving.While the process may look magical, the secret behind the invention lies in a smartly-designed gravity-based system.All a worker has to do is load the bricks by hand from a hopper into the Tiger-Stone in the desired pattern. From there gravity causes them to slide together, in a sheet of paving, onto the ground.Brick roads have long been sought-after due to their attractiveness and durability but have become less common because of the labour-intensive work that goes into laying them, compared to other road surfaces such as concrete or asphalt.However, with a Tiger-Stone workers are able to lay out 400 square meters of new road every day, using paving stones or bricks, compared to a single conventionalpaveron their hands and knees who would only be able to manage between 75 and 100 square meters.
3. Replacing the sleepers without removing the rails
Railroad tracks are made of three main parts: the long steel rails that the trains run on, wooden or concrete railroad ties (US) or sleepers (UK), and the track ballast that helps bear a train’s weight and keeps the track clear of plants. As a part of track maintenance, sleepers might need replacement, but they’re under the rails and crushed rock. How do you get them out? The machine uses its sleeper changer attachment to push the ballast away before grabbing the concrete sleeper to remove it. The rails are never disturbed. Watch as each step of the track rehabilitation process is explained, including how the sleepers are reattached to the rails using rail fastening clips before the ballast is smoothed back out.
4. Segmental bridge construction machine
This colossal machine is called the SLJ900/32, or the Segmental Bridge Launching Machine. Created by Beijing Wowjoint Machinery Co, it can build this viaduct by extending beyond the installed segments to span to the next support, and roll the next pre-made bridge segment into place.
5. Barrier transfer machines
Barrier transfer machines, also known as zipper machines or road zipper, are heavy vehicles used to transfer concrete lane dividers, which are used to relieve traffic congestion during rush hours.The vehicle contains an S-shaped channel in its undercarriage which lifts the barrier segments (which may weigh over 1,000 pounds (454 kg) off the road surface and transfers them over to the other side of the lane, reallocating traffic lanes to accommodate increased traffic for the currently dominant (peak) direction. These barriers are linked together with steel connectors to create a sturdy but flexible safety barrier.
6. Rallwayconstruction machine
For the control and monitoring system of a new generation of railway lines electrification machines, Italian-based company Tesmec chose TTControl as technology partner for the constant tension stringing unit and the catenary maintenance diagnostic unit. By using TTControl's HY-eVision operator interface together with an HY-TTC 94 ECU and four HY-TTC 48X I/O modules, it was possible to integrate and manage all different functions of the catenary maintenance diagnostic unit. Additionally, a modular, flexible and adaptable system has been established thanks to the versatility and configurability of TTControl’s control units.
