HONG KONG – Hong Kong The physicists succeeded in proving that the photon (light units) single follow Einstein’s theory which says that nothing can be faster than the speed of light, in other words, time travel is impossible.
The team of researchers from Hong Kong University of Science and Technology led by Professor Du Shengwang say they have proved that a single photon ‘follow the laws of the universe’. Similarly, as quoted by Discovery News, Wednesday (27/07/2011).
“Einstein’s claim that the speed of light is at the core laws of the universe, or simply, nothing can surpass be faster than light,” wrote the university on his official website.
“Research Professor Du demonstrate that a single photon, also follow the laws of the universe as electromagnetic waves (EM),” he added.
The possibility of time travel attracted approximately 10 years ago after scientists discovered that the development of optical pulses on certain media capable of faster than light, which later proved to be only a mere visual effect.
Even so, scientists remain convinced that it is still possible for a single photon to exceed the speed of light.
Du believe that Einstein was right and this discovery could establish a long debate in advance about the possibility of time travel.
“In addition, this study also expected to give an overview to the scientists regarding the transmission of quantum information,” added Du.
Deutsches Technikmuseum Berlin
Berlin – German
Deutsches Technikmuseum Berlin (“German Museum of Technology”) was founded in 1982 in Berlin, Germany, first opened in 1983 under the name Museum of Transport and Technology, which it carried until 1996. The museum sees itself as the successor of the over 100 technical collections that have occurred in recent centuries in Berlin, last of the collection for a transport museum in the German Democratic Republic (the Hamburger Bahnhof), has over 25,000 m² and offers a large exhibition space at the site of a Eisfabrikation and pickup of goods and postal station and is visited by 600 000 people annually. focuses mainly of the waterways and rail traffic in / around Berlin and in Germany, beer, jewelry manufacturing and energy production.
The air and space exhibition documents the development on these areas during the 20th Century. Among the numerous exhibits are the only remaining steel-Jeannin Taube, built in 1914, from the beginnings of military aviation. The central object of this exhibition is the commercial aircraft Junkers Ju 52, better known as Aunt Ju. Rare memorabilia, a flight captain of Deutsche Lufthansa and a well-known sport pilot flying light up their everyday lives. The two-seat aerobatic training aircraft travel and Arado Ar 79 shows the state of development of civil aircraft at the aircraft factory Arado before the Second World War. The exhibition area to the Second World War focuses on the rise and fall of the Luftwaffe, and shows how the Nazis abused the fascination of flying for their own purposes. The wreckage of a Junkers Ju 87 Stuka bomber can imagine the destructive potential of the aircraft as a weapon. The media station shows man and war on the basis of six biographies of the lives of former Air Force member. Since March 2008, is a VFW-614 as an example of a German aircraft development after the Second World War in the possession of the art museum.
iPod is a brand of a series of digital media player device that is designed and sold by Apple Computer (Hewlett-Packard also had to sell the product with the name Apple iPod + HP). The name “iPod” is also used to represent the name of one of the variants of digital media players in the circuit (this variant is now called the “iPod classic”). Most of the variants of the iPod provides a user interface (user interface) is simple to use design in the form of steering wheel (scroll wheel). iPod classic storing data on a hard drive, while other models use flash memory. Like most other music player device, the iPod can be used as an external hard drive when connected to a computer.
Tony Fadell was first inspired to make the iPod outside of Apple Computer: the time he was having trouble finding funds to finance the music player device he created.  At the time he showed it to Apple Computer, the company hired him as an independent contractor for fruition of this project. He was given the responsibility to build a team that will develop the first two generations of this device. After that the next iPod developments conducted under the auspices of Jonathan Ive, head of the industrial design group at Apple Computer.
Escalators are one form of vertical transport conveyor for transporting people, consisting of separate steps that can move up and down following the path of a rail or chain-driven motor.
Because it is driven by electric motors, escalator is designed to transport people from the bottom up or vice versa. For short distances escalator used around the world to transport pedestrians where the elevator is not practical. Its use especially in the area shopping centers, airports, transit systems, convention centers, hotels and other public facilities.
The advantage of the escalator pretty much like having the capacity to move a number of people in large numbers and there is no waiting time interval, especially at rush hour and direct people to certain places such as the exit, a special meeting etc.
The Oldest Escalators
The first escalator was made with you in 1859 in New York’s Coney Island amusement park. Because the wooden escalator accidents occurred one of the most famous in history occurred on 18 November, 1987 when the fire spread to the draft in the network of London Underground subway killed 31 people. Sparked the idea to change the basic material into iron.
The Longest Escalator
Park Pobedy station in the Gaza-Pokrovskaya Arbatsko opened in 2003 and an escalator to the length 126.8 m (413 ft), or about 740 steps. From beginning to end, the journey at Park Pobedy escalator can take nearly three minutes.
The Shortest Escalator
Because there are super long escalator which, now that its opposite. Escalator in shopping center Okadaya customs in Kawasaki, Japan, for example, only 32.8 inches long, vertical (83 cm). Approximately 3 steps when walking.
You all must have been listening to songs played on a tape recorder or compact disc (CD). Yes, the songs are the result of a sound recording of the singer. With voice recorder technology, we can save the sound or sounds and listen back anytime we want.
System for storing voice recordings made by sound waves in the band, LPs, or CDs. The process of recording on cassette tape can be done because it consists of a thin ribbon plasik magnetic metal powder coated.
The composition of the metal powders were irregular, but when sound is recorded into the tape, powder was made according to the sound pattern. The powder compact is what saves the recorded voice said, and then can be played anytime to listen to the voice. But to be able to listen to this voice must use the help of loudspeakers (speakers).
For CDs, this tool saves millions of votes in a small gap which represents the symbol of a series of numbers. When the CD spins, the laser beam to read the order of the hole, and the tools CD and then change the reflection ray laser into electricity. Ray is reinforced and connected with a loudspeaker which then issued a re-vote that saved it. Sound is what we hear it.
Keep in mind that each of the recording process starts from migrofon. Migrofon functions convert sound waves into electrical signals. Inside the wire gumparan migrofon there is usually mounted on a diagram. Sound waves and then create charts and coil to vibrate. These coils vibrate in the magnetic field. This vibration and generate electric current in the coil. Strong weak currents changing in accordance with the loud sound of gentle waves.
However, for the recording can be heard again need bantuab speakers. The process works namely, loudspeakers convert electrical signals into sound waves. Electric current from a source, CD or LPs, for example, turn on an electromagnet to form a magnetic field. This is what makes the cone-shaped diaphragm vibrates and then generate sound waves. This sound is the result of earlier recordings.
