Digital Audio Player (1979) so MP3 Player / iPod (1997/2001)
In 1979, Kane Kramer from the UK has a solid idea of pocket-sized music player. Kramer called IXI System and its size is almost as big as a cigarette box. According to the site Kramer, Kramer and his partner making five sets of this. Kramer artificial system is only able to play music for three and a half minutes.
However, he plans to use flash memory to extend it. According to Wired, even Kramer plans to create a music store to download new music. Filing Kramer rights failed in 1998, at the point that this technology became public property. IXI and digital music store has now turned into an iPod and the iTunes store. Apple itself recognize the role of Kramer in the creation of the iPod.
Analytical Engine (1822) so Computer (1940)
In an effort to create mathematical calculating machine without error, Charles Babbage created the forerunner of modern computers. Babbage's analytical engine was the first general computing device that is able to solve different types of calculations. Interestingly, the engine was made at the time in electronics has not emerged. Babbage's analytical engine continues to develop until his death in 1871.
Contact Lens (1632), so Contact Lens (1887/1950)
In 1632, Rene Descartes proposed parangkat to correct vision. This method uses liquid-filled glass tubes that are placed directly on the eye. Unfortunately, users 'lens' is not going to blink.
In 1887, Adolf Eugen Fick optalmolog Germany created the first successful contact lens from glass. This lens can only be used for several hours and finally chemist Otto Wichterle soft contact lens made of plastic. Now, contact lenses are used millions of people around the world.
Colorfax (1947) so Color Printer (1990)
When I first appeared in Popular Science, colorfax machine dubbed the 'new world opens for home and business use'. This machine is capable of drawing in red, blue, yellow and black and needed about 15 minutes to mencetap each picture. Printers today become a liability in many offices.
Photovoltaic Cell (1883) so Solar Cells (1945)
In 1883, Charles Fritts developed the first solar cell after covering the semiconductor selenium with a thin layer of gold. Unfortunately, this device is not effective, its efficiency is only 1%. In 1945, researchers at Bell Laboratories managed to renew it by making efficiency. Since then, the solar cells used on space satellites and small objects such as calculators and watches.
Heat Ray (212 BCE (BCE)) so Heat Ray Gun (2007)
Military United States (U.S.) reveals the Active Denial System four years ago. The system is projecting a transparent high-energy rays that can cause sudden burning feeling. The military said the heat ray gun is not dangerous and can be used to dispel the crowd.
In contrast, the original hot rays during Syrause in 212 BC is used to burn enemy ships. Archimedes made this device to burn the Roman warships. In addition, many parties proves, it is possible to burn Roman ships using these heat rays.
Aeolopile / Automata (first century), so the Steam Engine (1698/1954)
Steam engine is credited as one of the most important creations in the industrial revolution. Steamships and locomotives allow for faster transport between countries or oceans. While the creator of James Watt steam engine, the application first appeared centuries before he was born.
Greek mathematician Hero of Alexandria describes a tool named Aeolopile, the first device to apply steam to the rotary motion. This tool has a blank dots of water on the stove, so when the water boils, steam past him and make a circle in it spins. According to the Encyclopedia Britannica, Hero uses a similar process to create a door that can open automatically.
Watch-Case phonograph (WCP, 1936) so the Walkman (1979)
WCP is described as a tiny music player. Miniature phonograph is commonly found in watches. To hear it, simply hold the WCP on the ear. Unfortunately, the draft WCP is not effective. In 1970, the developer of the Sony Walkman makes the whole concept of this portable device with pre-recorded music in it.
Vehicle Steam Power (1769) so Gas Power Car (1886)
While Nicholas-Joseph Cugnot of Austrian military drawing tools to draw artillery, vehicle steam power regarded as the world's first car. This car has three wheels with one front wheel to function as a referral. After that, Cugnot create a version of bigger, stronger and faster and was completed in 1771.
Unfortunately, according to MadeHow.com, Minister Etienne Francois de Choiseul was not interested. Then, the vehicle was moved to National des Arts et Metiers in Paris and on display there ever since.
Machinery Seller (first century), so Machine Sales (1880)
Vending machines can be found in schools, airports and most of the building. Currently, these machines are in the health debate. This surprising, this machine has been around since the first century and used to distribute the holy water in ancient Greek temple.
According to the Smithsonian Institution, when someone enters a coin, the coin of the panel and the panel makes the water out. This system is also used in a vending machine that was developed in 1880 to eventually take over the task electricity.
