The inventor of the generator is still michael faraday. 183 1 year, he designed and manufactured the earliest generator in the world. He found that when a magnet passes through a closed circuit, there will be current in the circuit, which is actually a successful experiment of reverse thinking of the motor principle. Their similarity is based on "electromagnetic induction".
2. Internal combustion engine
1860, French engineer lenoir imitated the structural design of the steam engine and made the first practical gas engine. However, due to low thermal efficiency, it has not been popularized. From 65438 to 0876, the German inventor Nicolas August Otto successfully developed the first four-stroke internal combustion engine by applying the four-stroke working cycle principle proposed by French scientist Rosa.
3. Train
1804, Derry Visk, a British mining technician, made the world's first steam locomotive using coal or firewood as fuel by using Watt's steam engine principle. /kloc-in 0/840, the British engineer Charlie Mrivisik designed and manufactured the world's first real train running on the track. 1879, Siemens electric company of Germany developed the world's first electric locomotive.
4. cars
1886 65438+ 10, two Germans, Carl Benz and gottlieb daimler, obtained the patent right of the world's first car almost at the same time, except that Carl Benz made a three-wheeled car and gottlieb daimler made the world's first four-wheeled car.
5. bicycles
18 17, German baron Karl delaisse made a bicycle with wooden wheels and handlebars on the basis of the bicycle designed by Sifrak in France and Artamaa Novo in Russia, and he also applied for a patent for it. Since then, bicycles have been invented and improved by craftsmen in different countries, and gradually evolved into modern bicycles.
Step 6 print
Printing is one of the four great inventions in ancient China. Printing originated from Taoist woodblock printing, developed and perfected in Bi Sheng, resulting in movable type printing, which was spread to Europe by Mongols. But what really played a revolutionary role was the printing press invented by German Johannes Gutenberg in 1440. His invention triggered a media revolution and quickly promoted the development of western science and society.
