1 Nobel
1863, 10, Nobel obtained the invention patent of explosive initiator. This invention is called "Nobel Igniter". 1864 obtained the invention patent of nitroglycerin explosive. 1865, he developed a solid ductile fuel through repeated experimental research, and obtained patents for explosives in Sweden, Britain and the United States.
1866, a "diatomite explosive" was made, which can absorb three times more nitroglycerin than itself and is as soft as clay. This product will become the cornerstone of Nobel International Industrial Group in the future.
2. The Wright brothers
The Wright brothers are famous American inventors. Their elder brother is wilbur wright and their younger brother is Orville Wright. 1903 12 17, the Wright brothers made the first test flight of a fully controlled, self-powered and heavier-than-air plane, which was the world's first plane, Voyager 1.
3. Guillermo Marconi
1874 On April 25th, Guillermo Marconi was born in Bologna. His family is very rich and he studies under the guidance of a tutor. During his study in Bologna University, he used electromagnetic waves to conduct a radio communication experiment with a distance of about 2 kilometers, which was successful. 1937 is dead.
1897, Marconi wireless telegraph company was established in London. 1909 won the nobel prize in physics with Braun, and was called "the father of radio".
4. John Logie Baird
British scientist John Logie Baird has been trying to transmit TV images through mechanical scanning. 1925 10 year 10.2, he finally made the first mechanical TV set that can transmit images, which is the prototype of TV.
Although the puppet's face is fuzzy and noisy, seeing vivid images in an inconspicuous black box still attracts great interest. This new TV is called "Magic Box".

The Father of Classical Mechanics —— isaac newton
Sir isaac newton (1643 65438+1October 4th-1727 March 3rd1), chairman of the Royal Society, a famous British physicist, is an encyclopedic "all-rounder" and author of Mathematical Principles of Natural Philosophy and Optics.
He described gravity and three laws of motion in the paper "Laws of Nature" published by 1687. These descriptions laid the scientific view of the physical world in the next three centuries and became the basis of modern engineering.
By demonstrating the consistency between Kepler's law of planetary motion and his theory of gravity, he showed that the movements of ground objects and celestial bodies all follow the same natural law; It provides strong theoretical support for the sun-centered theory and promotes the scientific revolution.
