Question 3: Which scientists invented some great inventions? Edison invented electricity, Newton and gravity. Nobel, explosives. Watt, steam engine. Bi Sheng, letterpress printing. Zhang Heng, seismograph, etc.
Question 4: What are the stories about scientists' inventions? 20-minute copier (urgently needed)
At first, Edison invented paraffin paper, which was only widely used as packaging material for food and candy. Later, he tried to carve the outline of the words on wax paper to form a wax lettering paper tray, put white paper under the paper tray, and then rolled it off the wax lettering paper with an ink roller. A wonderful thing happened, and clear handwriting appeared on the white paper. Later, after many improvement experiments, Edison began to mass-produce the copier he invented in 1976, and all of a sudden institutions, schools, institutions and organizations adopted this stencil mimeograph. Because Edison's copier is very popular all over the world, Edison deeply realized that he should invent things that people generally and deeply need.
Synchronous transmitter
Early telegrams could only transmit one message at a time, but could not exchange signals at the same time. Because Edison himself was a telegraph technician, he began to improve the traditional telegraph and made a double telegraph. 1974, he developed a quadruple telegraph, which is also a synchronous telegraph. At that time, before the development of radio, synchronous transmitter was a major breakthrough.
Improved telephone
As we all know, the modern telephone was invented by Bell. In fact, the telephone can send and receive clearly, thanks to Edison's repeated experiments, which broke through the traditional pattern and made a toner transmitter, which improved the sensitivity, volume and receiving distance of the telephone in one fell swoop. Otherwise, you will often say hello when you call now! Hey! I can't hear you. I can't hear you clearly.
The phonograph was born.
1877 One night in February, the staff of Mengluoyuan Laboratory trembled slightly, not because of the cold, but because they heard the recording for the first time in human history: "Ma P has a little sheep, and its fur is as white as snow. No matter where Ma P goes, the lamb is always by her side ... This great invention needs no more introduction from the little jar teacher. France * * *, and therefore awarded the title of Sir Edison! Later, Edison made many improvements to the phonograph until the drum was changed to a bakelite turntable. This is not a year or two, but after decades of continuous improvement!
lightbringer
/kloc-at the beginning of the 0/9th century, people began to use gas lamps, but gas was supplied by pipelines. Once it leaks or is blocked, it is very prone to accidents, and people are very eager for the reform of lighting. In fact, Edison set himself an impossible task: in addition to improving lighting, he must also create a power supply system.
So he and his partners in Luomeng Garden made more than 600 experiments on heat-resistant materials and more than 600 kinds of plant fibers 1600 times before they made the first carbon filament light bulb, which can burn for 45 hours at a time. Later, he constantly improved the manufacturing method on this basis, and finally introduced a bamboo filament light bulb that can ignite 1200 hours.

2. Li Siguang (188910/October 26th-1971April 29th)
Mongolian, Zizhonggong, 1889 10/kloc-0 was born in a poor family in Huanggang County, Hubei Province on October 26th. (Another saying is1889165438+10/8). He is a world-famous scientist, geologist, educator and social activist, and the founder of modern earth science and geological work in China. Li Siguang's greatest contribution is to establish geomechanics, study the phenomena of crustal movement from the mechanical point of view, and explore the laws of geological movement and mineral distribution, and the new Cathaysian tectonic system. Theoretically, it overturns the conclusion that China is poor in oil and affirms that China has good oil storage conditions.

Question 9: What are the modern scientists and inventions? 1。 A very strange small gas analyzer was successfully copied from annoying flies. It has been installed in the cockpit of the spacecraft to detect the composition of the gas in the cabin. 2。 From fireflies to artificial luminescence; 3。 Electric fish and volt batteries; 4。 The windward ear of jellyfish imitates the structure and function of jellyfish ear, and designs a storm predictor of jellyfish ear, which can predict the storm 15 hours in advance, which is of great significance to navigation and fishery safety. 5。 According to the visual principle of frog eye, people have successfully developed an electronic frog eye. This kind of electronic frog's eyes can accurately identify objects with specific shapes like real frog's eyes. After installing electronic frog eyes in radar system, the anti-jamming ability of radar is greatly improved. This radar system can quickly and accurately identify aircraft, ships and missiles with specific shapes. In particular, it can distinguish between true and false missiles and prevent false confusion. Electronic frog eyes are also widely used in airports and traffic arteries. At the airport, it can monitor the take-off and landing of aircraft, and call the police in time if it is found that the aircraft is about to collide. On the main road, you can direct the vehicles to prevent them from colliding. 6。 According to the principle of bat ultrasonic locator, people also copied "Pathfinder" for the blind. This pathfinder is equipped with an ultrasonic transmitter, which blind people can use to find telephone poles, steps, people on bridges, etc. Nowadays, "ultrasonic glasses" with similar functions have also been made. 7。 By simulating the incomplete photosynthetic mechanism of cyanobacteria, a bionic photolysis device was designed to obtain a large amount of hydrogen. 8。 According to the study of human skeletal muscle system and bioelectricity control, a human strength enhancer-walking machine is copied. 9。 The hook of modern crane originated from the claws of many animals. 10。 Corrugated roofs imitate animal scales. 1 1。 Paddles imitate the fins of fish. 12。 Saw mantis arms, or saw grass. 13。 The plants of Xanthium were inspired to invent velcro. 14。 Lobster with keen sense of smell provides people with the idea of making odor detectors. 15。 Gecko toes provide an encouraging prospect for manufacturing reusable adhesive tape. 16。 The colloid formed by shellfish and protein is very strong, and this colloid can be used in everything from surgical suture to ship repair. 17. The capsules in squid and torpedo bait can secrete black liquid. When it is in danger, it will release this black liquid to trick the attacker into falling for it. Submarine designers imitate this function of squid, and readers design torpedo bait. Torpedo vinegar lure is like a pocket submarine, which can sail at the same speed according to the original course of the submarine, and can also simulate noise, spiral beat, sound signal and Doppler tone change. It is this vivid performance that makes it difficult to tell whether the enemy submarine or the attacked torpedo is true or not, and finally makes the submarine escape. 18. Spider and armored biologists have found that the strength of spider silk is five times that of steel wire with the same volume. Inspired by this, a technology company in Cambridge, England, tried to make high-strength fibers similar to spider silk. Composite materials made of this fiber can be used as structural materials such as bulletproof vests, bulletproof vehicles, tanks and armored vehicles. 19. Giraffes and "anti-Dutch clothing" giraffes are the tallest animals in the world at present. The distance between their brains and hearts is about 3 meters, and blood is sent to their brains by blood pressure as high as 160~260 mm Hg. According to general analysis, when giraffes bow their heads to drink water, their brains are lower than their hearts, and a large amount of blood will flood into their brains, which will increase their blood pressure even more, so giraffes will die of diseases such as cerebral congestion or blood vessel rupture when drinking water. But the giraffe's thick skin tightly binds blood vessels, which limits blood pressure. Aircraft designers and aviation biologists have designed a novel "anti-load suit" based on the principle of giraffe skin, thus solving the pain caused by cerebral ischemia when ultra-high-speed fighter pilots suddenly accelerate their climb. There is a device in this "anti-load suit", which can compress air when the plane accelerates, and it can also exert corresponding pressure on blood vessels, which is better than the thick skin of giraffe. 20. The "whale back effect" between whales and submarines. Contemporary nuclear submarines can dive under the ice for a long time, but if they launch missiles under the ice, they must break the ice and float, which encounters mechanical problems. Diving experts are inspired by the fact that whales break ice and breathe every 10 minute. In terms of the podium coaming and superstructure protruding from the top of the submarine, they strengthened the material strength, simulated the whale back, and truly achieved the "whale back effect" when breaking the ice. 2 1. Temperature control system for butterflies and satellites. Satellites that run in space when exposed to sunlight ...
