Question 2: What other interesting inventions do you know? The inventor of the telephone was Alexander, an Englishman? Bell. Bell applied for the telephone patent in March 1876.
Question 3: What's interesting about China's invention? He invented a wooden bird that can fly in the sky, just like Lu Ban in the Warring States Period. During the Western Han Dynasty, someone invented a life-size wooden robot that could dance automatically. During the Three Kingdoms period, Ma Jun of Wei invented a truly functional mechanical compass based on the legendary "Yellow Emperor Compass". The villain on the roof was driven by gears and always faced south. The weapon "Dragon Out of the Water" invented in Song Dynasty, which uses built-in fuel to propel Mulong forward, is the earliest rocket in the world. The Ming dynasty weapon "Shenhuo Feicrow" shot into the sky with a rocket, fell parabolically and exploded in the enemy line, which coincides with the principle of modern tactical missiles.
Question 4: What are the interesting inventions of mankind? All human inventions are interesting: movable type printing was invented because I was too lazy to write word by word, weeding machine was invented because I was too lazy to pull weeds one by one, washing machine was invented because I was too lazy to walk step by step, elevator was invented because I was too lazy to wake people up, alarm clock was invented because I was too lazy to tell you hundreds of times, and tape recorder was invented because I was too lazy to kill one by one, so Qian Xuesen was born. . . . . Invention is the invention of lazy people!
Question 5: Do you know any other interesting inventions? Light bulb.
Question 6: What are the interesting inventions? The tortoise carries a tortoise: a tank with a rotating turret.
Birds fly in the sky: they make all kinds of flying machines.
Bees build nests: various hexagonal honeycomb structural plates.
Every dragonfly has a slightly heavier point at the end of its wing than its surroundings, which is the key to prevent its wings from shaking. Aircraft designers study the flight methods of flies, mosquitoes, bees, etc. , and created many new aircraft with various excellent performances.
Whale: the shape is ideal "streamline", and "streamline" has the least resistance in water. Later, engineers imitated the shape of whales, improved the design of the hull and greatly increased the speed of the ship at the stern.
Eggshell: it can evenly distribute the pressure to all parts of the eggshell. According to the characteristics of this "thin shell structure", architects have designed many buildings that are both light and material-saving.
Kangaroo: A jumping cross-country car.
Shell: A tank with a solid shell ...
Fish swimming in the water: learned to swim and invented the submarine.
One-piece shark suit: The first generation shark suit imitates the shark's skin, and some rough dentate protrusions are designed on the swimsuit to effectively guide the water flow, tighten the body and avoid the vibration of the skin and muscles. The second generation of shark clothing has added some new highlights, adding a material called "elastic skin", which can reduce people's resistance in water by 4%. In addition, two accessories have been added, and the bumper made of titanium silicone attached to the forearm can make athletes swim more easily; Vibration control systems attached to the chest and shoulders can help guide the water flow.
Let the blind see the light: After implanting tiny bionic retina, three blind patients not only saw flashing or moving light spots, but even successfully distinguished cups and plates with their eyes.
Synthetic spider silk: Spider silk contains a fibrin similar to keratin in hair and horns. This protein began to become tough after it was secreted. By carefully balancing the moisture content, spiders and silkworms can prevent fibrin from curing too fast.

Fly olfactory device: small gas analyzer.
From fireflies to artificial luminescence. Because this lamp has no power supply and does not produce magnetic field, it can be used to clear magnetic mines under the irradiation of biological light source.
Electric fish and volt batteries. Through the anatomical study of the electric fish, it is found that there is a strange power generation organ in the electric fish. Italian physicist Volt designed the world's earliest voltaic battery based on electric fish power generation organs.
Jellyfish ears: the storm forecaster of jellyfish ears, and the simulation is quite accurate.
Question 7: What are the interesting inventions in the world? 1. Electronic pet dog.
Do people remember electronic pets? At present, Bandai Company has recently designed a new toy software, which can become a typical virtual electronic pet. People only need to download the TechPet mobile phone application software from and feed the electronic pet dog through the touch screen.
2. Google Glass
Simply put, this is a computer built into the glasses frame. This pair of glasses is equipped with a half-inch (1.3cm) display. You can use it to take and share photos, video chat, check appointments, visit maps and the Internet. By 20 14, consumers can buy Google Glass.
3, 3D smart printer
Download or create a new pattern, and then click the print button. This 3D printer, which occupies a small area, can extrude ultra-thin plastic, and print out physical objects layer by layer, as many copies as you want. Compared with the model before MakerBot, the latest Replicator2 is more efficient, prints more accurately, and its software is easier to operate, and you don't need to assemble the machine. With Replicator2, anyone can open a small factory at home.
4, bamboo tube iphone speaker
This kind of bamboo tube speaker can amplify the sound of iphone and enhance the three-dimensional sense without external power supply.
5. high-speed swimsuit
In June+10, 5438, the first Winging World Championship was held in China. The pilot wearing a "bat suit" jumped off a 5,000-foot (1 1,500-meter) cliff, glided over a valley, finally opened his parachute and landed on the ground, flying three-quarters of a mile (more than one kilometer) in 30 seconds. At present, only 20 people are eligible to participate in the competition. Julian from South Africa? JulianBoulle won the championship and set a world record. His time is 23.4438+0 seconds.
6, water spray backpack
The water-jet backpack designed by the French inventor can not only make people jump 30 feet into the air from the water, but also dive into the water like a dolphin.
7.quantum invisibility cloak
The U.S. military recently invested in the development of a "quantum invisibility" material, which can bend the light waves on the cover, thus making people achieve the effect of an invisibility cloak similar to that of Harry Potter. This material is called "Quantum Invisible" camouflage materials, which bends the light waves around the human body, thus making the person who covers the cloth completely invisible.
8, automatic pneumatic tires
When the tire pressure is too low, this Goodyear tire can detect it, and the built-in pressure detector will automatically turn on when the tire pressure is too low, allowing air to enter a pump pipe. When the wheel rotates, the compressed part at the bottom of the tire exhausts air from the pump pipe. When the air pressure reaches the optimal state, the pressure controller is closed.
9, solar bonsai charger
French designers have recently designed an "electronic bonsai". Its leaves are composed of 27 solar panels, which can charge electronic devices such as mobile phones. In sunny conditions, the mobile phone can be fully charged within 4 hours.
10, small artificial indoor cloud
This is not a PS-processed image. Dutch artist Bendernut-Smild recently invented how to make white clouds indoors. This requires precise and meticulous planning and design: temperature, humidity and light must be just right. When the preparation conditions are available, Smild uses a smoke machine to make this indoor artificial cloud. It lasts for a short time, but it is beautiful and can move wonderfully.
