First place: Leonardo da Vinci (Italy)
The most famous invention: calculator
Mentioned Leonardo da Vinci and When he invented something, you'd better ask the question: "What was not invented by him?" Because he invented too many things. There are design drawings of many things in Leonardo da Vinci's work diary, but among them The most noteworthy thing is the design of the calculator. Just imagine what science would be like without simple and complex mathematical operations.
Leonardo Da Vinci can be called the founder of the Renaissance. He can draw (such as the masterpiece "Mona Lisa"), he can sculpt and invent. His diary, which still fascinates the world, depicts and outlines many things from the human body to helicopters and tanks.
The coolest Facts: Leonardo da Vinci’s diary is more than 13,000 pages long and is still influencing scientific research. In 2005, a British surgeon also used the method designed by da Vinci to perform heart repair surgery. This fact itself is surprising. , you would be simply surprised if you knew that Leonardo da Vinci didn’t even have the slightest idea of ??the working mechanism of the human circulatory system.
Second place: Nikola Tesla (USA) < /p>
The most famous invention: radio
Although Nikola Tesla was not recognized for this during his lifetime, the U.S. Federal Supreme Court finally affirmed his patent application and confirmed that it was him It was not Marconi who invented radio.
Tesla may have been born to be unconventional. Although he invented a power transmission method called "alternating current" that is still in use today, in fact, the focus of his research was On the theoretical application of electricity (unfortunately, many research results still remain on the drawing board). It was Tesla, who always made his own experimental equipment (such as the famous Tesla coil used to gather electrical energy), who proposed the scope Covering a range of ideas, from The FBI really couldn't see anything interesting, so President Hoover had to order Tesla's scientific research materials to be taken away and declared "top secret".
Third place: Alexander Dro Volta (Italy)
The most famous invention: the battery
Although Volta did not discover electricity, he came up with a good idea to carry electricity. You need to know "Volt Battery" is the forerunner of modern batteries.
Volt has been working on electricity throughout his career. In the early days, he invented the electrifying disk (that is, a single-plate capacitor with a single charge), and a year later he devoted himself to the closed chamber Gas ignition power generation experiment, during which he discovered biogas (methane), a gas commonly used in households today. However, what really made it famous was the "voltaic battery", which is actually a pile of zinc and copper sheets interacting with each other. Arrangement, plus a cloth soaked in salt water between two metal sheets to enhance conductivity. But it is this crude battery that shows the world the secret of how to use metal-chemical combinations to generate electricity.
< p>Coolest fact: In 1810, Napoleon awarded the great Italian inventor the title of Count Volta. But the honor did not stop there. In 1881, his name was adopted as the unit of voltage "volt".Fourth place: Alexander Bell (UK)
The most famous invention: the telephone
“Can you hear me?”
"Yes!"
We can hear each other speak, thanks to Alexander Bell's invention of the telephone.
There are so many telephone providers, but it was Alexander Bell who invented the telephone. Bell's credit created the world's first (and most powerful) telephone company, the Bell Telephone Company. Bell was not just a one-man wizard. His research ideas involved air conditioning (he actually worked on it in his own house).
Coolest Fact: Alexander Bell or the World The inventor of the first metal detector in the world, he assembled the device to find the bullet in the body of US President James Garfield. As a result, the detector could work, but it could not determine the location of the bullet because the inspection was added President Field was lying on a metal frame bed.
Fifth place: Isaac Newton
(UK)
The most famous invention: calculus
If you have gone through all the trouble of taking advanced mathematics courses, you may not be Sir Isaac Newton is an ardent admirer of , because the problem you're encountering is basically his fault - he invented calculus.
If you study physics now, whether it's about gravity (an apple falling from a tree) The story of up and down, whether true or false, is indeed a powerful illustration), or the principles of light and optics, you have to start with the research results of Sir Isaac Newton. Newton was the first to propose that "light is composed of particles" ", this principle allowed him to develop the reflecting telescope (now named after him). In addition, Newton also made contributions to the research on the principles of sound and heat.
The coolest fact: People are easy to Think that scientists are a group of laboratory "rats" who don't care about the world, but Newton is an exception: he served as a judge for the King of England for nearly two years, and was engaged in the business of executing counterfeiters. Towards the end of his legal career , there are still 10 criminals waiting to be executed.
Sixth place: Howard Hughes (USA)
The most famous invention: improved aircraft design
Howard Hughes did not invent the airplane. As the "father of Trans World Airlines (TWA)", he mainly wrote books about airlines. Although TWA is history now, the aviation industry is thanks to Howard Hughes Hughes thrived.
He once proposed a series of innovative designs for passenger aircraft. For example, he redesigned the "H-1" and made retractable landing gear, connecting rods and connectors, etc. It is retracted inside the fuselage, thereby reducing the air resistance during flight. This innovative improvement had an impact on a series of fighter designs during World War II.
To say that Howard Hughes is a weirdo is to disparage him. He was born into a family of famous inventors. The oil well drill bit invented by his father, Hughes Sr., allowed oil production equipment to extract resources that were previously inaccessible to people. Howard Hughes lived in low-key seclusion in his later years, but when he was young and prosperous, he conquered aviation. A big shot in the world and Hollywood. Whether he was developing an amphibious aircraft or trying to meet Hollywood stars Katharine Hepburn or Bette Davis, he always went his own way.
The coolest fact: In 1972, Hughes Employed by the CIA to cover a CIA operation. This operation, codenamed "Project Jennifer", was intended to salvage a Soviet submarine that sank in the waters of Hawaii. The effect of this operation was limited. In 1975, a bandit Some of Hughes' secret information was taken away, and his relationship with the CIA was revealed.
Seventh place: Benjamin Franklin (USA)
The most famous invention: double Focal length glasses
We all know that reading is fundamental, but seeing is a prerequisite. Thanks to the bifocal glasses invented by Benjamin Franklin, even people with vision below 20/20 can browse the website Web page. While he was writing "The Chronicle of Poor Richard," helping the United States win recognition from France (a move that turned the tide of the American Revolution), and wooing women everywhere, Franklin still made important contributions to science. Contribution. Many of us may remember the scene in social studies courses depicting him flying a kite in a storm. This experiment taught Franklin a lot about electricity and also brought us the lightning rod.
The coolest Fact: Inventors and "stallions" (men who love to woo women) don't tend to be associated with the same person, but Benjamin Franklin was an exception. He was the most wooing man of his era. And his good popularity among French women is indeed beneficial to the American cause.
Eighth place: James Watt (UK)
The most famous invention: improved steam engine
p>Today we no longer regard steam as the main energy source, but back in the early days of the Industrial Revolution, steam was in the limelight. James Watt spent a lot of time improving the steam engine and driving the world forward. < /p>
Although Watt did not invent the steam engine, he made the steam engine work for people. In fact, it was Watt’s innovation and improvement that caused a major change in the world from agriculture to industry. In addition to the power and machinery In addition to making such great contributions, Watt also invented the rotating machine and a device called the "flying ball" that can automatically adjust the speed of the machine.
The coolest fact: the unit of power "Watt" Just in his name
Named after, he has always been recognized as the world's greatest engineer.
Ninth place: Johannes Gutenberg (Germany)
The most famous invention: modern printing Technique
Johannes Gutenberg was going to put all the little things together and make a movable type printing press. Before you realize that his printing technology could start an information revolution like this Before the fact, you feel that his idea seems a little not so great.
None of us know who wrote the Bible, but we know the name of its publisher: Gutenberg. That’s right, The Chinese had used movable type printing for hundreds of years before, but Gutenberg was the first to print and publish the characters in books instead of silk books. This innovation made knowledge accessible to a wider range of people, thus giving birth to the " "The Age of Enlightenment". As an inventor, Gutenberg was one of the best, but as a businessman, he was unlucky. His printing technology changed the world, but it did not make him rich, and he was in a lawsuit against his own investors. , he even lost the right to invent this technology.
The coolest fact: In the plight of debt, Gutenberg spent his later years by "working" for the Archbishop of Mainz. The Archbishop Provide him with room and board to help him get rid of his bad drinking habit.
Tenth place: Thomas Edison (USA)
The most famous invention: the light bulb
< p>No invention is more representative of innovation than the light bulb. In fact, Edison's invention had such a profound impact on the world that it was nicknamed the symbol of all great ideas.When people think of Edison It's easy to focus on the light bulb (an invention that he actually improved and made feasible), but his real intention was to energize the light bulb and make it shine. In 1882, Edison created the world's first electric transmission company to transmit electricity. Sent to 59 consumers in Manhattan. With the support of JP Morgan and the Vanderbilt family consortium, Edison also used his knowledge to provide the world with an early version of the stock machine.
Coolest Facts : In his later years, Edison became obsessed with a popular fashion diet, which was to drink only 1 pint of milk every 3 hours. Fortunately, Edison did not use his knowledge in the field of human life science.
