You look at every electronics thing in your house, such as your home TV, desktop computer, fan, lamp. Have you ever wondered, these important electronics things in your house would never work if your house did not have electricity.
So, because we have electricity, we can run these things very easily. This electricity has accelerated modern science. Alessandro Volta invented the first practical method of electricity. 1831 is marked as the year of the advent of electricity. On the other hand, the basic concept of electricity was discovered by the British scientist Michael Faraday.
Although the idea of electricity comes much earlier. In 600 BC, the ancient Greeks discovered that amber (known as the resin of fossilized trees) was attracted by rubbing fur on it. Originally the ancient Greeks discovered static electricity at that time.
In 1600, the English scientist William Gilbert used the Latin word Electricus in some of his research papers. Presumably, the word ‘Electricus’ is the name given to the name ‘Electricity’ today.
However, many consider Benjamin Franklin to be the inventor of electricity. Because of this, Benjamin Franklin discovered the idea that lightning is a form of electricity. In 1752, in stormy weather, Franklin tried to fly a kite with an iron key. Later the lightning struck his kite and Ben was also slightly injured by the lightning. However, nothing serious happened to her.
After that, Michael Faraday, George Ohm, and many other scientists did a lot of research on electricity. As a result of their research, electricity can be used in different ways today.
This oldest discovery has revolutionized our travels. The earliest known wheel of archeological excavations was made in ancient Mesopotamia in 3000 BC. Since then it has been used as an integral part of every modern vehicle with millions of times new and innovative designs of wheels.
The invention of the engine is one of the major inventions that have played a major role in advancing civilization. The rapid movement from one place to another and the subsequent arrival of rail and car are intimately involved with the invention of the engine.
The word engine comes from the Old French word “engin” and the Latin word “ingenium”. We know that energy is not created or destroyed, it can only be taken from one form to another. An engine is a device that normally converts any other form of energy into mechanical energy.
In 1772, English scientist Thomas Newman discovered the steam pump, which was used to draw water from mines. There has been no such attempt before, but it is not. However, the name of the man who started the Industrial Revolution is James Watt. He was the first to improve the steam engine invented by Thomas Newman. For the benefit of James Watt, human civilization gets a steam engine. And this is the beginning of the industrial revolution. The main point of this discovery was that the pressure created by the steam pushes a piston and the piston is connected to the crankshaft by means of a connecting rod. This is how speed is obtained. At that time, steam-powered trains were the first to run with steam engines. In various European countries, the industrial revolution took place with the help of steam engines. Speed comes in human life. And production also increases manifold.
The first electric battery was invented by the Italian physicist and chemist Alessandro Volta. He is hailed as the first battery inventor in the eighteenth century. Production of electric batteries began in 1802 by the chemist William Cruickshank. On the other hand, the first rechargeable battery was discovered by the French physicist Gaston Plante in 1859.
Airplane also called airplanes or aircraft. An airplane is a type of aircraft that is heavier than air but capable of flying. It is used to transport passengers and goods. The name airplane combines the words fly and ship. The invention of the airplane is one of the most exciting discoveries in changing the world. The history of the invention of the airplane is basically a story of intense competition. At one end of the conflict was Wilbur Wright and his brother Orville Wright, the pioneers of airplane discovery, and at the other end was Glenn Curtiss, a motorcycle manufacturer. The result of this bitter competition, plagued by various dangers and accidents, changed the history of the world in an unimaginable way.
We have an article on the history of airplane discovery. You can read it if you want.
One of the great discoveries of science is the rocket. Which man has delivered from earth to space.
Dr. Robert Hutchings Goddard (1882-1945) is considered the father of modern rocket propulsion. A physicist of great insight, Goddard also had a unique genius for invention. It is in memory of this brilliant scientist that NASA’s Goddard Space Flight Center in Greenbelt, Maryland, was established on May 1, 1959.
By 1926, Goddard had constructed and successfully tested the first rocket using liquid fuel. Indeed, the flight of Goddard’s rocket on March 16, 1926, at Auburn, Massachusetts, was as significant to history as that of the Wright brothers at Kitty Hawk.
The compass was originally invented for spiritual and naval purposes. It was probably discovered by the Chinese in 1050 BC. It was originally made with attractive materials; It had all the features of a magnet. In 1825, the inventor of the electromagnet led the development of modern compasses. Despite having GPS technology, this compass has played a revolutionary role in taking analog navigation and science on a new level.
Bulb or lamp
Though Thomas Edison is usually credited with the invention of the light bulb, the famous American inventor wasn’t the only one who contributed to the development of this revolutionary technology. Many other notable figures are also remembered for their work with electric batteries, lamps, and the creation of the first incandescent bulbs.
This discovery marked the beginning of commercially manufactured light bulbs and in 1880, Thomas Edison’s company, Edison Electric Light Company begin marketing its new product.
The Internet has changed the world and changed our lives. In the present age, the internet is very much involved with us.
No one is behind the invention of the Internet like the bulb or the telephone. It was introduced in the United States in 1950 through the efforts of various scientists over a long period of time. Since the mid-1990s, the Internet has revolutionized current technology. Initially, the use of electronic mail or email increased at a huge rate. Google’s use of the Internet in 2000 increased both popularity and popularity. Google opens a new door on the Internet.
The computer is a device without which we cannot imagine today. Computers are now used in all kinds of organizations. Everything from listening to music, watching movies to technology can be done with this computer.
Basically, there is no single inventor of the computer. Because, in the course of time, many scientists have played a role in the invention of the computer. Yet Charles Babbage is considered to be the first inventor of the computer.
The modern form of telephone is mobile phone. The telephone, invented by Alexander Graham Bell before the mobile phone, was the only modern means of long-distance communication.
The invention of the mobile phone is not too long ago. The invention of the mobile phone is based on the idea of solving all the disadvantages of using the telephone. For example, it has a telephone and it cannot be carried from one place to another. And to solve this problem, an American researcher named Martin Cooper invented a mobile phone.
In 1973, Martin Cooper introduced mobile phone communication. At the time, Martin Cooper was a researcher and executive at Motorola, a well-known American company.
There are 5.11 billion unique mobile users worldwide in 2019, and 2.71 billion of them use smartphones.
100 million people have started using smartphones in the past year.
52% of the world’s population are mobile internet users.
There will be 2.87 billion smartphone users worldwide in 2020.
In today’s world, overuse of Internet technology has led to a decline in the use of paper and paper newspapers or books. Because, now any information can be exchanged through email in the office court. However, before the Internet, the printing press was the most important tool for exchanging information and books and magazines.
The inventor of the printing press was Johannes Gutenberg of Germany. Gutenberg is thought to have started using the first printing press around 1450.
The camera is undoubtedly one of the best inventions of human creation. The camera first turns the corner of the media world or the world of entertainment; The invention is television. In just a few decades, radio-centric people have turned to television.
Concrete is an important part of all the buildings we see today. The importance of this man-made concrete may no longer be overemphasized. However, the use of concrete dates back thousands of years.
Concrete is thought to have been used as early as 6500 BC. And 3000 years ago, the Egyptians first built a pyramid using concrete. However, cement is an important component in making concrete. The first use of this cement was in 1300 BC. Due to cement, concrete becomes more rigid and durable.
Steel is essential for the construction of large buildings or skyscrapers. Many people think that steel is iron. That is, think of synonyms. However, steel or iron is not one thing.
Because iron is a natural element. That is, iron is a mineral. Steel, on the other hand, is steel made by mixing iron and other elements, including carbon. And this steel is much harder than iron. Although steel was made in various ways in the 18th century, its use began to increase exponentially in the mid-19th century.
There have been many advances in medicine since the invention of the X-ray machine. And it was discovered by William Rন্টntgen. He discovered it in 1895. Since the color of the dye ray is much less than that of light, this ray of vision does not create a feeling. There is a strange story behind the discovery of X-rays.
He made it open to human service. He did not receive any patents. He did not know about this ray discovered by Ranjan. And so, in the language of physics, he named this ray X-Ray because an unknown quantity is expressed with the letter X.
Although the German inventor pioneered the modern car in the 18th century, the car was not widely available commercially at the time. Henry Ford later developed a standardized commercial vehicle production strategy through his Ford Company. At the present time this modern vehicle has become an index of economic usage.
