Top 10 Inventions that changed the world :-
Do you know how and when scientific discoveries and inventions changed the world? Now, In the 21st century, we are surrounded by so many technical and scientific stuff. Life without these scientific inventions becomes uncomfortable. We are living happily because we have everything in fingertip whether it is communication or entertainment.
Most of the people don’t know who is the inventor of such items and also when it was discovered? Today, I will tell about some historical inventions that changed the world totally. Here is the collection of Top 10 Inventions that changed the world and scientific discoveries.
10. Printing Press
Have you seen Printing Press Machine? Do you know who is the inventor of Printing Machine?
Different type of printing machines and methods have been developed over the years. Some modern methods of printing such as digital printing, laser printing, and screen printing have made printing faster and better.
Johannes Gutenberg was the inventor of Western printing. He invented the movable type printing technique in 1452. He used paper and oil based ink for printing. Gutenberg first successfully printed the book ‘The Gutenberg Bible’.
I know everyone like to ride cycling in the morning but most of the don’t know who is the inventor of Bicycle?
People used a bicycle for different purposes including recreation, exercise, and transportation according to their needs. Cycling is common throughout the world and especially in China, India, Brazil, South Korea, Japan, and The United States. Cycling is also an Olympic sport.
Baron Karl von Drais from Germany has invented a Bicycle in 1816. Early it was called the Lauf Maschine. It had a steering device and a handlebar built on the frame. The passenger had to sit and push himself by running on the ground. It was fully made of wood and had no pedals.
It is very enjoyable to drive an automobile and traveling too. But do you know who is the inventor of Automobiles?
Automobiles are self-propelled vehicles that run with the help of a motor or an engine. They usually run on petrol or diesel. Different types of automobiles include cars, vans, buses, and trucks. Mainly trucks are used in transporting goods.
Nicolas Joseph Cugnot invented the first self-propelled vehicle in 1769, a military tractor powered by a steam engine. He was a French engineer and mechanic. It was heavy and had two wheels at the back and one in the front. The French Army used to pull weapons at the speed of 4km/h. In 1770, Cugnot built a steam powered tricycle that could carry four passengers.
Microwaves are the electromagnetic radiations used to generating heat and are also used to communications. Longer microwaves like those used in a microwave oven are used to cook food. Shorter microwaves are used in communication and weather forecasts.
A Scottish scientist, James Clerk Maxwell has predicted the existence of microwaves in 1864. After 24 years, Heinrich Hertz demonstrated that Maxwell was right about the existence of microwaves in 1888. In 1894, the Indian scientist, J. C. Bose, publicly demonstrated the wireless control of a bell using microwaves.
6. Light Bulb
The electric light bulb is a glass bulb fitted with a wire filament, which glows when heated by electricity. The bulb contains a noble gas, which prevents the mental filament inside the bulb from evaporating. It is often called an incandescent bulb.
The American scientist, Thomas Alva Edison was the inventor of the first practical electric lamp in 1879. It had all the features of a modern light bulb and the first successful filament. The bulb could emit light for about 40 hours. After conducting many experiments, he made a bulb that could glow for over 1500 hours.
Just think if you do not have the clock to see the time then what will happen? Big thanks to the inventor of the clock.
Clocks, without a sounding mechanism, include timepiece, wristwatches, and other wall clocks. Sundials, water clocks, and atomic clocks are some of the other clocks. The word clock comes from the word clocca meaning ‘bell’. Some clocks, which have a striking system, ring a bell after an interval of time.
Sun clocks were primitive clocks were first used around 3500 BC by Egyptians. Obelisks were used as sundials. People could tell time using a sundial by observing the shadows formed on the ground. The primitive hourglass was invented around 3450 BC which used to tell time. Between 1280 and 1320, horologes or ancient clocks with bells were used to measure time.
Modern People crazy about taking selfies with the smartphone. What was the idea behind the photographs? Just take a look.
The first cameras could only take black and white still photographs. Later, cameras could capture an entire scene in color. However modern digital cameras can capture moving images along with the sound.
Joseph Nicephore Niepce was a French inventor and a pioneer in photography. Niepce is known for producing the first successful photograph in 1827. In 1824, he was able to produce long lasting images. He named his process heliography.
I think TV is the world’s best invention. What do you think? The perfect thing for entertainment and infotainment.
Television is one of the most important means of communication. The word ‘television’ means ‘far sight’. It brings pictures and sounds to homes from around the world. These images are relayed by communication satellites in the form of radio waves. Television sets have aerials that receive the waves and change them into moving pictures and sounds.
Vladimir Kozmich was a pioneer of television technology. In 1923, he invented a tube for television called iconoscope. John Logie Baird was the first to conceive the idea of electronic television. Baird carried out the first transmission of the object in motion using a mechanical television in 1924.
Philo Taylor Farnsworth is generally known as the father of electronic television. He is the inventor of the first fully electronic television system. He was the first person to make a working electronic image pickup device to transmit sign images using cathode ray tubes in 1927.
The machine which has big contribution to make world digital is Computer. What do you say?
A computer is a machine that stores and manipulates data. The earliest computers were big and bulky. They were very expensive, very slow, and had little memory. With each new invention, computers became more portable. By the mid-1970s, personal computers were invented.
Charles Babbage was an English computer scientist and mechanical engineer. In 1822, he designed the first mechanical computer and called it the ‘difference engine’. It was the size of a room and could compute tables of numbers. In 1830, Babbage designed his next machine and called it the ‘analytical engine’.
1. Blood Bank
I have put blood bank on Top position. why? Because blood bank saves humans life.
A blood bank is a place where blood is collected from donors, stored, and prepared for transfusion to recipients. Blood banks first separate the collected blood into its components and then prepare them for transfusion to patients. A blood bank may be a separate establishment or part of a laboratory or a hospital.
An American doctor Charles Drew has developed the technique of blood plasma preservation. He found that blood could be preserved longer this way. He also established the American Red Cross Blood Bank and the world’s first blood bank campaign called ‘Blood for Britain’. Charles Drew received the Spingarn Medal in 1944 for his contributions to medical science.
