Who discovered electricity? Who invented the submarine?

Electricity was discovered scientifically by the English physicist William Gilbert in the year 1600.

In my village, Some year ago that is, in the year 2021, the electric light was lit. Otherwise, the bulb was lit by solar panels. Before that, wicks were lit by making from kerosene. Before that, the seeds of Kadam fruit were taken in sinks and lit as wicks. Before that, wood was burned. Before that, only firewood was used. This is how my village was illuminated at night.

Electricity is a very important thing in today's world. Humans are not complete without electricity. So when electricity was reached in our village all people of the village become very happy. The day of lighting the bulb is celebrated with great joy in our village. The program is done. There were various programs done like dancing and singing.

Now let's talk about how such a great thing was invented in this world & Who discovered or who is the founder of this electricity that makes light in the dark and brings happiness to people and what is electricity? Let's talk about this.

Who discovered electricity?

In today's world, nothing can be done without electricity. Not only this, everything that is happening stops in this world without electricity, The factory does not run because the machines are running on electricity. The office does not work because the computer is running on electricity.

The plane does not fly because the airport tower that instructs it to take off and land is powered by electricity. Even if there is no electricity, the wind blows and the sun shines. The river keeps flowing The birds continue to sing. However, the human world comes to a standstill.

This electricity, i.e. electricity, has been there ever since the universe was created Our ancient ancestors knew that there is electricity because they saw the light that shone due to the friction of the clouds when it rained. However, Electricity was discovered scientifically by the English physicist William Gilbert in the year 1600. It was named after the Greek word electron.

When two stones or an object rub together, the spark that comes out is called an electron in Greek. Some consider Benjamin Franklin to be the inventor of electricity, but he did such an experiment only in the year 1752. And Alessandro Volt developed the technology that can burn that electricity through batteries in the year 1800. Nowadays, the voltage of electricity is measured by the name of Volt.

Interesting facts
In 2005, an Australian wearing a nylon jacket and woolen shorts produced 40,000 volts of electricity that burned carpets and melted plastic.
Benjamin Harrison, the 23rd President of the United States, is the first American President, who used the electric light in the White House, but he never touched the switch because of the current.
In 1950, scientists at Tulane University discovered the center of the brain that experiences pleasure. And they sent electricity to that part of a woman's brain for 30 minutes, so that the woman felt the same pleasure she felt when having sex with her husband.
Japanese professor discovered that if you turn off the electricity and cultivate in the dark, the size of the mushroom will double. That is the reason why nowadays mushroom growers cover the mushroom tunnel with black plastic and keep it dark.

Who invented the submarine?

The first person who build a submarine was Cornelius van Dreidel

I will tell you something interesting that I found on the internet. the knowledge that is being said face to face in Kirati is Mundum, This is a priceless intellectual heritage of Nepal. Mundum also tells about where Kirati's ancestors came from. In that order, there is a description that they spread towards the eastern hills of Nepal after crossing the Saptakoshi. But, how they can cross such a huge Saptakoshi River?

According to Mundum, Kirati's ancestors have been sailing Saptakoshi by boat. And people started using boats 50,000 years ago. This is how the human ancestors climbed from the Indian Ocean to Australia. That is why they have spread from one place to another even though there is no bridge.

However, a boat cannot be used on a steep river, in such a way, they used to swim by hanging on the waves or by holding on to the branches of the trees. The history of modern ships and submarines started with such boats and waves.

In different parts of the world, there are various types of submarines that can go underwater. A picture of a submarine made by Leonardo da Vinci has been found among the old submarines. Similarly, British mathematician William Bourne made a diagram of a submarine in 1570. However, both of them did not make submarines, they only made pictures.

The first person who build a submarine was Cornelius van Dreidel. He made the first submarine in 1620 by wrapping a wooden boat with leather. This submarine could stay underwater for three hours. An arrangement was made to allow oxygen to enter the submarine through a tube for breathing underwater.

The first person who makes a submarine for military purposes is David Bussell of America. In 1776, he built a single-deck submarine out of wood. Now that it has become such a great, heavy, and amazing submarine, what to talk about?

Interesting facts about submarine
L. Ron Hubbard claimed that he fought alone for 68 hours against Japanese submarines during the First World War, but later research revealed that no submarine had reached the area he said.
Scientists have proved that sound can be heard better in water than in air and can reach far. AFA Sonar has created the loudest submarine ever built by man, with a sound of over 200 decibels. When the submarine reaches the sea all fishes of the sea escape.
The British submarine HMS Artful can stay underwater for 25 years. No need to keep coming out of the sea to get oxygen.
Most submarines are yellow in color because the only color visible when going deep is yellow.
It takes a man 1000 years to build submarine like Virginia.
