Sir Everest, who measured the height of Mount Everest, the highest peak in the world, did not climb Mount Everest, but he discovered the height of Mount Everest. How will it be? In the same way, scientists measure the depth without going deep into the sea. How will it be? Many of us have many such questions.
Recently now, the government of Nepal itself has started measuring the height of Mount Everest. Let's do something fun here. We used to study in school. When Halesi came to the market, Madhes traders used to make jerry too. We used to call it jerry. In the whole market, our attention went only to that Jerry. It was natural for our attention to go to Jerry because it was cute and sweet, but one question puzzled him. That jerry can is closed, but where does the shop get so much sweet stuff like honey? Now it is known that sugar is mixed in the wet flour at the beginning. This is a common question in our life.
Scientists are saying that the weight of the planets which are far away from the earth is this much. Do you know how they are measuring the weight of these planets without going there and without touching them? How do they measure the weight of the planets?
How do scientists measure the weight of the Planet?
The formula for measuring the weight of the planets was discovered by the scientist Sir Isaac Newton. Based on the formula invented by him, scientists have been able to find out the weight of all the planets starting from the sun. For this, Newton's law of gravity should be used. All planets have the magnetic ability, i.e. they have the power to attract and pull others toward them. As much as the pulling and pushing power is, the mass of the planet is also the same, i.e. its weight is also the same.
Like if you can find out the weight of the earth, you have to know its magnetic attraction. After knowing the magnetic potential, it is known that the weight of the earth is equal to that. How to know how much the magnetic attraction of a planet that is so far away is? Such a question also arises. For that, we have to take the help of satellites sent by scientists from Earth. The scientists living on the earth know that the satellite that has reached the edge of any planet, how much power that planet has towards it. In this way, the weight of that planet is found out by scientists.
Interesting fact
- 4 billion years ago, 19% of Mars was covered by sea.
- These five planets Mercury, Venus, Mars, Jupiter and Saturn can be seen with the naked eye without using a telescope.
- As many as 22,000 different objects, including man-made satellites, are moving in the sky around the earth.
- All the planets are named after Roman Gods, but the Earth is not named after God.
- There is one day on Mercury equal to 59 days on Earth.
- There are more ants weight on earth than there are humans weight on earth.

What is Nanotechnology and What Can It Do?
We can measure land, We can measure the house, We can measure books, We can measure television, We can measure cars, and We can measure the height of a mountain and the length and width of a road. We can measure many things that we can see with our eyes and touch with our hands. We measure all these in feet, meters, kilometers, miles, etc. But can we measure the virus that gives us fever? No, we can't. Can we measure germs? No, we can't.
Can we measure the atom, the smallest unit of matter? No, we can't. However, nanotechnology has made it possible to measure all these. We can measure even very small things that cannot be seen by the eye using nanotechnology. It was invented by Nobel Prize-winning scientist Richard Feinman. He put forward the concept of the possibility of this technology in 1959. However, the work of popularizing the term nanotechnology was done in 1980 by K. Eric Drexler.
We can usually calculate up to centimeters and millimeters, that is, we can measure in centimeters and millimeters. Nanotechnology is the technology to measure even things as small as 1 billion times a meter. However, using nanotechnology, we can measure 25.4 million objects smaller than one inch. We can measure units 100,000 times smaller than the pages of the books we read. Using nanotechnology, we can measure even the smallest unit of matter, the atom.
Anything on this earth can be measured using nanotechnology. The use of nanotechnology will be very useful in all fields of science. Its use in all fields such as physics, chemistry, biology, and engineering has made it possible to do a lot of work.
In these fields of science, even units as small as a millionth of an inch are important, and nanotechnology can solve these problems. For example, if we know how a virus attacks the body and what its shape is, we can know exactly how to cure it or what kind of medicine should be used to cure it. Now, whatever progress is being made in the field of science, the contribution of nanotechnology has been high. By using this technology, the products produced by the industrialists can be made many times more useful. Useful work for people can be done by using this technology in medicine, transportation, and agriculture.
Interesting facts about the Nanotechnology
- According to an analysis, the products produced by industrialists using nano-materials had a turnover of 1.3 trillion dollars in the world market in 2013.
- By using nano-particles i.e. very fine particles, the blood flow from the veins to the heart and lungs can be opened if it is blocked.
- Scientists at UC San Diego have created nano-particles, or tiny molecules, that glow inside the body. It can easily detect tumors and wounds in body parts.
- A group of scientists at USC is manufacturing such nanoparticles, which will now help transplant the brain.
- Zhong Lin Wang has created such a shirt using nanotechnology, which can charge a mobile phone and a blood pressure measuring device with the heartbeat.
