Essay on wonder of science(advantage of science)
Answers
Answer:
Introduction – Today we are living in the Science era (युग). We solve all difficult problems easily with the help of Science.
Science has been a Necessity of the present era. with the help of science we can solve the all difficult Problems easily. This is the revolution trough science in all fields. Science also a major contribution in the Agriculture.
2- Advantages of Science – Science has given us a lot of things as a gift , like today we can fly in the sky. We can easily travel long distances with the different types of transports. Train , Buses, Car are the greatest invention of Science. To day we are living in the right way.
3- Disadvantages of Science – We have got many benefits from the science , so we have also suffered a lot due to science . Our environment has been polluted today due to science.
Our revers which are called Lifeline Polluted by the west water of Factories. Birds are died to harmful rays. emanating from the mobile tower area facing a lot of loss.

4- Means of Transport – Science has provided such means for transport with the help of science of which we can send our goods to any country or any place today and can also travel own.
Today many people travel in train and long distance we can easily travel in the same way , we travel long distances by flying in the Aeroplane in addition to this . we can travel easily by everyone motercycle cars etc.
5- Means of communication – Science has Provided us with useful things such as mobile phones telephones etc. To stay connected.
So that we can connect and talk to anyone from anywhere it is a great achievement today. we can reach any corner of the world. we can talk to anyone.
6- Computer- Computer, Science is a very good achievement that science has given us. Computer solve complicated mathematical works easily. Computers are used by everyone from school to colleges and the scientist. Children are in school in today modern era. Computers laptops are using for reading in the school.
7- Electricity – Electricity is a big invention of science and the great achievement . Earlier humans used to live in darkness but after the invention of electricity today every house has light there is light on the road cooler fans all we are able to use.
8- Conclusion – Science has a made many inventions which are beneficial for us so it is harmful as well so human beings should use all the inventions given with science very carefully becouse it is also having side effects on mankind hence all inventions.
Science is an ongoing search for truth—a perpetual struggle to discover how the universe works that goes back to the earliest civilizations. Driven by human curiosity, it has relied on reasoning, observation, and experiment. The best known of the ancient Greek philosophers, Aristotle, wrote widely on scientific subjects and laid foundations for much of the work that has followed. He was a good observer of nature, but he relied entirely on thought and argument, and did no experiments. As a result, he got a number of things wrong. He asserted that big objects fall faster than little ones, for example, and that if one object had twice the weight of another, it would fall twice as fast. Although this is mistaken, no one doubted it until the Italian astronomer Galileo Galilei disproved the idea in 1590. While it may seem obvious today that a good scientist must rely on empirical evidence, this was not always apparent.
The scientific method
A logical system for the scientific process was first put forward by the English philosopher Francis Bacon in the early 17th century. Building on the work of the Arab scientist Alhazen 600 years earlier, and soon
to be reinforced by the French philosopher René Descartes, Bacon’s scientific method requires scientists to make observations, form a theory to explain what is going on, and then conduct an experiment to see whether the theory works. If it seems to be true, then the results may be sent out for peer review, in which people working in the same or a similar field are invited to pick holes in the argument, and so falsify the theory, or to repeat the experiment to make sure that the results are correct.
"All truths are easy to understand once they are discovered; the point is to discover them." Galileo Galilei
The first scientists
The first philosophers with a scientific outlook were active in the ancient Greek world during the 6th and 5th centuries BCE. Thales of Miletus predicted an eclipse of the Sun in 585 BCE; Pythagoras set up a mathematical school in what is now southern Italy 50 years later, and Xenophanes, after finding seashells on a mountain, reasoned that the whole Earth must at one time have been covered by sea. In Sicily in the 4th century BCE, Empedocles asserted that earth, air, fire, and water are the “fourfold roots of everything.” He also took his followers up to the volcanic crater of Mt. Etna and jumped in, apparently to show he was immortal—and as a result we remember him to this day.
Stargazers
Meanwhile, in India, China, and the Mediterranean, people tried to make sense of the movements of the heavenly bodies. They made star maps—partly as navigational aids—and named stars and groups of stars. They also noted that a few traced irregular paths when viewed against the “fixed stars.” The Greeks called these wandering stars “planets.” The Chinese spotted Halley’s comet in 240 BCE and, in 1054, a supernova that is now known as the Crab Nebula.
Elements, atoms, evolution
In the 18th century, French chemist Antoine Lavoisier discovered the role of oxygen in combustion, discrediting the old theory of phlogiston. Soon a host of new gases and their properties were being investigated. Thinking about the gases in the atmosphere led British meteorologist John Dalton to suggest that each element consisted of unique atoms, and propose the idea of atomic weights. Then German chemist August Kekulé developed the basis of molecular structure, while Russian inventor Dmitri Mendeleev laid out the first generally accepted periodic table of the elements.
Secrets of life
In biology, chromosomes were shown to be the basis of inheritance and the chemical structure of DNA was decoded. Just 40 years later this led to the human genome project, which seemed a daunting task in prospect, and yet, aided by computing, got faster and faster as it progressed. DNA sequencing is now an almost routine laboratory operation, gene therapy has moved from a hope into reality, and the first mammal has been cloned. As today’s scientists build on these and other achievements, the relentless search for the truth continues. It seems likely that there will always be more questions than answers, but future discoveries will surely continue to amaze.
