Essay On World Of Science

“The intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural world through observation and experiment.” This is what comes when I type, “What is science?” on the internet. The world of science revolves around three main topics, physics, chemistry, and biology. People who study these topics are called scientists, which can be narrowed down depending on the topic they are studying about. These scientists have changed the world in many ways, such as Newton and Einstein. Scientists have also dedicated their life to science, some even sacrificing theirs. What do scientists exactly do while they are researching or studying? They observe objects and their movement and try to

Scientists like Rutherford and Galileo have also made notable changes to people’s thoughts. Rutherford founded the nucleus, and Galileo found out that the Earth was revolving around the sun, not the opposite.

Almost all scientists have provided us with reasons why things happen, and how the Earth exactly works. Science has told us how much food to eat and how much water to drink, and what we should eat and drink. Scientists have provided entertainment through televisions, movies, computers, and many other things. Science has been so influential in so many ways that only natural things would have existed if science did not
