What is Science? Complete Guide and its Evolution

Spread the love

Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.

Above all this blog will not just tell you about science definition but also talk about its application. Here we will see what are the components of the science definition of science.

Lets look what in it?

Science is the logical study of nature and whatever comes into it. The most punctual underlying foundations of science can be followed to Ancient Egypt and Mesopotamia in around 3500 to 3000 BCE.

After the fall of the Western Roman Empire, information on Greek originations of the world crumbled in Western Europe during the early hundreds of years (400 to 1000 CE) of the Middle Ages however was protected in the Muslim world during the Islamic Golden Age.

The recuperation and osmosis of Greek works and Islamic investigations into Western Europe from the tenth to thirteenth century restored “normal philosophy“, which was later changed by the Scientific Revolution that started in the sixteenth century as new thoughts and disclosures withdrew from past Greek originations and traditions.

It was not until the nineteenth century that a large number of the institutional and expert highlights of science started to take shape; alongside the evolving of “common way of thinking” to “regular science.”

Present Day and Science

Present-day science is commonly partitioned into three significant branches that comprise of the normal sciences (e.g., science and material science), which study nature in the broadest sense;

The sociologies (e.g., financial matters, brain research, and human science), which study people and social orders; and the conventional sciences (e.g., rationale, arithmetic, and hypothetical software engineering), which study dynamic ideas.

There is disagreement, in any case, on whether the conventional sciences really establish science as they don’t depend on exact evidence. Disciplines that utilization existing logical information for useful purposes, for example, designing and medication, are depicted as applied sciences.

Science depends on to explore, which is generally led in scholastic and research foundations just as in government organizations and private organizations.

However, the handy effect of logical research has prompted the rise of science arrangements that try to impact the logical undertaking by organizing the improvement of business items, weapons, medicinal services, and natural assurance.

Components of Science

We are now living in a very comfortable environment due to advancements in Science and Technology. Let us now talk about different aspects of Modern Science, during the 19th century, the practice of science became professionalized and institutionalized.

There are basically two diversification of Modern Science Natural Sciences and Social Sciences.

Natural Science

This is the branch of Science in which, the study of the natural world is done using scientific psychology. Natural Science is categorized on the basis of which aspect of the natural world we are studying like the study of life is comes under biology.

Let us see these parts in brief,


Physics is the study of nature and how it works. In Physics we study mostly nonliving stuff. Like light, electricity, motion, heat, and many more things.

In 1687, Isaac Newton published the Principia Mathematica, detailing two comprehensive and successful physical theories: Newton laws of motion, which pretty much explained motion in which happened visible motion around us.

Newton invented Calculus, and Discovered Gravity, Dispersion of light. His contribution to it is extraordinary. Guys like Faraday, J.C.Maxwell, Pascal, Joul, and many more boosted field of physics.

In the 20th century, limelight was on Albert Einstein Theory of Relativity, and this time modern physics was a new name for physics.


Chemistry is the scientific method in which interaction of mater is studied. In Chemistry, there are people just mix stuff and see what is the result of it, in Ancient days there was no difference between Alchemy and chemistry.

In 1661, “chemistry” was distinguished from alchemy by Robert Boyle.

Other important steps included the gravimetric experimental practice of medicinal chemists like William Cullen, Joseph Black, Torbern Bergman, and Pierre Macquer.

Through the work of Antoine Lavoisier ( “Father of Modern Chemistry”)  on oxygen and the law of conservation of mass, which led to the phlogiston theory.

Then in 1803, by John Dalton’s theory of all matter, which was an attempt to explain matter is made up of tiny particles known as atoms. Then in the 19th century, a new infield in chemistry emerged known as Organic Chemistry,  where we can synthesis lots of Organic Compounds.


It existed for a very long time but it doesn’t come under science for a long time. Geology is the study of basically earth rocks, minerals, landforms, weather, cloud, and earth structure

Geology did not undergo systematic restructuring during the Scientific Revolution, but individual theorists made important contributions.

Astronomy Science

Astronomy is the study in which people study the stars, planets position, and about the Universe. So, advances in astronomy and in optical systems in the 19th century resulted in the first observation of an asteroid in 1801.

And the discovery of Neptune in 1846. However, now the discovery of Black Hole, Gravitational waves, Nova, Blue Star, Earth-like planets, and much more discovery happened recently.

Biology and Medicine

Biology is the study of life. The early explorers of biology think it as an exploration of the soul. Through the study of Biology people started to live in more sublet and clean environments.

So, in 1847 Hungarian physician Ignac Fulop Semmelweis dramatically reduced the occurrence of puerperal fever by simply requiring physicians to

wash their hands before attending to women in childbirth. Charles Darwin was an amazing biologist. His theory of evolution by natural selection.


In Ecology people study the cycle of life. Yeah, it is also related to living beings. However, Microbiology and Social Science both played an important part in the rise of ecology.

In the 1930s, Arthur Tansley and others began developing the field of ecosystem ecology, which combined experimental soil with physiological concepts of energy and the techniques of field biology.  

Social Sciences

Social Sci is the scientific study of humans in society and in community. With employment of scientific methods it has developed so much, human behavior, psychology, civics, how humans act in certain situation these kind of things are studied. Lets take a look into parts of social sciences.


The development of science is remarkable throughout the years. Science exploration started 1000s of years ago and we still exploring it. Medicine, Electronics, Social Relief, Comfort, and many other things are creation of science.

With it, we are able to land on the moon and start living this comfy life. So it plays a very important role in our life.

We took a brief look at what is science and its different parts. Hope you guys liked it.


Q1) Difference between Ecology and Biology?

Ans: Biology is the study of the anatomy, physiology, ecology, cellular and molecular biology of all living things. Ecology focuses on the environment, climate, and natural resources and how animals and plants respond to those factors.

Q2) Which Sciences is related to study of life?

Ans: Biology is related to study of life.

Q3) What are the components of Science?

Ans: Above all Physics, Chemistry, Biology, Geology, Astronomy, Ecology, Social Sciences are components of it.
