What is Science ?

So what is science? In fact the term science itself comes from a Latin word that means Knowledge and the names of many branches of sciences. Science is the study of the physical and natural world by observations and experimentations that mean in science two things are very important.

  1. observations
  2. experimentations

It is a systematic way of observing the world first and then doing some experiments to understand its structure and behavior. It is a logical way of knowing about the universe and then giving an explanation of how it works.

Scientific Method

Scientific Method the knowledge of science is in fact based upon a method known as scientific method. In scientific method.

  • We first ask a question about a problem
  • Then do a research about it
  • Make a hypothesis, do an experiment
  • Collect data
  • Make another observation
  • Finally come to a conclusion

These are basically different steps through which we come to know the actual reason behind a phenomenon.

Importance of science

science leads to new knowledge and new discoveries. It has expands our understanding of the life on Earth. Basically on different planets as well. We are finding the existence of life on Mars. It facilitates the progress and development it also helps to defies false beliefs. It has enabled us to think critically and logically. it has solved a lot of our problems.

Branches of science

Modern science can be divided into three main branches. One of them is the natural sciences. Natural Sciences are further divided into physics, chemistry and biology. Physics is a study of the universe whereas chemistry is a study of the matter and biology is a study of a life and living organisms. Likewise social sciences include psychology, sociology, history, law, etc. And then formal sciences includes mathematics statistics, data science, computer science.

Our lives are affected deeply by science. In fact, it pervades almost all aspects of our modern life. Below are some areas where science affects our daily lives:


Medicine has been enhanced by the development of new technology, treatments and drugs – thanks to the impact of science on healthcare. Applying science in medicine has improved treatment and increased longevity. Medical research also improves surgical techniques helps diagnose and treat diseases more effectively and develops vaccines thus saving millions of lives.


Invention of telephone and radio to development of internet and smartphones have changed communication due to scientific breakthroughs. This means that individuals can communicate immediately over long distances as a result fostering collaboration, sharing of information and connecting with others from every corner in the world.


Science contributes greatly towards transportation systems hence leading to safer modes of travel which are also eco-friendly thereby resulting into efficient modes of transport. For example, improvements in automotive engineering, air travel, public transportation have made it easier and quicker for people to commute or travel around as well as move goods contributing significantly towards economic growth and global connectivity.


Science plays an important role in the development of renewable energy sources, including solar, wind, hydroelectricity and energy storage and efficiency. Such technologies can help reduce the dependence on fossil fuels, address climate change and promote sustainable development.

Food and Agriculture

Through research, farming has been improved by increasing crop yields as well as safety and security in food production. Global food challenges are addressed at a point where biotechnology, genetic engineering or/and precision agriculture techniques produce resilient as well as nutritious crops that support sustainable agriculture.


Science helps us to understand environmental issues like climate change, pollution or biodiversity loss thereby providing a basis for conservation efforts and environmental management. Solutions are developed through monitoring systems modeling analysis to minimise the environmental impact which promotes sustainability.

Entertainment and Leisure

From the creation of video games to advances in film making scientific knowledge is effectively used in entertainment activities. Cultural experiences, artistic expression and recreations also benefit from scientific findings which contribute to our life enrichment with widening horizons.


The second prompt is about education. Science Education encourages the development of critical thinking and problem-solving skills, and scientific literacy, enabling individuals to make informed decisions and engage with complex societal issues. STEM (science, technology, engineering and mathematics) education trains students for science-related jobs and drives innovation as well as economic growth.

Generally speaking, science pervades our lives profoundly leading to progress, innovation and social betterment. This can improve human welfare by embracing scientific investigation honing its capabilities to solve problems; this will be a better future for humanity.

Types of Science

Science can generally be divided into a variety of branches or disciplines, each concentrating on different aspects of nature and using separate methodologies. The following are some major types of sciences:

1.Natural Sciences

These study the physical world and natural phenomena such as matter, energy, space and time. Major Types of natural science include:


The study of matter, energy and basic forces that exist in nature.


The study of composition, behavior and interaction between different substances.


The science that deals with living things and their interactions with each other and the environment.

Earth Sciences (Geosciences)

This branch includes subjects like geology, meteorology, oceanography, environmental science.

2.Formal Sciences

These are concerned with abstract ideas or theoretical systems which typically use mathematical or logical techniques to examine patterns and structures. Main Kinds of formal science include:


A field which deals with numbers, quantities shapes patterns including their relationships.

Computer Science

It is a discipline that studies algorithms data structures computation information processing.

3.Social Sciences

The social sciences involve the study of human behavior, societies and institutions through empirical observation and analysis in order to analyze social phenomena and processes. These include:


Analyzing the mind, actions and mental processes.


Examining human communities, social interactions as well as their arrangements.


It is about the production, distribution and consumption of goods and services; it studies the conducts of individuals as well as entities within economic systems.

Political Science

This major looks after political institutions, systems, behavior and power politics.

4.Applied Sciences

Applied sciences use scientific knowledge and principles to solve practical problems or invent new technologies for particular purposes. Examples of applied sciences are:


This discipline involves designing, constructing and maintaining structures, machines or systems using scientific or mathematical principles.


The science used to diagnose diseases, treat them cure some while control others is referred to as medicine

Agricultural Science

It deals with crop production animal husbandry soil management etc

These categories are not mutually exclusive and often there is overlap in different branches of science. Besides interdisciplinary fields such as bioinformatics, environmental science and materials science are merging concepts and methodologies from different scientific disciplines as a way of solving hard problems.
