Fields of Science

Science is derived from Latin word called "scienta" which literally means "knowledge". Science is the study of nature. It is a natural philosophy which describes how things work in nature. Science is a way of understanding the world.

It is because of the scientific laws and equations that helped us to predict the motion of objects which helped us to invent machinery. Science helps us to determine how the nature can be used to enhance our living. Science extends and enriches our lives, expands our imagination and liberates us from the bonds of ignorance, doctrine and superstition. It is because of the development in science and technology that our life is changing everyday. As an example, we can compare our present life with the life just a decade ago. TO see more contrast, we can compare our life with the people from previous centuries. Therefore, it is important for all to realize some important basic scientific laws which we use in our daily life. Being scientifically illiterate, someone misses the advantage of making their life easier to perform everyday activities. Here are some important scientific theories that everybody should at least know to enrich the knowledge and realize how life has started and how nature works.

Here are many of the terms used to describe various fields of scientific study.
