SSC Science Note. The purpose of science education is the development of observational capability and the formation of the positive attitude of the learners to the elements of the environment through the creation of curiosity on various natural phenomena. Basically keep an eye on these factors, the book entitled Science has been written in light of the revised curriculum. To make the book more interesting to the learners, different types of hands-on tasks have been included along with the theoretical aspects of science.
SSC Science Note
Considering the challenges and commitments of the 21st Century and following the revised curriculum, this textbook has been written as a trial edition. Therefore, we welcome with our highest consideration any constructive and logical suggestions for further improvement of the book. Amidst huge activities needed for introducing textbooks, this one has also been written within a very short span of time. Therefore, some errors may remain in this book. We will continue our efforts to make the next edition free from errors, more beautiful and decent.

Modern science is typically divided into three major branches that consist of the natural sciences (e.g., biology, chemistry, and physics), which study nature in the broadest sense; the social sciences (e.g., economics, psychology, and sociology), which study individuals and societies; and the formal sciences (e.g., logic, mathematics, and theoretical computer science), which study abstract concepts. There is disagreement, however, on whether the formal sciences actually constitute a science as they do not rely on empirical evidence. Disciplines that use existing scientific knowledge for practical purposes, such as engineering and medicine, are described as applied sciences.
Science is based on research, which is commonly conducted in academic and research institutions as well as in government agencies and companies. The practical impact of scientific research has led to the emergence of science policies that seek to influence the scientific enterprise by prioritizing the development of commercial products, armaments, health care, and environmental protection.
The early Greek philosophers of the Milesian school, which was founded by Thales of Miletus and later continued by his successors Anaximander and Anaximenes, were the first to attempt to explain natural phenomena without relying on the supernatural. The Pythagoreans developed a complex number of philosophy:467–68 and contributed significantly to the development of mathematical science. :465 The theory of atoms was developed by the Greek philosopher Leucippus and his student Democritus. The Greek doctor Hippocrates established the tradition of systematic medical science and is known as “The Father of Medicine”.
This was a reaction to the Sophist’s emphasis on rhetoric. The Socratic method searches for general commonly held truths that shape beliefs and scrutinizes them to determine their consistency with other beliefs. Socrates criticized the older type of study of physics as too purely speculative and lacking in self-criticism. Socrates was later, in the words of his Apology, accused of corrupting the youth of Athens because he did “not believe in the gods the state believes in, but in other new spiritual beings”. Socrates refunds these claims, but was sentenced to death.: 30e
