A Complete Guide to learn Science, Biology, Physics and chemistry with simple explanation. This app provides the best study material for all the beginners and expert level students who want to learn science. Learn Science Science is the pursuit and application of knowledge and understanding of the natural and social world following a systematic methodology based on evidence. Scientific methodology includes the following: Evidence. Experiment and/or observation as benchmarks for testing hypotheses. Learn Biology Biology is the study of life. The word "biology" is derived from the Greek words "bios" (meaning life) and "logos" (meaning "study"). In general, biologists study the structure, function, growth, origin, evolution and distribution of living organisms. Learn Biology is a natural science discipline that studies living things. It is a very large and broad field due to the wide variety of life found on Earth, so individual biologists normally focus on specific fields. These fields are either categorized by the scale of life or by the types of organisms studied. Learn Physics Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, and its main goal is to understand how the universe behaves. The science of the behavior of the physical world. Stemming from the Greek "physis," which means the characteristics of nature, physics covers the structure of matter (atoms, particles, etc.) and a huge variety of subjects, including chemical bonding, gravity, space, time, electromagnetism, electromagnetic radiation, the theory of relativity, thermodynamics and quantum mechanics. Learn Chemistry The branch of natural science that deals with the composition and constitution of substances and the changes that they undergo as a consequence of alterations in the constitution of their molecules is called chemistry. Chemistry is one branch of science. Science is the process by which we learn about the natural universe by observing, testing, and then generating models that explain our observations. Because the physical universe is so vast, there are many different branches of science. Thus, chemistry is the study of matter, biology is the study of living things, and geology is the study of rocks and the earth. Mathematics is the language of science, and we will use it to communicate some of the ideas of chemistry. Learn Science is the field, that is, it develops a body of knowledge by observing things and performing experiments. The meticulous process of gathering and analyzing data is called the "scientific method,".
