is the observation, identification, description, experimental investigation, and theoretical explanation of phenomena.
There are different types of science. Exact sciences and Descriptive sciences. Exact sciences are those which typically require precise measurements like Physics and Chemistry. Descriptive sciences are those which are more often oriented towards classification and description, such as biology and paleontology.
Natural sciences are typically divided into the physical sciences and the biological sciences, both of which can be subdivided. The major physical sciences are physics, astronomy, chemistry, and geology; the main biological sciences are botany and zoology.
The Branches of Science may include:
Physical Sciences: any of the natural sciences dealing with inanimate matter or with energy, as physics, chemistry, and astronomy.
Physics is the science of matter and energy, including light, sound, electricity, magnetism, radiation, and motion.

Mathematics while not a science, Mathematics is closely allied to the sciences because of the extensive use of math in science. It is frequently referred to as the language of science, and is the most important and objective means for communicating the results of science.
