Main Branches of Science

Most Important Branches in Science.

                        Zoology is the study of animals. Ornithology, the study of birds. Ichthyology, the study of fishes. Mycology, the study of fungi.

                        Microbiology, the study of micro-organisms. Protozo-ology, the study of one-celled animals. Herpetology, the study of amphibians and reptiles. Entomology, the study of insects.

3. Chemistry

Chemistry is the science that deals with the properties, composition,

and structure of substances known as elements and compounds, the transformations that they undergo, and the energy that is released or absorbed during these processes.

                        Every substance, whether naturally occurring or artificially produced, consists of one or more of the hundred-odd species of atoms that have been identified as elements.

                        Although these atoms, in turn, are composed of more elementary particles, they are the basic building blocks of chemical substances; there is no quantity of oxygen, mercury, or gold, for example, smaller than an atom of that substance.

                        Chemistry, therefore, is concerned not with the subatomic domain but with the properties of atoms and the laws governing their combinations and with how the knowledge of these properties can be used to achieve specific purposes.

                        Chemistry also is concerned with the utilization of natural substances and the creation of artificial ones. Cooking, fermentation, glass making, and metallurgy are all chemical processes that date from the beginning of civilization.

4. Physics

Physics is the science that deals with the structure of matter and the

interactions between the fundamental constituents of the observable universe.
