What are the branches of science and their definition?

Answer 1

• Biology -study of living things
• physics -study of forces of nature
• chemistry -study of matter, elements, chemical substances & their composition

These are not all but most:

Aerodynamics: the study of the motion of gas on objects and the forces createdAnatomy: the study of the structure and organization of living thingsAnthropology: the study of human cultures both past and presentArchaeology: the study of the material remains of culturesAstronomy: the study of celestial objects in the universeAstrophysics: the study of the physics of the universeBacteriology: the study of bacteria in relation to diseaseBiochemistry: the study of the organic chemistry of compounds and processes occurring in organismsBiophysics: the application of theories and methods of the physical sciences to questions of biologyBiology: the science that studies living organismsBotany: the scientific study of plant lifeChemical Engineering: the application of science, mathematics, and economics to the process of converting raw materials or chemicals into more useful or valuable formsChemistry: the science of matter and its interactions with energy and itself

Climatology: the study of climates and investigations of its phenomena and causesComputer Science: the systematic study of computing systems and computationEcology: the study of how organisms interact with each other and their environmentElectronics: science and technology of electronic phenomenaEngineering: the practical application of science to commerce or industryEntomology: the study of insectsEnvironmental Science: the science of the interactions between the physical, chemical, and biological components of the environmentForestry: the science of studying and managing forests and plantations, and related Natural ResourcesGenetics: the science of genes, heredity, and the variation of organismsGeology: the science of the Earth, its structure, and historyMarine Biology: the study of animal and plant life within saltwater ecosystemsMathematics: a science dealing with the logic of quantity and shape and arrangementMedicine: the science concerned with maintaining health and restoring it by treating diseaseMeteorology:study of the atmosphere that focuses on weather processes and forecastingMicrobiology: the study of microorganisms, including viruses, prokaryotes and simple eukaryotesMineralogy: the study of the chemistry, crystal structure, and physical (including optical) properties of mineralsMolecular Biology: the study of biology at a molecular levelNuclear Physics: the branch of physics concerned with the nucleus of the atomNeurology: the branch of medicine dealing with the nervous system and its disordersOceanography: study of the earth's oceans and their interlinked ecosystems and chemical and physical processesOrganic Chemistry: the branch of chemistry dedicated to the study of the structures, synthesis, and reactions of carbon-containing compoundsOrnithology: the study of birdsPaleontology: the study of life-forms existing in former geological time periodsPetrology: the geological and chemical study of rocksPhysics: the study of the behavior and properties of matterPhysiology: the study of the mechanical, physical, and biochemical functions of living organismsRadiology: the branch of medicine dealing with the applications of radiant energy, including x-rays and radioisotopesSeismology: the study of earthquakes and the movement of waves through the EarthTaxonomy: the science of classification of animals and plantsThermodynamics: the physics of energy, heat, work, entropy and the spontaneity of processesZoology: the study of animals
