 This universe moves in the specific path with time. Each and every activities and phenomena happening in universe has explanations. These explanations with specific theoretical background are Science. Science involve in each and every sectors, so depending upon its specific area of explanation it is classified in four groups: Natural Science, social science, formal science and applied science. All the groups have its own field of expertise. While dealing with natural science, the word nature in itself becomes very huge. To simplify natural science, it is sub classified in two groups: one is physical science and another is life science. Science which deals with the nonliving systems is Physical science still some sectors of physical science deals with biological phenomena. Physical science in itself is a vague topic. It is divided into physics, chemistry and Earth science. Each division also contains many subdivisions. In short physical science deals with all the matters around us and the study of energy in the universe. Here not only the introduction but its formation, properties, transformations, applications are also described in detail.


Physics is the branch of physical science where matters are studied for their transformation, energy conservation and application on the basis of their properties. In static physics energy of matters are studied in rest mode where as in kinematics energy at mobile state are explained. Static and kinematics both lie under the class dynamics. Acoustic science deals about the sound energy, its transformation and applications. The very minute particles like atom have also significant energy which is well explained by nuclear physics. The recent focus of the universe is in atomic energy. The technologies in the sectors of electronics, communications, automobiles, space crafts, Industrial and thermodynamics are outcome of physics which had made the human life easier.

Chemistry is the central science where the matters, their preparations, properties, transformations and applications are studied on the basis of their reactivity, chemical bonds, and electronic interactions in atomic level. Chemistry is in practice from very long ago with the heading alchemy. This science correlates natural life science with physic and earth science. Chemistry is sub-divided as physical chemistry, inorganic chemistry and organic chemistry. Physical chemistry gives detail explanation about material’s transformation, reaction ratio, kinetics, and thermodynamics. Different possible combinations of elements in periodic tables were prepared under inorganic chemistry to form compounds with different properties for different applications to meet the necessity of the advancement of new era. Organic chemistry is also huge science but concerned with very few elements; carbon, hydrogen and few more foreign elements nitrogen, sulphur, phosphorous and halogens. The catenation property of carbon made this branch of chemistry unsaturated forever so that the thirst of knowledge always keeps the upgrading organic chemistry. It is also called as carbon chemistry. Here not only the trivial study is done but also the synthetic translation for the natural rare materials like muscon and civetene are prepared.

Earth science is the natural science where natural resources their occurrence, life style and system in that environment is studied. It is subdivided in ecology, oceanology, geology, meteorology. Ecology is the life cycle study in that particular environment. Nature has its own balancing system for the organism as well as for natural resources. Likewise in oceanology, the life under water is studied to develop the technologies in water so we can call it marine science as well. Geology is the science of earth surface where not only the life but also the morphological study of earth crust and its constituents were studied. Here internal movements of the magma and other earthy particles inside and outside the earth crust were kept in account to forecast the natural disasters like volcanoes, landslides etc. Besides this, different types of ores, mines, minerals, their extraction and applications are also a part of geology. Our nature is not only earth and water but also the neighbour surrounding like air, pressure, different polymorphs of water like dew, moisture, ice, snow, fog, steam, cloud etc. which enclose our earth. The study of atmosphere or surrounding is meteorology. These surroundings also interact with the all living and nonliving sciences. Depending upon the interaction of atmosphere with the types of sciences meteorology also differs like hydrometeorology, climatology, atmospheric physics, atmospheric chemistry etc. This science most correctly forecast the future natural disaster like tsunami, global warming, climate change, and tornado, floods which help us to do some preventive majors and take some precaution as well.

Physical science is an intimate part of our life which facilitates us with numerous sophisticated technologies with advancement in our daily routine like aircrafts, microwaves, laptop mobiles, good medications, higher technology bearing software, good architectures, advance materials with significant magnetic and optical properties, good transportation not only that but also in a small place one can get the information and have a look around the whole universe. Physical science is the main booster of this upgrading universe.
