introduction to quantum mechanics experiments

Introduction - Biomolecules are complex organic molecules. These molecules form the basic structural constituent of a living cell. The organic compounds such as amino acids, nucleotides and monosaccharides serve as building blocks of complex biomolecules. The important biomolecules are pr..

Mechanics, the oldest physical science, is the study of motion of objects. It is applied in calculation of the path of an artillery shell, a space probe sent from earth to Mars, et..

Introduction - Processes by which substances are transformed to one or several products are called chemical reactions. Chemical processes that occur in the presence of light, like sunlight, are called photochemical reactions. These processes can occur naturally or under controlled conditi..

Introduction - Genes do not operate to produce enzymes all the time. Each gene is normally more or less repressed (inactive); but, when a particular enzyme is needed, the relevant gene becomes active to bring about the production of that enzyme. A totally active gene can produce a very la..

Energy - Energy is a number that we associate with a system of one or more objects. If a force acts on one of the objects, making it move, then the number changes. After countless experiments, scientists and engineers realised that if the scheme by which we assign these energy numbers is ..

Introduction - The goal of physics is to provide an understanding of nature. The science of physics was developed to explain our physical environment. Great Physicists like Galileo, Newton, and Einstein etc. framed laws to explain the various phenomena in nature. These laws have been veri..

Introduction - All living creatures need food. The food is consumed so that energy is obtained. The energy is utilised by the body for various purposes like locomotion, conduction of impulses, repair of damaged tissues, building of cell materials, etc. The substance that is used to releas..

Introduction - Organic compounds are isolated either from natural sources or from reaction mixtures. These compounds are seldom pure and are usually contaminated with small amounts of other similar compounds, which are found to exist together or formed during the reaction. In order to cha..

Introduction - As the complexity of the individuals, plants or animals increases the different cells and organs become separated from each other by greater distance. Thus it becomes necessary to have a system by which the different parts of the organisms can function as a single unit. Thi..

Introduction - Born in San Francisco, Frost spent most of his adult life in rural New England and his laconic language and emphasis on individualism in his poetry reflect this region. He attended Dartmouth and Harvard but never earned a degree, and as a young man with a growing family he ..
