introduction to quantum mechanics experiments

Animals are different from plants because of their ability of locomotion. This ability probably developed as they have to search for food, unlike the plants that are autotrophic. Since they move from place to place, the animals have to continuously encounter changes in their environment. All animal..

Suppose the two events are not independent, that is the occurrence of one depends on the occurrence of other, then how do we compute This can be explained by conditional probability. Baye's theorem is named after the British mathematician Thomas Bayes who published it in a research pa..

Humans have always been curious about the world around them. The world has an astonishing variety of materials and bewildering diversity of life and behaviour. The inquiring and imaginative human mind has responded to the wonder and awe of nature in different ways. This human endeavour led, in cour..

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 characterize them, it is imp..

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. This is possible only if th..

Transportation whether in plants or animals is the key to the efficient assimilation of the nutrients that the organisms synthesise, get from their environment or digest. The study of these processes helps us in many ways. The study of transport mechanisms in plants helps us to understan..

Rasipuram Krishnaswamy Narayan was born on 10 th October 1906 in Madras in India. He was a prolific Indian writer whose exquisitely crafted stories and novels provided witty and perceptive observations about life in India. He has published numerous novels, five collections of short stories, tw..

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 proteins, carbohydrates and..

The word force in common usage refers to a push or pull. The word Mass is also just as familiar as the word force. A super tanker is one that contains an enormous amount of mass. In comparison a coin does not contain much mass. During the seventeenth century Newton developed three important laws th..

In the previous chapter we have seen how light gets reflected when it is incident on a surface. Now let us see what happens when a ray of light traveling from one medium to another medium of different density. It is a matter of common experience that a swimming pool appears to have less d..
