Microscope

A microscope is a device for viewing objects that are too small to be seen by the naked or unaided eye. The science of investigating small objects using such an instrument is called microscopy. The word microscopic means minute or very small, not visible with the eye unless aided by a microscope. The microscopes used in schools and homes sketch their history back almost 400 years.

Fruit

All citrus trees are of the single genus Citrus, and remain largely interbreed able; that is, there is only one "super species" which includes lemons, limes and oranges. Nevertheless, names have been given to the various members of the citrus family, oranges often being referred to as Citrus sinensis and Citrus aurantium. Fruits of all members of the genus Citrus are considered berries because they have many seeds, are fleshy and soft, and derive from a single ovary. An orange seed is called a pip.

Natya Shastra of Bharata

The Natya Shastra of Bharata is the main work of dramatic theory in the Sanskrit drama of classical India. It was written by the sage Bharata Muni. It is a set of precept on the writing and performance of dance, music and theatre. While the Natyasastra primarily deals with stagecraft, it has come to influence music, dance, and literature as well. Thus, an argument can be made that the Natyasastra is the foundation of the fine arts in India.

Traffic

Traffic is the movement of motorized vehicles, notarized vehicles and pedestrians on roads. Traffic laws are the laws which govern traffic and regulate vehicles, while rules of the road are both the laws and the informal rules that may have developed over time to facilitate the orderly and timely flow of traffic. Organized traffic normally has well-established priorities, lanes, right-of-way, and traffic control at intersections.
