Science > Physics > Units and Measurements > Measurement of Time In this article, we shall study techniques of measurement of time. Time is the interval between two events. The study and science of time measurement is called chronometry or horology. Chronology, as opposed to chronometry, is the science of arranging events in their order or sequence […]
Science > Physics > Units and Measurements > Measurement of Density In this article, we shall study the measurement of the density of a substance. Eureka! Eureka! Archimedes was a Greek scientist. He lives in Syracuse nearly 200 years ago. The King of the land wanted to wear a Golden Crown. He gave some gold […]
Science > Physics > Units and Measurements > Measurement of Mass and Weight In previous articles, we have studied measurements of length, area, and volume by different methods. In this article, we shall study the measurement of mass and weight of a body. Measurement of Mass of a Body: Mass is a measure of matter […]
Science > Physics > Units and Measurement > Measurement of Length, Area, and Volume > Measurement of Area and Volume In this article, we shall study methods of the measurement of area and volume. Measurement of Area: Measurement of Area of Irregular Shape: The area of an irregular object can be obtained by drawing an […]
Science > Physics > Units and Measurement > Measurement of Length, Area, and Volume > Measurement of Terrestrial Distances, Heights and Depths In the last article, we have studied measurement of distances between heavenly bodies. In this article, we shall study methods of the mesurements of terrestrial distances. An instrument used for Measurement of Bearings: […]
Science > Physics > Units and Measurement > Measurement of Length, Area, and Volume > Distances of Heavenly Bodies from the Earth In this article, we shall study the parallax and other methods to find the distance between two heavenly bodies. Parallax: Hold a pencil vertically in front of you at a certain distance against […]
Science > Physics > Units and Measurement > Measurement of Length, Area, and Volume > Use of Micrometer Screw Gauge Physics is a science of measurement. In science and engineering, we perform experiments. During experiments, we have to take readings. Thus all these experiments require some measurements to be made. During the production of mechanical […]

During experiments, we have to take readings. Thus all these experiments require some measurements to be made. During the production of mechanical products, […]
Science > Physics > Semiconductors > Introduction Semiconductors are the substances whose conductivity lies between the conductors and insulators e.g. Germanium, Silicon, etc. These elements are members of the fourth group of the periodic table with valency 4. These elements have a partially filled conduction band and partially filled valence band. There are no free […]
