L. A. Ramdas
Lakshminarayanapuram Ananthakrishnan Ramdas (3 June 1900 – 1 January 1979) was an Indian physicist and meteorologist, known for discovering the atmospheric phenomenon of the Ramdas layer or Lifted Temperature Minimum where the lowest temperature in the atmosphere is not on the ground but a few tens of centimeters above the ground resulting. This can be seen in thin layer fogs which are at some height above the ground. He has been called the father of agricultural meteorology in India. Life Ramdas was born in Palghat, Kerala and after his graduation he trained in physics and was a student of C. V. Raman as Palit Research Scholar from 1923-1926. He worked on light scattering and recorded what is now called the "Raman effect". He received a Ph.D. from the Calcutta University and joined the Indian Meteorological Department on September 15, 1926 at Simla. He also briefly studied thin-films and in 1927 he boldly suggested that the observed decline in rainfall over half a century ...

Agra
Agra (, ) is a city on the banks of the Yamuna river in the Indian state of Uttar Pradesh, about south-east of the national capital New Delhi and 330 km west of the state capital Lucknow. With a population of roughly 1.6 million, Agra is the fourth-most populous city in Uttar Pradesh and List of cities in India by population, twenty-third most populous city in India. Agra's notable historical period began during Sikandar Lodi's reign, but the golden age of the city began with the Mughals. Agra was the foremost city of the Indian subcontinent and the capital of the Mughal Empire under Mughal emperors Babur, Humayun, Akbar, Jahangir and Shah Jahan. Under Mughal rule, Agra became a centre for learning, arts, commerce, and religion, and saw the construction of the Agra Fort, Sikandra, Agra, Sikandra and Agra's most prized monument, the Taj Mahal, built by Shah Jahan as a mausoleum for his favourite empress. With the decline of the Mughal empire in the late 18th century, the ci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Convection
Convection is single or multiphase fluid flow that occurs spontaneously due to the combined effects of material property heterogeneity and body forces on a fluid, most commonly density and gravity (see buoyancy). When the cause of the convection is unspecified, convection due to the effects of thermal expansion and buoyancy can be assumed. Convection may also take place in soft solids or mixtures where particles can flow. Convective flow may be transient (such as when a multiphase mixture of oil and water separates) or steady state (see Convection cell). The convection may be due to gravitational, electromagnetic or fictitious body forces. Heat transfer by natural convection plays a role in the structure of Earth's atmosphere, its oceans, and its mantle. Discrete convective cells in the atmosphere can be identified by clouds, with stronger convection resulting in thunderstorms. Natural convection also plays a role in stellar physics. Convection is often categorised or d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermal Radiation
Thermal radiation is electromagnetic radiation generated by the thermal motion of particles in matter. Thermal radiation is generated when heat from the movement of charges in the material (electrons and protons in common forms of matter) is converted to electromagnetic radiation. All matter with a temperature greater than absolute zero emits thermal radiation. At room temperature, most of the emission is in the infrared (IR) spectrum. Particle motion results in charge-acceleration or dipole oscillation which produces electromagnetic radiation. Infrared radiation emitted by animals (detectable with an infrared camera) and cosmic microwave background radiation are examples of thermal radiation. If a radiation object meets the physical characteristics of a black body in thermodynamic equilibrium, the radiation is called blackbody radiation. Planck's law describes the spectrum of blackbody radiation, which depends solely on the object's temperature. Wien's displacement law de ...

Bhadrachalam
Bhadrachalam is a census town in Bhadradri Kothagudem district in the Indian state of Telangana. It is an important Hindu pilgrimage town with the Bhadrachalam Temple of Lord Rama, situated on the banks of Godavari river. It is located east of state capital, Hyderabad, from Khammam, from Warangal, from the Andhra Pradesh state capital Amaravathi and from Visakhapatnam. History The town has a documented history of Lord Sri Rama temple constructed circa 17th century CE by Kancherla Gopanna. Gopanna (1620 - 1680), popularly known as Bhadradri Ramadasu or Bhadrachala Ramadasu, was a 17th-century Indian devotee of Rama and a composer of Carnatic music. His devotional lyrics to Rama are famous in South Indian classical music as Ramadaasu Keertanalu, and have made Bhadrachalam a place of religious importance for Hindus. Bhadrachalam area also has several Hindu temples connected with epic Ramayana. It is referred as "Dakshina Saketa Puri" in the movie "Sri Ramadasu". Geogr ...

Physicist
A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms. Physicists work across a wide range of research fields, spanning all length scales: from sub-atomic and particle physics, through biological physics, to cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their knowledge towards solving practical problems or to developing new technologies (also known as applie ...
