Waman Dattatreya Patwardhan
Waman Dattatreya Patwardhan (30 January 1917 – 27 July 2007) was an IOFS officer, nuclear chemist, defence scientist and an expert in the science of Explosives engineering. He was the founder director of the Explosives Research and Development Laboratory (now known as the High Energy Materials Research Laboratory (HEMRL)) of India. He is considered one of the distinguished scientists in India due to his contributions to Indian space program, Indian nuclear program and missile program in their early stages. He developed the solid propellant for India's first space rocket launched at Thumba. He was responsible for developing the detonation system of India's first nuclear device which was successfully tested in 1974, an operation codenamed Smiling Buddha. Other areas of work: Wrote a book on Hydroponics and developed a cost-effective method for producing parabolic mirrors for astronomical telescopes.

Indian Space Program
The Department of Space is an Indian government department responsible for administration of the Indian space program. It manages several agencies and institutes related to space exploration and space technologies. The Indian space program under the DoS aims to promote the development and application of space science and technology for the socio-economic benefit of the country. It includes two major satellite systems, INSAT for communication, television broadcasting and meteorological services, and Indian Remote Sensing Satellites (IRS) system for resources monitoring and management. It has also developed two satellite launch vehicles Polar Satellite Launch Vehicle (PSLV) and Geosynchronous Satellite Launch Vehicle (GSLV) to place IRS and INSAT class satellites in orbit. History In 1961, the Government of India and then Prime Minister Jawaharlal Nehru entrusted the responsibility for space research and for the peaceful use of outer space to the Department of Atomic Energy (DA ...

Scientists From Madhya Pradesh
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.'''' History The ...

Government Of India
The Government of India (ISO: ; often abbreviated as GoI), known as the Union Government or Central Government but often simply as the Centre, is the national government of the Republic of India, a federal democracy located in South Asia, consisting of 28 union states and eight union territories. Under the Constitution, there are three primary branches of government: the legislative, the executive and the judiciary, whose powers are vested in a bicameral Parliament, President, aided by the Council of Ministers, and the Supreme Court respectively. Through judicial evolution, the Parliament has lost its sovereignty as its amendments to the Constitution are subject to judicial intervention. Judicial appointments in India are unique in that the executive or legislature have negligible say. Etymology and history The Government of India Act 1833, passed by the British parliament, is the first such act of law with the epithet "Government of India". Basic structure Th ...

Hydroponics
Hydroponics is a type of horticulture and a subset of hydroculture which involves growing plants, usually crops or medicinal plants, without soil, by using water-based mineral nutrient solutions in aqueous solvents. Terrestrial or aquatic plants may grow with their roots exposed to the nutritious liquid or in addition, the roots may be mechanically supported by an inert medium such as perlite, gravel, or other substrates. Despite inert media, roots can cause changes of the rhizosphere pH and root exudates can affect rhizosphere biology and physiological balance of the nutrient solution by secondary metabolites. Transgenic plants grown hydroponically allow the release of pharmaceutical proteins as part of the root exudate into the hydroponic medium. The nutrients used in hydroponic systems can come from many different organic or inorganic sources, including fish excrement, duck manure, purchased chemical fertilizers, or artificial nutrient solutions. Plants are com ...

Thumba
Thumba is a coastal area of Thiruvananthapuram city, the capital of Kerala, India. Location and geography Thumba is a vast village bordering Menamkulam in the east, St. Dominic's Vettucaud in the north, and Kochuthura in the south; towards its west is the Arabian Sea. While the border with Menamkulam is the Parvathi Puthannaar canal, the border with Kochuthura is the Rajiv Gandhi Nagar road. The entire village is flat at sea level, and the ground near to the coast is made of tan-coloured beach sand. This is in stark contrast to the rest of the village, where the ground is made of white sand, where, till the developments of the late 1990s, large amounts of a medicinal herb with white flowers called ''Thumba'' grew in abundance, hence the name. TERLS dedicated to the United Nations on 2 February 1968. Overview Thumba became well-known to the outsiders after the establishment of Thumba Equatorial Rocket Launching Station (TERLS), which was the first of that kind in India. TERL ...

Solid Propellant
A propellant (or propellent) is a mass that is expelled or expanded in such a way as to create a thrust or other motive force in accordance with Newton's third law of motion, and "propel" a vehicle, projectile, or fluid payload. In vehicles, the engine that expels the propellant is called a reaction engine. Although technically a propellant is the reaction mass used to create thrust, the term "propellant" is often used to describe a substance which is contains both the reaction mass and the fuel that holds the energy used to accelerate the reaction mass. For example, the term "propellant" is often used in chemical rocket design to describe a combined fuel/propellant, although the propellants should not be confused with the fuel that is used by an engine to produce the energy that expels the propellant. Even though the byproducts of substances used as fuel are also often used as a reaction mass to create the thrust, such as with a chemical rocket engine, propellant and fuel are two ...

Military Science
Military science is the study of military processes, institutions, and behavior, along with the study of warfare, and the theory and application of organized coercive force. It is mainly focused on theory, method, and practice of producing military capability in a manner consistent with national defense policy. Military science serves to identify the strategic, political, economic, psychological, social, operational, technological, and tactical elements necessary to sustain relative advantage of military force; and to increase the likelihood and favorable outcomes of victory in peace or during a war. Military scientists include theorists, researchers, experimental scientists, applied scientists, designers, engineers, test technicians, and other military personnel. Military personnel obtain weapons, equipment, and training to achieve specific strategic goals. Military science is also used to establish enemy capability as part of technical intelligence. In military hist ...

Nuclear Chemist
Nuclear chemistry is the sub-field of chemistry dealing with radioactivity, nuclear processes, and transformations in the nuclei of atoms, such as nuclear transmutation and nuclear properties. It is the chemistry of radioactive elements such as the actinides, radium and radon together with the chemistry associated with equipment (such as nuclear reactors) which are designed to perform nuclear processes. This includes the corrosion of surfaces and the behavior under conditions of both normal and abnormal operation (such as during an accident). An important area is the behavior of objects and materials after being placed into a nuclear waste storage or disposal site. It includes the study of the chemical effects resulting from the absorption of radiation within living animals, plants, and other materials. The radiation chemistry controls much of radiation biology as radiation has an effect on living things at the molecular scale. To explain it another way, the radiation alters th ...
