Reference excerpt

Hanumant Shankar Sawant (13 August 1939 – 27 December 2025) was a radio astronomer and one of the pioneers of the Brazilian solar radio astronomy. He was the key scientist behind the concept, design, and installation of the Brazilian Decimetric Array (BDA). Under his leadership, an outstanding group in radio astrophysics was built at the National Institute for Space Research (INPE) in Brazil.

Early life and education Hanumant Sawant was born at Pune, India, in 1939. He received a BSc degree in Electronics and Communications Engineering from the University of Bombay in 1964, an MSc in Physics in 1971 from Ahmedabad University, and a PhD in Physical Sciences from the Physical Research Laboratory (PRL) in 1977. He was at the Department of Astronomy of the University of Maryland (1978–1979) and the Space Science Laboratory of the University of California, Berkeley, USA (1980–1981). In 1982, he became an Associate Researcher of the National Institute for Space Research (INPE) in Brazil. He became Project Director of the BDA in 2002 and retired from INPE in 2015.

Major contributions His main contributions involved observational and theoretical precursor studies of fine structures in solar noise storms at decametric frequencies and high-energy solar flares, in collaboration with leading scientists such as R.V. Bhonsle, S.K. Alurkar, S.S. Degaonkar, M. Kundu, P. Kaufmann and S.R. Kane. In 1982, he participated in the innovative investigation on the interplanetary effects of solar flares that occurred in 1979; in 1984, he published the results in partnership with S.R. Kane and A. Hewish, the Nobel Prize winner in physics in 1974. This was pioneering work in the scientific field that is now known as space weather. He was the lead researcher for the development of several instruments in solar radio astronomy: ROI Millimeter Radiometer (18–23 GHz) at the Itapetinga Radio Observatory (Atibaia, SP), the Decimetric Solar Spectrometer (1.2-1.7 GHz), the Brazilian Solar Spectroscope (BSS) (1.0-2.5 GHz), and the Brazilian Decimetric Array (BDA), for which he served as General Coordinator from 2001.

Personal life Prof. Hanumant Sawant was married to Ratna Sawant and resided in São José dos Campos, state of São Paulo, Brazil. He had one daughter, Vidula Sawant, and one son, Abhijit Sawant (married to Sandra). He was the grandfather of Kyle, Enzo, and Enya. Sawant died on 27 December 2025.

Worked examples

Example 1 — a first encounter with Hanumant Shankar Sawant

Start with the simplest possible case. Write down what Hanumant Shankar Sawant claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Hanumant Shankar Sawant before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Hanumant Shankar Sawant ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Hanumant Shankar Sawant

In research: Hanumant Shankar Sawant appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Hanumant Shankar Sawant in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Hanumant Shankar Sawant is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1939 births, 2025 deaths, Brazilian astronomers, so understanding it makes those chapters shorter.
In everyday life: Look for Hanumant Shankar Sawant outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
