Reference excerpt

Sharat Kumar Roy (27 August 1897 – 17 April 1962) was an American geologist of Indian origin. He took an interest in volcanoes and later was a specialist on meteorites. He worked as a curator of geology at the Chicago Natural History Museum and took part in several expeditions of the Museum. The United States Coast and Geodetic Survey named a peak on Baffin Island as Mount Sharat after him in 1944.

Early life Roy was born in an aristocratic Mahishya family in Shyamnagar, Nadia, Bengal where his father Navin Krishna was an engineer. He moved to Hazaribagh with his family where he went to St. Columba's College and then joined Bangabasi College, Calcutta for his pre-university certificate.

Higher studies and work During World War I, he served in the British Indian Army. He then went to the University of London (1919) along with Raja Bose, son of the geologist Pramatha Nath Bose. He moved to the US and then joined the University of Illinois from where he received a BS (1922) and an MS (1924). He worked for some time in the New York State Museum, Albany before joining the Field Museum of Natural History as an assistant curator of invertebrate paleontology. Roy joined the Rawson-MacMillan expedition of 1927-28 to Labrador and Baffin Island and collected fossils from Silliman's Fossil Mount and described a number of new fossil taxa. He also became the first person of Indian origin to go on polar expeditions to North Pole. From 1942 to 1946 he served in the US Air force in the India-Burma theatre (posted for a while at Roosevelt Nagar, now called Kalyani, and at Dhubulia, Nadia district) and towards the end of the war, he collected Permian brachiopods and geological specimens from the Salt Range. Returning to the Field Museum, he became a chief curator in 1947. He joined trips to Central America to study volcanoes between 1952 and 1961 with a visit in 1957-58 to Europe and India to examine stony meteorites. He received a PhD from the University of Chicago in 1941. In one of his researches, he replicated the claims made by Charles B. Lipman of finding bacteria inside meteorites and demonstrated that they were only the result of contamination after entry into the earth.

Personal life and death

Roy was married to Elsa and lived on South Everett Avenue, Chicago. He died at Billings Hospital. He was a Fellow of the Royal Geographical Society, the Geological Society of London apart from Sigma Xi and Theta epsilon pi.

Worked examples

Example 1 — a first encounter with Sharat Kumar Roy

Start with the simplest possible case. Write down what Sharat Kumar Roy 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 Sharat Kumar Roy 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 Sharat Kumar Roy 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 Sharat Kumar Roy

In research: Sharat Kumar Roy 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 Sharat Kumar Roy 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: Sharat Kumar Roy is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1897 births, 1962 deaths, 20th-century American geologists, so understanding it makes those chapters shorter.
In everyday life: Look for Sharat Kumar Roy 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.
