Reference excerpt

Sunil Kumar Singh (born 1971) is an Indian geochemist, a professor at the Physical Research Laboratory on lien and serving as Director of the National Institute of Oceanography, India since 2017. He is known for his studies on low temperature elemental and isotope geochemistry and his researches are reported to have assisted in widening the understanding of the evolution of the Himalayas and biogeochemical cycling in the Indian Ocean. His studies have been documented in several peer-reviewed articles; Google Scholar, an online repository of scientific articles, has listed 99 of them respectively. Singh, born on 16 March 1971, has done his education BSc, MSc(Tech), at Banaras Hindu University and PhD in geology at Physical Research Laboratory and MS University, Vadodara. He is a former Scientific Steering Committee member and the incumbent member of the Data Management Committee of GEOTRACES, an international forum for research on the marine biogeochemical cycles of trace elements and isotopes. As a collaborator, he is associated with the Ganga Corridor program, an initiative of the Indian Institute of Technology, Kanpur and the Department of Science and Technology, India. He was the co-coordinator of Weathering and Erosion session of the 2016 Goldschmidt conference held in Yokohama. He is a recipient of the National Geoscience Award and an elected fellow of the Indian Academy of Sciences, the National Academy of Sciences, India, and the Indian National Science Academy. The Council of Scientific and Industrial Research, the apex agency of the Government of India for scientific research, awarded him the Shanti Swarup Bhatnagar Prize for Science and Technology, one of the highest Indian science awards for his contributions to Earth, Atmosphere, Ocean and Planetary Sciences in 2016.

Worked examples

Example 1 — a first encounter with Sunil Kumar Singh (geochemist)

Start with the simplest possible case. Write down what Sunil Kumar Singh (geochemist) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, 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 Sunil Kumar Singh (geochemist) 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 Sunil Kumar Singh (geochemist) 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 Sunil Kumar Singh (geochemist)

In research: Sunil Kumar Singh (geochemist) appears in chemistry 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 Sunil Kumar Singh (geochemist) 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: Sunil Kumar Singh (geochemist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1971 births, Fellows of the Indian Academy of Sciences, Indian geochemists, so understanding it makes those chapters shorter.
In everyday life: Look for Sunil Kumar Singh (geochemist) 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.
