Reference excerpt

Rengaswamy Ramesh (1956–2018) was an Indian climatologist, oceanographer, a former Prof. Satish Dhawan Professor at the Physical Research Laboratory and a senior professor at the National Institute of Science Education and Research, Bhubaneswar. He was known for paleo-climatic and paleo-oceanographic studies and was an elected fellow of all the three major Indian science academies viz. Indian National Science Academy, Indian Academy of Sciences, and the National Academy of Sciences, India as well as of The World Academy of Sciences. 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 1998.

Biography

R. Ramesh, born on 2 June 1956 in the south Indian state of Tamil Nadu, did his graduate studies in physics (1976) at the University of Madras and completed his master's degree at the same university in 1978. Enrolling for his doctoral studies under the supervision of Kunchithapadam Gopalan of Physical Research Laboratory (PRL), he secured a PhD from Gujarat University in 1984 and did his post doctoral studies at his mentor's laboratory during 1985–86. He joined the Planetary and Geosciences Division of PRL as a research associate in 1987 and has served the institution in such various capacities as a Scientist-Grade D (1987–94), Reader (1994–98), Associate Professor (1999–2001), Professor (2002–07) and Senior Professor (since 2008) and holds the position of a Foundation for GLocal Science Initiatives (FGSI) Outstanding Scientist. In between, he had a short stint at Scripps Institution of Oceanography during 1992–93 as a visiting research associate, working under the guidance of Devendra Lal. He died on 2 April 2018, at the age of 61.

Legacy Ramesh is known to have contributed to the reconstruction studies of paleo-climatic and paleo-oceanographic conditions of the Indian Ocean. He is credited, along with S. K. Bhattacharya and Kunchithapadam Gopalan, with the establishment of a Stable Isotope laboratory for the first time in India. At the laboratory, he applied stable isotope methodology to study tree-rings, corals, peat deposits, speleothems, lake sediments and marine sediments and his studies assisted in widening the knowledge of the monsoons for the past 35 kiloannum. He developed equations for the calculation of past temperatures and rainfall using stable isotope ratios and prepared high resolution documentation of the monsoon changes during the Holocene epoch. His studies have been detailed in several peer-reviewed articles; ResearchGate and Google Scholar, two online repositories of scientific articles, have listed 208 and 267 of them respectively. He was one of the lead authors of the book, Climate Change 2013: The Physical Science Basis, a 1552-page compilation of reports of the Working Group I of the Intergovernmental Panel on Climate Change, published by Cambridge University Press in 2014. He has mentored 15 scholars in their doctoral studies who were also trained by him in stable isotope methodology. He is the project director of the National Program on Palaeoclimate studies of the ISRO-Geosphere Biosphere Programme (GBP) and sits in the Research Council of the National Geophysical Research Institute as an external member.

Awards and honors Ramesh, a National Merit Certificate holder of Ministry of Education and Social Welfare in 1972, received the All India Bengali Literary Conference Medal in 1973. He was selected for the Jawaharlal Nehru Memorial Fund Fellowship in 1976 for his project on The Life and Work of Professor Sir C. V. Raman and the Young Scientist Medal of the Indian National Science Academy reached him in 1987. The Council of Scientific and Industrial Research awarded him the Shanti Swarup Bhatnagar Prize, one of the highest Indian science awards in 1998. The Indian Academy of Sciences elected him as its fellow in 1996 and the other two major Indian science academies, the Indian National Science Academy and the National Academy of Sciences, India followed suit in 2001 and 2002 respectively. He received the TWAS Prize in 2006; TWAS honored him again in 2007 with an elected fellowship. The Indian Space Research Organization awarded him the Lifetime Achievement Award in 2016. The Intergovernmental Panel on Climate Change listed Ramesh as one of the scientists who contributed to reports of the IPCC, which was awarded the 2007 Nobel Peace Prize. He is also a recipient of the Jagirdar of Arni Gold Medal and the Professor P. E. Subrahmanya Ayyar Gold Medal. The list of award orations and plenary speeches delivered by Ramesh includes the 2011 K. R. Ramanathan lecture of the Indian Geophysical Union and the address on Oceanic nitrogen cycling: new results based on isotopic tracers of 2013 held at the K.R. Ramanathan Auditorium of the Physical Research Laboratory.

Worked examples

Example 1 — a first encounter with Rengaswamy Ramesh

Start with the simplest possible case. Write down what Rengaswamy Ramesh claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, 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 Rengaswamy Ramesh 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 Rengaswamy Ramesh 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 Rengaswamy Ramesh

In research: Rengaswamy Ramesh appears in earth science 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 Rengaswamy Ramesh 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: Rengaswamy Ramesh is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1956 births, 20th-century Indian earth scientists, Fellows of The World Academy of Sciences, so understanding it makes those chapters shorter.
In everyday life: Look for Rengaswamy Ramesh 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.
