Reference excerpt

Muthusamy Lakshmanan (born 25 March 1946) is an Indian theoretical physicist currently working as Professor of Eminence at the Department of Nonlinear Dynamics of Bharathidasan University. Presently he is the DST-SERB National Science Chair awarded by the Science and Engineering Research Board, Department of Science and Technology. He has held several research fellowships which included Raja Ramanna fellowship of the Department of Atomic Energy, Alexander von Humboldt fellowship, Japan Society for the Promotion of Science fellowship, Royal Society Nuffield Foundation fellowship, and NASI-Senior Scientist Platinum Jubilee Fellowship. On 15 August 2021, he was conferred with the Dr. A. P. J Abdul Kalam Award by the Government of Tamil Nadu. Known for his research on nonlinear dynamics and for the development of Murali-Lakshmanan-Chua (MLC) Circuit, Lakshmanan is an elected fellow of all three major Indian science academies – Indian Academy of Sciences, Indian National Science Academy and 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 physical sciences in 1989.

Biography Muthusamy Lakshmanan was born on 25 March 1946 in Pollachi, in the Coimbatore district of the south Indian state of Tamil Nadu. He graduated in science from NGM College in Pollachi in 1966 and earned his master's degree in physics (MSc) at Madras Christian College of the University of Madras in 1969. His post-MSc studies in theoretical physics were also at the University of Madras, completed with a first rank in 1970. He joined the university as a research assistant the same year. Simultaneously, he pursued his doctoral studies, supervised by P. M. Mathews, to secure a PhD in nonlinear dynamics in 1974. Taking a sabbatical from university service, he did his post-doctoral studies first at the University of Tübingen as an Alexander von Humboldt fellow during 1976–77, and then at the Eindhoven University of Technology from 1977 to 1978. On his return to India, he rejoined University of Madras at their Post-Graduate Centre at Tiruchirapalli as a reader of physics, and held this post until 1982 when he moved to the physics department of Bharathidasan University as a reader. He was promoted as a professor in 1984, after which he headed the department of physics (1994–2006) as well as the Centre for Nonlinear Dynamics (CNLD) (1992–2006). In between, he served as an honorary professor at S.N. Bose National Centre for Basic Sciences from 1989 to 1994. During his university service, Lakshmanan had several stints abroad: at the Institute of Science and Technology of the University of Manchester during 1979–80 as Royal Society Nuffield Foundation fellow, as a guest scientist at Uppsala University in 1981, and as a Japan Society for the Promotion of Science fellow at Kyoto University from 1984 to 1985. He also filled short-term assignments at institutions such as the International Centre for Theoretical Physics (1975 and 1986), Utrecht University (1975), Indian Institute of Science (1976), NATO Advanced Study Institute (1980), University of Melbourne (1980), University of Adelaide (1980), Indian Institute of Technology Madras (1982), Pondicherry University (1988), Centro di cultura scientifica Alessandro Volta (1988), Fudan University (1989), Russian Academy of Sciences (1990), Polish Academy of Sciences (as an INSA exchange fellow – 1991), Royal Society (as an INSA exchange visitor – 1996), University of Turku (1997), and Royal Netherlands Academy of Arts and Sciences (as an INSA exchange visitor – 1996). He superannuated from service in 2006. Post-retirement, he was nominated as a professor of eminence by Bharathidasan University and continued his association with the university as a Raja Ramanna fellow of the Board of Research in Nuclear Sciences (BRNS) of the Department of Atomic Energy (DAE) during 2006–07. After the expiry of the tenure of the fellowship, the Department of Science and Technology selected him as a Ramanna fellow in 2007. In 2011, DAE offered him the Raja Ramanna fellowship for a second term and he continued his research at the university.

Worked examples

Example 1 — a first encounter with Muthusamy Lakshmanan

Start with the simplest possible case. Write down what Muthusamy Lakshmanan 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 Muthusamy Lakshmanan 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 Muthusamy Lakshmanan 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 Muthusamy Lakshmanan

In research: Muthusamy Lakshmanan 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 Muthusamy Lakshmanan 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: Muthusamy Lakshmanan is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1946 births, 20th-century Indian physicists, Academic staff of Kyoto University, so understanding it makes those chapters shorter.
In everyday life: Look for Muthusamy Lakshmanan 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.
