Reference excerpt

Thirumalachari Ramasami is a former Indian science and technology secretary. He assumed charge in May 2006. Prior to this assignment, he served as the director of the Central Leather Research Institute, Chennai, India. He is a distinguished researcher and leather scientist. He was awarded India's National Civilian Honour the Padma Shri for excellence in Science and Engineering in 2001 and the Padma Bhushan in 2014. He was awarded the Shanti Swarup Bhatnagar Award, the highest award for science in India, for notable and outstanding research in Chemical Sciences in 1993.

Education He graduated in Secondary School Leaving Certificate (SSLC) from G.S. Hindu High School, Srivilliputtur in 1963, Pre-University from St.Joseph's College, Trichy in 1964, Bachelor and Master of Technology in Leather Technology from the University of Madras in 1969 and 1972, respectively with first rank and Doctor of Philosophy in Chemistry from the University of Leeds, England in January 1976.

Career

Research He carried out postdoctoral research in energy at the Ames Laboratory, Iowa State University USA during 1978–80 and on electron transport phenomena at Wayne State University, Detroit, USA during 1981–83. He was a visiting Fellow at University of Newcastle upon Tyne during 1983–84. He holds 37 patents of which 12 have been commercialised. He has authored more than 220 research publications, eight chapters in books, and numerous general articles.

Director of CLRI He came back to India in 1984 and joined as an assistant director of the Central Leather Research Institute, the world's largest leather research institute.(He said in an interview to RSTV (programme name is "Eureka") that one's achievements should be socially recognised and this can be well achieved on your motherland.) As Director of CLRI, he prepared a vision document for CLRI – CLRI Vision 2005, directed the Leather Technology Mission with 170 projects in 17 states of India, reengineering CLRI, new models for development and measures for collective decision making. Led CLRI in providing cleaner tanning technology options for a group of 764 tanneries in a record time of 12 months. Led the Indian initiative in forecasting colours for Modeurop Congress gaining India, a niche status in the fashion world. India is now preparing the shade card for the world. Galvanized and led CLRI in a growth path since 1996 in the capacity as director. Prepared a vision, mission and action document for leading the growth of CLRI and gaining for India global leadership in leather by way of original publications, IPR generation and technologies delivered. He helped CLRI register a meaningful outcome on Indian Leather Sector during 1996–2004. Dramatic increases in outputs of CLRI have been registered during the Directorship since 1996.

Department of Science and Technology

Ramasami assumed the role of Secretary, Science & Technology in the Government of India since May 2006. The department has sought a fifth extension for him which something that is considered rare at his level in the central government. The department of science and technology bid farewell to its secretary, Dr T Ramasami on 5 May 2014 after he superannuated at the age of 66 years. During his eight years stint at the DST, Dr Ramasami was instrumental in its budget increase that jumped several-fold and launch of many new programs. He was also holding the additional charges as the director general, Council for Scientific and Industrial Research (CSIR).

Worked examples

Example 1 — a first encounter with Thirumalachari Ramasami

Start with the simplest possible case. Write down what Thirumalachari Ramasami 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 Thirumalachari Ramasami 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 Thirumalachari Ramasami 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 Thirumalachari Ramasami

In research: Thirumalachari Ramasami 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 Thirumalachari Ramasami 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: Thirumalachari Ramasami is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1948 births, Fellows of the Indian National Science Academy, Indian civil servants, so understanding it makes those chapters shorter.
In everyday life: Look for Thirumalachari Ramasami 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.
