Reference excerpt

Govindan Sundararajan is an Indian materials engineer, known for his contributions in the areas of Surface Engineering and Ballistics. The Government of India honoured him, in 2014, by awarding him the Padma Shri, the fourth highest civilian award, for his contributions to the fields of science and technology.

Biography Govindan Sundararajan was born in Andhra Pradesh on 11 December 1953. He graduated in metallurgical engineering from the Indian Institute of Technology, Madras in 1976, followed by master's degree (MS) in 1979 and doctoral degree of PhD from the Ohio State University, Columbus, USA in 1981. He returned to India the next year to start his career as a scientist with the Defence Metallurgical Research Laboratory (DMRL), in 1982. In 1997, he joined the International Advanced Research Centre for Powder Metallurgy and New Materials (ARCI) as its Director and currently holds the position.

Legacy

Sundararajan is credited with extensive research on tribological behavior of materials and composites. An expert in specialty coatings, Govindarajan's research findings have assisted in developing advanced thermal spray coating for the Kaveri Engine Programme (GTRE GTX-35VS Kaveri). He has been instrumental in the establishment of many advanced research facilities such as the ARCI Center for Laser Processing of Materials, ARCI Surface Engineering Division, Center for Fuel Cell Technology, Chennai and the ARCI Centre for Sol-Gel Nanocomposite Coatings, all of which bear testimony to Govindarajan's design and fabrication abilities. It was under his leadership, the Advanced Materials Technology Incubator (AMT), an ARCI venture which at present, is home to five companies, was established. He is reported to have been successful in commercializing the technologies on behalf of ARCI, all the five companies under the Incubator programme being beneficiaries of technology transfer from ARCI. Govindarajan is credited with many inventions for which he holds 5 patents.

Awards and recognitions Govindan Sundararajan is a winner of many awards and honours including the Government of India honour of Shanti Swarup Bhatnagar Prize in 1994. He has also received Best Metallurgist award in 1995 and the FICCI award for Materials Science in 2004. Institutions such as Indian Academy of Sciences in 1992, Indian National Science Academy in 1996, Indian National Academy of Engineering in 1999, National Academy of Sciences in 2002, Indian Institute of Metals in 2002, and ASM International in 2005, honoured Sundararajan with fellowships. He has also received J. C. Bose fellowship during 2006–2011. The Government of India honored Sundararajan again with the Padma Shri by including him in the 2014 Republic Day Honours.

Worked examples

Example 1 — a first encounter with Govindan Sundararajan

Start with the simplest possible case. Write down what Govindan Sundararajan claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, 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 Govindan Sundararajan 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 Govindan Sundararajan 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 Govindan Sundararajan

In research: Govindan Sundararajan appears in engineering 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 Govindan Sundararajan 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: Govindan Sundararajan is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1953 births, 20th-century Indian engineers, Engineers from Andhra Pradesh, so understanding it makes those chapters shorter.
In everyday life: Look for Govindan Sundararajan 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.
