Reference excerpt

Sanjay Puri (born 23 November 1961) is an Indian statistical physicist and a senior professor at the School of Physical Sciences of Jawaharlal Nehru University. Known for his research on non-linear dynamics, Puri is an elected fellow of the Indian Academy of Sciences 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 physical sciences in 2006.

Biography

Born on 23 November 1961 at Rampur in the Indian state of Uttar Pradesh, Sanjay Puri earned a research-based master's degree (MS), guided by K. P. Jain, for his thesis, Theoretical Investigations of Soliton Dynamics in 1982 from the Indian Institute of Technology, Delhi. Moving to the US, he secured another master's degree in physics from the University of Illinois at Urbana-Champaign in 1983 and continued there for his doctoral studies under guidance of Yoshitsugu Oono to secure a PhD in 1987, his thesis being Some Problems in the Dynamics of Spatially Extended Systems.. Returning to India, Puri joined Jawaharlal Nehru University the same year as an assistant professor at the School of Physical Sciences, became an associate professor in 1993 and has been working there as a professor since 2001. During this period, he also had several stints abroad as a visiting professor at institutions such as Johannes Gutenberg University of Mainz, University of Manchester, Cambridge University and Kyoto University.

Legacy

The core areas of Puri's work are in statistical physics and nonlinear dynamics with special focus on pattern formation in nonequilibrium systems. His research is reported to have studied the effects of confined geometries and the role of defects in phase separation dynamics and the work is known to have assisted in a wider understanding of kinetics of phase ordering. Study of granular materials, especially freely-evolving granular gases, was another focal point of his work. Puri's studies have been documented by way of a number of articles and the online article repository of the Indian Academy of Sciences has listed 134 of them. Besides, he has published three books, including Dissipative Phenomena in Condensed Matter: Some Applications, co-authored with Sushanta Kumar Dattagupta and Kinetics of Phase Transitions, an edited work. Puri has also guided several students in their studies and serves as the associate editor of Phase Transitions journal of Taylor and Francis.

Awards and honors Puri, who topped the IIT Delhi examinations in 1982, was a recipient of the Silver Medal of Excellence of the institute. The Indian National Science Academy awarded him the Young Scientist Medal in 1993 and the International Centre for Theoretical Physics selected him as an associate member in 1994. Puri received the N. S. Satya Murthy Memorial Award of the Indian Physics Association in 1994 followed by B. M. Birla Science Prize in 1999. He was chosen for the Homi Bhabha Fellowship in 2003 and for the J. C. Bose National Fellowship of the Department of Science and Technology in 2012. In between, the Council of Scientific and Industrial Research awarded him the Shanti Swarup Bhatnagar Prize, one of the highest Indian science awards in 2006. Puri is also an elected fellow of two of the three major Indian science academies, the Indian Academy of Sciences electing him in 2006 and the Indian National Science Academy fellowship reaching him in 2012.

Worked examples

Example 1 — a first encounter with Sanjay Puri

Start with the simplest possible case. Write down what Sanjay Puri 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 Sanjay Puri 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 Sanjay Puri 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 Sanjay Puri

In research: Sanjay Puri 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 Sanjay Puri 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: Sanjay Puri is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1960 births, Academic staff of Jawaharlal Nehru University, Academic staff of Kyoto University, so understanding it makes those chapters shorter.
In everyday life: Look for Sanjay Puri 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.
