Biography

Born on 15 June 1961, Ravindra Kumar did his B.E. (Hons) in Mechanical Engineering from BITS Pilani, and continued there to earn an M.Sc. (Hons) in Physics in 1983. Subsequently, he enrolled for doctoral studies at the Indian Institute of Technology, Kanpur from where he secured a PhD in 1990. His post-doctoral work was also at IIT Kanpur and in 1992, he joined Tata Institute of Fundamental Research where he is a senior professor of the Department of Nuclear and Atomic Physics, heading UPHILL (Ultra-short Laser Pulse High Intensity Laser Laboratory.

Legacy Kumar is known to have established UPHILL (Ultra-short Laser Pulse High Intensity Laser Laboratory), a centre for advanced laser experiments at Tata Institute of Fundamental Research. Here, he heads a group of scholars and researchers who are involved in studies related to laser-matter interactions. He is reported to have worked on the generation of megagauss magnetic pulses using ultrafast laser pulses and his group observed the turbulent magnetic fields created by instabilities of the high current electron beams driven by the laser pulse for the first time. Nanoparticle coated surfaces and pendular states of molecules are two of the other areas of his research. His studies have been documented by way of a number of articles and the online article repository of the Indian Academy of Sciences has listed 75 of them. He has also guided a number of students in their doctoral studies. He is a member of the Optical Society of America and sits in the International Committee on Ultra-High Intensity Lasers of the International Union of Pure and Applied Physics. He is also a life member of Indian Society for Mass Spectrometry, Indian Society of Atomic and Molecular Physics, Plasma Science Society of India and Indian Laser Association. Plenary or invited lectures delivered by him include the lecture on Extreme Light, Extreme States of Infosys Science Foundation in March 2016.

Awards and honors Ravindra Kumar was awarded the B. M. Birla Science Prize by B. M. Birla Science Centre in 2000. The Council of Scientific and Industrial Research awarded him the Shanti Swarup Bhatnagar Prize, one of the highest Indian science awards in 2003. The Indian Academy of Sciences elected him as a fellow in 2004 and he received the Salute Mumbai Award in 2005. The Department of Atomic Energy honored his work during the period between 2006 and 2011 with DAE-SRC Outstanding Research Investigator Award and the elected fellowship of the Indian National Science Academy reached him in 2008. The Infosys Science Foundation presented the Infosys Prize to him in 2015. In 2017, Kumar became a laureate of the Asian Scientist 100 by the Asian Scientist.

Worked examples

Example 1 — a first encounter with G. Ravindra Kumar

Start with the simplest possible case. Write down what G. Ravindra Kumar claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 G. Ravindra Kumar 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 G. Ravindra Kumar 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 G. Ravindra Kumar

In research: G. Ravindra Kumar appears in physics 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 G. Ravindra Kumar 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: G. Ravindra Kumar is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1961 births, Academic staff of Tata Institute of Fundamental Research, BITS Pilani alumni, so understanding it makes those chapters shorter.
In everyday life: Look for G. Ravindra Kumar 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.
