Retired Prof HC Verma, who made high-school Physics interesting through the problems given in this book (some people don't like its theory :lol: although I do), was awarded the Padma Sri on this republic day. ... (2020-2029)

He also has a few other initiatives which are lesser-known to people:

He has co-founded few initiatives like Daltonganj Sopan for the social upliftment of the children of the economically weaker section living near Indian Institute of Technology Kanpur's campus. According to his website, he is currently working on a book about electrostatics, magnetostatics, and electrodynamics for undergraduate students studying science.

^^^ Thanks for posting this. In addition, I was pleasantly surprised to see a few familiar people ( at least 3 from IIT K alone )...
(Along with the Republic Day, it is also IIT Kanpur’s Diamond Jubilee so this news is celebrated there too)
-- Prof. Sudhir Jain, Director, IIT Gandhinagar and formerly a faculty of IIT Kanpur has been awarded the Padma Shri.
As founding Director, he has been instrumental in shaping IIT Gandhinagar.
Dr. Jain has experimented with numerous ideas in the curriculum, student affairs, faculty recruitment and faculty management and has conducted extensive research in the area of earthquake engineering. Heartiest congratulations to him!

-- (As posted above) Harish Chandra Verma, alumnus & retired Professor and now associated as an Adjunct faculty, has been awarded the Padma Shri. He epitomises outstanding teaching ethos of IIT Kanpur.

Prof. Verma was also instrumental in setting up Shiksha Sopan, an NGO that helps children from underprivileged background in their education. Through Shiksha Sopan’s scholarship program, many children have been able to access quality education.

Prof. Verma is a well-known name in the field of Indian education, thanks to his physics books which continue to be widely used in schools and colleges. Apart from his research on nano fabrication using focused ion beam, magnetism in graphite on irradiation by ion beam and nanosize magnetic materials, Prof. Verma has worked tirelessly on developing simple experiments to make science more interesting for school children. He has developed more than 600 physics experiments which can be used by teachers as DEMOs in their classrooms and he has also produced a set of 45 video lectures in Hindi for the school level.

--- Also Vashisht Narayan Singh, an ex-professor of IITK, (Also of TIFR) who passed away last year also been awarded Padma Shri along with Prof HC Verma and Prof Sudhir Jain. ..

There are few other names in related fields which I am very happy that they are being recognized ..

L&T builds cryostat for USD 20 bn global fusion projec.

Engineering and construction giant Larsen & Toubro on Tuesday said it has achieved a major milestone under 'Make in India' initiative by building a cryostat for USD20 billion global fusion project. The final assembly or top lid sectors of the cryostat, a key part of the world's largest nuclear fusion reactor being built in France, were dispatched on Tuesday from the company's Hazira manufacturing complex in Surat district in Gujarat.

Larsen & Toubro (L&T) in 2012 chosen by ITER-India to manufacture and install cryostat - a vacuum pressure vessel made of 3,850 tonnes of stainless steel. L&T Group Chairman AM Naik termed it a "moment of pride for India and Larsen & Toubro".

"The heavy engineering arm of L&T, India's leading engineering, construction, technology, manufacturing and financial services conglomerate, has flagged-off the most complex and final assembly of cryostat, the largest stainless-steel, high-vacuum pressure chamber in the world. "This is an important milestone in the global nuclear fusion arena as well as a moment of pride for the Make in India initiative," the company said in a statement.

The cryostat assembly weighing 650 tonne is to be installed with other cryostat segments for ITER (International Thermonuclear Experimental Reactor) in a reactor pit in southern France.

L&T has already delivered the base section, the lower cylinder and the upper cylinder for the cryostat. The cryostat's function is to provide cooling to the fusion reactor and to keep very high temperatures at its core under control. A virtual flag-off ceremony of the final assembly was held at the company's Hazira manufacturing complex.

Dr Bernard Bigot, Director-General, ITER Global, KN Vyas, Chairman Atomic Energy Commission, India, UK Baruah, Project Director, ITER-India, V K Saraswat, Member, NITI Aayog, A M Naik, Group Chairman L&T and SN Subrahmanyan, CEO & MD, L&T, joined the ceremony virtually.

Naik said: "It is a moment of pride for India and for L&T in particular as we have gathered to flag-off the last section of the Cryostat Vessel for the most ambitious clean energy project limitless carbon free energy that will power the future. L&T has always been proud of this global collaborative research to build a greener planet."

Subrahmanyan the company has used innovative and digital manufacturing techniques to ensure uninterrupted supply of high-precision assemblies to ITER. "This will further pave a way for the installation of cryostat at the project site in France and eventually lead to the demonstration of large scale feasibility of fusion power. It has empowered India to tread towards Atma Nirbhar Bharat by acquiring knowledge in this highly specialised field of science and technology,” Subrahmanyan added.

Anil V Parab, Executive Vice President and Head, L&T Heavy Engineering told PTI that ITER is a USD 20 billion project and India is contributing 9 per cent of the project component.

"With the supply of the Top Lid sector, we have successfully completed our India scope of the project ahead of the schedule. The fabrication of these components has been an engineering marvel both in terms of its massive size and its stringent quality standards.”

The project scope for L&T Heavy Engineering is divided into three aspects, the company said.

L&T's Heavy Engineering business won this prestigious contract from ITER India, a wing of Department of Atomic Energy, for the ambitious mega scientific project, conducted in collaboration of seven elite countries, including India, and with a project outlay of around USD 20 billion.

This is a *major* contribution from Indian Scientists

The PIP-II project at Fermilab includes construction of a 215-meter-long particle accelerator that will accelerate particles to 84% of the speed of light. The new particle accelerator will enable Fermilab to generate an unprecedented stream of neutrinos.

This is a major project by USA with international cooperation from India and also UK, Poland, France and Italy.

Remembering Mahalanobiss (Prasanta Chandra Mahalanobis) - Who was friend/classmate of Ramanujan in his Cambridge days
Mahalanobis was “a physicist by training, a statistician by instinct and an economist by conviction” - A nice article written by Atanu-da

Some excerpts IMO relevant today -

Bengal’s famine survey reminds us that we need estimates of the millions who will lose jobs or livelihoods and of the hundreds of millions whose economic conditions will deteriorate in today’s COVID-19-hit India. The extent of feasibility, success and problem of online access, for example, also needs to be properly estimated in this new dawn.

Mahalanobis is perhaps more relevant today when the accuracy of different sorts of data — from economic data to COVID-19 data — is under the scanner. Starting from the first area sample in the whole world for jute forecast in 1934, Mahalanobis built up a strong and trustworthy statistical heritage in India through his tireless efforts over the years, supplemented by his efficiency, wisdom, leadership, innovative ideas and brilliance. Mahalanobis envisaged large-scale sample surveys as statistical engineering rather than pure theory of sampling. He was instrumental in establishing the National Sample Survey (NSS) in 1950 and the Central Statistical Organization in 1951.

Mahalanobis was very careful about data accuracy in his surveys. In Kautilya’s Arthashastra, there is mention of the need for cross-checking by an independent set of agents for data collection: “Spies under disguise of householders (Grihapatika, cultivators), who shall be deputed by the Collector-General for espionage, shall ascertain the validity of accounts (of Gopas, the village officers and Sthanikas, the district officers) regarding the fields, right of ownership and remission of taxes with regard to houses, and the caste and profession regarding families...” (Chapter XXXV). This, according to Mahalanobis, was the “striking feature in the Arthashastra”. This might have prompted him to have an independent supervisory staff during the conduct of field operations by the NSS for collection of reliable data.

Mahalanobis was “a physicist by training, a statistician by instinct and an economist by conviction”. His initial training in Physics might have made him conscious about errors in measurement and observation. Students even called him the Professor of Counting and Measurement, using the initials of his name. The desire to have built-in cross-checks and to get an estimate of errors in sampling led him to introduce the Inter-Penetrating Network of Subsamples, which is now considered as the curtain-raiser for re-sampling procedures like Bootstrap, a revolutionary concept of statistics indeed.
At the end of his 1946 article in The Asiatic Review, Mahalanobis wrote: “Statistics are a minor detail, but they do help.” This is an eternal truth. What Mahalanobis didn’t spell out is that one needs a top statistician for listening to the heartbeats of data and for framing data-based policy decisions for human welfare and national development. And unfortunately, there’s no one to fill Mahalanobis’s shoes, even about half a century after his demise.

Just to share a small fact, which i believe (most probably) is known to all gurus here. On several articles i have read that Subramanian Swamy was an student of Mahalanobiss at ISI Kolkata & they had quite bitter professional relationship. Swamy jee & Mahalanobiss jee had confrontation of opinions on several occasions.

Sorry for the OT.
