As he witnessed the first detonation of a nuclear weapon on July 16, 1945, a piece of ancient Scripture “Bhagwad Geeta” ran through the mind of Robert Oppenheimer: “Now I am become Death, the destroyer of worlds”. Oppenheimer, alongside the likes of Richard Feynman, Enrico Fermi, George Gamow, was part of the star-studded Physicist squad behind the Manhattan Project.

The biggest implications drawn from the end of WW2 for many might have just been the incoming power Struggle between the US and Soviet Union, but for your average American it went to a great length to show that Physicists form a breed of people who can build dangerously effective technology.

That fact, however, would have been evident to anyone with a brisk walk through Human History itself. Physicists have arguably provided the most significant contributions to the Technological Development of our race. From Archimedes building light reflectors to save the Greek Army from Roman Infiltration to the large-scale Ballistic Missile systems made during WW-II, weaponry technology has been highly influenced by physicists in every generation.

But mere list of armaments cannot do justice to the role played by Physics Research in Technological Developments of our society. To get a feel for that, let’s go back to the fathers of Modern Physics as we know it; Sir Isaac Newton and Galileo Galilei. Galileo had his long list of achievements in creating cutting edge technology of the day, ranging from Telescopes to Thermometers & the Magnetic Compass. Sir Isaac for his part was the reason behind the advent of the Industrial Revolution in Great Britain!

The simple Atwood Machines which have today become mainstay material taught to College Freshman and High School Seniors worldwide, were actually the kind of mechanical models on which the large-scale Factory Machines were built. Newton’s laws kickstarted the modern Technological Revolution and ever since then, Physics has been a constant source of inspiration behind all Technology.

The great pioneers in the field “Natural Philosophy” (the physics of today) after Newton continued the trend which their illustrious predecessor had started. The seminal works on Thermodynamics by the likes of Lord Kelvin, Ludwig Boltzmann, James Clerk Maxwell etc. played the decisive part in creating automobile engines and really any technology which dealt with heat (Spoiler Alert- There were a lot of them!). Maxwell’s work on the famous equations on Electromagnetism now named after him played the most significant part in the mission of making Electricity available to everyone (a conquest now just famously remembered for the fight between Nikola Tesla and Thomas Edison).

While one can point out that Theoretical works cannot lead to new Technology on their own, that assertion is only the half-truth. Sure, building technology on the basis of theoretical physics is mostly down to the Engineers, but one cannot underestimate the effect new theoretical developments and their possible uses have on the construction of new technologies. After all, if one was not able to understand the principles of the conversion of mass to energy or Electric & Magnetic Fields are coupled to each other, then expecting the construction of Nuclear Reactors and virtually all Electric Tech today would have been off the table.

So one might ask, what are the new theoretical ideas which can guide the next leap forward technologically? Well, no one can be quite sure of the form which technology will take in even a couple of decades (who would have thought that Server systems designed for efficiently using giant Data in CERN would one day be heavily used for making memes!).

I would go as far as to say that we have not yet completely exhausted the technological possibilities of the Special Theory of Relativity itself, the most prominent example of game changing technology based on that has been GPS Communication systems. One can hence fail to even imagine the kind of technological (and Industrial) progress technologies built on the revealing concepts from General Relativity and Quantum Mechanics can bestow upon us (I’m even refraining to comment on the Quantum Field Theoretic parts!).

Whatever that physics will lead us to is a mystery time will be most suited to answer, but one can see the effects of Quantum Mechanics in the next Computational Revolution itself; Quantum Computing. To put into perspective the extent of development Quantum Computing can bestow upon us, consider the following.

Computational devices today, which are stronger than the computers which put humans to the moon, are fundamentally built upon binary bit systems. From generating Big Bang like Energies in CERN and reaching past Saturn, to making all the knowledge available to everyone has been done in two bits. While Quantum Computers, which are being vividly researched on, can work with virtually infinite bits ! So, hold on tight as exciting new physics promises some large-scale changes on our Civilization as a whole.

India’s neighbours drifting towards China: Has PM Modi’s “Neighbourhood First” policy failed?

Back in 2014, when BJP came to power in India under the leadership of Narendra Modi, he invited the heads of government from Nepal, Bangladesh, Pakistan, Afghanistan, the Maldives, Bhutan, and Sri Lanka to his swearing-in ceremony at the Rashtrapati Bhavan.­ The move set the tone nicely for Modi’s “Neighbourhood First” foreign policy and was hailed by experts and critics alike as a positive step towards bolstering regional connectivity and improving cross border relations. Cut to 2020, and the ongoing China-India conflict has exposed plenty of problems for New Delhi regarding its relations with its neighbouring countries, particularly, Pakistan, Bangladesh, Sri Lanka, and Nepal.

In recent days China has increased its investments in Asia and beyond even as India and the West have watched from close quarters. Most of the investments have revolved around Chinese President Xi Jinping’s Belt and Road (BRI) Initiative , which aims to create a Sino-centric global trading network and sphere of influence. The BRI initiative is a matter of concern particularly for India because of the China-Pakistan Economic Corridor (CPEC) that is perhaps the most important project under the BRI initiative.

India has, traditionally, played a dominant role in economic and political matters concerning most of its smaller neighbours. However, with the BRI initiative, China gradually built up its political ties with countries such as Nepal, Sri Lanka, and Pakistan, while India’s relations with these countries have become less cordial in recent years. Nepal, Sri Lanka, and Bangladesh, who were once considered allies to India appear to have tilted in favour of China.

The changing nature of India’s and China's relation with India’s neighbouring countries was evident in the silence of these countries when there was a serious flare-up on the India-China border. It is important to note that every South-Asian nation except Bhutan has signed on to China’s BRI. Bhutan is still following India’s lead in not joining BRI due to its own border dispute with China, for which India’s support is essential.

Nepalese PM KP Oli had called Indian PM Narendra Modi, on 15th August, India’s seventy-third Independence anniversary. A statement by India’s Ministry of External Affairs stated, “‘The leaders expressed mutual solidarity in the context of the efforts being made to minimise the impact of the Covid-19 pandemic in both countries.” However, in June 2020, the Nepalese Armed Police Force fired upon a group of Indian citizens at the India-Nepal border, killing one person and injuring two others. A third Indian who had been detained was released later. The move came in the aftermath of the Nepalese Parliament declaring the Indian territories of Limpiyadhura, Lipulekh and Kalapani as a part of Nepal.

Historically, India and Bangladesh have maintained close ties with each other. Modi’s rise to power in 2014 had no effect as Bangladesh’s PM Sheikh Hasina continued to maintain relations with India. In June 2015, when Modi visited Bangladesh 22 bilateral agreements were signed, including the resolution to a border issue that had existed since 1947 through a successful land boundary agreement (LBA). India also pledged $5 billion worth of investments in Bangladesh. When Sheikh Hasina visited New Delhi in April 2017, a civil nuclear tripartite pact was signed between India, Russia, and Bangladesh. Under the pact India will play an important role in establishing a nuclear power plant in Bangladesh. Even as late as March 2019, Narendra Modi had launched four projects in Bangladesh.

However, India’s relationship with Bangladesh turned sour post August 2019, when the BJP government implemented the NRC in Assam, a north-eastern Indian state. The process of NRC was meant to identify illegal immigrants from Bangladesh. The 1.9 million people left out in the Assam NRC were a cause of concern for Bangladesh owing to the fear of a sudden influx of people forced out of the Indian state. Bangladesh thus turned to China under its “look East” policy in a bid to reduce its dependence on India. China replaced India to become the top trade partner of Bangladesh in 2015 and has provided assistance to Bangladesh through the BRI via 27 agreements signed on Xi Jinping’s visit to the nation in 2016.

“China is behaving how emerging superpowers generally tend to behave—they try to flex muscles and project power—all of which China is trying to do at the moment," says Happymon Jacob, associate professor of disarmament studies at Jawaharlal Nehru University (JNU). “When that happens, states around that emerging power will either stand up against it (like India) or jump on the bandwagon (like other smaller south Asian countries)."

While China continues to make rapid strides, India is left to wonder as to how to deal with this apparent crisis surrounding its neighbouring countries. Modi’s neighbourhood first policy has certainly failed to deliver the promises it made and relations with most neighbouring countries have worsened over the past six years. New Delhi has missed out on several economic gains that would have strengthened ties with neighbouring countries and thereby would have helped to counter the growing Chinese influence in the region. It remains to be seen as to how India decides to get over this tricky situation and improves its ties with its neighbouring countries.
