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.

China's attempt to curtail Hong Kong's autonomy: Will it force the people to leave Hong Kong?

The sovereignty of Hong Kong was reverted to China by Britain in 1997. Although it became part of China but enjoyed some autonomy and internal democracy due to the “one country, two systems” arrangement between Britain and with China at the time of handover. This arrangement of autonomy and democratic rights were supposed to last until 2047. However, the Communist Party of China had been pushing for a new security law which would curb the voices of the residents significantly, criminalizing acts of secession, subversion, terrorism or collusion with foreign forces. “This law means that China will have the power to impose its own laws on any criminal suspect it chooses,” says Joshua Rosenzweig, the head of Amnesty’s China team.

This is a part of the agitation that is faced by the Hong Kong residents; the economy is shrinking, the government is more focused on linking the city to the mainland than investing in education and affordable housing, peaceful protests have turned violent and are facing police brutality. This has caused changes in international relations with respect to economy and immigration, and a flurry of Hong Kong residents exploring options to leave the city. Skilled workers are seeking to move out of the city, renewing documents which will provide a pathway to residency in Britain, or ways to emigrate to Taiwan, Canada or Australia.

Britain, which had colonised Hong Kong until 1997, announced that it would extend visa rights for all the people eligible to apply for British National Overseas passport, which includes 3 million people, if China went through with the law. The Chinese foreign ministry said that this move violated international law, and that China reserves the right to take measures they see as necessary.

Taiwan has announced that it will set up an office for those who are planning to leave Hong Kong. Chinese government has said that there has been no stifling of freedoms and providing shelter for “rioters and elements who bring chaos” to Hong Kong would bring harm to Taiwan’s people. The island country had housed Hong Kong’s protesters who feared harsh treatment by the law and enforcement since 2019, with its own history of dissension with mainland China.

USA, on a similar vein, has taken away the special economic status Hong Kong had with them, and that the Chinese plans are a “tragedy.”

Many pro-democracy protesters who were on the radar of Chinese government have started  escaping the country to protect themselves and continue the protests from their adopted countries. The excessive use of brutal force against peaceful protesters led many people to fear for the future of their families for which they started to consider leaving the city . The same fear is also driving more than half of the people within the age group of 18 to 24 towards exploring the option of moving out of Hong Kong..

Even after worldwide criticism, mainland China remains adamant on violating the freedoms of the people of Hong Kong. Amidst a collapsing economy which just lost its preference from a world superpower and living under the constant threat of oppressive actions are driving the well healed parsons to look for greener pastures away from Hong Kong.
