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.

The case of Huawei: How that impacts Canada-China relations

In December 2018, Meng Wanzhou, the Chief Financial Officer for Huawei, a China-based tech company which is dominating the telecom supplies, was arrested in Vancouver, Canada on her flight stop to Mexico. This was done on a request from the USA with whom Canada has an extradition treaty. She was sought by the USA for allegedly dealing with Iran using an American banking system in spite of the sanctions placed on Iran by the country, in 2013. In May, Wanzhou lost the legal challenge to the extradition process, meaning that they will go ahead with the extradition proceedings.

Within days of Wanzhou’s arrest, two Canadian citizens in China were arrested on alleged accounts of spying. This is seen as a retaliation for the Wangzhou arrest by the Canadian Prime Minister Justin Trudeau, who says that there is a direct link between Wanzhou’s arrest and those of Michael Spavor and Michael Kovrig,  the Canadians who are detained in China. Though China has been tight-lipped about the link between the two, these two incidents are often raised jointly by the Chinese spokesperson. David Mulroney, former ambassador for Canada to China, has said that the officials in Beijing are mirroring the ongoing extradition case to that of the detained Canadians.

Although Mr. Trudeau has in the past repeatedly emphasized the need for good relations with China, and has enthusiastically worked on them to the point of agreeing to discuss a Canada-China extradition treaty. But the China-Canada relations already started souring much before the arrest after a trade deal fell through in 2017. Many major carriers in the country, some of which have been outspoken in their support of Huawei, have decided to shun the company and opt for western alternatives instead. One of them, Bell Mobility, even announced that it will use equipment from its Finnish rival, Nokia.

Huawei is considered a symbol for China’s technological prowess, and the arrest is seen by the Chinese Communist Party as an attack on its symbol of technological achievement. The Chinese state-owned newspaper the Global Times calls the act a “political persecution launched by the US, with the intention to contain China’s high-tech development.” The China Daily also criticized the court ruling as unfair and potentially harmful in mending the Canada-China relations.

There has also been a backlash from legal experts and family members of the detained Canadians on the Canadian policy of letting the extradition charges proceed and not going with a prisoner swap. Mr. Mulroney, however, feels that it would legitimize “hostage diplomacy”, which would put at risk all traveling Canadians for arbitrary arrests to gain political leverage. There is a stark difference between the condition of the hostages and that of Meng Wanzhou, for while the two prisoners spend their days in small cells in isolation, interrupted by interrogation and bland meals, Wanzhou lives in her Vancouver mansion, being happy about the fact that she can spend more time reading and oil painting, now.

The Canadian government is also claiming that it has to let the extradition process go on without political interference as to not compromise the independent, legal decision of surrendering the Huawei CFO. Mr. Mulroney has said that “it wouldn’t be the right thing to do. It would compromise the integrity of both our democracy and our justice system,” and that their values need to count for something. Brian Greenspan, a Toronto lawyer with experience on extradition cases, has said that the government has the power to withdraw from the extradition case, and that the lessons from a previous case in which political pressure affected an international case, are being applied wrongly here.

There are many sides to this tension, complicated by previous feuds, economic decisions, the detentions of the Canadians and Wanzhou and the difference between the political and the legal, and the many opinions on whether it should be that way.
