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.

COVID-19 and Hungary’s steep slide towards Authoritarianism

The Hungarian Prime Minister, Viktor Orban, has used the pandemic of coronavirus to turn Hungary into an authoritarian system. This undermines the fundamental principles of democracy and rule of law in a way that is hard to reconcile as necessary for public health. On 30th March 2020, the Hungarian government passed a bill in the parliament which approved granting his government emergency powers.

Critics have said that the emergency of the coronavirus pandemic has turned Hungarian democracy into a dictatorship. This bill, which turned into a law, diminishes the Parliament’s check on the executive power. This means that elections and referendums will be delayed indefinitely.

Political commentator Zoltan Cegledi told BIRN, “Hungary’s already run as an illiberal democracy, the government’s will to destroy, limit and exhaust democracy is permanent. Its future victims will be the remnants of autonomy. Even before the pandemic threat, they [the government] tried to besiege cultural institutions and representatives while attacking judicial independence.”

The legislation under the law also allows up to five years of imprisonment for anyone who publishes false or misleading information that alarm or agitate the public or undermine the government’s “successful protection”. This also means that it is easy for the executive powers to jail the journalists for doing their job. Political Capital Institute, a Budapest-based think tank also wrote “The remaining checks and balances in Hungary will cease to exist and the country will likely witness a new wave of attacks against the free press,” while analysing the bill.

Crucially, the Bill on Protection Against Coronavirus, now a law, does not have any sunset clause. This means the law allows the government to decide when (or if) to end the state of emergency. Hungary’s democratic opposition said that even though they had concerns over a number of elements in the bill, they were willing to overlook it in the emergency situation as long as the sunset clause was introduced. However, the ruling party had made it clear that it was not willing to back down over the sunset clause.

Lydia Gall, a senior researcher at the Human Rights Watch said that Orban had already “weaponized coronavirus to stoke xenophobia” after claiming that coronavirus was imported to Hungary by Iranian students.

The question now arises is why Orban is doing this? There are two reasons. One, this labels the opposition as the “supporters of the coronavirus”, instead of supporters of the people, which will win his government the political debate in advance. Two, Orban sees this as the perfect time for a power grab. Every country is dealing with how to save the lives of its citizens and avoid a total economic collapse- this makes the country more inward-looking, which means that the foreign policy, in general, becomes less important and human rights and the rule of law in other countries become issues of less importance for most politicians and citizens, even though that should not be the case. When there is a death threat, the citizens of a country have a more narrow view. This is how Orban’s strategy of a power grab would work perfectly in the time of an emergency like a pandemic. Rights groups and government critics have said that while it is clear that coronavirus brings extraordinary challenges, there need to be checks and balances in place for the government, especially given Orban trying to challenge the democracy of Hungary since the past ten years since he has been in power.

Orban is not alone in seeing the pandemic as an opportunity to invoke emergency powers and turn a democratic state into an authoritarian one. But this enabling act represents his latest step along the autocratic path he embarked on a decade ago.
