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 in Iran: Fighting pandemic while facing US sanctions

After backing out of the nuclear deal with Iran in 2018, the United States had toughened the sanctions on petrochemical trade and other vital sectors of Iranian economy. The Iranian government is claiming that those sanctions are heavily affecting their ability to act against COVID-19.

These sanctions forced the Iranian government to significantly change infocus from curbing the spread of infections to stabilizing the economy.  There have been some restrictions but no lockdown imposed on the movement of people as the lockdown would further weaken the economy. Also, a lot of pharmaceutical companies aren’t willing to trade with Iran because of the fear of getting caught up in secondary sanctions, even though the US governments deny any restriction of the same. 

All of this has led to a global outcry against the sanctions. The United Kingdom is pushing the US to ease the sanctions because they believe that the hospitals in Iran are badly overstretched. The UK tried to provide direct support to the country via WHO, but Iran refused any help that didn't come with the lifting of the sanctions. The United Nations High Commissioner for Human rights, Michelle Bachelet, has urged the global community to rethink the existing sanctions on countries like Iran in the light of the current pandemic. The United States also offered humanitarian assistance to the state but was rejected by the Supreme Leader Khamanei, who declared the US as being charlatans and liars, and said that a wise man should not accept medicines from a country alleged of creating the virus. Russia, China and some other medical and rights groups have been urging the Trump administration to lift the sanctions. Over 21,000 lawyers and legal experts in Iran have signed a statement declaring that the US sanctions on Iran are anti-human. On the 26th of March, the US imposed even more sanctions, on more than 17 entities. The sanctions were announced a day after the family of a retired FBI agent claimed that the agent had died while in custody in Iran; two days after Ms. Bachelet made her statement on rethinking sanctions.

The crisis has touched most corners of the country, but it is most severely impacting the poor and working class. While it is older men who are dying in the highest numbers, the economic impact especially hurts women, who are most liable to lose work, and shoulder increased duties, looking after sick relatives and children staying home from school. Iranians’ purchasing power has plummeted in the past two years, as the mismanaged economy shuddered through Donald Trump’s withdrawal from the nuclear deal and the re-imposition of US sanctions. As Nahid, a women’s rights activist put it: “When people met this virus, their nutrition was already poorer, their immune systems were weakened, and many were already unable to afford health care.” Charities and private sector groups are joining together to raise funds for importing equipment and other medical supplies from China to set up facilities of COVID-19. However due to the sanctions it is becoming difficult to move money from Iran to any other country.

Arshi Tirkey, a Junior Fellow with Observer Research Foundation has put quite aptly: “It is true that political instability, corruption and economic mismanagement in Tehran have aggravated the issue; and likewise, this calls for governance reforms and financial transparency initiatives in Iran. But this is not the sole reason for the scarcity of medical equipment and the condition of health infrastructure in the country today. Sanctions remain a central impediment to improving Iran’s capacity to respond to the pandemic.”
