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.

US Sanctions versus Iran’s fight against COVID-19 pandemic

Iran is the hardest-hit country by the coronavirus pandemic in the middle east. The contagion was first detected on 19 February 2020 in the holy city of Qom, and thereafter spread quickly across the country. As of 18th June 2020, it had over 9000 coronavirus related fatalities. The virus attacked all the 31 provinces of the country not discriminating between the common man and the people at high places including the members of the Parliament, religious leaders and senior ministers. The crisis touched most parts of the country, but it most severely impacted working and the poor class. 

The Iranian government has been criticized for its response towards the pandemic. The health care policy, which has been politicized, has preferred denial and misinformation as a response to the crisis the pandemic brought with it. Questions have also been raised about the role of US sanctions in crippling Iran’s economy, public health facilities and public health facilities. All these factors, when combined, have disabled Tehran (the capital of Iran) from providing the best response to the pandemic. 

What do the sanction laws say?

According to the Office of Foreign Assets Control, the US has “consistently maintained broad exceptions and authorizations to support humanitarian transactions with Iran.” The first significant sanctions were imposed in 1995 by Bill Clinton, and in 2001 exemptions for medical goods and medicine first came into effect. These sanctions have periodically widened the scope of products for exemption, and by 2012, the exclusions included agricultural products and most foods. After the world powers, including the US, reached a deal with Iran on its nuclear programme in 2015, the sanctions were lowered against Iran. This approach was abandoned after Trump withdrew the US from the deal and sought to force Iran’s leaders to change their anti-US policy. .

The US sanctions are enforced through a wide array of instruments. Financial sanctions prohibit US banks from transacting with Iran, which limits Iran’s access to dollar-denominated transactions. Secondary sanctions measures also target non-US entities that have dealings with Iran, thus at a risk of facing prosecution in the US. These sanctions make transactions with Iran lengthy and complicated, and even impossible in some cases

There are some exemptions from sanctions for humanitarian assistance (sale of agricultural commodities, food, medicine and agricultural services). Despite these exemptions, sanctions have severely impaired Iran’s ability to be able to finance humanitarian imports. Given the volume of complexity and due diligence involved, most banks are reluctant to deal with Iran. This makes it difficult to find a way to pay for purchases difficult for Iran. Also many items require additional authorization because the US considers them as “dual-use” (the things might also be used for defence- for example, the sort of oxygen generators that are needed in life support machines used to treat coronavirus cases). Lastly, the sanctions on Iran’s oil exports led to a decline in revenue, further weakening Iran’s currency, which has left the country vulnerable and with fewer resources to pay for non-sanctioned items as well. 

All these put together have directly caused shortages of medical equipment and impacted Iran’s health sector negatively. This has also impacted the capability of Iranian healthcare sector to effectively manage the COVID-19 situation.
