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.

Expat Exodus In The Middle East

The COVID-19 pandemic has hit people and economies worldwide, sparking a global recession and financially destabilising millions of people. In the Middle East, dipping oil prices have only worsened the threat to the economy. Businesses are shutting down, and many are trying to survive by cutting the salaries or laying off of workers. Large segments of the workers in these countries are expatriates, and many have struggled to make ends meet as unemployment soared.

The development of the Gulf countries has always been intertwined with their large expat populations. These workers are often vital to the economy, not just as part of the workforce but also as consumers by enabling successful malls, restaurants and other forms of recreation and tourism. Countries like Saudi Arabia gain valuable non-oil revenue in the form of increased Value Added Taxes (VAT) and by imposing a monthly fee on migrants who want to sponsor family members.

Many of these workers are from developing Southeast Asian countries such as India and Pakistan, and contribute greatly to their home country’s economy in the form of remittances, i.e sending money back home. Those who are facing unemployment or salary cuts are eager to be repatriated, especially since in many Gulf countries visas, rent, and even phone lines are linked to jobs, and expats have little to no social safety nets to fall back on.

Panicked” Indians applying to go back home crashed the Dubai aviation ministry’s website for applications in the process. The consulate says it has received around 200,000 applications for repatriation of expats from as many as 12 countries.

For some, closing businesses are forcing them to go home. For others, the cost of education is the major concern. The Emirates group, Uber’s Middle Eastern counterpart Careem, and hotels are some of the few major employers considering laying off large portions of their staff or reducing salaries.

Dubai has been one of the hardest hit, as expats form an estimated 92% of the population. Dubai based movers estimate that they’re getting up to seven calls a day to ship belongings abroad. It is extremely hard to gain permanent resident status in countries such as the UAE, and the costs of living and education are quite high and often provided by employers, which has made leaving the only option left for many laid-off workers across all fields.

The UAE has tried to offset the damage by granting automatic extensions to expiring work permits, waiving of work permit fees and fines, and providing interest-free loans and repayment breaks.

Meanwhile, governments in Kuwait and Oman are trying to mould the exodus into an opportunity to boost local employment. On the other hand, the Saudi Arabian government has been criticised for not taking enough measures to protect the local workforce.

While the Gulf countries have been trying to decrease their dependence on oil wealth and foreign workforce, it is not something that can be accomplished soon, especially given the great dependence of the Gulf economies on both those factors.

There is still too unavoidable a gap between the current skill of local workers and the training needed to compete with foreign professionals, making it hard to simply employ domestic workers in place of foreign ones. The pandemic, however, might not leave much of a choice.
