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.

How the failure of political leadership resulted in the explosion of pandemic in Brazil

With over 1.2 million active cases and over 51 thousand deaths as on 30th June 2020, Brazil is one of the worst coronavirus affected countries. Latin America became the epicentre of the coronavirus pandemic in the latter half of May, largely due to Brazil’s incompetency in dealing with the pandemic. Due to the underreporting and low testing rates, the actual number of active cases and deaths are unknown.

The Brazilian Ministry started making changes to the number of cases reported, making it even harder to control the situation the pandemic has caused. The country’s response has been widely criticized in Brazil and outside. The President of Brazil, Jair Bolsonaro, dismissed the threat of the virus and the pandemic. OnMarch 26, 2020, he said that Brazilians are immune to the virus and even if they are drunk in a sewer they “don’t catch a thing.” He defied the guidelines set by his own health ministry and visited a busy commercial district in Brasilia, the capital of Brazil, where he told all the elderly Brazilians to get back to work. He also went on TV many times and called it little flu and accused the media of hysteria. Even as the coronavirus crisis has worsened recently, some major cities have eased their preventive measures, like Sao Paulo opening up shopping malls in Mid-June and beaches getting crowded again. With all of this happening, hospitals are close to running out of intensive care beds.

In early March, Brazil declared a public health emergency, a few days after the World Health Organization. The Ministry of Health in Brazil urged the officials to cancel all the public events and reinforce the measures of social distancing as prescribed by the World Health Organization. Some experts thought that Brazil could handle the pandemic based on its records during past public health emergencies. Brazil’s health care system is underfunded, but it does not fail to provide robust coverage across the country. The efforts of the state government went awry when the President called the virus a “cold” and provided anti-malaria tablets as a solution to the virus. President Bolsonaro’s clash with the governors and officials led to two health ministers leaving- one was fired and the other one quit. This left the military general, with no public health training, in charge of the virus. The clash amongst the government left the citizens of Brazil uncertain about the importance of following the preventive measures kept in place to prevent the spread of the virus. This led to the defying of the measures, which in turn led to the pandemic’s rate being one of the highest in the world.

The Ministry of Health has not presented a comprehensive plan to beat the virus yet. One of the main initiatives by the Ministry of Health is to boost the production of hydroxychloroquine and has encouraged the doctors in the public healthcare system to prescribe the same. The country has struggled to import lifesaving instruments, like coronavirus tests and ventilators. The lack of tests, in turn, has made it difficult to track the spread of the virus. This might result in the undercount of cases of the virus in the country.  Between Jan. 1 and June 6, 23,171 people who were not diagnosed with the coronavirus died from acute respiratory infections, according to data released by Fiocruz, one of Brazil’s state-run health research institutes. Experts believe most of them died from coronavirus.

At a time when Brazil needs to be putting all its efforts into fighting the virus, the president has been wrapped up in his own political battles. The Supreme Court is investigating allegations of disinformation and intimidation by the President’s supporters. Investigations also state that he has interfered in federal police investigations to protect his family. Due to this, the tensions between President Bolsonaro and the judiciary are high.

During the past few months, politics have become bigger than the pandemic. Even though the health crisis is extremely important, the magnitude of the political scandals has had a huge impact on how the country reacts to the pandemic. There is anger over how President Bolsonaro is handling the crisis and at the same time, there is a fear as to where the country is headed after the pandemic passes.
