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 COVID-19 helped Netanyahu beat Benny Gantz for Israeli prime ministership

In March 2020, when COVID-19 was causing the near collapse of health systems across the world, Israel had just voted third time in the parliamentary election for the third time in less than a year. This was so because no political party was able to muster the majority in Knesset (Israeli parliament) after earlier elections in April 2019 and Sept 2019. Benjamin Netanyahu has been acting Prime minister since the time when he went for the dissolution of Knesset December 2018 with a hope of securing an extended majority for his right wing coalition. However he failed to secure even the simple majority in three elections on April 19, Sept 19, and March 20. Then came the COVID-19 and he sensed an opportunity to make a comeback from the brink of political disaster to reclaim the prime ministership of Israel.

The COVID-19 pandemic tested the Israeli citizens just like the other countries and  Benjamin Netanyahu kept on telling that unless it is effectively controlled, there will be devastation not seen since the Middle Ages. He also stressed that even the First world countries such as the US and UK are at the brink of losing control. Many Israelis expressed admiration towards Netanyahu’s quick response to the pandemic which helped to contain the pandemic in earlier stages. They flattened their curve by shutting down public places such as parks, schools, educational institutions, and the hotspot areas. He followed two stage strategies — first, to locate and isolate the infected population and then to engage the healthy population in economic activities during the conditions of a semi-lockdown. These steps were taken to save the economy. His plan also carried a huge amount of tests in the hope that it could be established that some people were developing antibodies to resist the virus and could safely be “freed” from isolation. Although the steps being acknowledged, they still raised a lot of questions against Netanyahu. He was supposed to be facing charges for breach of trust and bribery in the month of March. The court shutdown ordered by Israeli Law minister delayed Netanyahu’s charges by two months. Israel also used the cell phone of citizens to monitor their movement to track the spread of pandemic for which he was criticised for breaching the citizen’s privacy. Yohanan Plesner, the president of the Israel Democracy Institute said that Israelis trust the Shin Bet to protect them and not to abuse that trust, and the cellphone monitoring may have serious long-term effects on that trust. Netanyahu, however, defended himself with usual combativeness by stating that the courts were under a temporary shutdown and he has received permission from the General Attorney for cellphone usage data which was valid for 14 days. He also said “If the Shin Bet is to

infringe on our basic privacy, they could have done it many years ago”.

After managing to convince the citizens that he had handled the COVID-19 situation effectively, he quickly approached the rival Benny Gantz with a proposal to form an “emergency unity government”. As part of the deal he offered to share the power with Gantz’s Blue and White party for three years during which Netanyahu was to be prime minister and Benny Gants Dy prime minister for the first 18 months and the role reversal afterwards. He kept on harping the disastrous consequences of the virus and mentioned “It could affect 60-80% of the population” and said “nobody knows” how devastating the virus would ultimately prove. 

It was not easy for Benny Gantz to accept the proposal to align with Netanyahu as his whole campaign was on the issue of never supporting Netanyahu. However Netanyahu, who is acknowledged by friends and foes alike as a shrewd politician willing to go to any extent in safeguarding his own interest, finally won the war of attrition. Benny Gantz accepted the deal offered by Netanyahu and agreed to let him continue to be the prime minister for the first 18 months of the alliance period. The COVID-19 calamity has effectively turned into an opportunity for Netanyahu to hold on to the power and continue to be the prime minister of Israel.
