Black Lives Matter Protest

Over 55 years have passed since the signing of civil right laws which were supposed to be the panacea for all the ills of raciest abuses faced by the Black-Americans. A lot has increased since for the Black Americans but much more is still to do. They still live in the fear of law enforcement officials who monitor their movement on the street and also in their homes. The blacks are killed  at the lightest alleged provocation by city police without any fear of serious repercussion. The Federals law enforcement agencies also have a history of racist behavior and brutality towards black Americans.

“Black Lives Matter” movement was started in 2013, after a white person named George Zimmerman was acquitted in the shooting death of African-American teen Trayvon Martin in February 2012. The movement got its name as the hashtag #BlackLivesMatter was widely used on social media to protest the acquittal of George Zimmerman.  This movement aims to highlight the injustices, brutality, oppression, gratuitous killings, systemic racism, ruthlessness, bad form, and unaccountably that American culture, particularly law implementation, harbours toward black individuals. Dissenters have pointed out the uncalled intensity of the police, military weaponry, and impulsive usage of the same. The problem of policing in America is more than just individual bad police officers, the culture protects wrongdoers and rewards blind loyalty and is impervious to change. American citizens have recognized these loopholes and will not tolerate these wrongdoings anymore

On 25th May 2020, a 46-year-old black man named George Floyd, died at the hand of a police officer after allegedly using a counterfeit $20 bill at the convenience store. The killing was extensively covered by the cross section of media across the USA and American public saw the horror of the painful death of an unarmed black person by the police. A national-wide protest erupted as millions of people, including whites came out in the streets,  demanding justice for George Floyd. Slogans such as “I can’t breathe”, “All lives will not matter unless black lives don’t”, “Stop police brutality” were raised on the streets across the cities of America. The “Black Lives Movement” which was hitherto mostly confined to a section of blacks youths, quickly expanded to include a wide section of American citizens. 

In his death George Floyd became the symbol of police brutality against the black community in the USA and brought the “Black Lives Matter” from the fringe to the center of American social and political discourse.

Physics and Technological Revolutions

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.
