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.

Black Lives Matter: Why "All Lives Matter" is a False Equivalence

The phrase “All Lives Matter”, used in response to the slogan “Black Lives Matter”, has been causing a lot of controversy. The slogan is sometimes used by “colour-blind” people, who do not see colour as a basis of any of their decisions, and when they hear “Black lives Matter”, they want to add white lives to the mix, not understanding that race causes significant differences in what people face with respect to discrimination. 

In one of the incidents, a man spray-painted ‘White Lives Matter’ on the statue of Arthur Ashe, an African American Tennis legend, who was the first black Wimbledon men’s singles champion. After the man left, some people spray-painted “Black Lives Matter” over the previous paint. The man returned in a while to wipe off that message, and when asked why he had painted “white lives matter” on the statue. According to the video, the man replied "Don't all lives matter? Why is it okay to spray paint on this statue 'black lives matter,' but not 'white lives matter'? What's the difference? They all matter. Everybody matters, right?"

However, John Hayward on Breitbart throws a different light on the use of the all lives matter slogan. It talks about several instances of how people and organizations have used the phrase, like how the local authorities in Frankton, Indiana tried to have it on the side of the police cars out of general goodwill, and did not realize that the phrase was offensive to the Black Lives Matter movement.

The phrase “All Life Matters” may have been used as a slogan for joining all hands together, and expressing the fundamental right to equality. However it is found to be misguided and offensive by many people because they feel that the phrase invalidates the specific difficulties faced by the black community. For explaining this, they draw a comparison: if there is one house burning, if the other houses call out that they want the water poured on them too, that’s just counterintuitive and ignoring the burning house. Another comparison is that at a dinner table, a child has half a portion and the other has a whole. When giving another half a portion to the child with less food, if the other child demands half a portion too, it is evident that the child with the full portion is ignoring the fact that the other one has only the half. 

The intention about the usage of the phrase “All Lives Matter” doesn’t matter; it still negatively affects the “Black Lives Matter” movement. Speaking of “All Lives Matter” in response to someone asserting that “Black Lives Matter” is walking over the struggles that black people specifically face and it is a false equivalence.
