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.

Yemen's Multilayered War: Al Qaeda in Arab Peninsula

This is the 4th part of a short explainer article series on the current crisis in Yemen. To read the earlier parts of the series click on the following links.

The unification of Yemen in 1990 was a direct result of the military defeat of South Yemen at the hand of North Yemen forces. This military defeat and coerced unification implied that Unified Yemen could not achieve real cohesion, preventing the functioning of the nation as a democratic unit.

Meanwhile, newer elements were added to the dangerous mix of sub-nationalism, intra religious division, and tribal loyalty in Yemen. These were the Yemeni veterans of Soviet-Afghan war who fought with the Afghan mujahideen against the Soviet army backing the Afghan government.

These were hardline Wahabi and Salafi fighters, following an idealogy that mandated a strict interpretation of Islam. The fighters returned to Yemen in the early 1990s, after the withdrawal of Soviet forces from Afghanistan. The local Yemeni, both the Zaidi Shias or Maliki Sunni have traditionally followed a more liberal version of Islamic and social practices. Unlike the local Sunnis who were living in peaceful coexistence with the Zaidis Shia, these hardliners were antagonistic to the Shias.

Their arrival was followed by a forceful realignment of the local residents’ religious practices, mandating the local population to strict interpretations and social practices. Osama bin Laden, who had family roots in Yemen, was a conveniently placed ideological mentor. This led to a pushback from both the government forces as well as Shia groups, especially the Houthi-led Ansar Allah movement. In time, these former mujahideen, who were battle hardened and well versed in guerilla warfare, allied themselves with Al-Qaeda to start a low level insurgency in Yemen.

The Gulf war and subsequent stationing of American forces in Saudi Arabia and other gulf countries provided another impetus for the growth of Al Qaeda in Yemen. Consequently, they demanded that coalition forces leave Arabian land, failing which would result in more terror attacks.

Al-Qaeda affiliated groups attacked many installations associated with the US-led coalition forces in Yemen and nearby countries. The most successful of those was the famous bombing of USS Cole in Aden, in 2000. It was followed by a series of attacks leading up to  9/11.

Al-Qaeda in the Arab Peninsula (AQAP) is also known as the Ansar al-Sharia in Yemen is fighting to set up an emirate amidst the lack of leadership post the Houthi rebellion. It was this outfit that claimed responsibility for the attack on the French satirical magazine, Charlie Hebdo, in 2015 and is now considered the most dangerous al-Qaeda outfit by the US.

The CNN reported that “AQAP set out its objectives in a May 2010 statement as the "expulsion of Jews and crusaders" from the Arabian Peninsula, the re-establishment of the Islamic caliphate, the introduction of Sharia, or Islamic law, and the liberation of Muslim lands.”

The full list of attacks and places captured by terrorist insurgents in chronological order can be accessed here.

One of the outcomes of continual terrorist attacks has been a reduction in Hadi’s popularity. He is also seen as weak for not being able to stop al-Qaeda from terrorising Southern Yemen, as well as for not being able to alleviate them from their feeling of marginalization ever since the unification.
