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: The Failing Healthcare Infrastructure

This is the 6th and last part of a short explainer article series on the current crisis in Yemen. To read the earlier parts of the series click on the link.

The civil war in Yemen, more so after 2015 has taken a toll on the civic infrastructure of the already fragile and poor country. Among these, the healthcare infrastructure of the country was one of the worst affected.

Apart from the physical damage to the hospitals and clinics due to the aerial bombings by the Saudi Arabia led coalition, the naval blockades exacerbated the dire situation. In June 2015 itself, aid agencies warned of the humanitarian risks brought by the US and UK-backed Saudi blockades.

The humanitarian situation aggravated further as there was a consistent famine since 2016 and Yemen was dependent on foreign aid for feeding almost 80% of its population.  According to UNICEF reports, over 3.3 million children and pregnant or lactating women suffer from acute malnutrition.

In 2017, the World Food Programme estimated that an additional 3.2 million people would be pushed into hunger. If left untreated, 150,000 malnourished children could die within the coming months.

Save the Children, the international charity and aid agency, estimated that 85,000 children under the age of five have starved to death in between 2015 to 2018.

Major healthcare operatives are dying due to the active bombing and conflict in Yemen, including personnel from MSF and United Nations Office for Coordination of Humanitarian Affairs (OCHO).

The MSF (or Doctors Without Borders), who have been in Yemen since 2007, have reported that fears of stigmatization are causing people to stay away from hospitals, with misinformation and lack of medical services only compounding the healthcare issue during the pandemic.

As of 24th July, the country reports 1640 confirmed infections and 458 related deaths.  Al Jazeera reported that “Cemeteries in Aden are overflowing with graves, suggesting that the number of people killed by the new coronavirus is higher than the official count.” Yemen and its related aid agencies also suffer from lack of PPEs and adequate information about the pandemic.

As of April 2020, there are 800,000 internally displaced persons in just one province of Yemen Marib. The number of verified civilian deaths stands at 7,700.

The United Nations has been continually asking for donations, but has failed to collect as much as it requires. While it collected $4 billion last year, it has only received $700 million, halfway into 2020.

The UN urged for $2.4 billion this year to fight the humanitarian crises and the Coronavirus. As of 2nd June, 29 countries and the European Commission pledged a total of $1.35 billion to support humanitarian efforts in Yemen, just over half of the amount needed to sustain programs through the end of this year.

In April 2020, the Saudi deputy defence minister, Prince Khalid bin Salman, said Saudi Arabia “will contribute $500m to the UN humanitarian relief program for Yemen in 2020, and an additional $25m to help combat the pandemic. It is up to Houthis to put the health and safety of the Yemeni people above all else.”

There are 41 major UN programmes in Yemen, and it is estimated that more than 30 of them will close due to lack of funds. The UN stated, “Due to the COVID-19 suppression measures, all integrated outreach activities, which include the Expanded Programme on Immunization, Integrated Management of Childhood Illness, Maternal and Newborn Health,and nutrition activities, were suspended.”

Most of Yemen's 3,500 medical facilities have been damaged or destroyed in air strikes, and only half are thought to be fully functioning. Officials warn that monetary relief may not be enough to assist in the war against the pandemic alongside the Civil War. A solution to the war must be found soon, before the pandemic eviscerates more of the healthcare infrastructure.
