Extracts from a Diary

Too Long; Didn’t Read (TL;DR): The Air Quality issue hasn’t been solved in Delhi-NCR/North India for decade+. Politicians would care if it were a major electoral issue or a major ‘interest groups’ issue. Residents don’t have enough exit options (alternate cities to move to).  Optimism : More people aware of the fact that there’s a problem. People willing to pay. Money & people => possibility of and motivation for technological, political, or social solution.  Prediction : Delhi will halve its current PM2.5 particulate matter in 8 years. But, it requires for the issue to become a voter priority. Long; Do Read: Introduction For the past few years, starting in mid-October, a few things happen without fail in significant parts of North India (and especially Delhi): Delhi skyline changes to the yellow-orangish tint, often seen in Hollywood/Netflix movies when they are depicting Mexico countless (and much-needed!) think pieces around: cause of the dangerously high AQI (at tim...

The Man Who Saved The World Vasily Arkhipov. That’s a man often credited, without exaggeration, for saving the world. On 27th Oct 1962, at the peak of Cuban Missile Crisis and during the Cold War between US and USSR, the two nations came closest to a nuclear war, and were averted due to the actions of Arkhipov. Vasily Arkhipov was a senior officer in the Soviet nuclear submarines at the time. The year before, in July 1961, while he was onboard a Soviet (nuclear-powered and nuclear-equipped) submarine doing some tests near Greenland, it developed a major radiation leak. The radio communication broke down too, and the crew had to devise a solution at that time on their own. They did. At the cost of major radiation exposure to all 139 crew members, with 22 of them dying within 2 years. There’s definitely a thrilling movie, if not a Chernobyl like series, in there somewhere. On 27th Oct 1962, Arkhipov was in another nuclear submarine (B-59), hidden well below somewhere in the Caribbean. Me...

The nuclear age left radioactive traces in all modern steel. The LLM age is doing the same to digital content. Some analogies and lessons from that. Radioactive Signature on Steel From around 1945 onwards, in specialised niches and applications, there came up a need for specialised steel — steel that was made from before 1945. You see, after the nuclear tests and detonations, there exists a certain level of diffused background radiation in atmosphere. While these detonations happened in US and Japan, initially, followed by USSR and elsewhere, the radiation spread quickly and to somewhat uniform levels, throughout the world. The typical steel-making process uses atmospheric oxygen. And this background radiation in atmosphere leaks into the steel-making process. All steel made after 1945 has a certain level of radioactive traces (or its radioactive signature) slightly and measurably higher than for steel made before that cut-off. There are a set of highly sensitive, niche applications, w...

Last week of August, I was fortunate to have travelled to Vietnam. I say fortunate because I loved every bit of it, and hope to be able to travel there again. We visited Ho Chi Minh City (also called Saigon or HCMC), Da Nang, and Hanoi — the three major cities across South, Central, and North Vietnam respectively. Each of those had a different flavour across the many dimensions — food, culture, traffic, road infrastructure, markets, coffee, among other things. Our trip was for about 8 days, and we definitely felt that was too short to fully soak in the things the country had on offer. But, it’s better to leave with an incomplete appetite and a desire to return, than otherwise. It was an excellent trip in absolute sense and in terms of value for money. History While Vietnam has had a continuous history of about 3000 years, in the modern era, it’s been a theatre of the different world powers. Under French colonial rule until World War II, control shifted to Japan after France fell to Naz...
