Oceanic C:N:P ratios do not follow the classic Redfield ratio stoichiometry—recognized for some time—but they follow large-scale patterns. Indian Ocean has higher C:N:P than Redfield, yet consistently lower than those in the Atlantic Ocean and Pacific: https://t.co/cVPJARqJYg
Scientists from the US & Europe had to fly to India to learn how to read the planet from him. He turned the Indian Rain into a global Data Stream for climate science. To his neighbors, he was likely just a man obsessed with collecting rainwater in buckets; to the globe, he was the Admin of Earth’s Timeline.
In the 1950s, scientists knew how to date very old things (billions of yrs) & very young things (C-14 for the last 50000 yrs). But there was a Blind Spot in the timeline: the last 100 to 1000 yrs, the era that defines our current climate crisis. Dr. Devendra Lal realized that when cosmic rays smash into the atmosphere, they create Silicon-32. This isotope falls with the rain & gets trapped in the layers of the ocean & ice.
Silicon-32 is incredibly rare. Detecting it is like looking for a single specific grain of sand in a desert. To find it, we needed massive data sets which in his world, meant 1000s of liters of water. While Western scientists tried to simulate these processes in sterile labs, Lal used the Direct Energy of the Indian climate.
During the heavy Monsoons, Lal & his team at TIFR did not just stay indoors. They set up massive collection systems. They were essentially using the entire Indian subcontinent as a capture card for cosmic data. He proved that the Monsoon was a Conveyor Belt that brought cosmic isotopes from the stratosphere down into the deep-sea sediments. He turned a Natural Disaster into a Precision Tool.
Because of Lal’s work, we could suddenly read how fast ocean currents move, the circulation logic of the planet. Before Lal, the deep ocean was a black box. His Silicon-32 method acted as a Timestamp.
By measuring the decay of the Silicon-32 he found in ocean sponges & sediments, he could tell exactly how many yrs ago that water was last at the surface.
When the US launched the GEOSECS (Geochemical Ocean Sections Study) project (the most ambitious ocean mapping in history), they depended on his protocols. The global admin of the project was a man who had perfected his craft in a Bombay lab.
Lal once spent weeks collecting giant ocean sponges because they were the Hard Disks that absorbed his isotopes. To the world, these were just sea-scrubbers; to Lal, they were archived data packets of the 18th century.
#UPSCResult2025 reveals 0.16% success rate. 958 successful out of 5,76,793. No1 is a doctor who wanted to become IAS, the day he joined as doctor, bcs he realised a babu rules over Doctor also. The second is a deputy collector who after graduation in 2018 as an NCC cadet in college, planned to join IPS - so 8 years tapasya. Third Akansh who came to me for mock interview, planned after school in 2018 to appear for UPSC.
This is the opportunity cost of UPSC exams. From IITians and doctors, to the very best in land, waste years after years to join services to become babus and cops. Precious man-hours lost by brilliant men who leave aside the world of AI, Quantum computing, space tech, ocean engineering, banking, medical, housing, cyber - to join as babus and cops. Why! because of safety and unbridled power. And also bcs our Netas wanting to rule the junta in 5 year stints, need these 2 only.
We are 90 years behind
World is building new LLM models, meanwhile In India CS graduate from IIT are busy clearing UPSC exams.
It's not his fault but the system that rewards administrative power more than creative and technical skills. No wonder we have to buy robot from China to show in AI summit.
IIT comp science will now end up as a cop or customs officer. The fault is not this kids. He is doing what’s best for him because the system and structure he functions in disincentivises creativity, entrepreneurship, innovation. And then we wonder why India is not innovating fast enough, why manufacturing is suffering, where are the tech giants building tech that world wants. As long as something as unproductive and useless as IAS will be the dream of our best and brightest, and as long as these services remain the most privileged without any contribution whatsoever, the dream of viksit Bharat will remain a dream. Worse, we will keep asking for transfer of tech because we don’t want to put the brains and money into developing our own tech. Our brains will be happy pushing files, seeking and lobbying for their next posting, ensuring they get jobs where memsahib has a car to her disposal for shopping and a flat in Lutyens delhi as per their entitlement.
Today, on National Science Day, we celebrate the spirit of research, innovation and scientific curiosity that drives our nation forward.
This day commemorates the groundbreaking discovery of the Raman Effect by Sir CV Raman. This discovery placed Indian research firmly on the global map.
We reaffirm our resolve to empower our youth, strengthen research ecosystems and harness science and technology for national development and global good.
🌊 Science for society takes center stage at #OSM2026 in Glasgow (22–27 Feb).
Early career researchers will spotlight critical findings on ocean deoxygenation, cryosphere governance, and marine carbon dynamics — advancing knowledge that strengthens climate resilience worldwide.
🎉 New paper published! 🎉
We show that the Arabian Sea OMZ laterally expanded during the LGM and contracted during the deglaciation, highlighting a strong climate control on past ocean deoxygenation. 🌊🧪
