Figuring Out with Raj Shamani

How A Nuclear War Ends The World In 72 Minutes | Annie Jacobsen | FO581 Raj Shamani

Annie Jacobsen - investigative journalist and bestselling author of Nuclear War: A Scenario, Area 51 and Biological War - walks Raj Shamani through how civilization could end in 72 minutes. She explains fission versus fusion ('a thermonuclear bomb is so powerful, it uses an atomic bomb inside of itself as the fuse'), the numbers (about 12,500 nuclear weapons on the planet, 1,700 American ones on ready-for-launch, some airborne 60 seconds after a presidential order), and sole presidential authority: one person can authorize nuclear war without asking Congress, the defense secretary or anyone. She takes us minute by minute through her scenario - the six-minute decision window, launch on warning, the black book, the doomsday plane, the universal unlock code, 44 interceptor missiles with a 40-55% success rate, why US missiles aimed at North Korea must overfly Russia, and how that misunderstanding ends the world. Then the second half: why biological war scares the Pentagon more - 3,600 BSL-3/4 labs worldwide, no inspections because the weapons are illegal, a Soviet defector's confession that the plan was to 'kill everyone in the West and leave the infrastructure intact,' and the classified Devolution Plan to reconstitute the government after everyone dies. FULL COVERAGE: the captions appear to cover the entire episode. All accounts and claims are the guest's own reporting, not independently verified. Sponsor: Porter (title sponsor).

Figuring Out with Raj Shamani

Why India Is Becoming Unliveable: Heat, Climate Change & AC Trap | Arunabha Ghosh | FO580 Raj Shamani

Arunabha Ghosh - founder-CEO of the Council on Energy, Environment and Water (CEEW) and one of India's leading voices on climate and energy - explains to Raj Shamani why 98 of the world's 100 hottest cities are now in India and what that costs. His institute's district-level research: 8 out of 10 Indians live where extreme flood, cyclone or drought risk has jumped; 75% of India's 734 districts are now extreme-weather hotspots; and 40% of districts are swapping trends - flood-prone turning drought-prone and back. The economics: roughly $180 billion in heat-stress losses by 2030 (more than the entire IT industry earns), 30-40 million man-days lost when outdoor labor stops from noon to 4 pm, and an 8x rise in cooling demand by 2040 - the AC trap, where the fix heats the city further. He covers the energy-security shock (90% of India's oil imports, much through the Strait of Hormuz, and a budget built on $65 oil meeting $115-120 reality), who actually emits (power first, then steel/cement/aluminium; cumulatively the US, then Europe, then China), geoengineering's promise and danger, what Medellin, Singapore, Paris and Beijing got right, and three concrete opportunities for young founders - recycling, the bioeconomy and next-generation energy hardware. (This episode is in Hindi; all notes are in English and translated quotes are marked.) FULL COVERAGE: the captions appear to cover the entire episode. All figures and claims are the guest's and his institute's research, not independently verified. Sponsor: none stated in the episode. Nothing here is financial or professional advice.

Astronaut Shubhanshu Shukla On Space, ISS, Zero Gravity & Human Body | FO536 Raj Shamani

Group Captain Shubhanshu Shukla - test pilot, fighter pilot and the first Indian to reach the International Space Station - explains rocket science to Raj Shamani like he is talking to a kid: why orbit is really a continuous free fall, what 0 to 28,500 km/h in eight and a half minutes does to a human body, and how a docking at 28,000 km/h is choreographed down to centimeters per second. He describes what microgravity does to blood, hearts, height, balance, taste and tears; life aboard the ISS (98% recycled water, floating sleep, shared Indian food from DFRL); the night flyover of India that left him with tears pooling in his eyes; and the full road there - a secretly filled 20-rupee NDA form, the academy that broke him down, 2,000 flying hours, a test-pilot course at 30, and a Gaganyaan selection process with 40 blood vials and a 7-day isolation exercise.
