The Day Humans (Accidentally) Launched a Manhole Cover at 150,000 MPH 🚀 Need a quick break from the spreadsheets? Here is one of the most absurd, rousing tales from the history of physics to brighten your feed. In 1957, during a nuclear test known as Pascal-B, scientists were exploring whether they could contain a blast underground. As part of the experiment, they welded a 900-kilogram (2,000 lb) iron cap—essentially a massive manhole cover—over the top of a 500-foot deep borehole. When the device detonated, that borehole effectively became the world’s most powerful "nuclear potato cannon". The results were legendary: 💨 The Speed: Post-test calculations suggested the cap was propelled at six times the Earth's escape velocity—roughly 150,000 miles per hour. 📸 The Evidence: A high-speed camera filming at 1,000 frames per second caught the cap in exactly one frame before it disappeared forever. 🦇 The Verdict: Project scientist Robert Brownlee summed it up best: when last seen, it was "going like a bat!". The cap was never found. While some dream that it beat Sputnik into space, most scientists believe the "manhole cover" likely vaporized into a plume of plasma within the first second of its flight due to intense atmospheric friction. Next time you feel like your workday is moving too slow, just be glad your projects aren't disappearing at Mach 200! #History #Physics #Space #OperationPlumbbob #WorkBreak #FastestObject

New Post: Automated Multi‑Modal Evidence Integration for Neutrino‑Driven Wind Nucleosynthesis in Core‑Collapse Supernovae - **Automated Multi‑Modal Evidence Integration for Neutrino‑Driven Wind Nucleosynthesis in Core‑Collapse Supernovae** — ## Abstract Core‑collapse supernovae are the principal astrophysical laboratories for rapid neutron‑capture \(r‑process\) nucleosynthesis. Accurate prediction of the elemental yields emerging from neutrino‑driven winds requires coupling general‑relativistic hydrodynamics, detailed neutrino transport, and expansive nuclear reaction networks—an endeavor that is both computationally expensive and \[…\]

𝐓𝐡𝐞 𝐁𝐨𝐭𝐭𝐥𝐞𝐧𝐞𝐜𝐤 𝐈𝐬𝐧'𝐭 𝐓𝐞𝐜𝐡𝐧𝐨𝐥𝐨𝐠𝐲. 𝐈𝐭'𝐬 𝐒𝐭𝐚𝐧𝐝𝐚𝐫𝐝𝐬. Commercial radioisotope power systems are ready. The missions need them. But without industry-led consensus standards for testing and qualification, we're stuck in a cycle of one-off approvals and regulatory uncertainty. 𝐓𝐡𝐚𝐭 𝐜𝐡𝐚𝐧𝐠𝐞𝐬 𝐚𝐭 𝐍𝐄𝐓𝐒 2026. Join Pacific Northwest National Laboratory for a first-of-its-kind workshop on 𝐌𝐨𝐧𝐝𝐚𝐲, 𝐀𝐩𝐫𝐢𝐥 27𝐭𝐡, 2-5 pm to chart the path forward for commercial radioisotope heat and power systems. This isn't another panel discussion. It's a working session where space nuclear leaders will collaborate on a roadmap for industry-developed standards that drive innovation, ensure safety, and actually get new designs qualified for flight. 𝐖𝐡𝐚𝐭'𝐬 𝐨𝐧 𝐭𝐡𝐞 𝐭𝐚𝐛𝐥𝐞: • Current standards landscape and critical gaps • Industry's role in creating a successful safety framework • Building consensus on testing and qualification requirements • A clear path to commercial deployment If you're developing RPS technology, planning missions that need it, or working the regulatory side, this is where the framework gets built. PNNL brings deep technical, regulatory, and policy expertise. You bring the operational reality and commercial perspective. Together, we create the standards that unlock the market.

Really cool to see NORM, which is integrated on our ASBM-2 satellite is now providing valuable data on the space radiation environment along its three-apogee (TAP), 16-hour highly elliptical orbit (HEO).

You left out Nuclear pulse detonation... Thats how someone got phobos and deimos into orbit around Mars... Thats far more effective and proven way to do heavy lifting in space. Here is my evidence. Decide for yourself. The odds of these asteroids being natural astronomically low enough as to be non zero probabilities we can assume didnt happen. Someone used nuclear bombs to split Phobos and Deimos apart and used nuclear pulse detonation to place them into perfect orbit around Mars. Was it us? Maybe the monolith tower will tell us ...when we get there. https://lnkd.in/erZthunN

🔬 James Chadwick's Beryllium Radiation (Neutron Discovery) ✨ Listen, fellow explorer: the universe often whispers its secrets before it shouts them, and Chadwick’s neutron discovery began with a quiet clue. It wasn’t a towering formula that led the way, but a surprisingly deep penetration signal that refused to match any known gamma‑ray pattern, forcing a fresh look. ✓ ⚛️ 1. He detected unusually strong penetration in radiation measurements, attributing to gamma rays, trying to filter out background. ✓ 🔭 2. Detailed scattering experiments showed particles were neutral, massive, not photons. ✓ ⚛️ 3. Discovery of the neutron completed nuclear model, enabling fission and modern nuclear physics. 🟢 What subtle 'noise' in your data might actually be a hidden signal? #PhysicsHistory #NeutronDiscovery #ScientificObservation #DataInsights #ResearchMoments
