1 Nov 2026Who Invented Alternating Current? The Dated RecordNo single person did. AC power was built in pieces between 1831 and 1891: generator, transformer, motor and line. The dates, checked.31 Oct 2026Did James Watt Invent the Steam Engine? The Dates, Checked Against the PatentsNo. Newcomen's engine ran in 1712. Watt's 1769 patent made it burn about a third of the coal. Every date, checked against the records.27 Oct 2026An H100 operation costs about 100 million Landauer limitsPhysics sets a floor for erasing one bit. At peak, an H100 spends about 100 million times that energy per operation: a scale, not a like-for-like test.17 Oct 2026What did Albert Einstein invent? His patents, checked against the recordsEinstein patented a fridge, a pump, a camera and a sound device with partners. Here is each one, checked against the patent records.13 Oct 2026Why data in optical fibre is 32% slower than lightData in fibre is often said to move at the speed of light. In standard fibre it moves at 204,107 km/s, 68.1% of it, because the glass slows the pulse.20 Sep 2026Moon Illusion: The Horizon Moon Is Farther and SmallerThe moon illusion makes a rising Moon look enormous. Measured, that Moon is about 1.66% farther away than the one overhead, and smaller.19 Sep 2026Franz Reichelt’s Eiffel Tower Jump: The Parachute Was Big EnoughFranz Reichelt's Eiffel Tower jump killed him in 3.4 seconds. His parachute suit was close to the right size. The way it opened never could be.18 Sep 2026Tsar Bomba Yield: The 100-Megaton Bomb Nobody BuiltThe Tsar Bomba yield everyone quotes was never detonated. Swapping lead for uranium halved the bomb and cut its fission output by 97%.13 Sep 2026Kola Superdeep Borehole: The Rock Beat the DrillThe Kola Superdeep Borehole stalled before the money ran out: at 180°C the granite went ductile and sealed the hole around the drill.12 Sep 2026Vela Incident: Why a Perfect Detector Still Divides ScientistsThe Vela Incident's bhangmeter was 41-for-41 on real nukes before 1979's double flash. Its optics, more than the spies, keep the case disputed.11 Sep 2026Challenger O-Ring Temperature: The 53°F Line NASA CrossedChallenger's coldest prior flight had its O-rings at 53°F. On launch day the failed joint was estimated at 28°F, about 25 degrees colder.10 Sep 2026Thomas Midgley’s Leaded Gasoline Choice Wasn’t About ChemistryThomas Midgley's leaded gasoline beat ethanol because it could be patented. Better combustion chemistry had little to do with it.30 Jun 2026CRISPR Makes History: One Injection Ends Hereditary AngioedemaIn vivo CRISPR gene editing has achieved its first Phase 3 victory: a single injection of lonvo-z cut hereditary angioedema attacks by 87%, with 62% of patients remaining entirely attack-free.30 May 2026From CERN to the Edge Data Centers. My Long JourneyFrom particle collisions to edge data centres. The infrastructure that powers science and the infrastructure that powers the internet have more in common than you think.8 Feb 2025Midong Solar Park: A Game Changer for Global Energy ProductionMidong Solar Park is one of the largest single solar installations feeding China's grid -- the scale, the technology, and what it signals for the energy market.8 Jan 2025SpaceX Starship: The Catalyst for a New Space EconomyThe Price Revolution of Space X Starship: Discover how $67 per Kilogram Redefines Space Cargo Costs 2 Jan 2025Are Electric Cars Dangerous? The Truth About Tesla FiresAre electric cars fire-prone? Check the reality behind the rumors and discover the truth about Tesla Fires and explosions 1 Jan 2025Can Hot Water Really Freeze Faster Than Cold? The Mpemba Effect ExplainedThe Mpemba effect refers to the counterintuitive observation that hot water may freeze faster than cold water under some conditions. Check if this is true.29 Dec 2024How Google Maps Knows the Best Routes and Predicts TrafficGoogle Maps predicts traffic from live and historical speed data reported by other users' phones, then reroutes you before congestion actually forms.24 Dec 2024Top 10 Innovative Megaprojects Shaping the Future of Our WorldDiscover the world biggest megaprojects, from $600B railways to $100B futuristic cities, showcasing innovation, sustainability, and global transformation.
