Wealth on Instagram: "This small wooden “dollhouse” explains why fires become deadly faster than people expect. 🚒💨 Firefighters use these training models to visualize airflow, oxygen intake, and pressure buildup during a real house fire. When a door or window opens, fresh oxygen rushes in, feeding the flames and accelerating heat, smoke, and fire spread within seconds. This demonstration shows why closing doors behind you during a fire can slow flame growth, reduce toxic smoke movement, and bu

Code Intellectus on Instagram: "AI autonomously designed LEAP 71’s NEURON - 20kN aerospike engine, 3D-printed it in one copper piece, and it fired perfectly on the first test. Once the system learns, new design iterations take just 15 minutes. The insane part: burns at 3,000°C inside while using liquid oxygen at -183°C for cooling. So cold outside it creates frost while running full blast. Those green flames? Copper burning - a design quirk that taught the AI for next time. This isn’t AI helping
