This Machine Ran for 250 Years: A Marvel of Mechanical Engineering

@lumathink on Instagram: "This rocket engine wasn’t sketched, tuned, or optimized by human hands — it was designed by artificial intelligence from the laws of physics upward. The engine shown is LEAP 71’s NEURON 20 kN aerospike rocket engine, featured by YouTuber Intezga. Instead of engineers drawing CAD models, LEAP 71 uses a computational AI system that encodes thermodynamics, fluid dynamics, combustion physics, material limits, and manufacturing rules. Once given a performance target, the sys

Starting calisthenics early isn’t about doing crazy skills — it’s about building a real foundation of strength that carries over into everything. When you master your own bodyweight, you develop control, balance, mobility, and joint health that machines and weights alone don’t give you. Push-ups, pull-ups, dips, and squats teach your body how to move as one unit, not just isolate muscles. That foundation makes you stronger long-term, helps prevent injuries, and sets you up to progress faster whe
