Carbon capture has existed commercially for over 50 years, yet it removes just 0.13% of global emissions. The gap between ambition and deployment reveals structural barriers in economics, engineering, and learning curves that subsidies alone cannot solve.
Evergreen Physics & Engineering Science & MedicineWhen small forces match a structure’s natural frequency, energy accumulates instead of dissipating. This is how soldiers marching in step collapsed a bridge, 40 mph winds destroyed a massive suspension span, and earthquakes selectively flattened mid-rise buildings while sparing their neighbors.
Evergreen Physics & Engineering Science & MedicineThe Apollo program proved we could reach the Moon, but building a permanent lunar base requires solving entirely different problems: million-dollar-per-kilogram transportation costs, lethal radiation exposure, and dust that cuts through spacesuits like glass.
Evergreen Physics & EngineeringBy 2030, the world will generate 5 million tons of spent lithium batteries annually, yet current recycling systems recover only a fraction of critical minerals. With 80% of lithium lost and China controlling 89% of refining capacity, the energy transition faces a supply crisis.
Evergreen Physics & Engineering Science & MedicineLow Earth orbit is filling with over 1.2 million collision-capable fragments, and the math says we may already be past the tipping point. The Kessler Syndrome is no longer a thought experiment; it is an engineering crisis measured in days, not decades.
Evergreen Physics & EngineeringThe “equal transit time” theory taught in most textbooks is demonstrably false. Wind tunnel experiments, NASA analysis, and a century of aerodynamic research reveal what actually keeps 412,000-kilogram aircraft airborne.
Evergreen Physics & EngineeringThe world burns over 100 million barrels of oil every day. Each barrel took millions of years to form. Here is the geological story of fossil fuel formation, from dead plankton to the kerogen cooking in Earth’s crust.
Evergreen Physics & EngineeringArtemis 2 is not a victory lap. It is a 10-day stress test of every system that must work before NASA sends astronauts to the lunar surface, from life support never tested with crew to a heat shield that cracked on its first flight.
Evergreen Physics & EngineeringSoftware bugs cost the U.S. economy over $2 trillion annually, and mathematics proves we can never eliminate them entirely. Three theorems from the 20th century explain why perfect software verification impossibility is a law of nature, not an engineering shortcoming.
Evergreen Physics & EngineeringA single uranium fuel pellet, smaller than a sugar cube, holds as much energy as a tonne of coal. Here is how nuclear reactors generate electricity by splitting atoms, boiling water, and sending power to the grid.
Evergreen Physics & EngineeringHumanoid robots have crashed below $16,000, and factories from BMW to BYD are already deploying them. The economics are brutal, the subsidies are enormous, and the production ramps are unlike anything the robotics industry has seen. Here is what is actually happening.
Evergreen Physics & EngineeringModern megafires don’t just burn through landscapes. They generate thunderstorms, spawn tornadoes, and inject smoke into the stratosphere with the force of a volcanic eruption. Here’s the fluid dynamics that makes it happen.
