Why Lithium-Ion Batteries Catch Fire: Thermal Runaway
The physics of lithium-ion thermal runaway explained — what triggers it, the chain reaction inside the cell, and how engineers actually prevent battery fires.
How Flow Batteries Actually Work: A Deep Explainer (2026)
How flow batteries actually work — vanadium, iron, and zinc-bromine chemistries, scaling math, grid economics, and where they beat lithium.
How Atomic Clocks Actually Work: From Quantum Resonance to GPS
How atomic clocks actually work — cesium hyperfine transitions, optical lattice clocks, what makes them so accurate, and why GPS and the internet depend on them.
How GPS Actually Works: Trilateration, Atomic Clocks, and Relativity
How GPS actually works: trilateration from satellite ranging, atomic clocks, the 38 microsecond relativity correction, ionospheric error, and how your phone gets a sub-5-metre fix.
