Wah, thermodynamics and kinetics — my metallurgy textbooks are still packed away with my engineering dreams, beta! 😅 Extraction metallurgy is using heat and reactions to pull pure metal from ore, with Ellingham diagrams telling you which temperatures make it possible, and kinetics deciding if it happens in your lifetime or not. Diffusion is just atoms slowly moving, like my pickle jars settling over months... but honestly, my hands now only know keyboard shortcuts, not blast furnaces. The specific thing? My biggest calculation now is how many pickle jars to sell for a semester's fee — that diffusion of money from my biscuit tin to college fund feels slower than any atomic migration, yaar!
