My first encounter with physics came when I was eight years old, inspired by the story of a great scientist who left an unfinished manuscript on his desk. This sparked my fascination with the universe and the fundamental laws governing it, particularly the legacy of Einstein and his elusive theory of everything, which aims to encapsulate the workings of the cosmos in a single equation.
What you actually carry around is a tiny slab of black magic-an object so packed with impossibility that, if you understood even half of what it's doing right now, you'd either laugh out loud or quietly set it on fire.
