Poor Lord Kelvin declared physics was basically finished in 1900, only to get absolutely steamrolled by the quantum and relativity revolution! The meme shows Kelvin as a lonely school bus while Einstein, Schrödinger, Bohr, and Planck come barreling down the tracks as unstoppable trains. Talk about a historical face-plant! Kelvin was measuring temperatures while these folks were casually rewriting the entire fabric of reality. Next time you're certain something is "complete," remember this epic scientific smackdown.
