Dmitri Mendeleev spent years organizing elements by atomic weight and properties, creating a system to predict undiscovered elements. His grand vision? Sparing future generations from rote memorization. Fast forward 150 years and chemistry students everywhere are frantically reciting "Hydrogen, Helium, Lithium..." the night before exams. Somewhere in the afterlife, Mendeleev is giving that exact disappointed look. The ultimate scientific betrayal - creating a tool to avoid memorization that became the very thing students are forced to memorize.
