Cation Memes

Ever had that mind-blowing moment in chemistry class? The Greek root "kata" (meaning "down" or "downward") connects these seemingly unrelated terms! Cathodes are where electrons flow down, cations are positively charged ions that move down toward the cathode, and catheters... well, they also involve a downward path! The skeleton dude is just as excited about etymology as he is about electrolysis experiments. Next time you're inserting a catheter or balancing redox equations, remember you're participating in a millennia-old linguistic tradition!
