77 years old (Born on July 20, 1947)
Happy Birthday, Gerd Binnig! Your groundbreaking work with the scanning tunneling microscope didn't just earn you a Nobel Prize in Physics—it also gave scientists everywhere an excuse to say they're "tunneling" without sounding like moles. Thanks for making atoms visible and giving physicists something cooler than lasers to brag about at parties.As an IBM Fellow since 1987, you've continued inspiring innovation and curiosity. May your birthday be filled with joy brighter than electrons under your microscope—and may all your cake slices be precisely measured down to the atomic level. Cheers to another year of exploring life's smallest wonders!
