Let's make this birthday one to remember.

91 years old (Born on April 02, 1934)

Happy birthday, Paul! May your celebrations be as infinite as the sets you've explored and your happiness as unprovable (yet widely accepted) as the Continuum Hypothesis. Your groundbreaking work in set theory has left mathematicians scratching their heads—and secretly envying your genius—for decades.

Here's to another year of redefining mathematical boundaries and making us question everything we thought we knew about infinity. May you continue to find joy in life's paradoxes, laughter in logical contradictions, and cake slices that defy finite measurement.

Cheers to you, Paul—may this birthday be one for the history books (or at least a footnote)!
