Let's make this birthday one to remember.

77 years old (Born on February 28, 1948)

Happy Birthday, Steven Chu! May your day be cooler than atoms trapped by laser beams and brighter than the Nobel Prize medal you earned back in '97. Your groundbreaking work has illuminated physics (literally!)—and let's face it, anyone who can chill out atoms deserves a birthday filled with laughter.

From leading as U.S. Secretary of Energy to inspiring countless scientists worldwide, you've shown us that brilliance pairs perfectly with humor and humility. Here's hoping this year brings even more success—and perhaps fewer atomic puns from friends like me!

Cheers to another orbit around the sun—you've certainly mastered energy efficiency!
