Let's make this birthday one to remember.

81 years old (Born on June 13, 1943)

Happy Birthday, Harry Collins! Hope your day is absolutely gravitational—though knowing you, gravity waves might still remain suspiciously elusive despite the celebrations. We're convinced you've spent more quality time with invisible phenomena than most of us have spent binge-watching TV.

Yet somehow, amid exploring gravitational wave physics and shining witty philosophical insights since publishing *The Golem: What Everyone Should Know About Science*, you’ve made sociology not only understandable but entertaining too. May this birthday bring as much excitement—and fewer theoretical puzzles—as detecting cosmic ripples in spacetime. Enjoy blowing out those candles faster than Einstein revised his equations!

Cheers to many timeless adventures ahead!
