Happy Birthday, William Unruh! May your celebrations accelerate faster than an observer experiencing quantum vacuums—after all, it's not only about aging gracefully but also observing it from the right state in space-time. Thanks to you, we're still puzzling over whether our coffee breaks change based on who's actually watching!Your groundbreaking work—the legendary 1976 revelation of the fascinating "Unruh effect" and distinguished career at UBC—continue inspiring physicists everywhere (and occasionally confusing them). Here's wishing someone who knows time is relative another timeless year ahead filled with academic achievements—and observers suitably impressed by every move you make!
