Guess who’s 100 and still expanding the frontiers of our world! Fermium, atomic number 100, has been used in experiments to synthesize heavier elements, playing a crucial role in expanding our knowledge of the atomic nucleus. Like fermium, you’ve played a crucial role in our lives, teaching us, guiding us, and expanding our horizons. So here’s to denying the opposite of usefulness at any age—may you continue to lead, teach, and inspire. Much love on your incredibly special day!
