Here’s my favorite piece of trivia in the whole world: Dr. Marie Skłodowska-Curie showed up to her wedding ceremony wearing her lab gown.

It’s actually a pretty cool story: a scientist friend hooked her up with Pierre Curie. They awkwardly admitted to having read each other’s papers and flirted over beakers full of liquid uranium, and he proposed within the year. But Marie was only meant to be in France to get her degree, and reluctantly rejected him to return to Poland.

Womp womp.

Enter the University of Krakow, villain and unintentional cupid of this story, which denied Marie a faculty position because she was a woman (very classy, U of K). Dick move, I know, but it had the fortunate side effect of pushing Marie right back into Pierre’s loving, not-yet-radioactive arms. Those two beautiful nerds married in 1895, and Marie, who wasn’t exactly making bank at the time, bought herself a wedding dress that was comfortable enough to use in the lab every day. My girl was nothing if not pragmatic.

Of course, this story becomes significantly less cool if you fast forward ten years or so, to when Pierre got himself run over by a carriage and left Marie and their two daughters alone in the world. Zoom into 1906, and that’s where you’ll find the real moral of this tale: trusting people to stick around is a bad idea. One way or another they’ll end up gone. Maybe they’ll slip on the Rue Dauphine on a rainy morning and get their skull crushed by a horse-drawn cart. Maybe they’ll be kidnapped by aliens and vanish into the vastness of space. Or maybe they’ll have sex with your best friend six months before you’re due to get married, forcing you to call off the wedding and lose tons of cash in security deposits.

The sky’s the limit, really.
