A black and white photo of mathematician John Conway watching a cellular automaton game that he invented, play out on a circular screen.

John Conway was famous for coming up with recreational math problems that turned out to be challenging and deep. Mathematicians have now proved the existence of, and built, one of the strange shapes that intrigued him.

Inside arXiv—the Most Transformative Platform in All of Science Modern science wouldn’t exist without the online research repository known as arXiv. Three decades in, its creator still can’t let it go.

“Everybody in math and physics uses it.”

Nearly 35 years ago, Paul Ginsparg created arXiv, a digital repository for sharing research. It changed science for good.

Three decades in, Ginsparg reflects on its legacy—and its future.

Title: Just in time for Mother's Day: Classic literature with added Mums Panel 1: Moby Dick "Ahab! Moby! Enough of this nonsense. Apologise to each other and if you can't get along, stay apart." says Ahab's mother, standing in a little boat and looking sternly into Moby's eye, while her son sits chastened behing her. Panel 2: Casino Royale. "Vodka martini, shaken not stirred... And a sweet sherry for my mother." says James Bond. His mother calls over feom their table "Just a little one." Panel 3: The Lord of the Rings. "You can look for your ring after you tidy your room and walk the dog, Sauron." says Sauron's mother, holding out the dog lead to her son, who replies "Aw, mum!".

Happy Mother’s Day!
