Watch the Creative Sparks Fly
Two weeks ago global leaders in politics, academia, and business gathered at the World Economic Forum in Davos, Switzerland to share their vision for a better world. At the 2022 World Economic Forum, we brought together two brilliant minds from vastly different fields to share their own ideas—world-class cellist Yo-Yo Ma and CERN Director Fabiola Gianotti. In a conversation recorded for our series The Intersection, Ma and Gianotti shared their thoughts on the hybridity between music and science, the search for truth, and the nature of creativity itself.

Nautilus members get a front-row seat to their discussion—it’s cheaper than airfare to Davos!

P.S. The 19th-century mathematician and writer Lewis Carroll, author of the children’s novel Alice’s Adventures in Wonderland, was born yesterday, Jan. 27th, in 1832. Carroll was an avid “puzzler”—a maker and solver of logical games. It’s an analytical hobby that another sharp mind, the late Raymond Smullyan, later took up. The theoretical computer scientist once devised what came to be called the Hardest Logic Puzzle Ever. Can you solve it? I for one, dear reader, could not. Though, as I wrote, the solution turned out to be “one of the best lessons in logic and truth I have ever received.”
