Beautiful weekend outdoors. I love our national parks. I can't imagine climbing this though.

16 years ago today was one of the most important days of my life. Happy dating anniversary ❤️🎉🥂

Priscilla and I helped found the Breakthrough Prize to celebrate top scientific achievements in physics, math and life sciences. Tonight we presented the Fundamental Physics award to the Event Horizon Telescope team for the first image of a supermassive black hole. Congrats to all of this year's Breakthrough laureates!

Happy Halloween from our garden! 🎃 (I'm a drop of water. That's what happens when your three year old picks the theme.)

Stopped by to see Mosseri and a few publishers and creators talking about the future of media.
