The Conversations at The Interval
Interval events are lectures and discussions about topics including art, design, history, nature, technology, and time. They take place on Tuesday nights a couple times a month and feature artists, authors, entrepreneurs, scientists, and others who take a long-term perspective.
Below you'll find information about upcoming and previous talks. All events are recorded and will eventually be released. There is video and audio of a selection of our past talks on this site. We also have nearly 200 videos in our Seminar series which you can watch for free.

In August of 02018, Long Now founder Stewart Brand, renowned geneticist George Church, and a delegation of observers and scientists traveled to one of Earth's most remote places to witness the ongoing restoration of a part of Siberia back to its Pleistocene-era ecosystem. The team brought back DNA samples to evaluate for mammoth de-extinction, and lots of photos, video, and stories of a place where climate change and arctic deep time can be witnessed at once. At this event Long Now's Stewart Brand, Kevin Kelly, and Alexander Rose will be joined by filmmakers David Alvarado and Jason Sussberg to discuss the trip and the things they learned along the way.
Tickets typically go on sale to Long Now members two weeks in advance and then to the public. Most talks sell out quickly due to our small capacity. "Patron tickets" are usually available after other tickets sell out. They include a reserved seat and are partially tax deductible.
Talk begins at 7:30pm; we recommend arriving earlier for more seating options. The Interval reopens to the public by 8:30pm. (All times are in Pacific Time)
A live videostream of most talks is available. Each talk is free for Long Now members at http://longnow.org/live
