Journalism in an Age of Misinformation and Centralization

Dan Gillmor

October 17, 02017

Long Now members can watch this talk free via livestream on our member site

As lying dominates politics and highly centralized entities increasingly control our media: is there any hope for honest news?

The Secret Life of Lightning: The Science of Giant Tesla Coils

Greg Leyh

September 26, 02017

Nikola Tesla’s wireless electrical system is more than a high voltage spectacle. Experiments with Tesla coils could help explain important questions about how lightning works. Bay Area citizen scientist Greg Leyh has built the largest
 Tesla coils in the world in his quest to better understand the physics of lightning.

Leyh's current project is completing a 40-foot tall coil which has been in the works for 5 years; and that's a step toward eventually building a pair of coils at 3 times that height. Invented by Nikola Tesla in the 01890’s, the Tesla coil produces high-voltage, low-current, high frequency alternating-current electricity with vivid electrical streamers that extend from the top of the coil.

Climate Change and the Future of Cities

Eric Klinenberg

March 7, 02017

What qualities help assure that
 a community can survive the threat of disaster?

At the same time the resources of cities offer tremendous potential for preparation and innovation.

As a sociologist, Klinenberg brings insights on how neighborhood dynamics (what he calls "social infrastructure") can help individuals & communities prepare for extreme weather including flooding and heat waves. He discusses how cities can be wiser and think more long-term by planning traditional infrastructure projects which also enable such social infrastructure in their design.

Breaking the Close: Burglary and the Limits of Architecture

Geoff Manaugh

February 14, 02017

Burglary reveals unexpected ways of moving through—and misusing—the built environment.

Seen through the lens of breaking and entering, walls become doors, sewers merely underground streets.

At the core of A Burglar’s Guide to the City is an unexpected and thrilling insight: how any building transforms when seen through the eyes of someone hoping to break into it.

Encompassing nearly 2,000 years of heists and break-ins, the book draws on the expertise of reformed bank robbers, FBI Special Agents, private security consultants, the L.A.P.D. Air Support Division, and architects past and present.

Pace Layers Thinking

Stewart Brand

Paul Saffo

January 27, 02015


Stewart Brand and Paul Saffo will discuss the Pace Layers framework for how a healthy society functions, which Stewart introduced in his book The Clock of Long Now (01999). More than fifteen years after its debut, this concept continues to be influential and inspiring. From January 02015.

The Pace Layers idea is illustrated by a simple diagram showing six layers which function simultaneously at different speeds within society. They range from Nature (the slowest) to Fashion (the fastest, shown at the top). As the layers progress, Stewart proposed, their differing speeds help make a society more adaptable. Cultures can be robust and healthy precisely because these layers come into conflict. Each level should be allowed to operate at its own pace, safely sustained by the slower levels below and kept invigorated by livelier levels above.

Though originally conceived as a tool for thinking about society, Pace Layers has had broad influence as experts in other disciplines have applied its framework to their areas including consulting and systems thinking. Jeff Veen of True Ventures (formerly Adobe, Adaptive Path, and Wired) recently said that Pace Layers provides a vocabulary to think about the stacked layers of contemporary design. Phil Libin, CEO of Evernote, has called the Pace Layers chapter in The Clock of the Long Now “the most profound thing I've ever read.”

Today in a networked world where everything seems to be about speed, awareness of the slower layers and perspective on how all layers interact can give insight into what the future may hold.

Philip K. Dick's Philosophical Machines

Erik Davis

November 18, 02014

Author Erik Davis is best known for his book Techgnosis: Myth, Magic, and Mysticism in the Age of Information. But he has been writing about Philip K.

Davis took time out from his dissertation on the "High Weirdness" figures of the early 01970s (which includes PKD) to give us a guided tour of the strangely inspired technologies that were born in Dick's fiction. And what's weirdest is how much they resonate with the tech we use today.

Philip K. Dick is widely acknowledged as one of the most important and prophetic science fiction writers of the twentieth century. His career and work is also deeply connected to the San Francisco Bay Area; he produced such landmark works of science fiction The Man In The High Castle, Time Out Of Joint, and Ubik while living in the area.

Futurist and Long Now board member Peter Schwartz shared his expertise and explain some of the tools of the futurist’s trade. First he discussed how futurist thinks about a subject, in this case the Future of the Internet. Then everyone attending broke out into small group discussions about that topic, applying scenario planning techniques to propose ways the Internet may change over years and decades to come. Finally the groups presented their work to Peter and the reassembled audience, and we wrote up the results on The Interval's chalkboard.
