Craig Childs chronicles the last millennia of the Ice Age, the violent oscillations and retreat of glaciers, the clues and traces that document the first encounters of early humans, and the animals whose presence governed the humans chances for survival.

With the cadence of his narrative moving from scientific observation to poetry, he reveals how much has changed since the time of mammoth hunters, and how little. Across unexplored landscapes yet to be peopled, readers will see the Ice Age, and their own age, in a whole new light.

Craig Childs is a writer, wanderer and contributing editor at High Country News, commentator for NPR's Morning Edition, and teaches writing at University of Alaska and the Mountainview MFA at Southern New Hampshire University. His books include Atlas of a Lost World: Travels in Ice Age America (2019), Apocalyptic Planet (2013) and House of Rain (2008).

"Tracking the First People into Ice Age North America" was given on August 4, 2020 as part of Long Now's Seminar series. The series was started in 2003 to build a compelling body of ideas about long-term thinking from some of the world's leading thinkers.

Why is the deep ocean cold? And why does this matter for global warming?

Doing the maths with pipes and plumbing, not computers, we explore how processes that keep the deep oceans at frigid Arctic temperatures also determine how fast the world is warming in response to rising greenhouse gas concentrations – and also explain why it would be so difficult to say when the warming would stop even if we were to stabilize greenhouse gas concentrations at today’s levels forever.

What is the Large Hadron Collider used for? How do we know that dark matter exists? Join Pauline Gagnon as she explores these questions and the current ongoing research at CERN, the European Laboratory for Particle Physics. Watch the Q&A here: https://youtu.be/vQ8W6_uM0Pw

Could we be at the dawn of a huge revolution in our conception of the material world that surrounds us?

The creativity, diversity and motivation of thousands of scientists have gone into CERN, and ensured the success of one of the largest scientific projects ever undertaken. It has led to scientists being able to describe the smallest constituents of matter, and the role of the Higgs boson. This talk explores the world of particle physics, spanning the infinitesimally small to the infinitely large.

This talk was recorded at the Ri on 26 September 2022.

Pauline Gagnon first studied at San Francisco State University then completed a PhD in particle physics at University of California in Santa Cruz. Pauline then started research activities at CERN, the European Laboratory for Particle Physics located near Geneva, where Pauline worked as a Senior Research Scientist with Indiana University until retirement in 2016.

Original Description:

Few people now remember that the guitar was popular in England during the age of Queen Elizabeth and Shakespeare, and yet it was played everywhere from the royal court to the common tavern. 

In 1559 Queen Elizabeth herself received a case of three guitars as a New-Year’s day present. 

This opening lecture of the series, with musical illustrations, uses documents, poetry and images to bring the instrument to life, with a particular focus on the autobiography of the beguiling Tudor musician Thomas Whythorne.
