NEW YORK TIMES BESTSELLING AUTHOR

Jo Marchant UK

Global Conference Opening Keynote

Jo Marchant is an award-winning science journalist and author of popular books including Decoding the Heavens and The Human Cosmos. Her writing explores the nature of humanity and our universe, from the mind-body connection to the mysteries of past civilizations and the awesome power of the night sky. This talk will explore the cultural importance of the sky – telling a story of how the Sun, Moon and stars have inspired and guided humanity since Palaeolithic times – and trace how our relationship with the stars has changed as we’ve built a scientific understanding of our universe and become more reliant on technologies from central heating to GPS.

Jo will argue that alongside the elegant and powerful explanations of science, our physical, spiritual and ecological wellbeing depend on rediscovering a more personal connection with the cosmos in which we live.

Global Conference Opening

Tom is a retired Washington, D.C., lawyer who spent most of his career representing airlines and railroads in labor and employment matters, including extensive experience translating scientific experts for lay decision-makers. He is a graduate of Harvard College and the Harvard Law School.

His environmental activism included a decade fighting water pollution with local riverkeeper organizations on the Chesapeake Bay in Maryland. In 2013, seeing the Andromeda Galaxy for the first time with his naked eyes from atop Kitt Peak rekindled an interest in astronomy and a desire to eliminate light pollution.

Currently residing in Northern Virginia, he and his wife Chris travel extensively in the Western United States seeking dark sky locations. For several years he has assisted DarkSky as a volunteer on legal and public policy issues at the national level.
