Big Picture Science for Dec. 25, 2023 - Iron, Coal, Wood

Big Picture Science - Iron, Coal, Wood

REPEAT
Maybe you don’t remember the days of the earliest coal-fired stoves. They changed domestic life, and that changed society. We take you back to that era, and to millennia prior when iron was first smelt, and even earlier, when axe-handles were first fashioned from wood, as we explore how three essential materials profoundly transformed society.

We were once excited about coal’s promise to provide cheap energy, and how iron would lead to indestructible bridges, ships, and buildings. But they also caused some unintended problems: destruction of forests, greenhouse gases and corrosion. Did we foresee where the use of wood, coal, and iron would lead? What lessons do they offer for our future?

Guests:

• Jonathan Waldman – Author of Rust: The Longest War.
• Ruth Goodman – Historian of British social customs, presenter of a number of BBC television series, including Tudor Monastery Farm, and the author of The Domestic Revolution: How the Introduction of Coal into Victorian Homes Changed Everything.
• Roland Ennos – Professor of biological sciences at the University of Hull and author of The Age of Wood: Our Most Useful Material and the Construction of Civilization.

Big Picture Science for Dec. 18, 2023 - The Ocean’s Genome

 

Big Picture Science - The Ocean’s Genome

After helping to sequence the human genome more than twenty years ago, biochemist Craig Venter seemed to recede from the public eye. But he hadn’t retired. He had gone to sea and taken his revolutionary sequencing tools with him. We chatted with him about his multi-year voyage aboard the research vessel Sorcerer II, its parallels to Darwin’s voyage, and the surprising discoveries his team made about the sheer number and diversity of marine microbes and their roles in ocean ecosystems.

Guests:

• Craig Venter - Genomicist, biochemist, founder of the J. Craig Venter Institute, and co-author of “The Voyage of Sorcerer II: The Expedition that Unlocked the Secrets of the Ocean’s Microbiome.”
• Jeff Hoffman - Lab manager at the J. Craig Venter Institute and expedition scientist on the Sorcerer II expedition.

Big Picture Science for Dec. 11, 2023 - Skeptic Check: Naomi Klein

Big Picture Science - Skeptic Check: Naomi Klein

Our information age is increasingly the disinformation age. The spread of lies and conspiracy theories has created competing experiences of reality. Facts are often useless for changing minds or even making compelling arguments. In this episode, author Naomi Klein and science philosopher Lee McIntyre discuss why the goal – not simply the byproduct - of spreading disinformation is to polarize society. They also offer ideas about how we might find our way back to a shared objective truth.

Guests:

• Naomi Klein - Associate professor of Geography at the University of British Columbia and a co-director at the Center for Climate Justice. Author of Doppelganger: A Trip Into the Mirror World
• Lee McIntyre - Philosopher of science and a research fellow at the Center for Philosophy and the History of Science at Boston University, and author of Post-Truth and On Disinformation.

Big Picture Science for Dec. 04, 2023 - End of Eternity

Big Picture Science - End of Eternity

REPEAT
Nothing lasts forever. Even the universe has several possible endings. Will there be a dramatic Big Rip or a Big Chill­–also known as the heat death of the universe–in trillions of years? Or will vacuum decay, which could theoretically happen at any moment, do us in? Perhaps the death of a tiny particle – the proton – will bring about the end.

We contemplate big picture endings in this episode, and whether one could be brought about by our own machine creations.

Guests:

• Anders Sandberg – Researcher at the Future of Humanity Institute at the University of Oxford
• Katie Mack – Assistant professor of physics at North Carolina State University, and the author of “The End of Everything, Astrophysically Speaking.”
• Brian Greene – Brian Greene, professor of physics and mathematics at Columbia, and author of “Until the End of Time: Mind, Matter, and Our Search for Meaning in an Evolving Universe”
