Big Picture Science for Dec. 30, 2024: Skeptic Check: Naomi Klein

Big Picture Science - Skeptic Check: Naomi Klein

REPEAT
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. 23, 2024 - 2024: Extraordinary Ordinary Objects

Big Picture Science - 2024: Extraordinary Ordinary Objects

REPEAT
“To live is to count and to count is to calculate.”  But before we plugged in the computer to express this ethos, we pulled out the pocket calculator. It became a monarch of mathematics that sparked a computing revolution. But it’s not the only deceptively modest innovation that changed how we work and live. Find out how sewing a scrap of fabric into clothing helped define private life and how adding lines to paper helped build an Empire. Plus, does every invention entail irrevocable cultural loss?

Guests:

• Keith Houston – author of “Empire of the Sum: The Rise and Reign of the Pocket Calculator.”
• Hannah Carlson – teaches dress history and material culture at the Rhode Island School of Design, author of “Pockets: An Intimate History of How We Keep Things Close.”
• Dominic Riley – bookbinder in the U.K.

Big Picture Science for Dec. 16, 2024 - 2024: Our Space Odyssey

Big Picture Science - 2024: Our Space Odyssey

This year has been a spectacular one for celestial phenomena. The northern lights delighted in unexpected ways while a total solar eclipse cast a shadow across North America. Those events were enough to make it a memorable year, but 2024 also shook up our understanding of the universe. A new reading of Voyager 2 data may explain Uranus’s weird magnetic field. And the impressive James Webb Space Telescope has detected an early and incredibly distant galaxy. Join us in our look back at some of the top space news from 2024.

Guests:

• Andrew Fraknoi – Professor of Astronomy at the Fromm Institute at the University of San Francisco and SETI board member
• Jamie Jasinski - space plasma physicist for the NASA Jet Propulsion Laboratory, and author of a recent paper re-examining data from the Voyager 2 mission, published in Nature.
• Phil Plait - astronomer, author, science communicator and frequent contributor at Scientific American.

Big Picture Science for Dec. 09, 2024 - A Real Gas

Big Picture Science - A Real Gas

Just because something is invisible doesn’t mean it isn’t there. We can’t see gases in our atmosphere, such as carbon dioxide, oxygen, and nitrogen, but we benefit from their presence with every breath we take. From the bubbles that effervesce in soda to the vapors that turn engines, gases are part of our lives. They fill our lungs, give birth to stars, and… well, how would we spot a good diner without glowing neon? In this episode, a materials scientist shares the history of some gaseous substances that we don’t usually see, but that make up our world.

Guest:

• Mark Miodownik – Professor of materials and society at the University College London and the author of “It’s a Gas: The Sublime and Elusive Elements That Expand Our World.”

Big Picture Science for Dec. 01, 2024 - Going Multicellular

 

 

Big Picture Science - Going Multicellular

REPEAT
Imagine life without animals, trees, and fungi. The world would look very different. But while the first life was surely single-celled, we don’t know just how it evolved to multicellular organisms. Two long-term experiments hope to find out, and one has been running for more than 35 years. Hear about the moment scientists watched evolution take off in the lab, and how directed evolution was used to create a multicellular organism. Also, how single embryonic cells become humans, and what all of this says about the possibility of life on other worlds.

Guests:

• Jeff Barrick – molecular scientist at the University of Texas at Austin where his lab oversees the Long-Term Evolution Experiment that’s been running since 1988.
• Will Ratcliff – an evolutionary biologist at Georgia Institute of Technology
• Ben Stanger – cancer researcher, professor of medicine and developmental biology at the University of Pennsylvania and author of “From One Cell: A Journey into Life’s Origins and the Future of Medicine.”
• Joseph L. Graves – evolutionary biologist and geneticist at North Carolina Agricultural and Technical State University and author of “A Voice in the Wilderness: A Pioneering Biologist Explains How Evolution Can Help Us Solve Our Biggest Problems.”
