Big Picture Science for Jan. 29 2024 - Skeptic Check: Hypnosis

 

Big Picture Science - Skeptic Check: Hypnosis

REPEAT
You are getting sleeeepy and open to suggestion. But is that how hypnotism works? And does it really open up a portal to the unconscious mind? Hypnotism can be an effective therapeutic tool, and some scientists suggest replacing opioids with hypnosis for pain relief. And yet, the performance aspect of hypnotism often seems at odds with the idea of it being an effective treatment.

In our regular look at critical thinking, Skeptic Check, we ask what part of hypnotism is real and what is an illusion. Plus, we discuss how the swinging watch became hypnotism’s irksome trademark

Guests:

• David Spiegel – Professor of Psychiatry and Behavioral Sciences at the Stanford University School of Medicine
• Devin Terhune – Reader in the Department of Psychology, Goldsmiths University of London

Big Picture Science for Jan. 22 2024 - Inside Planets

Big Picture Science - Inside Planets

With planets and moons, it’s what’s inside that counts. If we want to understand surface features, like volcanoes, or their history, such as how the planet formed or whether it’s suitable for life, we study their interiors. Astronomer Sabine Stanley takes us on a journey to the centers of Venus, Saturn’s large moon Titan, Jupiter’s moon Io, and of course Earth, to help us understand how they, and the solar system, came to be.

Guest:

• Sabine Stanley - Planetary scientist at Johns Hopkins University and the author of What’s Hidden Inside Planets.

Big Picture Science for Jan. 15 2024 - Tech in Check

Big Picture Science - Tech in Check

Worried that AI will replace you? It may not seem like the Hollywood writers’ strike has anything in common with the Luddite rebellion in England in 1811, but they are surprisingly similar. Today we use the term “Luddite” dismissively to describe a technophobe, but the original Luddites – cloth workers – organized and fought Industrial Revolution automation and the factory bosses who were replacing humans with cotton spinning machines and steam powered looms. Find out what our age of AI can learn from textile workers of 200 years ago about keeping humans in the loop.

Big Picture Science for Jan. 08 2024 - Your Mind On Movies

Big Picture Science - Your Mind On Movies

By one estimate we spend a fifth of our lives watching movies or TV. In fact, we consume entertainment almost as habitually as we eat or sleep, activities that receive scientific scrutiny and study. So why not consider the effects that watching movies and TV have on our minds and bodies too? When we do, we find that they are not mere escapism. A data scientist reveals why we are what we watch, and how scientists and filmmakers work, often with competing agendas, to create sci-fi entertainment.

Guest:

• Walt Hickey - journalist, data scientist, and author of “You Are What You Watch: How Movies and TV Affect Everything”

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.

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.”

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”

Big Picture Science for Nov. 20, 2023 - The T-Rex Files

Big Picture Science - The T-Rex Files

REPEAT
T-Rex is having an identity crisis. Rocking the world of paleontology is the claim that Rex was not one species, but actually three. It’s not the first time that this particular dino has forced us to revise our understanding of the past. The discovery of the first T-Rex fossil in the 19th century taught humanity a
scary lesson: species eventually go extinct. If it happened to this seemingly invincible apex predator, it could happen to us too.

Hear how the amateur fossil hunter Barnum Brown’s discovery of T-Rex changed our understanding of ourselves, and the epilogue to the dinosaur era: how our mammalian relatives survived the potential extinction bottleneck of an asteroid impact.

Guests:

• Thomas Carr - Vertebrate paleontologist and Professor of Biology, Carthage College
• Peter Makovicky - Vertebrate paleontologist and Professor of paleontology in the Department of Earth and Environmental Sciences at the University of Minnesota
• David Randall - Author of “The Monster’s Bones: The Discovery of T Rex and How It Shook Our World”
• Steve Brusatte - Personal Chair of Paleontology and Evolution, University of Edinburgh. Author of “The Rise and Fall of the Dinosaurs” and, most recently, “The Rise and Reign of The Mammals”

Big Picture Science for Nov. 13, 2023 - Neanderthal in the Family

Big Picture Science - Neanderthal in the Family

REPEAT
Back off, you Neanderthal! It sounds as if you’ve just been dissed, but maybe you should take it as a compliment. Contrary to common cliches, our Pleistocene relatives were clever, curious, and technologically inventive. Find out how our assessment of Neanderthals has undergone a radical rethinking, and hear about the influence they have as they live on in our DNA. For example, some of their genes have a strong association with severe Covid 19 infection. Plus, how Neanderthal mini-brains grown in a lab will teach us about the evolution of Homo sapiens.

Guests:

• Svante Pääbo – Evolutionary geneticist and Director of the Max Planck Institute for Evolutionary Anthropology.
• Doyle Stevick – Associate professor of educational leadership and policies at the University of South Carolina.

Big Picture Science for Nov. 04, 2023 - Night Flight

Big Picture Science - Night Flight

Owls are both the most accessible and elusive of birds. Every child can recognize one, but you’ll be lucky to spot an owl in a tree, even if you’re looking straight at it. Besides their camouflage and silent flight, these mostly nocturnal birds, with their amazing vision and hearing, are most at home in the dead of night, a time humans find alien and scary. Ecologist Carl Safina got to know an injured baby screech owl well. Their relationship saved the owl’s life and gave Safina insider’s wisdom about these aerial hunters of the night.

Guests:

• Carl Safina – ecologist at Stony Brook University, head of the non-profit Safina Center, and author of “Alfie & Me: What Owls Know, What Humans Believe”
• Tom Damiami – natural resources interpreter, singer on Long Island, NY and leader of the Shelter Island Owl Prowl

“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.”

Big Picture Science for Oct. 23, 2023 - Like Lightning

Big Picture Science - Like Lightning

REPEAT
Every second, lightning strikes 50 to 100 times somewhere. It can wreak havoc by starting wildfires and sometimes killing people. But lightning also produces a form of nitrogen that’s essential to vegetation. In this episode, we talk about the nature of these dramatic sparks.
