China's Grip on Rare-Earth Elements and the Future of Global Energy Security

China's Grip on Rare-Earth Elements and the Future of Global Energy Security

To build electric vehicles, solar panels, cell phones, and millions of other devices means the world must dig more mines to extract lithium, copper, and other vital building blocks. But mines are deeply unpopular, even as they have a role to play in fighting climate change and powering crucial technologies.

Shermer and Scheyder discuss: • How much rare earth metals will we need by 2050, 2100, and beyond? • How do lithium-ion batteries work compared to lead-acid? What are the alternatives? • Will EVs completely replace all other cars? • Can renewables completely replace fossil fuels without nuclear? • How mining works in the U.S., China, Chile, Russia, elsewhere.

Ernest Scheyder is a senior correspondent for Reuters, covering the green energy transition and the minerals that undergird it. He previously covered the US shale oil revolution, politics, and the environment at the Associated Press.

2. Michelle Feynman — The Quotable Feynman & His Van

2. Michelle Feynman — The Quotable Feynman & His Van

Nobel Prize-winning physicist Richard P. Feynman (1918–88) was a towering scientific genius who could make himself understood by anyone and who became as famous for the wit and wisdom of his popular lectures and writings as for his fundamental contributions to science. The Quotable Feynman is a treasure-trove of this revered and beloved scientist’s most profound, provocative, humorous, and memorable quotations on a wide range of subjects edited by his daughter, Michelle Feynman, who will discuss her father’s life and legacy. In addition, physicist Seamus Blackey will bring Feynman’s van, newly restored and recently featured on The Big Bang Theory, so you can get your photograph taken with the famous vehicle featuring Feynman diagrams. Order The Quotable Feynman from Amazon. Our special guest at this salon will be: Dr. Leonard Mlodinow, physicist and author of Feynman’s Rainbow: A Search for Beauty in Physics and in Life and The Upright Thinkers: The Human Journey from Living in Trees to Understanding the Cosmos.

1. Dr. Lisa Randall — Dark Matter and the Dinosaurs: The Astounding Interconnectedness of the Universe

1. Dr. Lisa Randall — Dark Matter and the Dinosaurs: The Astounding Interconnectedness of the Universe

The renowned Harvard cosmologist and theoretical physicist explores a scenario in which a disk of dark matter—the elusive stuff in the universe that interacts through gravity like ordinary matter, but that doesn’t emit or absorb light—dislodged a comet from the Oort cloud that was ultimately responsible for the dinosaurs’ extinction. Dr. Lisa Randall teaches us an enormous amount about dark matter, our Universe, our galaxy, asteroids, and comets—and the process by which scientists explore new concepts.
