Quantum Refuge

Qasem Waleed is a 28-year-old physicist who has lived in Gaza his whole life. In 2024, he joined a chorus of Palestinians sharing videos and pictures and writing about the chaos and violence they were living through, as Israel’s military bombardment devastated their lives. But Qasem was trying to describe his reality through the lens of the most notoriously confusing and inscrutable field of science ever, quantum mechanics. We talked to him, from a cafe near the Al-Mawasi section of Gaza, to find out why. And over the course of several conversations, he told us how this reality-breaking corner of science has helped him survive. And how such unspeakable violence actually let him understand, in a visceral way, quantum mechanics’ most counter-intuitive ideas.  Special thanks to Katya Rogers, Karim Kattan, Allan Adams, Sarah Qari, Soren Wheeler, and Pat Walters EPISODE CREDITS:  Reported by - Lulu Miller Produced by - Jessica Yung with mixing help from - Jeremy Bloom Fact-checking by - Emily Kreiger and Edited by  - Alex Neason EPISODE CITATIONS: Videos -  * A Brief History of Quantum Mechanics with Sean Carroll, The Royal Institution [https://www.youtube.com/watch?v=5hVmeOCJjOU] (https://www.youtube.com/watch?v=5hVmeOCJjOU [https://www.youtube.com/watch?v=5hVmeOCJjOU]) * Introduction to Superposition, with MIT’s Allan Adams [https://www.youtube.com/watch?v=lZ3bPUKo5zc] (https://www.youtube.com/watch?v=lZ3bPUKo5zc [https://www.youtube.com/watch?v=lZ3bPUKo5zc]) * The Quantum Wavefunction, Explained [https://www.youtube.com/watch?v=sOI4DlWQ_1w](https://www.youtube.com/watch?v=sOI4DlWQ_1w [https://www.youtube.com/watch?v=sOI4DlWQ_1w]) Articles -  Read a selection of Qasem’s published essays about his life in Gaza and the quantum world:  * I am stuck in a box like Schrodinger’s in Gaza [https://www.aljazeera.com/opinions/2024/12/19/i-am-stuck-in-a-box-like-schrodingers-in-gaza] (https://zpr.io/ALDVi9E5bRt8 [https://zpr.io/ALDVi9E5bRt8])  * Israel has turned Gaza’s summer into a weapon [https://www.aljazeera.com/opinions/2025/7/17/israel-has-turned-gazas-summer-into-a-weapon] (https://zpr.io/YS4WK4hVQC5T [https://zpr.io/YS4WK4hVQC5T]) * The Physics of Death in Gaza [https://electronicintifada.net/content/physics-death-gaza/46081] (https://zpr.io/hxsgxicVqPAd [https://zpr.io/hxsgxicVqPAd])  Signup for our newsletter!!

The Wubi Effect

When we think of China today, we think of a technological superpower. From Huawei and 5G to TikTok and viral social media, China is stride for stride with the United States in the world of computing. However, China’s technological renaissance almost didn’t happen. And for one very basic reason: the Chinese language, with its 70,000 plus characters, couldn’t fit on a keyboard. Today, we tell the story of Professor Wang Yongmin, a hard-headed computer programmer who solved this puzzle and laid the foundation for the China we know today. Special thanks to Martin Howard.

The Glow Below

A call to oceanographer Edie Widder about a fish with a very odd immune system quickly becomes something else: a dive into the deep sea, into a world of brilliant light. But down there, the light doesn’t behave like light -- it sparkles and glows, but also drips, squirts, and dribbles. Today, find out how creatures make the light and how they use it, from hunting and hiding to maybe even … talking. And hear about a series of mysterious moments where Edie goes from studying the creatures to becoming one of them.  EPISODE CREDITS:  Hosted by - Molly Webster Reported by - Molly Webster Produced by - Maria Paz Gutierrez with help from - Molly Webster Fact-checking by - Diane A.

What Up Holmes?

Love it or hate it, the freedom to say obnoxious and subversive things is the quintessence of what makes America America. But our say-almost-anything approach to free speech is actually relatively recent, and you can trace it back to one guy: a Supreme Court justice named Oliver Wendell Holmes. Even weirder, you can trace it back to one seemingly ordinary eight-month period in Holmes’s life when he seems to have done a logical U-turn on what should be say-able.  Why he changed his mind during those eight months is one of the greatest mysteries in the history of the Supreme Court. (Spoiler: the answer involves anarchists, a house of truth, and a cry for help from a dear friend.)  Join us in an episode we originally released in 2021, as we investigate why he changed his mind, how that made the country change its mind, and whether it’s now time to change our minds again. Special thanks to Jenny Lawton, Soren Shade, Kelsey Padgett, Mahyad Tousi and Soroush Vosughi.

Content Warning

Over the past five years TikTok has radically changed the online world. But trust us when we say, it’s not how you’d expect. Today we continue our yearslong exploration of what you can and can’t post online. We look at how Facebook’s approach to free speech has evolved since Trump’s victory. How TikTok upended everything we see. And what all this means for the future of our political and digital lives.
