Steve Nadis in Quanta:
Driverless cars and planes are no longer the stuff of the future. In the city of San Francisco alone, two taxi companies have collectively logged 8 million miles of autonomous driving through August 2023. And more than 850,000 autonomous aerial vehicles, or drones, are registered in the United States — not counting those owned by the military.
But there are legitimate concerns about safety. For example, in a 10-month period that ended in May 2022, the National Highway Traffic Safety Administration reported nearly 400 crashes involving automobiles using some form of autonomous control. Six people died as a result of these accidents, and five were seriously injured.
The usual way of addressing this issue — sometimes called “testing by exhaustion” — involves testing these systems until you’re satisfied they’re safe. But you can never be sure that this process will uncover all potential flaws.

When we find words being used in a novel way, our countenances tend to stiffen. What’s going on here? Is this a euphemism? Is there a hidden agenda here?
Lindsay Hunter: As I was drafting this novel, I was thinking of it as almost a shattered windshield, or a crazy quilt. Something made of shards but that, together, was a whole thing. Initially, I had Jackie in both first- and third-person narration. I wanted readers to have access to her story, the way she’d tell it, but also glimpse a more objective truth about her. I thought that was pretty clever.

Back in 2001, immunologist Pere Santamaria was exploring a new way to study diabetes. Working in mice, he and his collaborators developed a method that uses iron oxide nanoparticles to track the key immune cells involved in the disorder.

Switching between languages, we may feel as if we are stepping from one world into another. Each language seemingly compels us to talk in a certain way and to see things from a particular perspective. But is this just an illusion? Does each language really embody a different worldview, or even dictate specific patterns of thought to its speakers?

Scientists and philosophers sometimes advocate pretty outrageous-sounding ideas about the fundamental nature of reality. (Arguably I have been guilty of this.) It shouldn’t be surprising that reality, in regimes far away from our everyday experience, fails to conform to common sense. But it’s also okay to maintain a bit of skepticism in the face of bizarre claims. Philosopher Eric Schwitzgebel wants us to face up to the weirdness of the world. He claims that there are no non-weird ways to explain some of the most important features of reality, from quantum mechanics to consciousness.
Normally at Five Books we ask experts to recommend the best books in their field and talk to us about them in an interview, either in person, by phone or via Zoom. In January 2023, we asked the AI bot, ChatGPT, to recommend books to us on the topic of AI. Being an AI doesn’t necessarily make the chatbot an expert on AI books, but we thought it might have some ideas. This week we caught up with ChatGPT to find out if there were any new AI books it wanted to recommend in the year since we spoke.
A somewhat obscure text, about 2,000 years old, has been my unlikely teacher and guide for the past many years, and my north star these last several months, as so many of us have felt as if we’ve been drowning in an ocean of sorrow and helplessness. Buried deep within the Mishnah, a Jewish legal compendium from around the third century, is an ancient practice reflecting a deep understanding of the human psyche and spirit: When your heart is broken, when the specter of death visits your family, when you feel lost and alone and inclined to retreat, you show up. You entrust your pain to the community. The text,
