Intro and Percival Lowell Background
Today I’m speaking with David Baron, a seasoned science writer who has contributed to many major American journalism outlets, including the New York Times, the Washington Post, and the Wall Street Journal. He was a longtime science correspondent for NPR, and his TED Talk on the experience of solar eclipses has been viewed millions of times. His last book, American Eclipse, won the American Institute of Physics Science Writing Award in 2018. Today we’ll be discussing his new book, The Martians: The True Story of an Alien Craze that Captured Turn-of-the-Century America.
The “alien craze” in the subtitle of your book is the story of how, for about a decade at the beginning of the twentieth century, many people came to believe that the planet Mars held not only life, but a complex civilization. The person most responsible for popularizing this view as an established scientific fact was Percival Lowell. Lowell functions as a main character in your book.
I want to thank you for joining me today. At what point in your reporting for this book did it become clear that Lowell would function as a central figure in your story?
Oh, pretty much I knew that from the start. I first learned about the so-called “canals on Mars” from Carl Sagan, when I was in high school and watched the Cosmos series on PBS. On an episode about Mars, Sagan talked about this astronomer, Percival Lowell, who at the turn of the last century saw these weird lines on Mars that he believed were irrigation canals. It’s remembered as one of the great blunders in science, because it was an idea that really took off.
What actually surprised me was not that Lowell was my main character, but just how many other people got swept up in this craze—some of them quite prominent, famous scientists and inventors who totally believed that in fact there was the civilization on Mars. It was not just Percival Lowell. It was quite a collection of interesting characters. Read more »



There can have been very few musicians who played such key roles, in so many different bands in so many different genres, as Danny Thompson. When he died at 86 in September, music lost one of its great connectors.

There are contradicting views and explanations of what dopamine is and does and how much we can intentionally affect it. However, the commonly heard notions of scrolling for dopamine hits, detoxing from dopamine, dopamine drains, and 

When you walk through the gates to enter the B-52 Victory Museum in Hanoi, you immediately find the wreckage of what has been one of the most terrifying machines ever built: an American Boeing B-52 Stratofortress. Apparently, this wreckage largely came from Nixon and Kissinger’s “Christmas Bombings” of 1972.

In June 1932, half a year before Adolf Hitler was sworn in as German Chancellor, Victor Klemperer watched Nazis on a newsreel marching through the Brandenburg Gate in Berlin. A professor of Romance languages at the Technical University of Dresden, whose area of specialization was the 18th century and the French Enlightenment, Klemperer (1881-1960) was unpleasantly gripped by this first encounter with what he termed “fanaticism in its specifically National Socialist form,” and by the “expression of religious ecstasy” he discerned in the eyes of a young spectator as the drum major passed by, balanced precariously on goose-stepping legs while he robotically beat time.
When my mother was a teenager in the early 1940s, a NY-area radio station ran a weekly contest, asking listeners to vote for their favorite singer among two: Crosby or Sinatra? How people made this preference known remains unclear to me: did you need a phone in your house to make a call to the station or was sending a postcard enough? Whatever the method, the winner would be announced each Sunday afternoon. While Sinatra often took the prize, Crosby occasionally outpaced the Jersey boy who grew up two towns south of Cliffside Park, my mother’s hometown. On those occasions, she told me, she’d stamp around my grandparents’ railroad apartment, enraged at the abject stupidity of her fellow listeners. When she’d tell this story, my mother would marvel at her parents’ forbearance, the way they’d accept these outbursts without comment, though they were highly disciplined, gloomy people for whom the idea of having an “idol,” or caring about his fate on a weekly radio show was surely alien. I like this insight into them, a softer side that I myself had only witnessed a few times.

Jersey City is a medium-size city on the West bank of the Hudson River across from Lower Manhattan. Up through the middle of the 20th century it was a port and a railroad hub but that disappeared when containerized freighter became too deep to travel that far up New York Bay. Without any freighters the railroads were no longer needed. Light industry disappeared as well. Jersey City became back-offices and bedrooms to Manhattan-based business.
We have slid almost imperceptibly and, to be honest, gratefully, into a world that offers to think, plan, and decide on our behalf. Calendars propose our meetings; feeds anticipate our moods; large language models can summarize our desires before we’ve fully articulated them. Agency is the human capacity to initiate, to be the author of one’s actions rather than their stenographer. The age of AI is forcing us to answer a peculiar question: what forms of life still require us to begin something, rather than merely to confirm it? The best answer I’ve been able to come up with is that we preserve agency by carving out zones of what the philosopher
