Greetings! Since I’m a historian of science, I thought my first post in this space should celebrate the cyanometer, the device Alexander von Humboldt (among others) used to determine just how blue any sky actually is

“Over the past four decades, Republican and Democratic administrations have used different estimates of the monetary value of a human life in cost-benefit analyses. But until now, no administration has counted it as zero.”

“The Ministry of Peace concerns itself with war, the Ministry of Truth with lies, the Ministry of Love with torture and the Ministry of Plenty with starvation. These contradictions are not accidental…they are deliberate exercises in doublethink.” Orwell, “1984”

Ben Franklin's World @bfworld.bsky.social · Aug 25
Franklin didn’t just invent a stove—he invented five. Each one was designed to conserve fuel and control smoke. His final models in Europe? Built to burn coal cleaner.

Sound familiar? 📻 Listen to @joycechaplin.bsky.social‬ break it down: benfranklinsworld.com/412

How did Benjamin Franklin’s stove save energy? What does it reveal about wood, trees, and attempts to control the climate?

Sen. Hagerty on his legal rationale for not counting undocumented immigrants in the census: "There's a constitutional interpretation I think that has been misapplied that goes back to slavery days and what portion of a person is going to be counted."

The first anti-vaxxers worried that the original vaccine, which used cowpox against smallpox, would turn them into cows, a bizarre fear depicted here by caricaturist James Gillray—today is his day.

Last was "The Franklin Stove" by @joycechaplin.bsky.social, who uses Ben Franklin as a lens into larger scientific, political, social, and industrial trends around heating/climate. This is one of the best histories I've ever read. Highly recommend

Your annual reminder of science’s foundational role in US history: on July 4, 1776, the Declaration of Independence was first publicly read, in Philadelphia, from a platform originally built for astronomers to observe the 1769 Transit of Venus—science was the literal platform for revolution
