Transcription help: need help deciphering a word in this 1864 letter from John Tyndall to a teenager interested in science. "4. A bar of copper sets across the [????] joining the magnetic poles because its two ends are repelled by the poles and retreat from them as far as possible." #HPS #histsci

Yesterday I finished rereading Janet Browne's two volume biography of #CharlesDarwin, published in 1995 and 2002. Now ready to check out the new, condensed, single-volume edition being published by @princetonupress.bsky.social at the end of this month. #HPS #histsci #books

I wish searches here for "John Tyndall" brought up more posts about the C19th scientist rather than the C20th fascist. Photo: portrait of Tyndall included in 20 Aug. 1874 issue of @nature.com (the week of his infamous "Belfast Address" at meeting of BAAS/@britsciassoc.bsky.social). #HPS #histsci

On our walk to Keston we passed this tribute to local lad Charles Darwin in Bromley town centre. Sadly, someone’s chucked silver paint around Chuck’s legs and feet. Probably a Reform supporter made angry by the thought of evolving. And B&Q, presumably, were out of red-white-and-blue paint. #Bromley

31-May: On this day in 1837, Charles Darwin presented his theory of coral reef formation.  #HistSci friendsofdarwin.com/articles/dar...

OTD in 1837, Charles Darwin first presented his theory of how coral reefs are formed to the Geological Society of London. The event marked his public debut as a theorist. L: hand-colored section of Cocos Island atoll. R: diagram of the same from his 1842 book (Darwin Online). 🌱🐋🧪⚒️🗃️🧠 #HistSTM

When Charles Darwin was having a rough day:

Today in 1868, Darwin wrote to a friend, "It drives me mad & I know it does you too, that one has no time for reading anything beyond what must be read: my room is encumbered with unread books." 📚🧪

Charles Darwin has rarely felt more relatable... #OnThisDay #TooManyBooks #Darwin #histsci #histSTM 📚

Election Day! Spent two hours today as a public observer at the Clackamas County Elections Office in Oregon City, learning how the ballot are processed. Pretty streamlined with dedicated workers!

May 16, 1861, botanist John Stevens Henslow died #OTD. An important mentor to a young Charles Darwin. Apart introducing him to #botany 🌼 he also taught him some basic #geology ⚒

Thomas H Huxley was born OTD in 1825. The idea of “warfare” between science and religion is suspect, but it works for H. Protestantism lacks “a trace of any desire to set reason free. The most that can be discovered is a proposal to change masters” from the Pope to the Bible. 🧪🌱🐋 #HistSTM #EvoBio

New for @undark.org: "What I Learned from Teaching Darwin" "For Darwin at least, science was a conversation between humans and nature, more than it was an industry. I wish that were true today, for all of us." undark.org/2026/04/23/o...

19-Apr: ☹️ On this day in 1882, Charles Darwin died, age 73. Here’s the sad story… friendsofdarwin.com/articles/dar... #HistSci

Charles Darwin died OTD in 1882. Stories of a deathbed renunciation of his doubts about Christianity and recantation of his theory circulated widely (mostly in the US, predictably). They were, however, lies. He was buried in Westminster Abbey, next to John Herschel. 🧪🌱🐋 #HistSTM #Evobio #PhilSci

April 19, 1837, Richard Owen published the description of Toxodon based on a large fossil skull purchased by Charles Darwin in South America. Darwin paid 18 pence for it noting in his journal that it was "one of the strangest animals ever discovered" ...

Charles Darwin died on this day in 1882. All sorts of info regarding his funeral a week later at Westminster Abbey can be had at this page from @darwin-online.bsky.social: darwin-online.org.uk/EditorialInt...

Charles Darwin died #OTD in 1882. His son George wrote to John Tyndall 6 days later: "I hope you will have received the tickets for the Abbey... I am sure you sympathise with my Mother & her children." Tyndall arrived late to the funeral and wasn't able to sit among other friends of #CharlesDarwin.

I checked out Change is in the Air from my local library & wonder if this is the 1st depiction of John Tyndall in a children's book. Possibly also in Foote Was First! illus. by @amyjunebates.bsky.social. Footeprint is a novel-in-verse by @lindsayhmetcalf.bsky.social, not sure if any illustrations.

🎨 Colour, observation, and distance 🐦️ How did Charles Darwin describe colour in the field? In our newest BJHS issue, Joyce Dixon examines Darwin’s use of Werner’s Nomenclature of Colours during the Beagle voyage—and what it meant for scientific communication.
