Transcription help: letter from Stanley to Tyndall (1880): "I suppose that the Telegraphic m[ee]t[in]g will take up the ev[en]ing—otherwise the Professor c[ou]ld be spared for an hour. [Please] do not take [pains] to answer, [as I shall] [???] that the [???] is [???]."

Those were the days

I had forgotten about this Tyndall letter. It remains extremely funny.

[John Tyndall @ProfTyndall]

I see that my good friend Thomas Carlyle has been 'cancelled' by @TheLondonLib by having his bust removed, and the discounted Carlyle membership appears to have gone. I'm hoping my books won't be banned there.

[John Tyndall @ProfTyndall]

@melissaldickson I shall look forward to seeing it!

[John Tyndall @ProfTyndall]

@melissaldickson Ah! Do I appear?!

[HerschelianAstronomy @Herschels_Astro]

John Herschel was much more than just an astronomer. My latest book explains why: https://t.co/5iKIVy8HKC

[Diarmid Finnegan @diarmidf]

I wrote a short piece for @ConversationUK on @ProfTyndall's infamous Belfast Address, delivered 150 years ago this coming Monday. A different angle perhaps: https://t.co/z8Q1DTCsPA

[Diarmid Finnegan @diarmidf]

Delighted to be involved in this @HeritageWeek event. I'll be talking about @ProfTyndall 's Belfast lecture, exactly 150 years since it was delivered... Unlike Tyndall's 2 hour talk, mine will be short. The rest of time will be filled with drama and music inspired by Tyndall.

[John Tyndall @ProfTyndall]

@darwinsbulldog Well, Louisa Charlotte...

[John Tyndall @ProfTyndall]

Well, I'd never claim I discovered the greenhouse effect, as I made clear in my 1861 paper that Fourier and others have precedence. But I did provide experimental evidence for its physical mechanism. (Also I was probably born c.1822 rather than 1820).

[The Royal Society @royalsociety]

The greenhouse effect is the phenomenon that traps our Sun's heat in our atmosphere. It was first discovered by John Tyndall FRS (born #OnThisDay in 1820), and the intrepid Raghav heads into our archive to find out more about some portraits of John & his wife Louisa:

[John Tyndall @ProfTyndall]

@lapogus1 @royalsociety @tomshula I wouldn't worry too much. It does effectively trap heat, making the atmosphere warmer than it would otherwise be, (because of slowing down heat loss). But the greenhouse analogy is indeed misleading, and the term wasn't used in my day anyway.

[Roland Jackson @Roland_Jackson]

Just received my early copy of the new Henry Roscoe biography by Peter Morris and Peter Reed, which I enjoyed reading in draft. Available from OUP.

[John Tyndall @ProfTyndall]

@greenleaf6722 @darwinsbulldog I think I might have written that!

[John Tyndall @ProfTyndall]

@LeilaBelkora @darwinsbulldog I actually wrote 'selfrenouncing'!

[John Tyndall @ProfTyndall]

@virbeatum @darwinsbulldog I do believe I wrote selfrenouncing.

[John Tyndall @ProfTyndall]

@kakape @philipcball Well, to be fair, I did say it was particles with a size 'but a very small fraction of the length of a wave of violet light' so I'm not sure that would include dust.

[Roland Jackson @Roland_Jackson]

Rededication this afternoon of the gravestone of @ProfTyndall and Louisa in Haslemere, complete with reading of his poetry 1/2

I have to admit, Eunice Foote does deserve to be better known #WomensHistoryMonth

[Niels Bohr Library & Archives @AIP_Library]

This #WomensHistoryMonth, learn the story of the once-forgotten climate scientist, activist, and inventor, Eunice Foote, with help from the #InitialConditions podcast and Sir @Roland_Jackson.

The Darwin Correspondence Project has ended, but
https://t.co/hS3STMj6I0 continues to host not only the Darwin correspondence, but to put it next to that of Wallace, Faraday, Herschel, and Henslow, now with added letters by Mary Somerville!
