@history_dame And they sometimes put on public display the Book of Common Prayer in which the Rector, Jacob Duché, crossed out the name of the King on July 4, 1776 – an act of treason. Duché was also chaplain to the Continental Congress.

@HomerPavlos Καλή Ανάσταση

This wouldn't be a problem if we simply read the papers that we cite. Isn't this what we all teach our students to do??

Hallucinated citations are polluting the scientific literature. What can be done? https://t.co/x7LxPyhm81

@chrisshipitv @JakeSherman Didn't Charles II have the last laugh, though? In the Restoration, Cromwell's body was disinterred from the Abbey for decapitation; the body was burned and his head is buried at a secret location in the chapel of Sidney Sussex College, Cambridge. Don't mess with the King!

@JohnBolaris A quick note of appreciation for your knowledge, insight, and passion for meteorology. It would be great to see you on air again someday, but following you on X is the next best thing!

@RENEGADEARTH494 @A_K_Mandhan ...and, if recollection serves, a jewelry shop and a flower shop for those times when a significant-other would like to pick up something because they'll be home late...!

@briannalyman2 Your summaries are fantastic! I grew up in Boston (the Freedom Trail was part of my 4th grade curriculum) and I have been living in Philadelphia for nearly 40 years. I am looking forward to hearing more about Philly history in the coming year...

@Mr72Capital @afneil To be fair, I've never seen the T5 Concorde Lounge crowded, or even half-full. Additionally, the Lounge staff were very helpful when my son missed a connection last year, they worked everything out seamlessly. For better or worse, I will be loyal to @British_Airways to the end!

After giving a lecture earlier today at the @UoMMIB in Manchester, UK, my hosts took me to the Midland Hotel, where in 1904 CS Rolls and FH Royce met to form the venerable Rolls Royce company! @rollsroycecars

I had a delightful visit to ⁦@ITALFARMACO⁩ in Milan yesterday to discuss our mutual interests in HDACs. Their inhibitor Givinostat was recently approved for the treatment of Duchenne muscular dystrophy.
