20 September 1820: Cambridge geologist Adam Sedgwick visits Lyme Regis, noting in his journal: 'After breakfast purchase fossils of Miss Anning'. This is the earliest known reference to Mary Anning junior now taking the lead in the family fossil business run by her mother (who was also Mary Anning).
Portrait of Mary Anning wearing a green cloak and a straw bonnet tied with a red ribbon. She holds a hammer and has a basket over her arm. Portrait of Adam Sedgwick in a dark coat and academic gown. Extract from Sedgwick's journal: '20. [September] After breakfast purchase fossils of Miss Anning - walk to the Charmouth Cliffs'

🌋 On Aug 27, 1883, Krakatoa erupted with cataclysmic force. The blast was heard 3,000+ miles away, unleashed tsunamis over 30m high, and darkened skies worldwide. Global temperatures dropped, and vivid sunsets inspired artists for years.

This is a really, really important story, which is why I provided a gift link. Many people, when they think of higher education, think of elite universities. But most higher education is nonselective (i.e., they admit everyone), and a lot of it is community colleges.

“This year the NSF has awarded only $32 million, representing a 72 percent reduction. By this metric, mathematics is one of the most deeply affected subjects, second only to physics, which has seen an 85 percent reduction.“

She walked out of her immigration hearing smiling — papers in hand, standing tall. She had no idea the man waiting in the hallway was ICE. No idea she was about to be detained.

This is happening inside NYC’s immigration courts. Every day. #ICE
