Sometimes I wish we lived in a world where DjVu was common for book scans and we didn't have to deal with buggy and bloated PDFs. Instead I get to use this slick piece of 2006 vintage software with this incredible splash screen maybe 2–4 times a month.

These are the brown marmorated shield bug eggs that hatched on my ficus last year. The eggs were hauntingly pearl white.

At least this contraption from Brazil is above where the water comes out. The first time I saw a tankless electric hot shower unit in the UK I was shocked (figuratively) that it was mounted a shoulder height.

Omg I’m so here for this diagram, “Distribution of subject focus at 40 German materials science and engineering adjacent institutions” between Werkstoffwissenschaft (materials science), mechanical/electrical engineering, and physics/chemistry in 1994: link.springer.com/article/10.1... #histsci

Poking around the the term "scientific consensus" means different things in different periods. In the 19th c. the phrase "consensus of opinion" is more common, by the 1940s it's a term of art about public testimony, eg in court or to Congress.

Since "whipsaw" has become a trending word, I looked it up: figuratively it either means "victimize in two opposite ways at once" or by two causes (i.e., two people holding a saw; MW+OED) or "characterized by rapid fluctuation" (i.e., the saw is moving up and down; OED). These are very different!

Milieus of Minutiae from UVA Press is out, and I got my copy! This began as a workshop on details and small things in literature, philosophy, and science. My chapter, "Confronting the Limits of Optical Interpretation," is my new take on the history of the microscope. DM me if you want a scan! 🧪 🗃️ 🐋🌱
