I'm a neuro-ophthalmologist at Rutgers. I despise EMR & love to teach students/residents how to examine the brain directly w/ an ophthalmoscope (& indirectly w/ a detailed neurologic exam). Wrote "Finding Einstein's Brain" but damn if it isn't lost again!

Thomas Huxley-aka Darwin's bulldog- used Waterhouse Hawkins' marvelous drawing (Gibbon 2x) in 1863 to promote evolution
Alas Hawkins was anti-evolution but he was the first to mount and restore dinosaurs for the Crystal Palace exhibit 1852-54

Neanderthals had larger brains (1500 cc) than Homo sapiens (1350 cc).
If we de-extinct them, I'm pretty sure they wouldn't need ChatGPT.
If they don't come back, don't worry. Modern humans have 1-4% Neanderthal DNA in their genomes.

Mani pedi & more
It's not just their nails. Sloth nervous systems are "wired in reverse" for reflex hanging.
Antigravity muscles prevail w/midbrain lesions.Decerebrate cats "stand" erect w/rigid extensor muscles but in 1926 it was found that decerebrate sloths hang w/rigid flexor antigravity muscles

Drove 15 miles today to a schist outcrop along Rte 1A in Ellsworth ME where in 1864 Louis Agassiz found scratches/furrows pointing north in support of his theory of continental glaciation 13K-25K yrs ago.
Glacial scratches can be seen today!

Alice's Adventures Underground. Did Lewis Carroll draw his own migraine aura?
Carroll first mentions migraine "fortifications" in his 1885 diary but he consulted an oculist in 1852.
Did his 1862 drawing of mock turtle & gryphon anticipate H. Airy's iconic 1870 tracing of his own migraine teichopsia?

The MAGA-ized Smithsonian can revise American mores- just not on my dime. I'm not subscribing.
MAGA need not worry about my dime. Creationists aside, they're gonna love Ales Hrdlicka's (physical anthropologist/eugenicist emeritus) scavenged racial brain collection (WaPo 8/14/2023) & Wall of Skulls.

Losing my Accommodation
Mid-40s is a visually dangerous age as lens gets stiffer, diopters of accommodation <4, & arms are too short
If progressives don't cut it, consider tri-focals or monovision refraction making one eye near-sighted & the other far-sighted (not a fan)

Academic conflicts - "because the stakes are so low"
Easy. If a scientist read a typical IMRAD format paper, the audience would achieve REM sleep in seconds

Try JK Galbraith,econ prof:"There seems little question that in 1929,modifying a famous cliche,the economy was fundamentally unsound"

What we have here is a failure to communicate (to an on-line audience):
1.Rolling Stones:"to get my fair share of abuse"
2.Walt Whitman:"sound my barbaric yawp over the roofs"
3.Vance Packard: advertising's "Theory of the Marginally Committed"

After grinding tons of uranium ore to discover radium & polonium, Marie,her husband Pierre, and her 1900 lab notebook- w/ ~3.2 microCuries of radium 226 (1/2 life 1600 yrs)- were all radioactive.

Saw Jurassic World Rebirth last week. If birds, esp. cassowaries, are dino descendants, did dinos look out at the world with bird retinas- lots of cones for diurnal vision & a pecten (function unknown)?

..Hooke himself survived until 1703.
The likeliest vector for the Great Plague was xenopsylla cheopis (oriental rat flea). The responsible gram-negative bacterium, Yersinia pestis, was not identified until 1894 during an outbreak in Hong Kong.

Lost in Translation?
When we last checked, in 1947 Einstein's take-away on the slime mold films of my old bio prof JT Bonner was mostly in German. Not true!
E: "How was the life cycle controlled so that it was the same each generation?"
E "got it" & Bonner "cursed myself" for not taking notes!
