Day two on Blue sky, I should define my interests a little: #histsci #histech, history of geology, geophysics, meteorology, aeronomy, near space, astronomy. I'm interested, in short, in the long term implications of Copernicus

Colleagues in history of geology (and in paleontology) will be saddened to learn that Philippe Taquet has passed.
tetzoo.bsky.social Darren Naish @tetzoo.bsky.social · 2d
Have learnt from Andrea Cau that French palaeontologist Philippe Taquet died yesterday, aged 85. Taquet published a substantial amount on north African and French #dinosaurs, including Ouranosaurus, spinosaurids, the dromaeosaurid Pyroraptor and much more.

As a consequence L believed that, like classical physics, geological dynamics are ergodic. In exploring a Newtonian state space, the earth system will return to a state in which iguanadons, ichthyosaurs, and pterodactyls roam the earth

Henry De la Beche mocked him here

Cartoon titled “Awful Changes,” representing the aftermath of “Man found only in a fossil state—Reappearance of Ichthyosauri.” Professor Ichthyosaurus lectures to a class of ichthyosaurs and plesiosaurs about the fossilized skull of a now extinct human. The skull must have belonged to “some lower order of animals” on account of the poor development of the teeth and jaws. Credit: Geological Society of London.

Tapping the XKCD sign again to explain that no, I won't be seeing an aurora tonight. Or at least I really hope not. That would be bad. :)
XKCD meaning of auroras cartoon, showing "normal" at poles, "cool and exciting" in temperate zone, "someone should go check on our satellites" in subtropics, and "A bunch of open questions in Solar-Terrestrial physics are about to be answered" at the tropics

Reading William Whewell's 1832 review of Lyell's Principles of Geology, Vol 2, in which he coined "uniformitarianism", and I just love this passage summarizing what in many modern geological textbooks would describe as the principle of uniformitarianism.

babel.hathitrust.org/cgi/pt?id=hv...
Screenshot of part of a scanned page from a 19th century scientific journal. Text reads: "Now it appears that, in the present order of things, certain changes do go on, both in the position of portions of the earth, and in the forms of certain organised beings. The volcano and the earthquake are seldom long idle; the ocean is an unremitting assailant of the solid earth; the countless host of streams and showers second his attack, on the other side, by efforts formidable from their multitude and perseverance. The coast yields; the crest of the mountain descends; large tracts of the earth tremble and change their elevation: the volcanic island lifts its head above the waves. Here, at least, are some elements of mutations in the form of the earth and of the bed of the sea. The more we examine such causes, the more constant the more extensive, the more powerful, does their operation appear. In the course of progressive ages, what effects may they not produce? And what limit are were to place to the time during which their work has proceeded? We know that this past period must be long; we know not how long. Who shall prove to use that the forces which we ourselves witness are too weak, or unfit, to produce all the facts of position which the earth's crust exhibits? Such is the reasoning of the advocate of the geological adequacy of the existing dynamical laws of the world."
