Reminds me of Kepler's Mysterium Cosmographicum: https://en.wikipedia.org/wiki/Mysterium_Cosmographicum
on “Isaac Newton's prediction that the world would not end before 2060 (2015)” ↗The article reproduces a famous illustration of Kepler's Platonic solids model of the Solar System from book Mysterium Cosmographicum. There is another beautiful illustration from his later book De Stella Nova that is relevant to the Great Conjunction that occurred just a few days ago: https://en.wikipedia.org/wiki/Great_conjunction#/media/File:...…
on “Crowdsourcing dynamic illustrations for a new astronomy book” ↗»Convinced that he had discovered a subtle geometric relationship between the diameters of the planetary orbits and their distances from the Sun, Kepler wrote Mysterium Cosmographicum ('the cosmic mystery'), published in 1596. The scheme worked well with the planetary distances then accepted, but even Kepler could see that it wasn't perfect. Assuming that better data on planetary orbits…
on “Johannes Kepler Music of the Spheres” ↗…"On 4 February 1600, Kepler met Tycho Brahe....Tycho guarded his data closely, but was impressed by Kepler's theoretical ideas and soon allowed him more access. Kepler planned to test his theory from Mysterium Cosmographicum based on the Mars data, but he estimated that the work would take up to two years (since he was not allowed to simply copy the data for his own use)."
on “AlphaFold 3 predicts the structure and interactions of life's molecules” ↗…telescope technology, but his efforts in moving forward new models (specifically Copernican) were a dead end, and he made no practical difference to things: Kepler was already defending Copernicus in his Mysterium Cosmographicum (1e 1596), and put forward his laws in Astronomia nova (1609), a copy of which he sent to Galileo, which Galileo promptly ignored even two decades later when he published his Dialogue (1632).
on “Salt and salary: Were Roman soldiers paid in salt? (2017)” ↗…brighter the nearer we are to its source, and the same must apply to the force of the sun: the closer the planet to it, the quicker it will move. This is his instinctive conviction, already expressed in the Mysterium Cosmographicum; but now, at last, he has succeeded in proving it. In fact he has not. He has proved the inverse ratio of speed to distance only for the two extreme points of the orbit; and his extension of this ‘Law’…
