For the #Spacetober#histsci We remember him for his role in the Scientific Revolution, & his 3 laws of planetary motion in particular. His laws modified Copernicus’ heliocentric model; he replaced the 🧵1/n

My linocut portrait of Johannes Kepler on cream coloured washi paper. Kepler is in Renaissance garb printed in indigo. He holds a compass and rests his hand on his model of nested Platonic solids from Mysterium Cosmographicum, printed in gold ink. Above that in silver in are 7 musical staves with notes next to symbols for related planetary bodies: Mercury, Venus, Earth and Moon, Mars, Jupiter and Saturn. Over his other shoulder are 3 schematic diagrams drawn in ellipses (oriented with the semi-major axes horizontal) in magenta. The top one relates to his first law and shows an ellipse cut in two horizontally, the two foci labelled F and F’ and a triangle drawn to a point P on the ellipse (FPF’). The middle ellipse (2nd law) shows the Sun at a focus, and a series of circles on the ellipse as a planet such that the sections are equal area and alternate colouring (magenta or none) like a peppermint. The bottom ellipse (3rd law) is cut in half with semi-major and semi-minor axes shown

circular orbits with elliptical ones & described velocities of planets. Today we know them as: 1) Planetary orbits are ellipses with the Sun as one of the foci (top magenta ellipse) 2) A line from Sun to planet sweeps out equal areas in equal time periods (middle ellipse) 3) The square of the 🧵2/
