Katherine Johnson died #OTD in 2020.

Her work included calculating trajectories, launch windows, and emergency return paths for Project Mercury spaceflights, including those for astronauts Alan Shepard and John Glenn, and rendezvous paths for the Apollo Lunar Module and command module on flights to the Moon. Her calculations were also essential to the beginning of the Space Shuttle program, and she worked on plans for a mission to Mars.

"We will always have STEM with us. Some things will drop out of the public eye and will go away, but there will always be science, engineering, and technology. And there will always, always be mathematics."

~Katherine Johnson (August 26, 1918 – February 24, 2020)

Johnson working at the Spacecraft Controls Branch of NASA in 1966. https://en.wikipedia.org/wiki/File:Katherine_Johnson_at_NASA,_in_1966.jpg She is seated at her desk, wearing a short-sleeved dress with a white collar and buttons. She has short, neatly styled hair and wears glasses. She is smiling while working with documents and a typewriter. The desk is filled with papers, a pen, and a binder, reflecting her analytical work. In the background, there is a large desk with more papers, a chair, and a wall featuring a circular diagram, possibly related to space missions.

Had a mathematician over for lunch today and I showed him some polygon decomposition results from my old Imperfect Congruence website.

https://gruze.org/tilings

He encouraged me to try to find a place to publish a paper describing my algorithm and suggested some journals. So possibly another longer term project.

Eg., here are two ways to decompose a 15-gon into 5 equirectangular triangles or 3 pentagons (plus rhombi).
