It may be a bit soon but I've produced a #calendar for #2025. Unlike previous editions, which featured some of my photographs, this one contains #illustrations to do with #mathematics, #geometry, #physics and #engineering applications.

My wife was looking at the properties of #ellipses such as the one where the sum of the distance of all points on the #ellipse from the two foci are the same and how that relates to the standard equation of an ellipse and so I showed her using my scribbly #handwriting and untidy drawings. Unfortunately, it didn't quite hit home and so I wrote these notes up neatly using #LaTeX, which did do the trick.
To put it up here, I converted the #PostScript pages to #PNG format using #GNU #Gimp and the figure was produced using #Tgif.

🇦🇺 Die ∼32 im Park Hotel inhaftierten #Refugees bekommen gerade viel Aufmerksamkeit.
Für alle, die das erst jetzt erfahren haben: Seit 9 Jahren sind über 200 Menschen offshore in #PNG🇵🇬 & #Nauru🇳🇷 und 70 onshore; die in PNG wurden von #Australien allein gelassen.

While there is a lot of focus on the 32 or so refugees detained in Park Hotel, for those who are just hearing about this, after 9 years there are still over 200 people offshore in PNG and Nauru, and 70 onshore. Those in PNG have been abandoned there by Australia.

If anyone hates having to deal with .webp files as much as I do, here's a firefox addon to request an original .jpg or .png file instead.
