And stayed tuned for some surprise announcements below!👇🧵

We started #Week1 of #VisualAlgebra with a few quotes from "A Mathematician's Apology" on the beauty of mathematics, and then saw Cayley diagrams for the symmetries of the rectangle and triangle.
In #Week2 of #VisualAlgebra, we explored the Rubik's cube, more Cayley diagrams, group presentations, the impossibility of the word & halting problems, and we classified all frieze groups.

Not until the very end of the month did the number of (confirmed) daily cases skyrocket📈 #Week9

Many regions had school-breaks in late February that cluster travel ⛷️✈️ by region and time! #vinterferie #sportlov
This creates the potential for large-regional outbreaks!
➡️Multiple independent simultaneous introductions of #COVID19 to the same geographic location❗️❗️
