- The Scarlet Plague (Wikipedia)
The Scarlet Plague is a post-apocalyptic fiction novel by American writer Jack London, originally published in The London Magazine in 1912. The book was noted in 2020 as having been very similar to the COVID-19 pandemic, especially given London wrote it at a time when the world was not as quickly connected by travel as it is today.
- Archimedean solid (Wikipedia)
In geometry, an Archimedean solid is one of 13 convex polyhedra whose faces are regular polygons and whose vertices are all symmetric to each other. They were first enumerated by Archimedes. They belong to the class of convex uniform polyhedra, the convex polyhedra with regular faces and symmetric vertices, which is divided into the Archimedean solids, the five Platonic solids (each with only one type of polygon face), and the two infinite families of prisms and antiprisms. The pseudorhombicuboctahedron is an extra polyhedron with regular faces and congruent vertices, but it is not generally counted as an Archimedean solid because it is not vertex-transitive. An even larger class than the convex uniform polyhedra is the Johnson solids, whose regular polygonal faces do not need to meet in identical vertices.
