The Jan 5th issue has a cartoon about Pythagoras cutting through a rectangular field.

Reader KH recalled a real-life incident where the students used their math knowledge to create their own path 😄

59th issue. And what’s cool about 59?

• 59 is the atomic number of Praseodymium - symbol Pr

• There is no country with international calling code 59. Instead there are 10 countries with 590-599 country code

• There are 59 stellations of the regular icosahedron - a 20 sided solid

  • Stellation for polygons and polyhedra is the process of extending edges or faces until they meet to form a new polygon or polyhedron.

  • For example, there are no stellations of the cube, because non-adjacent faces are parallel and thus cannot be extended to meet in new edges.

  • The image below is represents the 59 stellations.

That’s it for this issue.
