Blog Carnival

Welcome to the 20th edition of the Mathematics and Multimedia Blog Carnival. Here are the posts I have collected this month — some from the Blog Carnival site and some from my RSS feed.

Before we begin a carnival, let’s have some trivia about the number 20.

  • The number of sectors in a dartboard.
  • The atomic number of calcium.
  • It is the smallest primitive abundant number
  • The number of faces of an icosahedron
  • Can be written as the sum of the three Fibonacci numbers: 13 + 5 + 2
