How Base 3 Computing Beats Binary

Three, as Schoolhouse Rock! told children of the 1970s, is a magic number. Three little pigs; three beds, bowls and bears for Goldilocks; three Star Wars trilogies. You need at least three legs for a stool to stand on its own, and at least three points to define a triangle. The number 3 also suggests a different way of counting. Our familiar base 10 decimal system uses the 10 digits from zero to 9.
