Fun fact 5/31/2016

In the 1956 article “The Magical Number Seven, Plus or Minus Two”, cognitive psychologist George A. Miller found that the average human can hold 7 ± 2 digits in  working memory.  Many believe that this is, in part, why Bell Labs determined that phone numbers should be seven digits.
