Undiscovered - Six Degrees
Are you just six handshakes away from every other person on Earth? Two mathematicians set out to prove we’re all connected.
You have probably heard the phrase “six degrees of separation,” the idea that you’re connected to everyone else on Earth by a chain of just six people. It has inspired a Broadway play, a film nerd’s game, called “Six Degrees of Kevin Bacon”...and even a No Doubt song! But is it true? In the ‘90s, two mathematicians set out to discover just how connected we really are—and ended up launching a new field of science in the process.

A version of psychologist Stanley Milgram’s “Letter Experiment” mailings. “Could you, as an active American, contact another American citizen regardless of his walk of life?” Milgram and his team wrote. They asked for recipients' help in finding out. Accessed at the Yale University archives. (Credit: Elah Feder)
