In 1967, Stanley Milgram of Harvard performed an ingenious experiment, demonstrating that, although our world is highly clustered, it is still very connected: everyone is on average approximatrely six handshakes away from any other person on the planet; six degrees of separation. It would be interesting to repeat Milgram’s experiment in our days. How small is our small world today? On the one hand, thanks to globalization, the world is becoming more and more interconnected. The average number of friends (what the last word means) of a randomly chosen person grows with time. On the other hand, the total population of the planet grows much faster than exponentially. What is happening with our world? Is it expanding or shrinking in the Milgram’s sense?
