The experience of meeting a complete stranger with whom we have apparently little in common and ï¬nding unexpectedly that we share a mutual acquaintance is one with which most of us are familiarâ€”â€œItâ€™s a small world!â€ we often say. In the 1960s, noted psychologist Stanley Milgram quantified this small world phenomenon by demonstrating that randomly selected individuals from almost anywhere in the United States were â€œconnectedâ€ via a chain of no more than six intermediate acquaintances. In this talk, we will analyse the social network models proposed by â€œWatts & Strogatzâ€ and â€œKlienbergâ€ that attempt to explain this phenomenon.
