There used to be a theory saying that anyone in the world was, on average, six steps away from any other person on Earth. This means that a chain of 'a friend of a friend' can be made to connect any two people in six steps.
There was a play and even a film about this.
But globalization has changed this too: Facebook and the University of Milan have carried out a new research that proves the new distance is now only 4.74. The results were published on Facebook site last Monday.
To calculate this, they used the 721 million active users of FB (one tenth of the world's population) and the relationships between them (69 billion).
It's a small small world... and getting smaller!

Romance isn't necessarily red roses and poems, it can also be seen from a more 'logical' or 'scientific' way. Do you know who all these people are?
Ada Lovelace, one of the two women in the group, was the only legitimate child of the poet Lord Byron (with Anne Isabella Milbanke) and is considered the world's first computer programmer. Alan Turing, mathematician and cryptanalyst, played an important role in the development of computer science. Tesla, who was Serbian, contributed significantly to the birth of commercial electricity.
Heisenberg, a German theoretical physicist, made essential contributions to quantum mechanics. Carl Sagan was an American astronomer, well known for being a science communicator and for making space and natural sciences popular.
Brian Cox, the youngest in this group (born in 1968) is a particle physicist who works on the ATLAS experiment at the Large Hadron Collider, CERN, near Geneva.
I have not written anything about Stephen Hawking or Marie Curie, but you know all about them, don't you?
