China and Greece present an ideal example of cooperation

In my primary school days, I had a contest with fellow classmates over how many digits we can remember of the mathematical constant pi (π), the ratio of a circle's circumference to its diameter. It is a creation of Greek mathematician Archimedes around 250 BC.

So it was no surprise that I quickly bought a T-shirt with a huge (π) sign, along with 100 decimal digits, when I saw it in a shop in the picturesque Plaka neighborhood in Athens during my first trip to Greece.

Archimedes is one of the many mathematicians, physicists and philosophers of the ancient Greek civilization who has fascinated not only Chinese, but the whole world.
