If you've ever felt you've been followed by some colours, numbers, names, phrases, you know exactly what I mean. These days, I've been under the constant impression that Plato is after me. Yes, Plato (which, surprisingly, is not my guinea pig). How have I reached this outrageous conclusion? Well, my best friend recommended me a book called The Plato Papers, by Peter Ackroyd ( do read it, it's magnificently unexpected). So right now, it's stalking me from my night stand, begging for a bit of my time. And yesterday, my frantic web browsing led me to buckminsterfullerene (for friends, bucky). And what do you know, it's somehow connected to Plato ( and no, the scientist that discovered it was not named Buckminster). The shape of bucky (for scientists, C60 and also a hollow sphere composed of carbon atoms) is that of a geodesic dome (resembling the structures built by Richard Buckminster Fuller). Although some of you might expect a geographical globe with a daisy on top, it is a structure based on what are usually called the Platonic solids (don't worry, I completely ignored their existence until now as well). The fancifully named bodies above are actually regular polyhedra (amongst them, the cube and other well-known acquaintances).
As the world is the small, viruses are also linked to Plato (I'm sure Plato wouldn't have liked that): the shape of some viruses resembles that of some Platonic bodies. But about viruses, and how they make their beautiful envelopes, in a future post.

It's just a matter of simmetry and in space it's actually pretty restricitive. Once I asked my maths teacher: why are there only 5 Platonic Solids and an infinite number of regular polygons? There should be more degrees of freedom when an aditional dimension is added. It was the one question he couldn't answer me. Although the bearded guy next to him could. (a bunch of boring topological equations and Euler's theorem). Well anyway no hidden philosophy there, just the standard lazyness of nature.
