Can I hold it? Only if you promise to be really, really careful.

I promise I will be so incredibly careful. I will be incredibly careful with it. I promise. So, it's slippery, be careful. Alright, are we ready?

I'm about to touch a 1kg sphere of silicon-28 atoms. There are about 2.15x10^25 of them. It feels absolutely incredible. Wow, that is amazing.

Besides its creators, I am one of only a handful of people ever to hold this sphere. The raw material used to make it was worth 1 million Euros but now that it has been so

precisely sculpted -- How much is that worth?

It's priceless. ... This you are looking at now is the roundest object in the world. How can you say for sure it's the roundest object? I mean the Earth is pretty round,

isn't it? If this was the Earth... If this were the Earth then the highest mountain to the lowest valley would be... about 14m

apart. That is shocking. That is shockingly round.

But why would you invest one million Euros and thousands of man-hours perfecting a pure, polished silicon sphere?

Well the answer is grave. Or rather 'grave' as it would have been pronounced in the original French.
