An Engineer in Wonderland – Thinner than a human hair
Blah blah blah is 1,000 times thinner than a human hair.
My human hair visualisation is already wobbling at half as thick as a human hair.
And why emphasise human?
And what colour human hair? – as fine blond human hair is about one tenth the thickness of course black human hair.
So, after a bit of thinking, I propose a new metric:
How many of [interesting things] would fit on the edge a razor blade.
Roughly, a human hair is 100µm in diameter, and a nice new razor blade edge is 0.4µm across, which I am approximating to 0.5µm when it has been used a bit.
Although you cannot visualise the edge of a razor (well, a few experts can) we all know that it is pretty thin.
So, a razor blade edge is 200 times thinner than a human hair – gaining two orders of magnitude.
Five state-of-the-art transistor gates would fit on the edge of a razor blade – which is amazing in itself – and easier to think of than 1,000 times thinner than a human hair.
I rest my case
