Can somebody provide an intuitive example of how small a micron is? (No maths please).

one millionth of a metre.
And in real terms a spiders web strand is 5-10 Microns thick

Yes really.
But it is when you start getting down to Angstroms things start to get pretty small!

They can be measured Abacus. Not with a ruler though, even if you have decent specs!

Not a term I am familiar with Abacus, but what about a planck length divided by two?
A bit like infinity I would have thought - just add one.
By the way, the special film on Fireman's visors? Around 50 Angstroms thick. The film on two way mirrors?, between 50 and 150 Angstroms, so it does have a practical side.

From what I can gather a Planck length is the smallest possible distance that can be conceptualized in terms of what is known about the physical universe. By that I mean the known laws that have been established over the past hundred years or so such a the speed of light, atomic structure and so on. It is possible to talk of smaller distances but so far has no reality in what is considered as the physical universe. Great, those kinds of examples are far more helpful in trying visualize what an Angstrom is.

Abacus.
I thought the smalest measurement was not a planck but a gnats tadger?
