• What are the ways to correct typos and grammatical errors in RG questions?
• What are the ways to reduce the number of question marks in a question?

The answer to both the above questions can be found in the Edit arrow close to the top right of your question. See attached.

The only thing 'nano' in the word 'nano' is the implication of 10-9 and thus some measure of size should be obligatory. Unless, of course, we're talking of nanomoles, nanodrops, nanoseconds etc where the term 10-9 is important but where size may not be.

How can you measure what you can’t see?

The Rayleigh criterion is probably the biggest obstacle.
