In general, we are not wired correctly to deal with concepts outside of our immediate neighborhood.

You can say with confidence that there are 3 people in a room. Or about 20. Or roughly 100-200-300. Or a lot. A stadium filled with 10,000 people is not different from one filled with 100,000 people - for someone who sees them for the first time.

A million times bigger does not mean anything. What is a hair x 1M? No idea.

I am an ex-physicist and I leaned to just look at the numbers and compare them when needed. 10^-18 is fine for something because I learned that but I cannot imagine it. Same for 10^23.

This is also the reason why homeopathy does not sound bad to people when it is written 100 CH on the bottle. 100 looks good. It is a 10^-100 dilution ratio.
