Pedantic. When people say micro-scale/nano-scale they mean “measured in micrometers/nanometers”. So a nanoparticle is a particle with a size that makes nanometers the most convenient unit.

Nobody who has used linux ever makes memes like this. Nobody who has had enough experiences with windows does either.

I like how whenever there’s a pedantic viral math “problem” half of the replies are just worshiping one answer blindly because that’s how their school happened to teach it.

I’m not too good at math but i think it’s because the set of integers is defined as the set that contains all natural numbers and their opposites, while the set of natural numbers is defined using the successor function - 0 (or 1) is a natural number; if a number n natural, then S(n) is natural where S(n) = n+1.

Because a number isn’t just a representation of a size or amount - that’s called a scalar. A number can also represent a point in a space, the label of a vertex on a graph and probably some other things too.
