OK. _Are_ infinitesimals actually _defined_ in standard mathematics?
And if so, could you please tell me how?

Oddly enough, the treatment of calculus by rigorous notion of
infinitesimals is called 'nonstandard analysis', so I guess the answer
would strictly be 'no'.

Oddly enough Han does not like that either.

Perhaps it wasn't formulated by engineers? He seems to share a common
mindset for physicists/engineers that mathematicians are somehow
"enemies" or "annoying formalists" that contribute nothing and just
ruin things.
