when I click [Kane 1985] , above eq (54) it does not get me to the references as before. It gets me back to the top of the chapter.

Of course, eq (54) is a definition, and not be be argued with.
But, for example, the term:
$\left(\dfrac{{}^Âd\hat b_y }{dt} \circ \hat b_z \right) \hat b_x$ seems to have also an intuitive meaning:
$\dfrac{{}^Âd\hat b_y }{dt} \circ \hat b_z$ is the magnitude of the change of $\hat b_y$ in $\hat b_z$ direction. but this intuitively corresponds to a infinitesimal rotation of B around the $\hat b_x$ axis. This is not very brilliant at all, but is there not some intuitive explanation of (54)? For me, it sort of just 'drops from the sky'. ( I believe we discussed this earlier)

Ichecked my old books on mechanics (all older than 1985), but did not find anything intuitive.

Upon second thought: the abstract definition (54) gives all the more intuitive results as is shown further down in the lecture.
This is probably enough 'justification' for it.

Some things may not work in the preview.

Where further down do you think it shows this?

I think I'll open a separate issue for this, as I won't be able to address it immediately.
