That baffled me for a minute until looking at it. I had forgotten that slide rules
could be circular. Sure beats for size the large German-made one inherited
from my engineer brother that I carted around in the early 50's at University.
It was too big to fit properly in my zipper binder. I eventually bought a
cheaper one that was only 10-12" long. I was aghast when much later my
son was allowed to bring an electronic calculator with him into exams.
IIRC slide rules were strictly verbotten in my time.
