 63 years ago today marked the United States' entrance into World War II.
Axis and Allied powers delineated foes and friends, respectively. This week's engineering crossword has as its theme Axis and Allied
powers - all of whom are global trading partners nowadays. The 'Allied' powers term is clear enough, but where does the 'Axis' powers term originate?
Merriam-Webster answers that in its 9th - and last, therefore least
used - definition: "a point or continuum on which something centers <an axis of social power>."
