[ Measuring with Yen ]

This problem was originated by Mitsunobu Matsuyama, a reader in Tokyo. He sent me a supply of Japanese one-yen coins and told me
of the following remarkable facts about them that are not well known
even in Japan.

The one-yen coin is made of pure aluminum, has a
radius of exactly one centimeter, and weighs just one gram.

Thus a supply of yens can be used with a balance scale for determining the
weight of small objects in grams. It also can be used on a plane surface
for measuring distances in centimeters.

It's certainly awkward when used of a "problem". "First mentioned"?

You can originate an approach, so an approach can be originated.

[OT] Are the Japanese still using any?
(Yens are worth less than cents, Euro or US)
The one Yen coins are no longer minted, except for collectors,
because the aluminium costs more than the coin is worth. [1]

I guess Martin Gardner could get a supply of used ones,

[1] Eurocents will last another decade, perhaps,
because the are copper-clad iron, which is cheaper.
