E121 -- Opuscula Varii Argumenti, Bd. 2
(Various works, volume 2)
Originally published with the full title:
Conjectura physica circa propagationem soni ac luminis una cum aliis
dissertationibus analyticis
De numeris amicabilibus De natura aequationum, ac De rectificatione ellipsis.
(Physical conjectures on the propogation of sound and light with other dissertations:
on amicable numbers, on natural equations, and on the rectification of ellipses)
Summary:
E121 is one of an unusual group of Enestrom numbers. It refers to a collection of articles
which were published together (in this case E151-E154), but which contains no other
writings of Euler.
According to Enestrom, E121 is usually referred to as Opuscula Varii Argumenti, volume 2, as it part of a three
volume series. The other two parts are:
