where did the rule of 72 come from
Rule of 72 An early reference to the rule is in the Summa de arithmetica (Venice, 1494. Fol. 181, n. 44) of Luca Pacioli (1445â€“1514). He presents the rule in a discussion regarding the estimation of the doubling time of an investment, but does not derive or explain the rule, and it is thus assumed that the rule predates Pacioli by some time.
Seventh Amendment to the United States Constitution The Seventh Amendment is generally considered one of the more straightforward amendments of the Bill of Rights. While the Seventh Amendment's provision for jury trials in civil cases has never been incorporated (i.e., applied to the states) almost every state voluntarily complies with this requirement. The prohibition of overturning a jury's findings of fact applies to federal cases, state cases involving federal law, and to review of state cases by federal courts.[1] United States v. Wonson (1812) established the historical test, which interpreted the amendment as relying on English common law to determine whether a jury trial was necessary in a civil suit. The amendment thus does not guarantee trial by jury in cases under maritime law, in lawsuits against the government itself, and for many parts of patent claims. In all other cases, the jury can be waived by consent of the parties.
