Many years later ( on August 3, 1915 ), Lucy Upton wrote Winslow's daughter soon to be graduated from Smith College: `` While I love botany which, after dabbling in for years, I studied according to the methods of that day exactly forty years ago in a summer school, it must be fascinating to take up zoology in the way you are doing.

Many such short processes involve a few changes to traditional methods, including smaller, more homogenized pieces in the compost, controlling carbon to nitrogen ( CN ) ratio at 30 to 1 or less, and monitoring the moisture level more carefully.

Many types of calculations ( known as post-Hartree – Fock methods ) begin with a Hartree – Fock calculation and subsequently correct for electron – electron repulsion, referred to also as electronic correlation.

Many classes have methods that call their own functions, thereby looking and feeling like most other OO languages.

Many countries have growing electoral reform movements, which advocate systems such as approval voting, single transferable vote, instant runoff voting or a Condorcet method ; these methods are also gaining popularity for lesser elections in some countries where more important elections still use more traditional counting methods.

Many modern moorings still rely on a large rock as the primary element of their design.

Many platforms rely on emulation, the simulation of an older platform in software, to achieve backward compatibility.

Many important forest functions have no markets, and hence, no economic value that is readily apparent to the forests ' owners or the communities that rely on forests for their well-being.

Many divers rely on their coaches to help keep their composure during the meet.

Many algorithms for computing Delaunay triangulations rely on fast operations for detecting when a point is within a triangle's circumcircle and an efficient data structure for storing triangles and edges.

* Many other forms of spectroscopy also rely upon Fourier Transforms to determine the three-dimensional structure and / or identity of the sample being analyzed, including Infrared and Nuclear Magnetic Resonance spectroscopies.

Many arguments involving finite sets rely on the pigeonhole principle, which states that there cannot exist an injective function from a larger finite set to a smaller finite set.

Many treaties ( such as the North American Free Trade Agreement, or the General Agreement on Tariffs and Trade before the establishment of the World Trade Organization ) do not establish an organization and instead rely purely on the parties for their administration becoming legally recognized as an ad hoc commission.

Many CD authoring applications attempt to get around the filename length by truncating filenames automatically, but do so at the risk of breaking applications that rely on a specific file structure.

Many congregations, especially larger ones, also rely on a:
