Many species nest on buildings, and the House and Eurasian Tree Sparrows in particular inhabit cities in large numbers, so sparrows may be the most familiar of all wild birds.

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

Many traditional regional cuisines rely on basic methods of preservation such as drying, salting, pickling and fermentation.

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.
