Problem: The target audience of natural history was French polite society, evidenced more by the specific discourse of the genre than by the generally high prices of its works. Naturalists catered to polite society's desire for erudition many texts had an explicit instructive purpose. However, natural history was often a political affair. As E. C. Spary writes, the classifications used by naturalists "slipped between the natural world and the social ... to establish not only the expertise of the naturalists over the natural, but also the dominance of the natural over the social". The idea of taste (le gout) was a social indicator: to truly be able to categorize nature, one had to have the proper taste, an ability of discretion shared by all members of polite society. In this way natural history spread many of the scientific developments of the time, but also provided a new source of legitimacy for the dominant class. From this basis, naturalists could then develop their own social ideals based on their scientific works.

Problem: Lossless data compression algorithms usually exploit statistical redundancy to represent data without losing any information, so that the process is reversible. Lossless compression is possible because most real-world data exhibits statistical redundancy. For example, an image may have areas of colour that do not change over several pixels; instead of coding "red pixel, red pixel, ..." the data may be encoded as "279 red pixels". This is a basic example of run-length encoding; there are many schemes to reduce file size by eliminating redundancy.
What is possible because most real-world data have areas of color?

Problem: Most of the space in the brain is taken up by axons, which are often bundled together in what are called nerve fiber tracts. A myelinated axon is wrapped in a fatty insulating sheath of myelin, which serves to greatly increase the speed of signal propagation. (There are also unmyelinated axons). Myelin is white, making parts of the brain filled exclusively with nerve fibers appear as light-colored white matter, in contrast to the darker-colored grey matter that marks areas with high densities of neuron cell bodies.
Myelin is what color in the brain?
