Archaeologists agree that corn agriculture, first developed by Native American peoples of what is now Mexico, was adopted by Native Americans of what is now the southwestern United States during the Late Archaic period, but the extent of these Late Archaic peoples' dependence on corn agriculture is debated. Some archaeologists infer from the presence of houses storage pits, and large quantities of corn kernels at Late Archaic sites that the inhabitants, once nomadic hunter gatherers, had become settled farmers who, although they lacked the ceramic vessel-making technology typically associated with agriculture, grew and depended on corn. But other evidence strongly suggests that while Late Archaic people grew considerable quantities of corn, it was not their dietary mainstay. Food-processing equipment found at the sites indicates that Late Archaic people continued to rely heavily on wild plant foods. Corn is not a particularly nutritious food. People whose diets are heavily dependent on corn today soak it in limewater and grind it to prepare mush, processes that increase corn's nutritional value; these steps would have been difficult to accomplish without ceramic vessels.

In his history of algebra, John Derbyshire asserts that when Descartes chose the letter X to represent the principal unknown, he did so for the printer' s convenience, because X is used less often in French than Y or Z. In fact, according to cryptography texts, X is used more often than Y in French. Derbyshire's source for his assertion is Classic Math, whose author, Art Johnson, gives no footnote for the claim but who may have misunderstood a conjecture made in 1905 - almost 300 years after Descartes - by Gustav Eneström and mentioned in a book included in Johnson' s Bibliography. Eneström supposed that X was chosen because it occurs more often than Y and Z, and printers therefore would have had more X's available.

The fact that certain musical qualities were shared by African American and White jazz musicians in the mid-1950s was sometimes explained by claiming that jazz was "color-blind." Yet a look at how the discourse of color blindness was deployed in 1950s jazz periodicals helps explain why many African American jazz musicians began to emphasize differences, rather than similarities, between the aesthetic styles of Black and White Musicians. The discourse of “color blindness" tended to exaggerate the permeability of racial boundaries by failing to address the power relationships involved in a social climate where evasiveness about race was often used to silence African American perspectives on the meaning of jazz. While the expression of color-blind sentiments was not necessarily disingenuous, structural racial stratification remained powerful beyond the bandstand.

It's hard to envision jazz flourishing without Thomas Edison' s roughly contemporaneous invention of sound recording technology, which enabled the preservation and dissemination of the genre's hallmark musical improvisations for the first time in history. But the same technology also significantly altered jazz's evolution. Before the rise of jazz, African American composers worked extensively with more complex forms. Most of Scott Joplin's ragtime pieces included four sections, each with a distinctive melody and chords, and many early jazz musicians continued in this vein. But early recordings, which limited songs to three minutes, could rarely accommodate such structures and still leave time for improvised solos. With a few exceptions, such as Duke Ellington, most jazz musicians embraced simpler tunes once they began recording their work.
