The Mathematics and the Liberal Arts pages are intended to be a resource for student research projects and for teachers interested in using the history of mathematics in their courses. Many pages focus on ethnomathematics and in the connections between mathematics and other disciplines. The notes in these pages are intended as much to evoke ideas as to indicate what the books and articles are about. They are not intended as reviews. However, some items have been reviewed in Mathematical Reviews, published by The American Mathematical Society. When the mathematical review (MR) number and reviewer are known to the author of these pages, they are given as part of the bibliographic citation. Subscribing institutions can access the more recent MR reviews online through MathSciNet.
Evans, Brian. Number and form and content: a composer's path of inquiry. The Visual Mind, 113--120, Leonardo Book Series, MIT Press, Cambridge, Mass., 1993.
The author shows how the golden ratio occurs in music and art. His examples include Mozart's Symphony in G Minor, Grant Wood's American Gothic, Piet Mondrian's Composition with Blue, and some of his own musical and visual compositions. More controversial examples include the Great Pyramid in Egypt and Stonehenge, where the author shows how approximate values of both pi and the golden ratio can be found. The author mentions Luca Pacioli's statements on the golden ratio in De Divina Proportione and discusses other aspects of the philosophy of number and art as well.

Neugebauer, O. On the orientation of pyramids. Special issue dedicated to Olaf Pedersen on his sixtieth birthday. Centaurus 24 (1980), 1--3. (Reviewer: H. W. Guggenheimer.) SC: 01A15, MR: 81k:01004.
Neugebauer gives a theory that explains how the Egyptians could have oriented their pyramids without using the advanced astronomical knowledge sometimes attributed to them. The theory relies on the construction of an accurately shaped pyramidal model (for example the capstone of the future pyramid), and on watching the shadow of the model in the course of the day. The biggest question about this procedure may be the question of how the model can be made accurately enough. Nevertheless, this theory represents a great simplification over many other theories.

Martin Bernal's Black Athena created a bit of a sensation when it first came out. Robert Palter discusses aspects of Bernal's article and also other arguments of afro-centrists. Palter particularly focuses on the question of whether Egyptian mathematics and science influenced the Greeks. Bernal suggests that the influence may be quite large, and Palter argues that all existing evidence points to the influence being quite small. An important area in Palter's discussions is ancient astronomy, where Palter discusses the general character of Egyptian astronomy, and argues that some claims about it have been vastly exaggerated; much of this discussion focuses on discrediting claims made by John Pappademos. Palter then notes that Peter Tompkins, author of Secrets of the Great Pyramid, seems to suggest that Newton was led by Egyptian science to discover his law of gravitation. About Tompkins, Bernal writes that "it it a tragedy that Tompkins's brilliant and scholarly book has been stripped of its scholarly apparatus". Palter writes "It seems never to have occurred to Bernal that the absence of scholarly apparatus in Tompkins's account of Newton has a very simple explanation: no scholarly evidence exists to support that account." When discussing Egyptian mathematics proper, Palter focuses discusses the general character, and then square roots (or a relative lack of them), the value of pi, the controversial problem in the Moscow papyrus on the surface area of a basket, the Pythagorean theorem (or the relative lack of it, arguments on the special case of involving the diagonal of the square), and the notion (or absence of notion) of an irrational number. Palter attacks claims by Cheikh Anta Diop (see Civilization or barbarism: An authentic anthropology) that Archimedes stole some of his most famous mathematics from the Egyptians. Palter then discusses pyramidology, and some of the claims cited by Bernal that "one can find such relations as pi, phi, the 'golden number' and Pythagoras' triangle from them." The final section, discusses the similarities and differences between Egyptian and Greek medicine. Although Mathematics is not so directly involved here, strong Egyptian influence in Greek medicine could argue for the plausibility of influence of other Egyptian science on Greek science as well. A very interesting paper. Apart from the fact that Palter's article serves as a kind of review of Bernal's book, it is worth reading for its discussions on the nature of Egyptian mathematics and science. Bernal responds to Palter's article in Bernal, Martin, Response to a paper by R. Palter: "Black Athena, Afro-centrism, and the history of science" [Hist. Sci. 31 (1993), no. 93, part 3, 227--287; MR: 94i:01001]. Closely related topics: Ancient Egypt, Greece, Astronomy, Archimedes, Pythagorean Triangles and Triples, and Medicine.
Robins, Gay and Shute, Charles C. D. Mathematical bases of ancient Egyptian architecture and graphic art. Historia Math. 12 (1985), no. 2, 107--122. (Reviewer: Jens Høyrup.) SC: 01A15, MR: 87c:01002.
The authors discuss the slopes that occur in Egyptian pyramids and artwork. The discussion of Egyptian artwork is particularly interesting because of the Egyptian's conscious use of squared grids. The authors find no evidence of circles or the value of pi being used in to determine the overall dimensions of the pyramids, and similarly with the golden ratio. Similarly, the authors find no evidence of pi or the golden ratio being found in slopes of lines in Egyptian artwork. Nevertheless, the authors carefully discuss such claims rather than simply dismissing them out of hand. The authors do, however, find that certain "slopes" seem to have been preferred to others (as the authors note, the Egyptians seem to have preferred to measure slopes as run per unit rise rather than our rise per unit run). The authors buttress their arguments about the artwork through their use of new photographs; these carefully avoid distortion by means of a shift lens. The article is only moderately technical.
