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.
Ellerman, David P. The mathematics of double entry bookkeeping. Math. Mag. 58 (1985), no. 4, 226--233. (Reviewer: D. J. Struik.) SC: 90C99 (01A99 20G99), MR: 87a:90151.
The double entry bookkeeping system was first described by Luca Pacioli in 1494, though it had been developed in the 1300s. One feature of the system is that it in effect constructs the negative numbers Z from the natural numbers omega. This same construction is regularly done as well in courses in logic and set theory and may also be relevant to courses on the foundations of our number system (e.g., for those planning to teach elementary school students).

Emmer, Michele. Art and mathematics: the Platonic solids. The Visual Mind, 215--220, Leonardo Book Series, MIT Press, Cambridge, Mass., 1993.
The author begins by mentioning some ancient representations of Platonic solids. These include a pair of Egyptian die from the Ptolemaic dynasty, an Etruscan dodecahedron (at least 2500 years old), two Celtic dodecahedra, and a West German dodecahedron from the 2nd century BC. The author continues with a discussion of the regular solids in Plato's Timaeus. The author notes that Dürer's Melancholia, which includes a truncated rhombohedron, is sometimes thought to show the influence of Luca Pacioli. The magic square in the painting gives some evidence for this; Dürer's engraving may be one of the earliest depictions of a magic squares in the West, but an earlier manuscript by Pacioli showed an interest in them. On the other hand, Luca Pacioli's De Divina Proportione relied heavily on, and perhaps even appropriated the work of Piero della Francesca. The book is also notable for its pictures of the regular solids, attributed to Leonardo da Vinci. Also discusses work on the regular solids due to Johannes Kepler, including Kepler's recognition of a duality and his idea of a combination of two tetrahedra called a stella octangula. The author notes that the notion of the stella octangula also appears in Pacioli's De Divina Proportione. In addition, Kepler's stellated dodecahedron occurs in mosaics in the San Macro Cathedral in Venice; this work is thought to have been done by Paolo Uccello. Regarding Uccello, the author quotes Donatello as saying to his close friend "Ah Paolo, this perspective of yours makes you neglect what we know for what we don't know. These things are no use except for marquetry." (The source is Vasari's Vita di Paolo Uccello.) The author, Michele Emmer, collaborated on the film Art and Mathematics.

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. Closely related topics: Proportion and the Golden Ratio, Music, Art, Wolfgang Amadeus Mozart (1756-1791), The Egyptian Pyramids, and The Stone Builders.Modify notes on this entry Modify bibliography entry Make comment on this entry
Pressman, Ian and Singmaster, David. The jealous husbands and the missionaries and cannibals. Math. Gaz. 73 (1989), no. 464, 73--81. (Reviewer: E. Keith Lloyd.) SC: 01A99 (05A99), MR: 92b:01086.
There are three river crossing problems in the Propositiones ad Acuendos, which is generally attributed to Alcuin: the problem of three jealous husbands (each of whom won't let another man be alone with his wife), the problem of the wolf, goat, and cabbage, and the problem of "the two adults and two children where the children weigh half as much as the adults." The authors discusses modifications of these problems and attempted solutions by Luca Pacioli, Tartaglia, and others. Modifications include the addition of more people, an island in the center, and a bigger boat. A more recent version is the problem of the Missionaries and the Cannibals, where the cannibals must never outnumber the missionaries. The authors give some solutions and theorems on minimality, although they leave their discovery of a 16 move solution to the four-couples-with-an-island problem as "a nice exercise for the reader". The authors don't discuss this, but problems similar to the wolf-goat-cabbage problem have appeared in a variety of cultures. Closely related topics: Alcuin, Discrete Mathematics, Niccolò Fontana (Tartaglia) (1499?-1557), and Mathematics in Recreation.Modify notes on this entry Modify bibliography entry Make comment on this entry
