Divisors and Sandpiles: An Introduction to Chip-Firing
Divisors and Sandpiles provides an introduction to the combinatorial theory of chip-firing on finite graphs. Part 1 motivates the study of the discrete Laplacian by introducing the dollar game. The resulting theory of divisors on graphs runs in close parallel to the geometric theory of divisors on Riemann surfaces, and Part 1 culminates in a full exposition of the graph-theoretic Riemann-Roch theorem due to M. Baker and S. Norine. The text leverages the reader's understanding of the discrete story to provide a brief overview of the classical theory of Riemann surfaces. Part 2 focuses on sandpiles, which are toy models of physical systems with dynamics controlled by the discrete Laplacian of ...
The Likeness of the King
Anyone who has strolled through the halls of a museum knows that portraits occupy a central place in the history of art. But did portraits, as such, exist in the medieval era? Stephen Perkinson's "The likeness of the king" challenges the canonical account of the invention of modern portrait practices, offering a case against the tendency of recent scholarship to identify likenesses of historical personages as "the first modern portraits". Focusing on the Valois court of France, he argues that local practice prompted shifts in the late medieval understanding of how images could represent individuals and prompted artists and patrons to deploy likeness in a variety of ways.

Good Morning-- Mr. Featherstone?
Seth Parkinson (b.1634), son of Seth Parkinson, immigrated from England to Henrico County, Virginia before 1677. Seth Perkinson (d.1735), his son, spelled the surname Perkinson, as did later descendants. Descendants lived in Virginia, North Carolina, Tennessee, Georgia and elsewhere. Includes ancestors in England to the early 1200s, showing the Perkinson family as descendants of Elias de Featherstonehaugh (his great-grandson was John le Perkynson, who discarded the surname Featherstonehaugh).
Mathematical Understanding for Secondary Teaching
A perennial discussion about teacher development is the optimal content background for teachers. In recent years, that discussion has taken center stage in the work of mathematics education researchers, mathematicians, mathematics professional developers, and mathematics education policymakers. Much of the existing and prior work in this area has been directed toward mathematical knowledge for teaching at the elementary level. The work described in this volume takes a sometimes-neglected approach, focusing on the dynamic nature of mathematical understanding rather than on a stable description of mathematical knowledge, and on mathematics for secondary teaching rather than mathematics for tea...
Perkinson Kin
Descendants of Seth Perkinson (d. ca. 1780). His will was written 25. August, 1780, probated 1782 in Raleigh Parish, Amelia County, Virgi- nia. He was a son of Seth Perkinson (d. ca. 1731), whose will was probated on April 7, 1735 in Bristol Parish, Henrico Co., Virginia. Seth married (1) Mary, (2) Elizabeth. He had eight children, oldest born in 1727. Descendants live in North Carolina, Virginia, Texas and elsewhere.
