MathDL News

Until further notice, MAA Reviews and Classroom Capsules and Notes are accessible to everyone without any restriction. Now is a great time to see what those sites have to offer.

In Loci: Convergence read the new articles:

Combining Strands of Many Colors: Episodes from Medieval Islam for the Mathematics Classroom by Randy Schwartz. This article includes 5 classroom modules for elementary stats, finite math, calculus, and linear algebra.
Logarithms: The Early History of a Familiar Function by Kathleen Clark and Clemency Montelle. The authors present and explore the work of both Napier and Burgi. The article includes photos of Burgi’s rarely seen handwritten and printed work.
A Disquisition on the Square Root of Three by Robert Wisner, in which the author compares Greek ladder, continued fraction, and Newton’s Method estimates, and notes that the Greek ladder easily gives both of Archimedes’ famous bounds.

Also take a look at the companion articles:

Servois' 1814 Essay on the Principles of the Differential Calculus, with an English Translation by Robert E. Bradley and Salvatore J. Petrilli, Jr., discusses the revolutionary notions of differential calculus in a revolutionary world as held by François-Joseph Servois (1768-1847). The article contains an English translation of the paper "Reflections" by Servois.
François-Joseph Servois: Priest, Artillery Officer, and Professor of Mathematics by Salvatore Petrilli.
