What We Are Reading Today: In Pursuit of Zeta-3

Author: Paul J. Nahin 

For centuries, mathematicians the world over have tried, and failed, to solve the zeta-3 problem.

Math genius Leonhard Euler attempted it in the 1700s and came up short.

The straightforward puzzle considers if there exists a simple symbolic formula for the following: 1+(1/2)^3+(1/3)^3+(1/4)^3+… . But why is this issue — the sum of the reciprocals of the positive integers cubed—so important?

With “In Pursuit of Zeta-3,” popular math writer Paul Nahin investigates the history and significance of this mathematical conundrum.

What We Are Reading Today: Invisible Hands by Margaret S. Graves

In the heyday of Islamic art collecting around the turn of the 20th century, thousands of premodern ceramic objects circulated on the international antiquities market. 

“Invisible Hands” tells the story of how traditional craft skills of the Islamic world, often thought to have died out with the advent of industrialization, were redirected toward a thriving new market in the colonial era: the fabrication and fictionalizing of antiquities, especially ceramics.

In this stunning work of art history, Margaret Graves shakes the foundations of the discipline, challenging us to reconsider what is and is not art.
