What We Are Reading Today: Wise Gals by Nathalia Holt

Nathalia Holt’s “Wise Gals” tells the story of a small cadre of influential female spies in the precarious early days of the CIA. The women helped create the template for cutting-edge espionage in the post-Second World War era.

The four agents, Adelaide Hawkins, Mary Hutchison, Eloise Page and Elizabeth Sudmeier, were able to make real change in a traditionally “male, pale and Yale” organization — but not without some tragic losses and real heartache along the way.

They were smart, courageous, and groundbreaking agents at the top of their class, instrumental in both developing innovative tools for intelligence gathering — and insisting that they receive the credit and pay their expertise deserved.

What We Are Reading Today: ‘An Introduction to General Relativity and Cosmology’ by Steven A. Balbus

General relativity has entered a new phase of its development as technical advances have led to the direct detection of gravitational radiation from the merging of single pairs of stellar-sized black holes.

The exquisite sensitivity of pulsar signal timing measurements has also been exploited to reveal the presence of a background of gravitational waves, most likely arising from the mergers of supermassive black holes thought to be present at the center of most galaxies.

This book demonstrates how general relativity is central to understanding these and other observations.
