What We Are Reading Today: Sierra Leone; A Political History

Author: David Harris

Sierra Leone came to world attention in the 1990s when a catastrophic civil war linked to the diamond trade was reported globally. 

The book examines the history and independence of the African nation, placing state-society relations at the centre of an original and revealing investigation of those who have tried to rule or change the country and its inhabitants and the responses engendered. 

It interweaves the historical narrative with sketches of politicians, anecdotes, the landscape and environment and key turning points, alongside theoretical and other comparisons with the rest of Africa. 

It is a new contribution to the debate for those who already know Sierra Leone and a solid point of entry for those who wish to know.

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.
