The Hunt for Vulcan: . . . And How Albert Einstein Destroyed a Planet, Discovered Relativity, and Deciphered the Universe – Thomas Levenson

TheHuntforVulcanIn the centuries following Sir Isaac Newton’s publication of the Law of Gravity, scientists equipped with increasingly advanced telescopes tried worked to explain anomalies in the orbital paths of planets. “Wobbles” in the orbit of Uranus led to the discovery of Neptune. Mercury also wobbles, and it was long thought that it was under the influence of a small undiscovered planet named Vulcan. This book traces the history of the search for Vulcan, and how Einstein’s Theory of Relativity finally “killed” the need for the little planet.

As history of astronomy and science, this short book is interesting. However it is not page-turning material, failing to really grip the reader.


Raft – Stephen Baxter

Baxter always thinks big, but his stories often revolve around small communities on the edge of the main action in his universe(s). Raft is about such a human community living in a universe where gravity is much stronger than in our universe. The ancestors of the community somehow crossed over into this universe about five hundred years prior to the action. It is a solid story of courage and determination, and the need to face one’s destiny.
