Book review – Other Minds: The Octopus and the Evolution of Intelligent Life

6-minute read

Peter Godfrey-Smith is popularly known as the scuba-diving philosopher and has just published his new book Metazoa, in which he plumbs the evolutionary origins of minds. In preparation for reviewing that book, I am (finally) turning my attention to his initial 2016 bestseller Other Minds. Here he beholds the octopus, only to find that, behind those eight tentacles, an intelligence quite unlike ours beholds him in turn.

Book review – Finding our Place in the Universe: How We Discovered Laniakea – the Milky Way’s Home

6-minute read

The images that astronomers produce can shape whole generations. Based on the Pale Blue Dot photo taken by the Voyager 1 space probe, Carl Sagan’s moving speech in Cosmos highlighted how small and insignificant we appear in the vastness of the universe. But we are not alone, being part of the solar system which is part of the Milky way galaxy. And ours is but one of billions, possibly trillions, of galaxies in the universe that, interestingly, are not scattered at random in space. In this compact and engagingly written book, French cosmographer Hélène Courtois shows you the next level up: superclusters. When it was published in 2014, the image of the supercluster to which our galaxy belongs for me was another one of those generation-defining images. It was of such stunning beauty that it stopped me in my tracks. Welcome to Laniakea, our home amidst the stars.

Book review – Luminous Creatures: The History and Science of Light Production in Living Organisms

Beetles do it. As do fish. And squid, sharks, jellyfish, salps, dinoflagellates, and a host of other invertebrates. Bioluminescence, the production of light by living organisms, is one of nature’s most awe-inspiring spectacles and has fascinated humans since time immemorial. Luminous Creatures, written by bioluminescence researcher Michel Anctil, is a chunky book that charts the history of scientific research on this phenomenon by examining the lives and achievements of many of the key players involved. Along the way, it lifts the lid on many of the wondrous details of bioluminescence.
