Book review – Mammalian Paleoecology: Using the Past to Study the Present

7-minute read

Scottish geologist Charles Lyell quipped that the present is the key to the past. To say that the reverse also holds is more than just circular reasoning. Felisa Smith, a professor in ecology and evolutionary biology, studies extinct mammals and applies this knowledge to the present. This book is a neatly crafted package that gives the reader all the required background knowledge, while its case studies make for fascinating reading. (Spoiler alert: packrat middens are my new favourite discovery.)

Book review – Growth: From Microorganisms to Megacities

8-minute read

Growth as a process is ubiquitous. It is the hallmark of every living organism. It motivates much of what we as humans do, as often unspoken as it is outspoken. It is the narrative lens through which we examine societies and civilizations past and present. And it is the altar at which economists worship. You would think that nobody in their right mind would write a book that tries to encompass all of the above. Leave it to a deep thinker such as Vaclav Smil to prove to you otherwise.

Book review – How to Walk on Water and Climb up Walls: Animal Movement and the Robots of the Future

Animals move in many different ways – hopping, gliding, flying, slithering, walking, swimming, etc. their way through our world. Studying how they do this brings together biologists, engineers, and physicists in disciplines such as biomechanics, bioengineering and robotics. Author David L. Hu, for example, is a professor of mechanical engineering and biology. How to Walk on Water and Climb up Walls is a light and amusing romp through the many remarkable forms of animal locomotion, and the equally remarkable experiments that are informing the robots of the future, although it leaves out some notable examples.

Book review – The Equations of Life: The Hidden Rules Shaping Evolution

Starting your book blurb by asking why gazelles have legs rather than wheels is a suitably out-there question to immediately grab a reader’s attention. A more pertinent question then; why is all life based on carbon rather than silicon? In The Equations of Life, Charles Cockell takes the reader on a giddy tour down the organisational hierarchy of life – from sociobiology to subatomic particles – to show that nature is far more predictable and understandable than it might appear at first blush. His eloquent answer to above and other why questions? “Because physics is life’s silent commander”.

Book review – Spying on Whales: The Past, Present and Future of the World’s Largest Animals

It should have been a straightforward expedition. As a young career palaeontologist, Nick Pyenson found himself in the Atacama desert of Chile, tasked with mapping rock layers to establish a continuous chronology that would help dating fossils found in the area. Whale fossils, Pyenson’s speciality, are rarely found complete, which is true of most fossils. So what do you do when a colleague takes you to the construction site of a new highway and shows you not one, not several, but literally dozens of complete fossil whale skeletons? It represented a treasure trove for science, but retrieving the material before the highway constructors would move in was also a daunting, labour-intensive task that could make or break careers. I almost found myself standing next to Pyenson in the dusty clearing, the Chilean sun beating down on me as he faced this dilemma. This is just one of several immersive narratives recounted in Spying on Whales, which successfully blends travelogue and popular science.

Book review – Scale: The Universal Laws of Life and Death in Organisms, Cities and Companies

Not since I had to read D’Arcy Wentworth’s On Growth and Form for coursework have I read such a fascinating book that highlights the importance of mathematical laws in governing boundaries and patterns we observe in life. Geoffrey West is a polymath in the truest sense of the word: a theoretical physicist who, over the course of 20 years, applied complexity science to many questions in biology initially, and then extended his ideas to patterns seen in the organization and functioning of cities and companies. Scale is a wide-ranging intellectual foray with no equation in sight.
