Book review – Lithium: The Global Race for Battery Dominance and the New Energy Revolution

7-minute read

This is the second of a two-part review on the batteries that are powering electric vehicles (EVs).

When seeing the world through a deep-time lens, no landscape feature is permanent. The Sahara, for example, “only” came into existence some 7 million years ago. In that time, it has not always been the parched desert it is now but has been green and verdant numerous times, crisscrossed by rivers and home to hippos, turtles, fish and other animals and plants typical of wetter climes.

Book review – Weird Earth: Debunking Strange Ideas about Our Planet

7-minute read

Geologist and palaeontologist Donald R. Prothero is a busy man. Next to writing a steady stream of books on geology, fossils, and evolution, he is a noted sceptic.

In Weird Earth, Prothero debunks conspiracy theories and pseudoscience relating to our planet, making for an entertaining slaying of geological fringe ideas. However, his aim is not merely to demean, but also to show readers what the actual evidence is and how we gather it. If the idea of a flat earth strikes you as unbelievable, buckle up, because it gets much weirder.
