SIZE: How it Explains the World | Vaclav Smil, William Morrow Publishing (2023), 304p.

​In "Size: How It Explains the World," author Vaclav Smil embarks on an intriguing journey to explore the significance of scale in various aspects of our lives. From the nanoscale to the global level, this book delves into the impact of size on biology, technology, society, and the environment. As an energy and environmental science expert, Smil brings his unique perspective to reveal the profound effects of scaling on our world.

The book begins with an introduction to the concept of scale and its importance in understanding various phenomena. Smil effectively illustrates how size influences everything from materials’ strength to transportation systems’ efficiency. He presents fascinating examples, such as the fact that spider silk’s strength-to-weight ratio is more significant than steel’s, highlighting the remarkable properties of natural materials.

One of the most compelling aspects of the book is its examination of the role of size in biology. Smil discusses the evolution of species, explaining how their size affects their survival, reproduction, and interactions within ecosystems. He also explores the implications of size in human health, demonstrating how body mass index (BMI) can mislead us in assessing health risks. These insights offer readers a fresh perspective on the interconnectedness of life and the importance of considering scale in scientific research.

Smil's discussion of technology is equally captivating as he investigates the limitations and potential of various inventions. He analyzes the constraints size imposes on engineering feats such as bridges, buildings, and aircraft and the challenges faced in miniaturizing electronic devices. His explanations of the physics behind these concepts are accessible and engaging, making them enjoyable for experts and non-experts alike.

The section on social and economic issues is particularly thought-provoking. Smil sheds light on topics like urbanization, population growth, and global trade, emphasizing the significance of scale in addressing these challenges. He argues that understanding the relationship between size and complexity is essential for effective decision-making in politics and business.

Throughout the book, Smil presents numerous graphs and diagrams to support his arguments. While they are generally helpful in illustrating key concepts, some may need to be more complex or dense for casual readers. However, this minor flaw does little to detract from the overall value of the text.

"Size: How It Explains the World" is a stimulating and informative read offering a new perspective on the world. Vaclav Smil's extensive knowledge and engaging writing style make this book appealing to a broad audience interested in science, technology, and sustainability. By examining the impact of scale on various domains, Smil encourages readers to think critically about the consequences of size in our daily lives and inspires us to consider innovative solutions to our challenges.
