Deb Chachra at Harvard Book Store

Harvard Book Store welcomes DEB CHACHRA—professor at Olin College of Engineering—for a discussion of her new book How Infrastructure Works: Inside the Systems That Shape Our World. She will be joined in conversation by artist, design researcher, and writer SARA HENDREN.

About How Infrastructure Works

Infrastructure is a marvel, meeting our basic needs and enabling lives of astounding ease and productivity that would have been unimaginable just a century ago. It is the physical manifestation of our social contract—of our ability to work collectively for the public good—and it consists of the most complex and vast technological systems ever created by humans.

A soaring bridge is an obvious infrastructural feat, but so are the mostly hidden reservoirs, transformers, sewers, cables, and pipes that deliver water, energy, and information to wherever we need it. When these systems work well, they hide in plain sight. Engineer and materials scientist Deb Chachra takes readers on a fascinating tour of these essential utilities, revealing how they work, what it takes to keep them running, just how much we rely on them—but also whom they work well for, and who pays the costs.

Across the U.S. and elsewhere, these systems are suffering from systemic neglect and the effects of climate change, becoming unavoidably visible when they break down. Communities that are already marginalized often bear the brunt of these failures. But Chachra maps out a path for transforming and rebuilding our shared infrastructure to be not just functional but also equitable, resilient, and sustainable. The cost of not being able to rely on these systems is unthinkably high. We need to learn how to see them—and fix them, together—before it’s too late.

Praise for How Infrastructure Works

“The urgent problems of the modern era have instilled in so many of us a deep craving to more clearly see the systems that define our lives, to better understand when and why they fail, and to regain agency over a world that can seem too complex to understand much less affect. Fortunately, Deb Chachra has written exactly the book we needed. Revelatory, superbly written, and pulsing with wisdom and humanity, How Infrastructure Works is a masterpiece.” —Ed Yong, author of An Immense World

“A wonderful, wide-ranging narrative addressing the technical, social, personal, historical, and political aspects of the often-disregarded, invisible systems that support us. Forged of a huge heart and vast expertise, it shines with fierce humanity.” —Helen Macdonald, author of Vesper Flights

“How Infrastructure Works gives you x-ray vision into our built environment. It's also a ton of fun to read; Chachra is a gifted stylist and a first-rate intellectual guide.” —Clive Thompson, author of Coders: The Making of a New Tribe and the Remaking of the World
