The Things We Make: The Unknown History of Invention from Cathedrals to Soda Cans by Bill Hammack Summary
Overview of The Things We Make
Discover how cathedrals and soda cans share engineering DNA in Bill Hammack's eye-opening exploration of human innovation. Endorsed by Adam Grant, this book reveals the hidden "engineering method" that built our world - no math degree required to think like a creator.
- Inventions stem from generations of trial and error, not lone genius
- Engineering solutions prioritize practical rules of thumb over theoretical perfection
- Breakthroughs demand cross-disciplinary collaboration, not isolated eureka moments
- Optimal designs balance competing priorities through deliberate compromise
- Engineering solves real-world problems before science explains underlying principles
- Medieval cathedrals and soda cans follow identical engineering method principles
- Every invention builds on centuries of accumulated practical knowledge
- The engineering method blends structured problem-solving with creative improvisation
- Bill Hammack reveals humanity's universal problem-solving blueprint in creations
- The Things We Make reframes progress as collaborative human achievement
- True innovation embraces imperfection to deliver functional solutions faster

FAQs About The Things We Make
What is The Things We Make by Bill Hammack about?
The Things We Make explores the hidden "engineering method" behind humanity’s greatest inventions, from medieval cathedrals to soda cans. Bill Hammack reveals three core strategies: iterative trial-and-error, building on historical knowledge, and embracing trade-offs to solve practical problems. The book emphasizes engineering’s distinct role in shaping daily life, contrasting it with pure science while celebrating collaborative, context-driven innovation.
Who should read The Things We Make?
This book is ideal for history enthusiasts, STEM educators, and curious minds interested in how everyday objects are designed. Engineers will appreciate its focus on practical problem-solving, while general readers gain insight into the iterative, often overlooked processes behind technological progress.
What are the key concepts in The Things We Make?
Hammack identifies three pillars of engineering:
- Trial and Error: Incremental improvements over generations, exemplified by the evolution of light bulbs.
- Historical Continuity: Innovations like microwave ovens adapting wartime radar technology for kitchens.
- Trade-Off Acceptance: Balancing cost, efficiency, and accessibility, as seen in the design of skyscrapers and soda cans.
How does The Things We Make differentiate engineering from science?
Engineering prioritizes functional solutions over theoretical knowledge, using science as a tool rather than an end goal. For example, medieval masons built cathedrals using geometric heuristics long before scientists formalized structural mechanics.
What historical inventions are highlighted in the book?
Key examples include:
- Gothic Cathedrals: Master masons using rope-based geometry for arched designs.
- Microwave Ovens: Repurposed from military radar systems through material cost compromises.
- Photography: Iterative refinements by multiple inventors over decades.
Does The Things We Make address ethics in engineering?
Yes. Hammack argues engineers must weigh societal impact, advocating for solutions that balance functionality with moral responsibility—like designing inclusive technologies or sustainable materials.
How does Bill Hammack’s background influence the book?
As a Carl Sagan Award-winning educator and creator of the "engineerguy" YouTube channel, Hammack combines technical expertise with storytelling. His focus on accessible explanations mirrors his viral videos, demystifying complex topics through historical narratives.
Is The Things We Make based on academic research?
Hammack synthesizes centuries of engineering history, citing innovations like Josiah Wedgwood’s ceramics and Charles Parsons’ steam turbines. The book bridges scholarly rigor with engaging prose, avoiding jargon to appeal to broad audiences.
What criticism has The Things We Make received?
Kirkus Reviews praises its clarity but notes the engineering-centric perspective may oversimplify scientific contributions. Critics suggest deeper exploration of modern challenges like AI ethics would enhance its relevance.
How does the book explain collaborative innovation?
Hammack debunks the "lone genius" myth, showing how inventions like electric lighting emerged from cumulative efforts. For instance, Edison’s bulb relied on prior work by Swan, Faraday, and others.
Why is The Things We Make relevant in 2025?
As AI and green tech dominate headlines, the book’s lessons on adaptive problem-solving and ethical trade-offs offer a framework for addressing contemporary issues like climate change and automation.
Where can I find supplemental material for the book?
Hammack’s YouTube channel "engineerguy" provides visual explorations of topics covered in the book, such as microwave engineering and cathedral design, enhancing understanding through multimedia.

Quotes from The Things We Make
The true engine of innovation lies elsewhere-in what engineers call "rules of thumb."
"Best" means juggling hundreds of restrictions and parameters within cultural contexts.
Engineering rules simply become obsolete when materials or contexts change.
The design existed almost entirely in his memory...
...our remarkable ability to create solutions despite incomplete information.
