From personal notes to historical documents, paper has enabled the transmission of knowledge across generations. The material properties of paper, like its ability to hold a crease while remaining stiff, make it uniquely suited for functions like wrapping and storing information. However, even paper has its vulnerabilities, as seen in the degradation of receipts and the yellowing of older documents.
Key concept: “It is easy to underestimate the importance of note paper…we see only a blank page, allowing us to record on its surface whatever we choose.”
This highlights the power of paper as a technology that facilitates human expression and the recording of information, a seemingly simple material with a complex micro-structure that underpins its versatility.
3. Fundamental
Concrete, despite its ubiquity and importance in construction, often receives little aesthetic appreciation. Yet, this material, made from simple ingredients like powdered rock, water, and sand, is fundamental to our built environment. From Roman aqueducts to modern skyscrapers like the Shard, concrete’s strength, durability, and moldability have allowed us to build on an unprecedented scale. However, its vulnerability to human error and environmental factors highlights the importance of careful design and ongoing maintenance.
Key concept: Concrete doesn’t dry out. Quite the opposite, water is an ingredient of concrete.
This counterintuitive fact underscores the chemical complexity of concrete and how its strength and resilience depend on water, not its absence.
4. Delicious
Chocolate, a “deliciously engineered material,” is designed to deliver a multi-sensory experience. The carefully controlled crystal structure of cocoa butter and the release of flavors upon melting create a unique and pleasurable sensation. From its origins as a bitter drink to the modern chocolate bar, the history of chocolate highlights the role of scientific understanding and innovation in transforming a simple ingredient into a complex and highly desirable product.
Key concept: “Chocolate is designed to transform into a liquid as soon as it hits your mouth.”

6. Imaginative
Plastic, an “imaginative” material that has revolutionized everything from packaging to medical implants, often receives a bad rap. But plastic has also played a crucial role in the development of cinema, from celluloid film to the very structure of movie theaters. Through a series of imagined scenes, the book illustrates how plastic’s versatility and moldability have enabled the creation of new forms of art and entertainment.
Key concept: “Cinema was about the stars of the silver screen, the flickering lights, the velvet seats, and the whir of the projector.”
This quote, delivered by a passionate film buff, captures the nostalgic appeal of cinema and highlights the multi-sensory experience it offers, contrasting it with the seemingly less glamorous role of plastic.
7. Invisible
Glass, a material we often take for granted due to its transparency and seeming “invisibility,” is essential to human civilization. From windows that let light in while keeping the elements out, to lenses that have revolutionized science and technology, glass has shaped our world in profound ways. However, its fragility and lack of tactile appeal can also make it seem less valuable than other materials, despite its essential functions.
Key concept: “People do not tend to wax lyrical about glass in the way that they do about, say, a wooden floor or a cast-iron railway station.”
This quote encapsulates the often-unappreciated role of glass in human civilization and how its very transparency and invisibility can lead to its being overlooked, despite its essential functions.
8. Unbreakable
Graphite, a material often associated with pencils and lubricants, is revealed to be a source of “unbreakable” strength at the atomic level. Its structure, made of layers of hexagonal carbon, has inspired the development of new materials like carbon fiber and graphene, which possess extraordinary properties. The surprising fact that graphite could be stronger than diamond if not for weak bonds between its layers highlights the importance of understanding the atomic structure of materials.
Key concept: “If it weren’t for the weak van der Waals bonds, graphite would be stronger than diamond.”
This surprising statement challenges conventional assumptions about strength and hardness and highlights the importance of atomic structure in determining material properties.
9. Refined
Porcelain, a “refined” material that has captivated civilizations for centuries, exemplifies the complex interplay of materials, culture, and technology. From the careful selection and mixing of clays and minerals to the precise control of firing temperatures, the creation of porcelain requires a high degree of skill and artistry. The delicate translucence and resonant ring of a porcelain cup are not just aesthetic qualities but indicators of its underlying strength and durability.
Key concept: “The ringing sound of a cup is the clearest and surest way to know whether it is fully formed inside.”
This simple test highlights the deep connection between material properties and human senses, and how seemingly insignificant details, like the sound a cup makes, can reveal important information about its structure and quality.
10. Immortal
Biomaterials, used to create implants that integrate with the human body, offer the potential for “immortal” life, or at least extended health and mobility. From titanium screws that repair ligaments, to self-healing concrete that mimics biological processes, to 3D-printed organs grown from a patient’s own stem cells, these materials are pushing the boundaries of what is possible in medicine and engineering. However, the high cost and ethical implications of these technologies raise important questions about access and equity.
Key concept: “This chronic shortage [of organs] is having three effects…long-term health care…patients…die before a suitable organ becomes available…black market for organs.”
This quote emphasizes the urgent need for alternative solutions to organ transplantation and highlights the potential of biomaterials and tissue engineering to address this critical healthcare issue.
11. Synthesis
From the mundane to the extraordinary, the materials that surround us are not just inert substances but complex expressions of human needs and desires. The multi-scale architecture of materials, from atoms to macroscopic objects, determines their properties and behaviors, and our understanding of this architecture allows us to design and create new materials with tailored properties. This “synthesis” of scientific understanding, technological innovation, and human values is what shapes our material world and ultimately, ourselves.
Key concept: “Materials are…a reflection of who we are, a multi-scale expression of our human needs and desires.”
This statement encapsulates the core message of the book, emphasizing the deeply intertwined relationship between humans and the materials they create and use.
