Material World
I put this at #64 because Conway follows sand, salt, iron, copper, oil, and lithium into the ordinary world they quietly make possible. It belongs beside Energy: one book counts the power, the other restores the materials that digital language makes too easy to forget.
The long version
Ed Conway follows six materials—sand, salt, iron, copper, oil, and lithium—through mines, factories, supply chains, technologies, and political decisions. The modern world presents itself through services and screens, but its buildings, food, energy, communication, transport, and batteries remain physical. Each material carries engineering achievements and human costs. The book restores the extraction, heat, labour, geography, and dependence that disappear when an economy describes itself as digital or weightless.
Why it is here
Read it beside Energy because every technological future needs both power and matter. Conway turns abstract supply chains back into places and people. It belongs here because I build with machines while too easily forgetting what had to be dug, burned, refined, and moved before the machine reached me.
How to read it
Choose one object near you and trace each of its main materials back through processing, energy, transport, and labour. Keep a map while reading. When the scale becomes impressive, ask whose land, health, and political leverage are inside the number.
What it taught me
- 01
Digital systems depend on large physical systems whose materials and energy are easy for users to overlook.
- 02
A small group of basic materials supports an extraordinary range of modern services and strategic dependencies.
- 03
Decarbonisation changes demand for extraction and infrastructure rather than making material constraints disappear.
