Vaclav Smil keeps turning out amazing books. Making the Modern World, I just finished, and it’s pretty fantastic. It’s about this idea that we are still using more materials per person, even as advanced economies, though people talk about the dematerialization of steel, the amount of concrete, and other minerals. It’s classic Smil: really explaining how steel is improved, how concrete is improved, how you think about maintenance, and recycling, and limits, and what the new advances are. And really, the amazing progression.
