**STARRED REVIEW** The Things We Make is a heartfelt ode in praise of engineers. Hammack, a long-time engineering educator, argues that far from merely being “applied science,” engineering boasts a robust method all its own, meaningfully separate from science. He offers several compelling examples of how engineering has changed our world and pushes back against the harmful myth of the lone inventor, which too often excludes the work of marginalized individuals, and perpetuates popular misunderstandings of what engineering actually is. The book starts with a description of how, in the Middle Ages, illiterate masons who didn’t know any math managed to build Gothic cathedrals that have stood for centuries. Other examples range from the development of color photography to the creation of designer enzymes, from such marvels as the modern computer chip to the quotidian soda can. He really runs the gamut with his examples, but all of them show how engineering utilizes rules of thumb and compromise solutions to resolve real-world problems.The Engineering Method, as much as the Scientific Method, stands as one of humanity’s greatest achievements. A must-read for anyone interested in engineering or the history of technology and human achievement.

The question of whether we’re alone in the universe is one of the most profound, and one which struggles to be taken seriously in scientific circles. It’s a question that extends beyond science into the realms of religion and philosophy. Evidence of intelligent life elsewhere would upend our understanding of our place in the universe. In his latest, Whitehouse summarizes the efforts we’ve made to search for other life in the universe, from SETI to UFO sightings, and the limitations such efforts must overcome. He assesses what we actually know about the likelihood that anyone else is out there. He also explores possibilities for what alien life might be like, an impossible question to answer, as we only have ourselves as an example, whereas life on other planets could be radically different. Finally, he examines what’s in store for the future of the universe with an eye toward whether or not life might survive. In the end, without definitive contact with extraterrestrials, any searches we make tell us more about ourselves than about life elsewhere.

As a rule, we try not to think too much about our poop. It’s one of the most taboo topics in our society, and our sewer systems are designed to keep it out of sight as much as possible. And yet, poop is a treasure trove of resources that we can use to make the world better. Scat can cure diseases and protect us against several major health concerns, aid in forensic and medical investigations, replenish our soils, and even become a source of energy, precious metals, and clean drinking water. New methods to make better use of our sewage can also help reduce pollution and greenhouse-gas emissions. Poop can help heal our planet. Nelson dives into the science of scat and profiles several examples of how people are using poop in new and innovative ways. Wide ranging and deeply informed, with a wry sense of humor, this is a solid recommendation for fans of Mary Roach, as well as anyone interested in out-of-the-box ideas to help fix some of our most pressing problems.
