STEM Books
I’ve reviewed 39 STEM-related
books (and counting). STEM is an acronym
for science,
technology,
engineering, and mathematics. As you may have seen in the news, there is a
push to improve STEM education,
interest students in STEM fields, and grow the number of workers
in these fields. The idea is that these
will be the skills needed by workers of the future. If you’re a STEM educator or a student
considering a career in STEM fields, you might like to take a look at some of
these books.

The Physics of Superheroes by James Kakalios
Kakalios, J. The Physics of Superheroes. New York: Gotham Books, 2005.
The Physics of Superheroes is a fun introduction to physics. Kakalios is a physics professor at the University of Minnesota, and childhood comic book fan, who created a freshman physics class that used examples from comic books to illustrate physics principles rather than traditional examples.
This book is not a physics textbook. For one thing, it is very light on math. Calculus was a prerequisite to the physics classes I took in college, but you can follow this book with no more math than a high school student would know. If higher math is necessary for a thorough understanding, Kakalios provides a general concept and moves on. This is a book for the nonspecialist.
Though written for a nontechnical audience, the book covers the range of physics you would find in an undergraduate physics curriculum. It moves from classical mechanics to thermodynamics to quantum mechanics. It demonstrates how seemingly esoteric and strange physical phenomena, particularly in the realm of quantum mechanics, make possible the technology that is all around us.
What makes the book entertaining is the use of comic books as sources of illustrations. Much of what is in comics is more fantasy than physics. Kakalios allows a “miracle exception” to explain the superheroes’ powers, but from their examines their feats form the point of view of solid science. Sometimes the comics get the science right.
Judging from the tone of the book, it seems that Kakalios has an affection for comic books. Though the main subject is physics, a secondary subject is the history of comics and some of their major characters. The comics fan will find something to enjoy as well as those seeking an approachable introduction to physics. Maybe it can bridge the gap between those with the button down collars and those in the Black Adam tee shirts.
This book shares something with more academic texts, namely footnotes. Kakalios’ footnotes deal more with the comics than the physics; he deals with the physics in the main text, but sometimes an explanatory note about the comics’ characters is helpful to the uninitiated. Some footnotes are tongue-in-cheek comments that lighten the tone of the more serious segments.

The Essential Engineer by Henry Petroski
Petroski, Henry. The Essential Engineer: Why Science Alone Will Not Solve Our Global Problems. New York: Vintage, 2010.
Policy makers seem to love science. I can see why. Science provides a sense of specificity, certainty and consensus. It contrasts with the vagueness, variability and competition that policy makers usually have to deal with. That is more like the world engineering.
This interrelation of policy-making, science and engineering, especially the latter two, is the subject of Henry Petroski’s book, The Essential Engineer. In particular, Petroski emphasizes the important, and often overlooked, role of engineering is solving pressing problems.
I doesn’t help that people conflate science and engineering, especially by thinking of engineering as branch or application of science. Petroski is clear about the differences. Science is about increasing knowledge. Engineering is about invention. Sometimes scientists do engineering, especially when they create a devise or process to help them in their work of discovery. Sometimes engineers do science, especially when their engage in research and experimentation to gain a better understanding or problems that are not well understood.
The movement of knowledge from science to engineering practice is well understood. Petroski describes how this became ingrained in American research and development policy. Engineering often precedes science and engineers often must invent solutions in areas that are not well understood by science. Galileo’s improvements to the telescope made possible his advancements in astronomy. The science of thermodynamics grew almost entirely out of the desire to understand steam engines, which engineers had been building and improving in the absence of scientific understanding.
This misunderstanding exacerbated by our culture and education. Policy elites and scientist generally have no education in engineering. As an undergraduate studying engineering, I took science classes with students majoring in the sciences. I took classes in political science, economics and other social science and business-oriented classes with students majoring in those fields. I would have been greatly surprised to find in one of my engineering classes a student who wasn’t majoring in engineering.*
Petroski does not try to bring down science. He’s a civil engineering professor at a sizeable university, so he has probably spent quite a bit of time doing science. He does distinguish how science is helpful, mainly as a warning. Science can help us identify and define problems and assess the risks involve. When we begin to devise solutions to those problems, especially when there is no definitive solution and judgment is needed to way the pros and cons of multiple possible answers, we are moving into engineering.
The Essential Engineer is not a technical book. It for anyone who may have an interest in the role of technology in addressing our problems, especially larger societal problems. Petroski draws illustrations from current events and history (he is a professor of history as well as engineering). The book is enlivened with a storytelling feel.
* There were exceptions. I took a course in food processing that was dual-listed in agricultural engineering and food science. It was a required course for both disciplines. Electrical engineering students almost automatically minored in math, and some clever and ambitious students double-majored in those subjects. With a little better planning, I could have swung a minor in agricultural economics, and I almost wish I had. When I got into wastewater engineering, I wished I had taken more microbiology. My pursuit of additional education lead to a graduate degree in public administration. Government agencies have been employers or clients most of my career. It is common for engineers to get a masters degree in business, especially as they become managers.
Henry Petroski also wrote Paperboy.

Feeding the Fire by Mark E. Eberhart
Mankind is hungry for energy. The United States is a huge consumer of energy, and our
lifestyle depends on it. This makes us, and other developed countries,
vulnerable. The burning of fossil fuels is leading to a changing climate that
could have many negative ramifications. Our dependence on foreign sources of
fuel, especially oil,
have embroiled us in wars oversees and made us uncomfortable allies with
nations that do not share our values.
Chemistry professor Mark E. Eberhart suggests that we need a good energy
diet. Unfortunately, after spending a couple of chapters of Feeding the Fire setting up the idea, he
ends up having only a little to say about an energy diet in the final chapter
of the book.
In between, however, he
tells an interesting history of energy from the big bang to our age. He also provides a primer
in thermodynamics aimed at an audience that hasn’t
studied science or engineering. If the book had purported to be
about that, I’d probably be speaking about it in glowing terms. If you’re
looking for a book that explains energy and how it works that is written for an
audience with little scientific background, this is a good option.
Though most of the book
concerns itself with the dispersal of energy through the universe and the
development of technology, the energy diet is mainly a matter
of policy. The central element of Eberhart’s
vision is an “energy-industrial complex” modeled on the way the U.S. military
works with industry on the long-term development, delivery and reliability of
technology. U.S. energy policy is so disjointed that in practice we have no
policy, but with imagination and discipline (and arguably the setting aside of
partisanship for matters of national security that transcend it) we could
develop a comprehensive policy that gets our efforts moving toward a more
secure, efficient and cleaner future. It doesn’t even need to be a perfect
policy, just a commitment to take specific actions and set specific standards
to make things better over time.
Eberhart has some
specific recommendations, especially related to the development of electric
vehicles and supporting technolgies. In the 12 years since Feeding the Fire was published, we’ve made some headway on many of
them. This is in spite of the fact that we still do not have a comprehensive
energy policy.
