The Pleasure of Finding Things Out by Richard P. Feynman

The Pleasure of Finding Things Out is a collection of interviews and speeches of physicist and Nobel Prize winner Richard P. Feynman. The theme that runs through most of these items is Feynman’s ideas about what science is and how it is practiced.

 To Feynmen, the essence of a proper scientific attitude is doubt (a version of this idea goes back to RenĂ© Descartes). It is an honest acceptance that you don’t know anything for certain, and you may accept other ideas about what is most likely true about the world in light of new experiences and better measurements. Science is the testing of ideas to see if they conform to reality and the knowledge that accumulates as a result.

 The physicist is critical of some of the social sciences, some parts of psychology and education research. They use experiment and measurement and other forms from science, but they do not produce results in the manner of the physical sciences. He doesn’t suggest the end of research in these areas, but that they tend to present findings as if there is “scientific” certainty when things are actually very uncertain.

 Feynman led an interesting life, and I took particular interest in his experiences related to very important engineering and policy issues in his lifetime. In one of the interviews, Feynman discussed his work on the Manhattan Project and life at Los Alamos. The editor included Feynman’s minority report on the investigation of the destruction of the space shuttle Challenger, which resulted in the death of all the astronauts on board.

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.

God's Equation by Amir Aczel


Amir Aczel wrote God’s Equation following the 1998 announcement of studies that indicated that we live in an open universe that will continue expanding without end. This is in contrast to theories that the universe might be closed, with gravity eventually pulling everything back in to a great collapse, or stable, with the universe continuing to expand at an ever slower rate. He attempts to show for a lay audience how these discoveries were built on the work of Albert Einstein and complex forms of geometry.

It is complex. Aczel does not dive too deep into the math. Most of his intended audience wouldn’t understand it—it is beyond any math I’ve mastered. It is rooted in Einstein’s general theory of relativity and his field equation, which describes it mathematically. Many people are familiar with E=mc2. It is simple and it is fairly easy to understand what it is describing. The field equation may look fairly simple when written out, but behind it is very complex math that has complex ramifications.

I think a lay person could read this book and have no better understanding of the physics and math of our expanding universe than he did before. I’m not sure that understanding complex physics is the great value of the book anyway.

To me, the value of the book is the way it shows how science works. Aczel demythologizes the process, especially in relation to Einstein, without devaluing it or the accomplishments of leading scientists. For instance, the myth of Einstein is that he came up with the theory of relativity in an instant due to his extraordinary genius and it instantly revolutionized science.

The reality is that, even though Einstein was way ahead of his contemporaries, it took him years of effort and false starts to develop general relativity. He had help and input from other physicists and mathematicians. His work was met with skepticism. It took many years for Einstein and others to flesh out the ramifications of his theory, and for astronomers and other experimental scientist to confirm them.

Another bit of demythologizing is that Einstein wasn’t good at math. He simply wasn’t interested in math for its own sake, so he didn’t put in the effort as a student except to the degree he found it useful. Though Einstein came up with ideas with imagination that did not always depend on math, the fleshing out of his theories into sound physics required a lot of math. He applied himself diligently to mastering it, and it was quite advanced.

A physicist will seek more technical books on the subject of cosmology. Arguably a book that is nearly 20 year old may be a bit dated, too. However, I think it is still interesting history and how our understanding of the world is developed over time with imagination, diligence, debate, testing and the effort to many people.

The Girls of Atomic City by Denise Kiernan


World War II was a time when secrecy was often a necessary part of security. The secrecy surrounding the development to of the atomic bomb was particularly thick. Since that veil was lifted, Las Alamos, Nevada, has become strongly associated with the bomb, as it should be. However, there were other locations critical to the project. Denis Kiernan discusses one of them, Oak Ridge, Tennessee, in her book The Girls of Atomic City.

The Clinton Engineer Works was part of the Manhattan Project. Its purpose was the enrichment of uranium to supply the research, development and construction of an atomic weapon. When it was built, the Army took over thousands of acres of farmland in Tennessee, displacing the residents. Oak Ridge did not exist before the project.

As the title suggests, Kiernan focuses on the role of women at the Clinton Engineer Works, as the area was known when it was a military reservation. The book draws on her interviews with women who worked at the site; the experiences of nine particular women serve as guideposts for the story. These women served in a variety of roles: statistician, chemist, inspector, equipment operator, nurse, secretary, and janitor. Some became wives and mothers as well during the war years. It was an interesting time when there was space for women in science, technology and manufacturing, but not a lot.

Kiernan reaches outside of Oak Ridge to mention other notable women who played a part. German physicist Lise Meitner coined the term nuclear fission; she had Jewish ancestors and fled to Sweden as the Nazis came to power in her homeland. Earlier, Ida Noddack was the first to suggest that the atomic nucleus could split, an idea that was initially rejected by many scientists studying radioactivity and the inner workings of the atom.

The growth of families in a place designed solely for one purpose suggested a result that had not been considered when the Army started to build the Clinton Engineer Works. Oak Ridge was becoming a community and it eventually became an incorporated city (in 1958 by a vote of the residents after federal and state laws opened the opportunity). Though the population dropped dramatically from its war-time peak, Oak Ridge remained a center for research in nuclear energy and the peace-time use of radioactive materials as it transitioned to civilian control. Today the Oak Ridge National Laboratory continues research in energy and computing. The city of Oak Ridge continues as well, still connected to its past as a unique factory town, but in many way a city like any other.

The Power Makers by Maury Klein

Maury Klein’s book The Power Makers is a history of power from the Thomas Newcomen’s steam engine to the foundations of America’s electric grid.

Unlike many historians who look at the history of electric power, Klein gives a lot of attention to steam. We haven’t had steam engines directly powering industrial plants for decades, but steam turbines are still central to the production of most electricity in the United States. Even nuclear power plants use steam turbines to run their generators, they just use the heat from nuclear reactions rather than from the combustion of coal or natural gas to boil water and heat the steam to more than a thousand degrees.

Klein gives attention to many lesser known names in the history of power. He shows that Thomas Edison and George Westinghouse had rivals other than each other, such as Elihu Thomson. Nikola Tesla is well known as the genius who invented the AC motor, but other engineers helped develop his prototype into a commercial product, such as mathematically talented engineer Benjamin Lamme. Many talented inventors tried their hands at making electric lighting and power systems better. Only some of them had the vision, business sense, good partners and luck to turn their ideas into successful products. Few of them are widely known today.

Electrification had clear, direct effects in industry and transportation. Klein discusses how it’s influence reached into other sectors of the economy. Corporate management and finance changed to meet the needs of a growing new technology. For instance, Edison General Electric was able to take advantage of a new New Jersey law that allowed corporations to own businesses in other states. Electric companies grew, expanded and consolidated through numerous mergers and acquisitions. They had a demand for capital that nearly rivaled the railroads, another transformative technology that had shortly preceded electric power.

As the availability of electricity grew, certain industries were able to grow, too. Some chemical and metals manufacturing required abundant electric power to catalyze chemical reactions or generate the high temperatures of electric furnaces. Manufacturers flocked to Niagara after a lager hydroelectric power station started operation there in 1895.

Klein brings the many thread of his story of power together by reflections on three great fairs: the 1876 Centennial Exhibition in Philadelphia, the 1893 Columbian Exposition in Chicago and the 1939 New York World’s Fair. In the first, a giant steam engine that powered exhibits by means of belts and pulley was a significant attraction. By the second, electricity was on display, and the White City fairground was a model for testing AC power systems. By the 1939 fair, large power utilities of the type we would recognize today were becoming common. By then it was no big deal to flip a switch or pull a lever and get power so, unlike the previous to fairs, no dignitary undertook a show of doing it; the power was on from the start.

Move by Rosabeth Moss Canter

The major elements of America’s transportation infrastructure and policy frameworks are six decades old (or older in the case rail). We haven’t even kept up with the maintenance since then. In addition to taking care of what we have, we need to adapt to the changes in technology, culture and the economy that have occurred. Our policies haven’t been keeping up.

In Move, Harvard business professor Rosabeth Moss Kanter explores how we got here and how we can move forward. We got here by adopting a defense-oriented policy that emphasized cars (especially interstate highways) and air travel, largely ignoring rail, public transit and intermodal development.

The path forward has several elements. First is a focus on mobility. Transportation infrastructure is a technical, bureaucratic realm of deep silos. Mobility changes the focus to moving people and products around communities and the nation in whatever ways make sense. Physical mobility and economic mobility are tied, and if we want to strengthen our economic leadership on the world stage, we need to break down internal policy barriers to advancing the way people move.

That means developing a national strategy. Of course, a rigid approach won’t work because we have varied nation. However, national priorities and frameworks can make room for regional priorities, adaption and leadership.

Money is always in issue. There are potentials in public-private partnership (PPP), and that can be arranged in many ways. America has a world-leading freight rail system that has very limited public investment. Airports are generally owned by governments, and attempts to privatize them have meet a cool response from possible investors. However, there are examples of successful PPPs in which there is something for everybody.

I already mentioned that technology has come a long way in the past several decades, especially in the realm of communication and data analysis. Some transportation industries, such as airlines, are taking advantage of the opportunities in new technology, while other are lagging. There are many ways our transportation system can be smarter, and we need sensible ways of incorporating technology in ways that are safe without losing out on the benefits through unnecessary delays.

This requires leadership and vision, especially in government. Politicians are often motivated by short-term wins, but mobility is a long-term investment. We need leaders who can see passed the next election and the boundaries of party.

Finally, citizen engagement is important. Plans can quickly fail if the people who are going to use, pay for and otherwise feel the ultimate effects of new transportation policies and infrastructure are not informed, involved and empowered to take action that works for them.

How We Got to Now by Steven Johnson

The prevailing myth of invention is that it is the product of a solitary genius. Steven Johnson takes on this myth in How We Got to Now.

Johnson’s book is a history of invention with a focus on six particular innovations. He demonstrates that simultaneous invention is common, suggesting that societal knowledge, norms and expectations play a part in invention—at least in providing an environment in which certain types of inventions can be created and flourish.

Thomas Edison and the light bulb is the classic myth challenged by simultaneous invention. Humphrey Davy demonstrated an incandescent electric light in 1802 and Frederick de Moleyns received the first patent for a light bulb in 1841. By the time Edison got involve, people had been working on light bulbs for 30 years, and the potential for electric light had been now for 70 years. Edison and his team of collaborators deserve a lot of credit for creating a commercially successful electric lighting system, inventing solutions to many problems along the way, but is a story of systematic hard work.

Edison’s electric lighting system depended on a lot of prior technology, which relates to another of Johnson’s points: clusters of inventions. An invention can illuminate a previously unnoticed problem (or create a new one). For instance, the availability of affordable books that follow Johannes Gutenberg’s invention of the printing press revealed that many people were farsighted. This sparked a demand for reading glasses. The tinkering with lenses led to the invention of telescopes and microscopes. Galileo took up the telescope and made discoveries in astronomy that reshaped how people saw the world. Robert Hooke used the microscope to explore a seemingly alien world of the very tiny thing all around us, though the revolution he inspired took longer to bloom.

Johnson explores other aspects of invention and society. I think it is fair to say that his view of how invention works is a lot messier than the myth. Inventors are at the right place at the right time, with open minds that are prepared (likely by accident) to make a connection and a willingness to do the work of thinking, testing and making something new. They probe the boundaries of their fields, tinker and throw themselves into hobbies that bring them, often with companions, to crossroads that challenge their notions of where they can go and how they can get there.

On the whole, Johnson presents a vision of hope in our history. We are not dependent on genius or serendipity; human creativity is both a social and an individual process in which the collision of ideas leads to new ideas. We live in an era where the collision of ideas may be more possible than ever.
