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 René 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.

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 Computers of Star Trek by Lois Gresh & Robert Weinberg

Star Trek fans, I’m one of them, have praised the show for the way it has anticipated technology. It used to be quite the thing to compare a flip phone to the Trek communicator.

However, have you ever watched a rerun of the show and seen something that now seems quaint, even ridiculous, especially when it comes to computers? Back in 1999, Lois Gresh and Robert Weinberg published observations like this, along with a few kudos for the shows, in The Computers of Star Trek.

The book covers episodes from the original series (TOS), The Next Generation (TNG), Deep Space Nine, Voyager and the films through Insurrection. While all the series, even the more recent prequel series Enterprise, depict a technologically advance future, none are focused on technology. They are more focused on telling stories that deal with the social issues in the periods in which they were made.

Gresh and Weinberg note this: Trek computers are mainly supersized versions of the computers of the time the show is made. In some ways, the Federation computers in the show are throwbacks to 1970s and earlier era mainframes, even though smaller, networked computers were becoming the dominant model when the revival series started in the late 1980s. This continued even as the Internet emerged and became part of the popular culture.

Of course the producers of the show aren’t especially interested in how computers actually work; they want to make an entertaining TV show and sometimes explore what is going on the society around them through the lens of a fictional future. Trek is interesting in this regard because it shows the attitudes of people about computers over time. In TOS computers are regarded with skepticism: computers break down, Spock is a hacker who takes over the ship, artificial intelligences take over planets but get fried by the illogic of emotions. By the time of TNG, computers are ubiquitous and acceptable—everyone uses them—but the threat of the Borg show concerns that computers might take over our lives and cause us to be depersonalized, destroying our individual identities.

An almost 20 year old book can’t help to be out of date, and the authors inevitably miss on some predictions. For instance, in their criticism of Trek’s take on medicine (not very advanced at all except when it is practically magic), the mention Army research into smart shirts that will monitor wearers for vital signs and injuries. It was a tee shirt with sewn in sensors that could be made for $30 (in 1998 dollars). Though we now have a lot of wearable technology, hospitals, soldiers and health nuts aren’t making use of cheap tees that keep track of their status moment by moment.

I don’t bring this up to knock the authors’ predictions. It’s hard to predict the future, especially by projecting from the current state of the art. Trek writers arguably haven’t tried very hard, but the show really isn’t about technology anyway.

Life's Matrix by Philip Ball

Water is a chemical essential to human life and culture, and it is possibly the oddest common substance. Physicist and science writer Philip Ball describes the nature of water, both scientific and cultural, in Life’s Matrix (originally published in the United Kingdom as H2O: A Biography of Water).

Ball begins at the very beginning—the big bang. Hydrogen, the simplest atom and most abundant element in the universe, appeared early in the universe. Oxygen is forged in stars and has become the third most abundant element. There is water in space. Ice seems to be common in the far reaches of the solar system. It has been found on the moon and stars and a few molecules appear in the cooler spots on the sun.

We have found no worlds yet that have as much liquid water as ours. The water cycle has shaped Earth. Our weather comes largely from the interplay of water and energy. Even the water locked up in the ice of our poles and glaciers shape the land, influence the weather, and affect the movement of heat, water and salt in ocean currents.

Ball tackles all phases of water, including a few exotic forms that only occur in extreme conditions created in laboratories. That water exists as vapor, liquid, and solid within the fairly narrow range of temperatures that are common on Earth make it unique. This is just one of its unusual properties. The structure of the water molecule is described in the book along with the physics that explain its behavior, to the degree that such things are even known.

Our understanding of water as a compound of hydrogen and oxygen is a relatively recent thing. For a long time, water was thought of as an irreducible element. This makes sense on some level. Water is essential to life as we know it. It is irreplaceable. From the perspective of living creatures, and in almost every culture, water is a fundamental material.

In the final chapter, Ball moves away from the hard sciences to culture, economics and policy. Water of the quality needed for drinking, and even the lesser quality needed for other things, is scarce and unevenly distributed on the planet. To take a serious look at water is to be drawn to issues of health and wealth. Growing population and changing climate will put increased demands on the available fresh water, and we need to consider how we are going to manage it. Ball takes a look at some of the hot spots.

The book is intended for a broad audience. I think it is probably more accessible to someone with some education in the sciences, especially chemistry or physics, but someone had a high-school level class in these subjects they should be able to follow along.

In addition, the book is 16 years old, so necessarily out of date in some respects. I suspect that much of the physics, chemistry and biology described is still sound. Similarly, there is unlikely to be discoveries in history that would seriously outdate the book, even in the interesting section on dead ends and “pathology” in water science.

Waste and Want by Susan Strasser

An old proverb relates trash and treasure as a matter of perspective. In Waste and Want, Susan Strasser describes American’s changing perspectives on waste from the colonial era to our own day.

In the colonial and revolutionary period of American history, manufactured objects were rare and expensive. Repair and mending were common even among the wealthy because it was difficult and costly to replace objects. In addition, the various types of home industry practiced by both men and women equipped them with skills in handling materials that made them adept at repair. Even when and object was beyond repair, it parts, or the material it was made of, might be usefully repurposed themselves or as part of an assembly. This lack of goods and facility with handling materials made bricolage common. Because things had durable value, people had a sense of stewardship relating to them.

Strasser establishes this as a beginning state. The development of industry and consumerism led to a current state in which all of these have been reversed. We have an abundance of goods, and many of them are inexpensive. We work in factories and offices where we do not develop skills for repair, and particularly have lost familiarity with materials needed for practical bricolage. These and other forces, particularly those related to health and cleanliness, have resulted in waste being something of the home where additional value may be extracted to something that is the realm of specialists that is taken away and handled by government agencies or specialized companies.

There are many stages in this development. It is interesting to me that the value of household waste as raw materials American industry provided a mechanism for poor and rural people to purchase manufactured goods. Even so, as industrialization made more goods available, along with larger quantities of more manageable waste, household waste became less valuable, and reuse and recycling became associated with poverty.

By the end of the 1920s, consumer culture was established in America, and it reinforced the trends identified by Strasser.  Planned obsolescence was developed in the automotive industry, and along with the craze for fashion, it took hold for almost all consumer goods. Even during the Great Depression, when lack of credit and unemployment made doing it yourself attractive, there was an assumption that people had access to new and old consumer goods and their packaging. Even during this period of economic distress, demand for certain types of consumer goods grew. Thrift was reimaged for a consumer age. For instance, refrigerators became commonplace, and instead of being presented as luxury items they were sold on the notion of thrift, allowing housewives to save on food by keeping leftovers and buying in bulk.

People were encouraged to conserve and recycle to support the war effort during World War II. However, this did little to reverse changing attitudes that valued the new over the old and saw little value in trash. People had jobs and money, and wartime rationing created a pent up demand for goods that was unleased after the war. Disposable goods and packaging represented cleanliness and convenience; it was freedom from dirt and drudgery. There was no value in trash, which was taken away by collectors.

There were reactions against this even in the 1950s. They grew into the counterculture of the 1960s and 1970s, which were skeptical of corporations and consumerism. The environmental movement also grew out of this counterculture. Reuse of second-hand goods became more acceptable for even middle-class families, though few had the skills needed to rework these items to make them seem new or adapt them to current fashion. Little used goods were seen to have some value that could be recovered through yard sales. (I grew up on a stretch of highway that now boasts and annual 100 mile yard sale.)

This counterculture has not resulted in a broad return to a stewardship of things. Strasser suggests that a rising ethic of environmental or resource stewardship may lead to the mitigation of problems related to the abundant trash created by disposable and rapidly obsolete goods. There is no turning back, but we might find new reasons and ways to reduce use, reuse, and recycle.

Attitude is Everything by Jeff Keller

Keller, Jeff. Attitude is Everything: Change Your Attitude…and Change Your Life. Tampa, FL: INTI, 1999.

In Keller’s book, you will find much of what you will find in many similar self-help books. (Perhaps I have read too many.) Attitude is Everything is superior to some others in its genre in that it is short and the author’s enthusiasm for the subject comes through.

The book is laid out in three parts concerning thinking, saying and doing. Each chapter is an essay on a topic relating one of these subjects.

It all starts with thinking. Success or failure begins in the mind because our thinking affects everything we do. Today some seem to have the idea from books like The Secret that it is all about thinking. Keller encourages his readers to be realistic as well as positive. He writes, “Success requires effort, commitment and patience.”

What we say and what we think are closely related. Keller wants us to be positive in our speech because what we say, along with our thoughts, sets us up to act in ways that lead to success or not. Even our answer to the question “How are you?” can affect our outlook and wellbeing.

The part I like most about the book is that it gives attention to the necessity of action. The advice in one of the action chapters, entitled “Networking That Gets Results,” is worth reading and using. I get more business from referrals than any other sources. I value my network more than any other marketing took because it works best for me. This is not about mercenary networking; I hope I can be a good friend to my friends and as helpful to my associates as they have been to me. Keller offers good advice on building and using your network.

Water by Marq de Villiers

I originally posted this review at Infrastructure Watch, where I write about civil infrastructure, the environment and other matters of technology.

de Villiers, Marq. Water: The Fate of Our Most Precious Resource. 1999. Boston: Houghton Mifflin, 2000.

Marq de Villiers serves as a guide on a tour of water problems, conflicts and occasional solutions around the world. Though he is not an alarmist, his book seems to indicate that the problems have so far greatly outpaced the solutions.

There are several aspects of water problems and conflicts that de Villiers considers: natural, technological and political. In each area, he provides specific examples of water in or nearing crisis.

The natural distribution of fresh water in the world is uneven. That may be the fundamental aspect of water problems: even where it’s seemingly abundant, it doesn’t occur where and when people want it to make use of it. In parts of the world, this is a dire situation.

The technological solutions people have applied to correct this distribution have resulted in some amazing works of engineering since early in human history. It has also had many unintended consequences. Irrigation that made marginal land productive has made some of that land useless, even desert, through increased salinity. Dams, drainage and transfers have created ill effects in regional climates. Water mining, pollution and other human activity are also threatening the quantity and quality of water even in developed nations. There is hope in the technological area in that much of this harm may be reversible and the human ingenuity that created these technologies might also create sustainable solutions to our water needs.

Political considerations are very important to water issues, particularly when considering the possibility of conflict, even outright war, because of water scarcity. The Middle East and North Africa come to mind as hot spots where water is a critical issue; de Villiers enlightens both the current situation and history of these regions. Though mistrust runs deep between the nations in this region, even seemingly friendly ones, there is hope for solutions to their water problems. North America has its water problems to, and the problems on the Colorado River are surprisingly similar to those on the Nile. The differences in water availability in the United States, Mexico and Canada also makes for interesting relations between these close and usually friendly neighbors. China may present the largest political problems related to water and it’s food production and population that threatens to push it into crisis.

The book closes with four general strategies for dealing with the world’s water problems. First, get more water by either bringing it in from elsewhere or making it (i.e. desalination). Next is conservation and pricing to reduce demand and encourage using water in the most valuable ways. Third is population control; de Villiers seems relieved that world populations have been growing more slowly without major intervention. Finally, you can steal water from others. Since 40 percent people worldwide live in watersheds that cross national boundaries, it becomes a complicated matter of who has what right to the water and this is a potential source of water conflict, though not insurmountable.

P.S., here is a little something extra for those of you interested in China, especially the probably fictional Emperor Yu the Engineer.

You Can Write for Magazines by Greg Daugherty

Daugherty, Greg. You Can Write for Magazines. Cincinnati, OH: Writer’s Digest Books, 1999.

You Can Write for Magazines is a practical primer on writing and selling magazine articles. This short book is loosely divided into three parts: how magazines work, how to write types of articles that are popular, and how to handle the business of writing.

As an editor, Daugherty is familiar with how magazines work. Since this is a book for writers, it treats the subject lightly and briefly. It’s enough to help the novice freelancer know what to expect without unnecessary detail. In an early chapter, he juxtaposes what is going on with the writer with what is happening at the magazine.



For the hopeful freelancer, the several chapters on popular types of articles are likely to be of most interest. These chapters are short and won’t save writers any of the hard work of putting together articles. They will help them start of in the right direction and avoid problems. This section works well as a possible reference. Since each chapter deals with a single type of article, one can turn to it for relevant pointers without sorting through the entire book. They also highlight the types of materials magazines use beside long feature articles.

The final chapters are very important to those freelancers who might hope to make a little money from their efforts. They cover the art of selling, the writer’s rights and money management. As in the rest of the book, Daugherty concentrates on the essential facts that will be useful to the writer, especially a beginner.

Throughout, Daugherty’s own writing style can be a lesson to beginning magazine writers. He sticks to the main points, focuses on the important aspects of his subject, organizes each chapter well and writes with an appropriate tone. Each chapter could be an article on some aspect of magazine writing.

Stories for a Man’s Heart by Al and Alice Gray

Gray, Al, and Alice Gray, eds. Stories for a Man’s Heart. Sisters, OR: Multnomah, 1999.

This is part of the Stories for the Heart series, one of Christian publishing’s entries into a market that has boomed since the creation of the Chicken Soup books. It has over 100 short selections from a variety of books and authors.

The stories are organized into categories meant to represent aspects of the masculine life. They are virtue, love, motivation, encouragement, fatherhood, sports, legacy and faith. Nearly all are from Christian authors; all were chosen by Christian editors.



Some of the sections are stereotypical “man” stuff, like sports. I could really only relate to fishing and that more as a casual catcher of pan fish than a serious sportsman. By contrast, fatherhood is something universal; even those who aren’t fathers had one and were affected by his presence or absence and relationship with him.

I’ve never read a book of this kind before, so I don’t have much context for it. I enjoyed it more than I thought I might, mainly because I enjoy hearing people’s stories. It is a little like hanging out at a family gathering or with some friends as they swap anecdotes.

The motivational or lesson teaching value of the book is probably depends a lot on the reader. The stories are not fables; they are vignettes from life, mostly from the lives of the authors. There is not interpretation or lesson added to the stories; they only appear of the authors included them. You may find some of the stories resonate with you or motivate you, but don’t expect to find a series of case studies from which definite lessons are drawn.

Book series like this might be titled Stories Calculated to Make You Cry. This book has four tearjerkers. Results may vary. If you cry at weddings, funerals, graduations or sad movies, you may find many more of the stories move you to tears.

Seamless Government by Russell M. Linden

Linden, Russell M. Seamless Government: A Practical Guide to Re-Engineering in the Public Sector. San Francisco: Jossey-Bass, 1994.
ISBN 0-7879-0015-X

Russell Linden’s book is a guide to the principles and practice of re-engineering in public sector agencies. He defines and explains the concepts of re-engineering and provides a thorough, step-by-step process for conducting a re-engineering project.

I was interested in the way he addressed the problem of defining customers. He identifies three groups: customers, who pay the agency; consumers, who use the agency’s services; and constituents, who have an interest in the mission of the agency. It is a simple way to organize stakeholders and identify potential beneficiaries, but it does not get the agency out of the need to resolve competing interests. For instance, my program will be streamlining the process for issuing construction permits. It will have little impact on the customer (the General Assembly) or the constituents (the public and environmental groups), but will be a benefit to the consumer (permit applicants).

In addition, I finally got the type of handling of case studies that I hoped to find in some of the other books. I was well impressed with the chapter devoted to the case studies of two agencies.

I would have liked to know more about the difficulties, specifically what does not work and sources of resistance to re-engineering. I think this could be well addressed by two more case studies. One would demonstrate how an agency used pilots, trickle-down and tell and sell and why these techniques failed. The second would demonstrate how and agency addressed the fears and resistance of managers, specialists and central staff.



I originally wrote this review in 1999 when I read the book for a class. I don’t remember what construction permitting process improvements I had in mind, but the probably had something to do with state and federal permits for wastewater facilities. I think my old agency is still behind the ball when it comes to using information technology in the permitting process. The job is made more difficult by the addition of new rules, new interpretations of existing requirements, and tight deadlines for getting state rules and practices in line with the present federal regime. I’m full of opinions about both the state and federal approach to wastewater regulation, especially permitting. I’ll refrain from further editorializing here. Presently, I provide management consulting and administrative services to utilities. You can find out more about my consulting practice here.

The Leadership Triad by Dale E. Zand

Zand, Dale E. The Leadership Triad. New York: Oxford UP, 1997.
ISBN 0-19-509240-6

Dale E. Zand discusses what leadership means and what its requirements are in a rapidly changing world. He calls this new leadership “triadic.” Three principles are the foundation of triadic leadership: knowledge, trust and power. He devotes parts of the book to each, defining the principles and demonstrating their practical meaning in leadership. As the book progresses, he shows how these principles relate and build in each other.

The book is full of interesting material. An item that stands out in my mind is Zand’s discussion of knowledge work and how to manage knowledge workers. My job, at its best, is knowledge work. I was surprised to find my coworkers, myself, and our reactions to different management approaches succinctly described. As Zand predicts, we respond positively to supervision that recognizes the nature of knowledge work and our professionalism. Supervision that fails to recognized this stirs up resentment.

Zand, like several other authors, makes good use of short case studies for illustration. It is not enough; it just whets my appetite. I think a few detailed, chapter-long case studies related to the use of the three principles would add a lot of depth to the book without adding many pages.

I originally wrote this review in 1999 when I read the book for a class. I’m still a knowledge worker, though as an entrepreneur instead as an employee. You can find out more about my business here.

Dreams of Iron and Steel by Deborah Cadbury & The Lighthouse Stevensons by Bella Bathurst

In Dreams of Iron and Steel (New York: HarperCollins, 2004), Deborah Cadbury tells the stories of seven great works that cover over a century of engineering history. Originally published in Great Britain as Seven Wonders of the Industrial World, the book was a companion to a BBC television series. The projects covered vary widely from a sewer built under a metropolis to a bridge that towered above the skyline of its day.

The oldest of these (still standing like all but one of the other projects) is the Bell Rock lighthouse. The Bell Rock sank many ships that sought shelter from North Sea storms in Scotland’s Firth of Forth. Robert Stevenson, grandfather of author Robert Louis Stevenson, designed and oversaw the construction of a tower on it. The rock was a formidable construction site. It sat eleven miles from land. High tide covered it with as much as 16 feet of water. Low tide exposed an area only 250 by 130 feet. Yet Stevenson and his men built a 100-foot, stone tower on it. They did it 200 years ago.

By the middle of the nineteenth century, several wonders were built almost at once. The Great Eastern, built by Isambard Kingdom Brunel, was twice the size of any other ship. Though a commercial failure, it set the standard for the next generation of ships.

Brunel launched his ship into a dirty and diseased Thames. Joseph Bazalgette sought to make the river safer for London residents. He built sewers under an ancient city that had grown to 2.5 million people and sprawled over 80 square miles.

In the American West, rival firms raced across the continent to build a railroad that would unite a nation recovering from civil war. In New York, John and Washington Roebling tackled the broad East River with their Brooklyn Bridge. They risked their lives and reputations on the longest span of the day and a material untested in bridges—steel.

The twentieth century inaugurated bigger feats. First proposed in 1879 by Vicomte Ferdinand de Lesseps of France, builder of the Suez Canal, the Panama Canal defeated most of those tried to build it. Even the United States poked at the mountains in futility until John Stevens, a railroad engineer, upgraded the infrastructure and equipment. When Stevens left the canal, a frustrated Theodore Roosevelt put military officers in charge. Lieutenant Colonel George Goethels, an engineer with extensive lock and dam experience, saw the canal through to its completion shortly before World War I.

The final project, America’s “damn big dam”, was build during the Depression. Hoover Dam was huge and constructed under difficult conditions. But construction engineer Frank “Hurry up” Crowe pushed and planned to get it done early and under budget.

Cadbury treats each project separately. However, they are linked by common elements.

Tragedy and setbacks touched each one. Thousands of men, usually poor laborers and sometimes children, were killed or injured to make these huge structures. They were beset by lack of financing, reluctance to try new methods and materials, bankrupt contractors, political opposition, corruption, greed, prejudice, and other human imperfections.

At their best, these engineers and their wonders are linked by the same qualities that appear in the best of engineering today. They had a vision to make people safer, healthier, richer, and freer. They created solutions to immense problems.

Robert Stevenson’s triumph at Bell Rock won the confidence of the Northern Lighthouse Board. It also launched an association between the Stevenson family and Scottish lighthouses that lasted four generations. During their tenures in the office of engineer for the board, Stevenson and his sons dominated the design, construction, and operation of the lights. Bella Bathurst tells their story in The Lighthouse Stevensons (New York: HarperCollins, 1999).

This book has its own kind of variety: technical, professional, and personal. It covers the construction and technology of several lighthouses, the masterpieces of Robert and his three sons. They not only built towers, but also improved their design and the design of the lamps, reflectors, optics, and mechanical systems that operated in them. One even studied the waves that assaulted their works.

It shows that engineering is more than simply design and construction. The Stevensons were also managers, fundraisers, businessmen, public servants, purchasing agents, manufacturers, contractors, and more. Their work included a broad section of what engineers do.

The book is also a biography of these four men that reveals the dynamics of the family. Robert insisted his sons join the family profession and business. Only one, David, seemed to take to it naturally. Only David’s sons filled the next generation of lighthouse Stevensons. Alan and Tom were more inclined to work in literature and the arts. Alan proved himself to be a capable engineer by building a 138-foot light at Skerryvore that could withstand the elements and exhibit a simple beauty. He became so disabled by disease, Bathurst suggests it was muscular sclerosis, that he gave up his work with the lighthouses. He managed to work irregularly as a writer. His works include and encyclopedia article on lighthouses and a translation of Greek poems. Tom shared Alan’s artistic leaning, but not his intensity and focus. He and David eventually divided the engineering work for the Northern Lights.

Not everyone is cut out to be an engineer, of course. As Robert Louis Stevenson said about his internship in the profession, “He is a wise youth, to be sure, who can balance one part of genuine life against two parts of drudgery between four walls and for the sake of one, manfully accept the other.” But some managed to catch what Marion Allen, a laborer on the Hoover Dam, called constructitis. “Sometimes one thinks he is cured,” said Allen, “only to have a relapse when he goes by fresh concrete or catches the smell of fresh sawdust from new lumber. Anyone with this affliction has to start construction of some kind, even of only to dig a hole and fill it up again.”
