London Underground Turns 150

The first train traveled the London Underground 150 years ago last month. It has grown to 249 miles of track that carry 3 million passengers daily. The Institute of Civil Engineers is observing the anniversary with events throughout the year.

Moon Water

When I was in high school, I enjoyed The Moon is a Harsh Mistress by Robert Heinlein. The title inspired my friends to tease me by saying it with dramatic flair. We all read science fiction, but I tended to read more hard sci-fi and older books (The Moon is a Harsh Mistress was 20 years old back then).

Anyway, in this book Heinlein anticipated that there would be water on the moon in the form of underground ice, which would be mined by settlers. Recent studies suggest that there is water ice on the moon, though we are obviously a long way from using it to quench the thirst of moon settlers. By the way, Heinlein also anticipated the Internet in this book, which I read when home dial-up Internet service was a relatively new thing and few people had computers in their homes.

Book Review: Cathedral, Forge, and Waterwheel by Frances & Joseph Gies

As much as I am interested in current developments in engineering, I also love the history of technology.  I’m pleased to repost hear a review of Cathedral, Forge, and Waterwheel by Frances and Joseph Gies that I previously posted at Keenan’s Book Reviews.

Among many the Middle Ages, between the Classical period and the Renaissance, is still thought of as the Dark Ages.  In their book Cathedral, Forge, and Waterwheel, Frances and Joseph Gies summarize scholarship that shows that the Medieval period was one of commercial and technological advancement that welcomed invention and the dispersion of knowledge.

The authors present a history of technology beginning with the contributions of Greek and Roman civilization and culminating with European developments on the cusp of the Age of Discovery.  The period in between is sometimes called the Dark Ages because of the lack of documentary history, the loss of the centralizing influence of Roman Empire, and the loss of Greek texts and knowledge in much of Europe.  The Gieses attempt to debunk the notion that this time was “dark” in the sense of being backward, especially superstitious, and lacking in advancement in knowledge, commerce, science, and especially technology.

From a technological point of view, the Middle Ages didn’t inherit from the Greeks or Romans much more than they might have learned for more ancient civilizations.  The Greeks little esteemed the useful arts.  The Romans were very practical adopters of technology, and they certainly did things on a large scale, but their main contribution was size and organization.  Medieval Europe more fruitfully borrowed and built upon technology from China.  Ancient China had very advance technology in comparison to contemporary civilizations, and the spice trade aided the transmission of technology, in the form of both devices and ideas, from East to West.

I think some of the greatest advances in this period occurred in architecture and materials.  In architecture, builders began to move away from Roman circular arches to something more like true arches.  This, along with the flying buttress, another Medieval development, made a new architecture of more open and brighter spaces possible.

Materials greatly improved, too, especially iron.  Either directly or as an idea, iron-making technology moved from China to Europe.  The blast furnace gave Europeans the ability to make cast iron.  Though casting iron parts was in their grasp, the more significant issue was that a lot more iron could be made.  Iron tools and parts made a host of other technology practicable.

Technological changes led to cultural changes, too.  Improved applications of animal and water power to agriculture and food production led to a transition away from slavery to a serf-tenant system in which the people who worked the field had a right to portion of their production.  Agricultural surpluses led to the development of cities along with a decline of bound serfs rise of free tradesmen.  The development of manufacturing led to all kinds of trade and improvements in commercial practices including double-entry bookkeeping.

I think this book may be a good introduction to the history of technology for people seeking an entry point to the field.  It is neither too technical nor too academic in its style.  It covers a period of history that is not as well covered by other popular books.  It also acknowledges and summarizes the technology of the immediately preceding and succeeding ages, so it covers a very wide timeframe.

Book Review: #STEM Books for #DeSTEMber

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.

I’ll confess that I’m not an educator, but I think most of these books will be accessible to high school and college students, and a few to middle school students.  The list is also a reflection of my career and interests in engineering, public health, policy, and history.  Even with these biases, I think it is a good list for someone looking for STEM-related books.

How to Build an Android: The True Story of Philip K. Dick’s Robotic Resurrection by David F. Dufty

I was fascinated by robots as a kid.  I enjoyed reading Isaac Asimov’s robot stories.  I longed for the Omnibot 2000 in the Sears Wishbook.

Robots have come a long way.  In How to Build an Android, David F. Dufty describes the short strange life of a very complex robot made to look and talk like science fiction author Philip K. Dick.  The robot had a very sophisticated and lifelike head and complex artificial intelligence.  As with most complex things, it was the work of many people who had to solve a lot of problems.

If you’re interested in robotics, this is an interesting nontechnical book.  In addition, you’ll get introduced to some freaky sci-fi.  You may even get as (somewhat) legitimate reason to use the word “Dickhead” (capitalized, it refers to a fan of PKD, so don’t go using it on anyone).

 

The Big Roads: The Untold Story of the Engineers, Visionaries, and Trailblazers Who Created the American Superhighways by Earl Swift

The Interstate highway system in the United States is one of the most enormous structures built.  Some of the prospective STEM students who read this may actually be younger than the Intestate system, though in some sense it is never complete because it needs constant repair and maintenance.  The Interstates were completed in the 1990s, but the Federal-Aid Highways go back to 1916.

 

Earl Swift wrote an accessible history of the Interstates in The Big Roads.  If you interested in automobiles or transportation, it’s a good read.

 

Dreams of Iron and Steel by Deborah Cadbury

Deborah Cadbury describes seven wonders of engineering in Dreams of Iron and Steel.  It covers almost a century of history, but many of the events are concentrated in the Victorian Era.  That was a time of great technological innovation.

 

Though the book is history, many of the structures still stand.  Railways, the Brooklyn Bridge, the Suez and Panama Canals, and Hoover Dam stand testament to an age of big engineering.

 

The Physics of Superheroes by James Kakalios

Though the memory of Professor Wragg’s sneer prompts me to not make this confession, part of my interest in science and technology came from comic books.  Iron Man was cool.  Spider-Man’s web shooters were very cool.  Superhero comics are full of fantasy, admittedly, but the strange, unrealistic science and technology they depict have inspired many to study STEM in reality.

 

Physicist John Kakalios uses examples from comic books to explore real physics in The Physics of Supeheroes.  Sometimes comics get there science right.  Even when they get it wrong, it can be instructive.  If you know what people are talking about when they refer to the “New 52,” you may find this book to be a great introduction to physics.

 

1089 and All That: A Journey into Mathematics by David Acheson

Here is another confession: I’m not especially interested in math.  I endured a lot of math classes to study engineering.  Reading David Acheson’s 1089 and All That did not require such endurance.  For one reason, it is a short book.  For another, Acheson doesn’t expect his readers to be mathematicians; it is enough to follow the outline of the math he discusses.

 

I recommend this book because so many people have a fear of math.  1089 can be followed by many high school students and older folks with math phobias.  Just take a deep breath, relax, and follow along as well as you can.  You’ll see that math can be interesting, useful, and even beautiful in a way.

 

The Brooklyn Bridge: They Said it Couldn’t be Built by Judith St. George

Judith St. George’s The Brooklyn Bridge is a short history of and iconic bridge.  Written for the bridge’s 100^th anniversary, it is also the story of the engineers who sacrificed life and health to see it completed: John Roebling and his son Washington.  John Roebling was a German immigrant who built many suspension bridges and owed a wire-making business.  He gave his son and extraordinary education in bridge engineering for the time, and before beginning work on the Brooklyn Bridge he served as an officer in the Union Army during the Civil War.

 

Why should a cutting-edge STEM student read about a bridge that is almost 130 years old?  It’s because we still use and rely on very successful, centuries old technologies.  Improving and rebuilding our infrastructure will be an important part of our economy.  As recently as 2010, New York City and the federal government committed $500 million to repair and repaint the Brooklyn Bridge.

 

The Essential Engineer: Why Science Alone Will Not Solve Our Global Problems by Henry Petroski

STEM lumps together science, technology, engineering, and mathematics.  Is there a difference between science and engineering?  Is it important?

 

Henry Petroski, a professor of civil engineering and history and author of The Essential Engineer, believes there is an important difference.  At heart, science is about increasing knowledge.  Engineering is about invention.  Of course, new knowledge makes new invention possible.  Just as often, though, engineering runs ahead of science.  Sometimes science didn’t advance until someone invented the instruments to conduct new observations and experiments.  The invention of the microscope made possible the science of microbiology.  Steam engines were built and greatly improved before we had a modern scientific understanding of thermodynamics.  In fact, thermodynamics was to a large extent born out of desire to understand steam engines. In this sense, it is an engineering science (study of manmade things) as much as a natural science (study of natural things) or branch of physics.

 

Petroski’s focus in the book is the importance of engineering to policymaking, where it is often overshadowed by science.  Policy, science, and engineering play off of each other a lot.  Most of my career as an engineer has been related to government, policy, and regulatory compliance.

 

The Ghost Map: The Story of London’s Most Terrifying Epidemic—and How It Changed Science, Cities, and the Modern World by Steven Johnson

The Ghost Map by science writer Steven Johnson is the story of the birth of epidemiology.  Epidemiology is a medical science that uses statistics to help us understand how diseases operate in a population.  Using various statistical and geographic tools, long before we had computers and GIS, physician John Snow demonstrated that cholera, once a recurring plague that wiped out hundreds of thousands of people in some outbreaks, was a waterborne disease.  This understanding, initially met with much skepticism, allowed officials to intervene to prevent the spread of the disease.  For those who say of their math classes, “I’ll never us this,” here is a case where math (and science and policy) were used to make a great difference.

 

Undaunted Courage: Meriwether Lewis, Thomas Jefferson, and the Opening of the American West by Stephen Ambrose

It is not much publicized today that the Lewis and Clark expedition of 1804 to 1806 had a partly scientific mission.  Captains Lewis and Clark were charges with bringing back samples of the flora, fauna, and culture of the western territories.  It was also hoped that they would find a water passage to the Pacific Ocean.  In Undaunted Courage, Stephen Ambrose writes about the scientific mission as well as the policy, diplomacy, and commercial hopes the expedition carried.

 

Of course, what attracts most people to the Lewis and Clark expedition is that it was a great adventure.  There is a place in STEM fields for thoughtful adventurers and explorers. 

 

Buried Alive: The Terrifying History of Our Most Primal Fear by Jan Bondeson

A list like this deserves something strange, creepy, and more fun than you care to admit.  Right now, thousands of very young future STEM workers are catching bugs and snakes, breaking their toys to see what is inside, or staring into space with a weird expression of vacancy and concentration.

 

Jan Bondeson’s Buried Alive is not a morbid book.  It is sometimes humorous, especially in consideration of topic.  From a STEM point of view, Bondeson shows how knowledge accumulates over time.  The fears and activities of our forefathers may seem strange to us, but they sometimes made sense in light of what they knew.  Buried Alive doesn’t simply play off our fascination with the grotesque and death, though the book might not have been written if we lacked that fascination, I think it reminds us to approach our ancestors with a touch of grace and humility.  Maybe our progeny will show us the same courtesy.

 

If you’re looking for something for a younger student, check out this post→ from Joanne Loves Science or these recommendations→ from STEM Friday.  By the way, I also write about engineering, infrastructure and the environment at Infrastructure Watch.

Skywalk Memorial Close to Fundraising Goal, Construction of New Design Anticipated

When I was an undergraduate engineering student about 20 years ago, one of the events covered in the engineering ethics class I took was the 1981 collapse of the skywalk at the Hyatt Regency in Kansas City, Missouri.  Even 31 years after the collapse, the 114 people who were killed are remembered.

A nonprofit foundation was formed to create a memorial to the victims of the collapse.  It is now only $150,000 from having enough to start construction of the memorial.  It has also chosen a design.

You can visit the Skywalk Memorial Foundation at www.skywalkfoundation.org.

Book Review: Blue Revolution by Cynthia Barnett

Barnett, Cynthia.  Blue Revolution: Unmaking America’s Water Crisis.  Boston: Beacon Press, 2011.

America has a problem.  We’re a thirsty nation.  Actually, it’s more like we’re addicted to water, abusing it.  We subsidize its use on a grand scale in industries that use it inefficiently, even wastefully, and in locations where it is naturally hard to come by.  We allocate it based on facts that are no longer true, and were doubtful or changing even as we made our policies.  In our sometimes blind enthusiasm, we overreached and now we are mire in unintended consequences.  To top it off, we rarely change our ways until a crisis is already upon us.

Cynthia Barnett describes these problems in her book Blue Revolution.  She also looks around the country and the world for solutions.  Her essential solution is a water ethic.

Atnone time, people were intimately connected to water.  Farmers watched for rain.  Children fetched pails of it from the stream or worked a pump handle.  Communities were built around watermills where people brought in grain or carried away flour. 

Of course, water is no less essential to modern life.  We depend on it for drinking, cleaning, sanitation and green lawns.  It is essential or the energy that light and cools our homes and powers our computers.  The abundance of food in our groceries stores is partly a testament to the abundance of water used to irrigate fields that don’t get enough rainfall for the crops we grow.

What is different is the way we view water.  For most of us it is cheap, nearly free in comparison to other utilities and services we use in our homes.   We can get as much as we want whenever we want by opening a valve.  Water is something we hold back with dams, divert with canals, and pump through pipes.  It bends to our will—except when it doesn’t.

Our water policies and technologies have often had unintended consequences.  We turned deserts into productive fields, but much of the water is lost to evaporation.  We moved water great distances to supply cities, but it encouraged profligacy that threatens those distant, expensive supplies.  Dams that were engineering marvels may soon stand at the ends of empty lakes.

Sure, changes in technology and policy are needed to stop, and hopefully reverse, these problems.  Barnett doesn’t stop there.  Our approach to water arises from the way we value it, think about it, and relate to it.  Our present state came from valuing water little, thinking about it little unless it was our job, and relating to it little except for those who intensely depended on a highly subsidized supply.

The water ethic Barnett proposes would value water, both in the sense of personal appreciation and economic cost and opportunity.  It would seek the best use of the water we have, especially what is locally available.  It creates opportunities for people to contact water and understand where it comes from and how it is affected by use.  It is something that spreads organically from person to person, neighborhood to neighborhood, business to business, and city to city.

It is an ethic that is within reach, too.  Barnett describes how places that have long had extreme relationships with extreme water environments, like the Netherlands, Singapore and Australia, have changed their relationship with water.  These are not just policy shifts, they are cultural changes.  Even in the United States, there are places where a new water ethic is taking hold and people understand how important and fragile water is.

Russell E. Train, Conservationist & Environmental Policy Pioneer, Died

Russell E. Train died yesterday, Sept. 17, 2012.  Train was one of the primary proponents of the National Environmental Policy Act of 1969.  Richard Nixon, whom he previously served as Under Secretary of Interior, appointed him as the first chair of the Council on Environmental Quality; he served in that post from 1969 to 1977.  Gerald Ford appointed him Administrator of the Environmental Protection Agency.

Train became a leader in the World Wildlife Fund in 1978.  Train had previously worked in conservation organizations.  He became president of the Conservation Foundation in 1965 and in 1961 he founded the African Wildlife Leadership Foundation.  Under his leadership, the World Wildlife Fund expanded its role to preserving habitat as well as advocating for wildlife.

Infrastructure Watch (or at least a certain contributor) appreciates that Train was a collector of books, particularly those related to wildlife and conservation.  The Smithsonian Institution acquired his collection of Africana in 2004.

Book Review: The Big Roads by Earls Swift

Swift, Earl.  The Big Roads: The Untold Story of the Engineers, Visionaries, and Trailblazers Who Created the American Superhighways.  Boston: Houghton Mifflin Harcourt, 2011.

The American interstate system is often thought to be a product of the Eisenhower administration.  It’s named for him.  However, the nearly 47,000 miles of interstate were conceived largely before Eisenhower’s presidency.  Even as he observed the Army’s 62-day, cross-country convoy of 1919, engineers were laying the political and technical foundations of national highways.  Earl Swift tells this longer history of the interstates in The Big Roads.

When Americans began calling for better roads, the typical road was mud.  The loudest calls for better roads at the beginning of the 20^th Century were cyclists, especially the colorful Carl Fisher.  Fisher’s most famous work is the Indianapolis Speedway, where a popular 500-mile race continues to be run.  His promotion of the Lincoln Highway, the first coast-to-coast highway (at least on paper), provided an important antecedent to the interstates.

The Lincoln Highway Association operated on a system that informed later highway development.  Rather than build a huge new highway, it selected existing roads for improvement, joining them together in a highway.  New roads were built only if necessary.  The association, a private organization that raised private funds for road improvement and route promotion, was a model for later systems in another way.  The Lincoln Highway was built and improved in pieces by a number of local and state agencies.  The association provided a route, coordination, promotion, encouragement, and sometimes funding, but the road improvements were mostly local works.

Thomas MacDonald, an Iowa highway engineer, was using a similar model as he worked for that state.  He worked with city and county road departments to coordinate improvements leading to a statewide system of decent roads.  When he became director of the Office of Public Roads, he brought this model to the federal highway program, institutionalizing it in the Federal Aid system that began in 1916.

Of course, the U.S. highways that developed under this system were not like modern interstates.  They were open to anyone along them.  In rural areas, they might have been and often still are long ribbons of pavement crossed by the occasional farm road.  In cities, they became crowded with business, especially restaurants and gas stations, that slowed traffic to a crawl.  This problems gave rise to the concept of a limited-access highway, first proposed by Benton MacKaye, the conservationist who conceived the Appalachian Trail.

MacDonald and his engineers began working the concept.  His office produced a report, authored primarily by Hubert Sinclair Fairbanks, that laid out most of the current interstate system in 1938.  Fairbanks supported that idea that better roads might solve problems related to slums and blight in cities.  The recommendations of this report and a follow-up commission were largely implemented in law in 1944, when the term “interstate” first appeared in legislation.

The plans for an interstate system languished during World War II and the years immediately following.  Eisenhower comes into the picture at this time because he strongly supported funding for the interstate system.

Highway engineers saw themselves as providing a good and giving the people what they wanted.  Along the way, as Fairbanks suggested, they could clean up the cities.  As they began to implement their plans in earnest, opposition arose.

Swift gives particular attention to two interstate opponents.  Critic Lewis Mumford provided the intellectual and philosophical foundation for the Freeway Revolt.  Joe Wiles, a black professional and veteran, organized opposition to Interstate 70 in Baltimore which resulted in changes to the plan and help unite the white and black communities in that city.  The federal and state governments began to take seriously the possibility that interstates could have a negative impact on the communities near them

The intestate system, finally completed in the 1990s, is the largest public works project in history.  Now that it is built, it needs to be maintained.  It will be expensive: $225 billion a year for the next 50 years to keep it in good shape.  That is more than twice what we’re spending.  In addition, improved fuel efficiency and reduced driving prompted by the economic downturn has reduced gas tax revenues for the Highway Trust Fund.  In the near future, we may need to find new ways to pay for maintaining our transportation marvel.
