More Accurate Measurements Reveal Previously Undetected Anomalies

(p. 69) This is a standard pattern in the history of science: when tools for measuring increase their precision by orders of magnitude, new paradigms often emerge, because the newfound accuracy reveals anomalies that had gone undetected. One of the crucial benefits of increasing the accuracy of scales is that it suddenly became possible to measure things that had almost no weight. Black’s discovery of fixed air, and its perplexing mixture with common air, would have been impossible without the state-of-the-art scales he employed in his experiments. The whole inquiry had begun when Black heated a quantity of white magnesia, and discovered that it lost a minuscule amount of weight in the process–a difference that would have been imperceptible using older scales. The shift in weight suggested that something was escaping from the magnesia into the air. By then running comparable experiments, heating a wide array of substances, Black was able to accurately determine the weight of carbon dioxide, and consequently prove the existence of the gas. It weighs, therefore it is.

Magdeburg Sphere Let Scientists “See” the Vacuum

(p. 68) When we think of technological advances powering scientific discovery, the image that conventionally comes to mind is a specifically visual one: tools that expand the range of our vision, that let us literally see the object of study with new clarity, or peer into new levels of the very distant, the very small. Think of the impact that the telescope had on early physics, or the microscope on bacteriology. But new ways of seeing are not always crucial to discovery. The air pump didn’t allow you to see the vacuum, because of course there was nothing to see: but it did allow you to see it indirectly, in the force that held the Magdeburg Sphere together despite all that horsepower.

Most Great Inventors Were Blessed with Leisure Time

(p. 49) With his wife running the household and tending to their four-year-old daughter, Sally, Priestley simply had more time on his hands to explore, invent, and write. Priestley was retracing a pattern that Franklin had originally carved two decades before, when he handed over day-to-day operation of his printing business to his foreman, David Hall, in 1748 and then spent the next three years transforming the science of electricity. Necessity may be the mother of invention, but most of the great inventors were blessed with something else: leisure time.

World Astonished that an American Tradesman Tamed Lightning

(p. 24) Within five years of his speculative note to Collinson, lightning rods had become a common sight on church steeples throughout Europe and America. Franklin’s biographer Carl Van Doren aptly describes the astonishment that greeted these events around the world: “A man in Philadelphia in America, bred a tradesman, remote from the learned world, had hit upon a secret which enabled him, and other men, to catch and tame the lightning, so dread that it was still mythological.”

Steven Johnson’s The Invention of Air

Source of book image: http://stevenberlinjohnson.typepad.com/photos/uncategorized/2008/09/10/invention_final_81908.jpg

Steven Johnson’s The Ghost Map, about the determined entrepreneurial detective work that uncovered the cause of cholera, is one of my all-time favorite books, so I am now in the mode of reading everything else that Steven Johnson has written, or will write.
The most recent book, The Invention of Air, is not as spectacular as The Ghost Map, but is well-written on a thought-provoking topic. It focuses on Joseph Priestley’s role in the American Revolution. Priestley is best known as an early chemist, but Johnson paints him as a poly-math whose science was of a piece with his philosophy, politics and his religion.
Johnson’s broader point is that for many of the founding fathers, science was not a compartment of their lives, but part of the whole cloth (hey, it’s my blog, so I can mix as many metaphors as I want to).
And the neat bottom line is that Priestley’s method of science (and polity) is the same broadly empirical/experimental/entrepreneurial method that usually leads to truth and progress.
Along the way, Johnson makes many amusing and thought-provoking observations, such as the paragraphs devoted to his coffee-house theory of the enlightenment. (You see, coffee makes for clearer thinking than beer.)

Congress Blocked Navy’s Grab of Radio Airwaves

Source of book image: online version of the WSJ review quoted and cited below.

(p. A15) “Hello Everybody!” is at its most valuable when it chronicles the early regulatory fights over the new medium. In the days after World War I, the Navy pushed hard for control of all “wireless” facilities, which were then used primarily used for point-to-point messaging. If the admirals had succeeded in that grab, which was blocked by Congress, the advent of broadcast radio would no doubt have been delayed and the industry might have developed more along the lines of European radio, with a great deal of government control.

Inventors Move from Declining Industries to New, Expanding Industries

Petra Moser’s comments (see below) about inventors applying similar ideas to different industries seem complementary to Burke’s emphasis on the importance of serendipitous “connections.” An inventor exposing herself to many industries’ problems and products, would be more likely to see additional applications for inventions originally developed for another industry.

(p. 3) By some logic, there is no earthly reason why bicycles should still exist.

They are a quaint, 19th-century invention, originally designed to get someone from point A to point B. Today there are much faster, far less labor-intensive modes of transportation. And yet hopeful children still beg for them for Christmas, healthful adults still ride them to work, and daring teenagers still vault them down courthouse steps. The bicycle industry has faced its share of disruptive technologies, and it has repeatedly risen from the ashes.
. . .
“Much of the history of the ‘American system of manufacturing’ is the story of inventors moving from a declining industry to a new expanding industry,” says Petra Moser, an economic historian at Stanford who studies innovation. “Inventors take their skills with them.”
Gun makers learned to make revolvers with interchangeable parts in the mid-19th century, Ms. Moser says. Then those companies (and some former employees, striking out on their own) applied those techniques to sewing machines when demand for guns slackened. Later, sewing machine manufacturers began making woodworking machinery, bicycles, cars and finally trucks.
. . .
Meanwhile, we’ve already seen some of the “destruction” half of Joseph Schumpeter’s famous “creative destruction” paradigm, with many newspapers cutting staff and other production costs. Unfortunately for newspapers, historians say, the survivors in previous industries facing major technological challenges were usually individual companies that adapted, rather than an entire industry. So a bigger shakeout may yet come.
But perhaps the destruction will lead to more creativity. Perhaps the people we now know as journalists — or, for that matter, autoworkers — will find ways to innovate elsewhere, just as, over a century ago, gun makers laid down their weapons and broke out the needle and thread. That is, after all, the American creative legacy: making innovation seem as easy as, well, riding a bike.

Older Technologies Sometimes Regain the Lead Over Newer Ones

(p. R8) Innovation occurs almost constantly at the level of design and components, absorbing companies’ attention as they look for ways to best their competitors. Platform innovations are less frequent. But when they do occur, they have the potential to transform markets, not just give an edge to one competitor.

One great danger to companies is to be so immersed in design and component innovation that they miss out on a platform innovation. For example, while Sony Corp. focused in the 1990s on improving its CRT television sets, a market it dominated, rival Samsung Electronics Co. invested heavily in flat-screen LCD TVs. As the market for LCD TVs grew, Sony fell behind its rivals and ended up entering into a joint venture with Samsung to build liquid-crystal displays.

Innovation’s Messy Paths
Another mistake to avoid is to assume that all technologies follow a standard progression.
The conventional wisdom is that the performance of any technology is initially low, then improves rapidly after some breakthrough, and ultimately levels out in maturity. A new technology’s performance supposedly starts below that of the established technology, surpasses it after the breakthrough is achieved, and then remains superior until the next big thing comes along. Literature on the subject has encouraged managers to embrace a new technology once it begins to show rapid improvement, and to abandon the old technology because it is destined to become obsolete.
However, our analysis of several markets shows that technological evolution is much messier than this simple pattern. For instance, new technologies sometimes enter the market with better performance than the existing technology, only to fall behind at some point before later regaining the lead. That’s the case in the market for external lighting. When gas-discharge lighting, which is used in fluorescent tubes, was introduced around 1930, it was brighter per watt than the existing arc-discharge lighting, which is used in many street lamps, and it maintained that superiority for some 40 years, until improvements in arc-discharge lighting made it the brightest per watt again. Then, in 1980, gas discharge made its biggest jump in performance so far, again surpassing arc discharge in brightness per watt. Both technologies have gone through several long periods of stagnation followed by sharp improvements in performance.
When one technology is growing rapidly, it’s easy to get caught up in the hype and overinvest in it. However, the unpredictability and impermanence that we found in this and other markets suggests that companies should consider investing in, or at least monitoring, a portfolio of technologies, so they aren’t blindsided by a sudden improvement in one or another.
Consider the competition between ink-jet and laser technology in the printer market. When the two technologies were introduced in the mid-1980s, laser was far superior to ink-jet in resolution. Ink-jet quickly caught up, but didn’t surpass laser’s resolution. Then, in the mid-1990s, laser again took a significant lead. But ink-jet surpassed laser in resolution in 1997 and has maintained that edge. All the while, printer maker Hewlett-Packard Co. continued to sell both ink-jet and laser printers, putting itself in the best position to succeed in a shifting market

“In Spite of the Economic Crisis and Unemployment . . . Civilization’s Progress is Going Faster and Faster”

The Palace of Discovery mentioned in the passage below was a part of the 1937 Paris Exposition.

(p. 206) The mastermind behind the Palace of Discovery, French Nobel Prize laureate Jean Perrin, wrote, “In spite of the wars and the revolutions, in spite of the economic crisis and unemployment, through our worries and anxieties, but also through our hopes, civilization’s progress is going faster and faster, thanks to ever-more flexible and efficient techniques, to farther- and farther-reaching lengths. . . . Almost all of them have appeared in less than a century, and have developed or applied inventions now known by all, which seem to have fulfilled or even passed the desires expressed in our old fairy tales.”

The Palace of Discovery: “They Came for Wonder and Hope”

The Palace of Discovery (aka Palais de la Decouverte) in Paris. Source of photo: http://www.flickr.com/photos/paris2e/2524827592/

Near the beginning of World War II, the 1937 Palace of Discovery in Paris, was a popular source of hope for the future:

(p. 206) An unexpectedly popular draw at the exposition was a relatively small hall hidden away behind the Grand Palais. The Palace of Discovery, as it was called, attracted more than 2 million visitors, five times the number that visited the modern art exhibit. They came for wonder and hope. The wonder was provided by exhibits including a huge electrostatic generator, like something from Dr. Frankenstein’s lab, two enormous metal spheres thirteen feet apart, across which a 5-million-volt current threw a hissing, crackling bolt of electricity. The hope came from the very nature of science itself. Designed by a group of liberal French researchers, the Palace of Discovery was intended to be more a “people’s university” than a stuffy museum, a place to hear inspiring lectures on the latest wonders of science, messages abut technological confidence and progress for the peoples of the world.

In Geology, Economic Growth Caused Scientific Progress

(p. 130) . . . , the major problem inhibiting England’s industrial development was the state of the roads. So the introduction of waterborne transportation on the new canals triggered massive economic expansion because these waterways transported coal (and other raw materials) much faster and cheaper than by packhorse or wagon. In 1793 a surveyor called William Smith was taking the first measurements in preparation for a canal that was to be built in the English county of Somerset, when he noticed something odd. (p. 131) Certain types of rock seemed to lie in levels that reappeared, from time to time, as the rock layer dipped below the surface and then re-emerged across a stretch of countryside. During a journey to the north of England (to collect more information about canal-construction techniques), Smith saw this phenomenon happening everywhere. There were obviously regular layers of rock beneath the surface which were revealed as strata where a cliff face of a valley cut into them. In 1796 Smith discovered that the same strata always had the same fossils embedded in them. In 1815, after ten years of work, he compiled all that he had learned about stratification in the first proper colored geological map, showing twenty-one sedimentary layers. Smith’s map galvanized the world of fossil-hunting.
