In the United States “Innovation” Became a Positive Word

(p. 198) “All advances in science were proscribed as innovations.” Jefferson is using the older, negative sense of the word “innovation” here: a new development that threatened the existing order in a detrimental way. (The change in the valence of the word over the next century is one measure of society’s shifting relationship to progress.) But that regressive age was now over, and Priestley–the most forward-thinking mind of his generation–could now consider himself fully at home:

Our countrymen have recovered from the alarm into which art and industry had thrown them: science and honesty are replaced on their high ground, and you, my dear Sir, as their great apostle, are on its pinnacle. It is with heartfelt satisfaction that in the first moments of my public action, I can hail you with welcome to our land, tender to you the homage of its respect and esteem, cover you under the protection of those laws which were made for the wise and good like you, and disdain the legitimacy of that libel on legislation which under the form of a law was for some time placed among them.

Perhaps inspired by the legendary optimism of Priestley himself, Jefferson then added some of the most stirringly hopeful words that he ever put to paper:

(p. 199) As the storm is now subsiding, and the horizon becoming serene, it is pleasant to consider the phenomenon with attention. We can no longer say there is nothing new under the sun. For this whole chapter in the history of man is new. The great extent of our Republic is new. Its sparse habitation is new. The mighty wave of public opinion which has rolled over it is new. But the most pleasing novelty is, it’s so quietly subsiding over such an extent of surface to its true level again. The order and good sense displayed in this recovery from delusion, and in the momentous crisis which lately arose, really bespeak a strength of character in our nation which augurs well for the duration of our Republic; and I am much better satisfied now of it’s stability than I was before it was tried.

Bacon Died Experimenting and Hegel Died Contradicting Himself

(p. C32) The philosopher Francis Bacon, that great champion of the empirical method, died of his own philosophy: in an effort to observe the effects of refrigeration, on a freezing cold day he stuffed a chicken with snow and caught pneumonia.

As a philosopher dies, so he has lived and believed. And from the manner of his dying we can understand his thinking, or so the philosopher Simon Critchley seems to be saying in his cheekily titled “Book of Dead Philosophers.”
. . .
Mr. Critchley recounts that Voltaire, after decades of denouncing the Roman Catholic Church, announced on his deathbed that he wanted to die a Catholic. But the shocked parish priest kept asking him, “Do you believe in the divinity of Christ?” Voltaire begged, “In the name of God, Monsieur, don’t speak to me any more of that man and let me die in peace.”
Hegel, who, as much as any philosopher, Mr. Critchley says, saw philosophy as an abstraction, while he was dying of cholera, moaned, “Only one man ever understood me … and he didn’t understand me.”

An Environment Where Long-Term Hunches Could Thrive

An environment in which long-term hunches can be pursued, is important not just to science and invention. I speculate that it is also important to entrepreneurship.

(p. 74) If great ideas usually arrive in fragments, a partial cluster of neurons, then part of the secret to having great ideas lies in creating a working environment where those fragments are nurtured and sustained over time. This obviously poses some difficulty in modern work environments, with deadlines and quarterly reports and annual job reviews. (The typical middle manager doesn’t respond favorably to news that an employee has a hunch about something that probably won’t see results for twenty years.) But Priestley had created an environment for himself where those long-term hunches could thrive with almost no pressure, and his habit of simultaneously writing multiple documents (on multiple topics) kept the fragments alive in his mind over the decades. In the final pages of his memoirs, he mentions a lifelong habit of writing down “as soon as possible, every thing I wish not to forget.”

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.

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.”

Environmentalists Abandon Science

In honor of “Earth Day,” some thoughtful comments by a co-founder of Greenpeace:

(p. A23) In 1971 an environmental and antiwar ethic was taking root in Canada, and I chose to participate. As I completed a Ph.D. in ecology, I combined my science background with the strong media skills of my colleagues. In keeping with our pacifist views, we started Greenpeace.
But I later learned that the environmental movement is not always guided by science. As we celebrate Earth Day today, this is a good lesson to keep in mind.
At first, many of the causes we championed, such as opposition to nuclear testing and protection of whales, stemmed from our scientific knowledge of nuclear physics and marine biology. But after six years as one of five directors of Greenpeace International, I observed that none of my fellow directors had any formal science education. They were either political activists or environmental entrepreneurs. Ultimately, a trend toward abandoning scientific objectivity in favor of political agendas forced me to leave Greenpeace in 1986.
The breaking point was a Greenpeace decision to support a world-wide ban on chlorine. Science shows that adding chlorine to drinking water was the biggest advance in the history of public health, virtually eradicating water-borne diseases such as cholera. And the majority of our pharmaceuticals are based on chlorine chemistry. Simply put, chlorine is essential for our health.
My former colleagues ignored science and supported the ban, forcing my departure. Despite science concluding no known health risks – and ample benefits – from chlorine in drinking water, Greenpeace and other environmental groups have opposed its use for more than 20 years.

An Intellectual Collaboration Beyond the Grave

There is something touchingly noble in this:

(p. 11) There is no direct evidence in the historical record, but it is entirely probable that it was the waterspout sighting that sent Priestley off on his quest to measure the temperature of the sea, trying to marshal supporting evidence for a passing conjecture his friend had made a decade before. Franklin had been dead for nearly four years, but their intellectual collaboration continued, undeterred by war, distance, even death.

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.)

Atmospheric Carbon Dioxide that is Probably Not Caused by Human Activity

“This artist’s concept shows a cloudy Jupiter-like planet that orbits very close to its fiery hot star.” Source of caption and image: online version of the NYT article quoted and cited below.

(p. A31) Astronomers testing techniques to search for extraterrestrial life have detected carbon dioxide in the atmosphere of a planet 63 light-years away.

This carbon dioxide, though, is certainly not coming from plants or automobiles. The planet, HD 189733b, is far too large (about the mass of the Jupiter) and too hot (1,700 degrees Fahrenheit) for any possibility of life.

“Little Risk the Ice Sheet Will Collapse”

“To probe the underside of Greenland’s glaciers, NASA researcher Alberto Behar released 90 specially tagged rubber ducks into a fissure of the Jakobshavn Isbrae glacier in Greenland, tracking their progress along underground melt-water streams.” Source of caption: typed from print version of the WSJ article quoted and cited below. Source of photo: edited screen capture from the online version of the WSJ article quoted and cited below.

(p. A13) As researchers learn more about the mechanics of Greenland’s glaciers, they are becoming convinced that, by itself, the sub-surface water slide created by so much melting ice may be a short-lived seasonal effect, says University of Washington polar scientist Ian Joughin. The glaciers speed up in the summer but slow down in the fall. If that’s true, there may be little risk the ice sheet will collapse as some scientists recently feared — at least not for the foreseeable future.
