I’m a little hesitant to include Jed Buchwald’s Rise of the Wave Theory of Light (1989) in my physics canon, not because of any flaws in the book—it very nicely accomplishes what it sets out to do—but because it’s so focused on its argument concerning the rise of the wave theory. This means it focuses tightly on people directly involved with the rise of the wave theory, notably Augustin Jean Fresnel, and leaves some other important figures, Thomas Young for example, at the margins.
Since we haven’t done the Canonical series in a while, it’ll be useful to refresh the point of the exercise. It is not to offer a “best of” in history of science writing or argumentation; rather it is books one can concentrate on to get a good, sophisticated overview of what happened in history. Thus, reading Buchwald’s book, one should be aware that one is getting an explanation for the rise of the wave theory, not a history of the wave “idea”, or a tour of early 19th-century optics, which would be most useful from the “Canonical” perspective. But, seeing as I know of no other book that covers the subject in a detailed and sophisticated way, canonical Rise of the Wave Theory of Light shall be. We can always go back and replace it, or supplement it with a journal article or two, at a later date.
The bulk of the action in the book takes place between 1810 and 1830, which, readers should be aware, stretches across a fault line in the history of physics (i.e., read Warwick and early chapters of Jungnickel & McCormmach first; and (more…)
Primer: Linus Pauling February 25, 2009

In recognition of the 108th anniversary of Linus Pauling’s birth (kind of our poor man’s response to the Darwin’s 200th hoopla!), our neighbors at the Pauling Blog have sent us over a really excellent post on their namesake, which will be appearing on their site in slightly modified form on Friday.
Linus Pauling was born in Portland, Oregon on February 28, 1901, meaning that this coming Saturday will mark the 108th anniversary of his birth. (He died on August 19, 1994 at the age of 93)
One of the Oregon State University Libraries Special Collections’ annual habits has been to reflect back upon Pauling’s life around the time of his birthday anniversary, usually by highlighting his activities 100, 75, 50 and 25 years ago.
Looking back in segments of twenty-five years is admittedly rather an arbitrary observance, but it can oftentimes prove to be very revealing. By choosing to study the effectively-random dates of, in this instance, 1909, 1934, 1959 and 1984, one is compelled to sample a broad period of time in Pauling’s life and, in the process, gain a sense of his remarkably-wide variety of interests. It is our belief that, as much as anything else, these broad horizons define Pauling’s legacy.

Philosophy and the History of Science February 24, 2009
Posted by Will Thomas in Methods.add a comment
In my earlier “pocket history” of the relationship between philosophy, sociology, and history, I noted a few key points:
- Philosophers tended to use the history of science as a way to develop the philosophy of science.
- Sociologists noticed that there was much in the history of science that did not fit philosophy-based history.
- Sociological theories were insufficient to explain the exact path of the history of science, leading some sociologists to develop sociological epistemologies.
What should already be clear is that the history of science cannot work without interrelated philosophical and sociological elements. You don’t really know you know anything unless you can get someone else to agree with you, but you’ll have a harder time commanding agreement unless you can demonstrate that you really do know something.
What is not, I think, entirely clear is how philosophy and sociology combine to create powerful history. Historians have responded to the sociological insights by focusing intently on day-to-day practices. Experimental instrumentation, representation of objects, public lectures all became important parts of the historical examination of (more…)
Good Work and Good History February 21, 2009

All of the methodological introspection that takes place on this site is done with an eye toward arriving at a sympathetic, charitable, and critical understanding of the way today’s history of science profession works, and to figure out what it does well and also what it does less well.
To this point, much of this introspection has involved intuiting a professional mentality—an understanding of what individual scholars feel they are contributing to the profession as a whole. I have noted that the way scholars frame and justify their work seems to operate according to an “epistemic imperative”, the idea that what we are saying contributes to a sociological and philosophical understanding of the nature of both elite and public knowledge (thus, the “epistemological problematic“). Exactly how work is supposed to add up into this understanding is rarely (if ever) made clear (a point also made by Peter Galison in his 10 Questions—I’m not just making this stuff up!).
Lately on this site, we have been exploring other aspects of this mentality, assuming an individualistic rather than a communitarian sensibility. Here “the “epistemic imperative” becomes less of a serious suggestion for application of the (more…)

This post is a sequel, of sorts, to my previous post on the “100,000 garages” rhetorical device, and, more directly, to my Hump-Day History post on Fred Terman. It is also an extension of yesterday’s post on the AIP’s History of Physicists in Industry project, where I pointed out that analyses of firm behavior at the project level would be a useful thing for historians to do. Of course, there are cases where this has already been done, at least to an extent, with great success, as in the case of Silicon Valley vacuum tube and integrated circuit manufacturing firms.

Between the 1930s and the 1970s, the region around Palo Alto, California, just south of San Francisco, grew into a center for electronics innovation and manufacture, challenging the domination of the electronics industry by firms such as General Electric, RCA, Western Electric, and Westinghouse.

In light of my recent discussion of Steven Shapin’s Scientific Life (Part 1 and Part 2), I thought it might be useful to promote something rather different on pretty much the same topic: the project report just released by my employers at the AIP History Center on their multi-year “History of Physicists in Industry” project, assembled through the efforts of Joe Anderson, who runs the Niels Bohr Library and Archives, and Orville Butler, who has the office next door to mine. Some early work on the project was done by Tom Lassman, who is now at the Air and Space Museum downtown in DC. Click on the image to access the report in .pdf form.
The project’s aim was to survey industrial researchers and research administrators with the goal of finding out what historical records industries preserve, and how; as well as to undertake a preliminary survey of industrial research activities and attitudes since World War II.
I would describe the report as an empirical extraction of “trends” from interview data. Insofar as it analyzes commentary, it is actually quite similar to Shapin’s work, (more…)
Charitable, Skeptical, and Critical Readings February 14, 2009
Posted by Will Thomas in Methods.7 comments
I would like to consider the methodological problem of how historians read sources in terms of a tripartite taxonomy of reading attitudes: charitable, skeptical, and critical. I take a critical reading to be a combined form of charitable and skeptical readings. For some background, see the brief conversation that developed over at Time to Eat the Dogs.
The prerogative of the historian is to offer a critique of past events, which should be distinguished from criticism. A critique offers an articulation and analysis of events; it may be accompanied by a criticism, but its primary concern is with arriving at an interpretation which renders the past coherent. History is a science and not literature insofar as some critiques can render history more coherent than others. Interpretations of coherence are subject to agreement based on an assessment of:
- the physical reality of events of the past;
- the psychological motivations of actors; and, most provisionally…
- an account of the prerequisites and causes of events.
I take (1) to be reasonably unproblematic, and (3) to be extremely problematic—if ultimately most rewarding—requiring an extensive, complicated, and highly debatable taxonomy of historical “trends” as well as some physical, economic, and sociological theory of how “trends” unfold.
Concerning the possibility of agreement concerning either (1) or (3), historians must deal with the historical record, (more…)
Primer: Augustin Jean Fresnel February 11, 2009

Augustin Jean Fresnel (1788-1827) was a French engineer and physicist who was a key figure in the move from an “emission” theory of light to a “wave” theory of light in the optical physics of the early-nineteenth century. Where a “ray” of light was generally taken to be a physical, if imperceptible, thing, which could (in theory) be counted, the new wave theory took a ray to be only a geometrical construct connecting a luminous source with a point on a wave front as it traveled through an ethereal medium (ether wave propagation!).
Fresnel was the son of an architect who, having a penchant for mathematics, began training at the new Ecole Polytechnique in Paris at the age of seventeen, where he received extensive instruction in methods of mathematical analysis, chemistry, and physics—an education that gave him both a background in natural philosophical conceptualizations as well as in practical technique.
Eager to make a “discovery” of any sort, he bounced between fields early on. After he left the Ecole in 1806, he worked as an engineer with the elite Corps des Ponts et Chausées (Bridges and Roadworks Corps) for three years, and in 1810 he (more…)
The Ultimate in Empiricism February 10, 2009
Posted by Will Thomas in Uncategorized.add a comment
For those who don’t check in with the Pauling Blog, the Oregon State Special Collections has launched Linus Pauling Day-by-Day.
As our regular readers have probably gathered, I’m not very keen on the “gallery of practices” mode of historical scholarship, wherein the theory-trained scholar dives into the archive and just starts pointing out all the epistemological assumptions and practices, cultural contexts, and negotiated knowledge claims they can find in there so as to add another image to the gallery. To consolidate gains and to synthesize history, it is necessary to gain a wide empirical knowledge of the historical terrain—a point I hope to discuss much further in the future.
Pauling Day-by-Day represents an ultimate extension of empiricism. I’ve often thought as I’ve attempted to make sense of a historical terrain that it would be very nice if I could just throw all the correspondence and memoranda and everything into chronological order to make better sense of it. Pauling Day-by-Day does precisely this.
Scholars who work in the biography industry will be familiar with similar efforts to figure out what Charles Darwin or Albert Einstein was doing on (more…)
Localized Historiography February 9, 2009
Posted by Will Thomas in Methods.add a comment
I think Christopher and I are slightly out-of-sync concerning the terminology of historiographic “atavism” (which is his very useful term). An atavism is a degradation. If we take the qualities of a historiography to be simply the contents of the historiographical archive, then atavism is impossible, since the archive cannot be destroyed (one would hope). However, an archive is only as good as an understanding of its contents, meaning that if new historical work consistently fails to engage with its insights, the historiography is degraded simply through lack of use.
Christopher identifies the qualities of writing that he characterizes as “atavistic” scholarship. My argument would be that certain styles of writing are more apt to risk atavism than others in much the way he describes, but that atavism itself can be traced to no single work. It is part of the insidiousness of historiographic atavism that no individual can be held responsible for it.
The lack of accountability is related to the technique of “perspective layering” (more…)
