Negotiating History: Contingency, Canonicity, and Case Studies
Studies in History and Philosophy of Science Part A (2019), (pdf preprint).
Co-authored with Agnes Bolinska; Winner of the 2019 IUHPST Essay Prize in History and Philosophy of Science

Objections to the use of historical case studies for philosophical ends fall into two categories. Methodological objections claim that historical accounts and their uses by philosophers are subject to various biases. We argue that these challenges are not special; they also apply to other epistemic practices. Metaphysical objections, on the other hand, claim that historical case studies are intrinsically unsuited to serve as evidence for philosophical claims, even when carefully constructed and used, and so constitute a distinct class of challenge. We show that attention to what makes for a canonical case can address these problems. A case study is canonical with respect to a particular philosophical aim when the features relevant to that aim provide a reasonably complete causal account of the results of the historical process under investigation. We show how to establish canonicity by evaluating relevant contingencies using two prominent examples from the history of science: Eddington’s confirmation of Einstein’s theory of general relativity using his data from the 1919 eclipse and Watson and Crick’s determination of the structure of DNA.

Mildred Dresselhaus and Solid State Pedagogy at MIT
Annalen der Physik 531 (2019),

When Mildred Spiewak Dresselhaus passed away in February 2017, she left behind an indelible legacy. The “Queen of Carbon,” as she was known, pioneered the physical study of the sixth element well before the keen attention attracted by buckyballs and nanotubes. Her groundwork ensured that when Andre Geim and Konstantin Novoselov isolated and characterized graphene, they were a shoe-in for the Nobel Prize, which they took home in 2010. Dresselhaus also earned renown for her advocacy on behalf of women in science. She was the first woman to be honored with the title of Institute Professor at the Massachusetts Institute of Technology (MIT) and she pioneered leadership roles for women in many of the professional societies and organizations to which she belonged. Here, I focus on a less noted (though no less noteworthy) aspect of her legacy: her influence as a pedagogue.

Cultural Scaffolding and Technological Change: A Preliminary Framework
Beyond the Meme: Development and Structure in Cultural Evolution, Minnesota Studies in Philosophy of Science 20, ed. Alan C. Love and William C. Wimsatt, 425–44. Minneapolis: University of Minnesota Press, 2019 (pdf)

Technology helps us to do new things, or to do old things in new ways. This, at least, is our common understanding and continual hope. Technologies, however, only become useful when guided by human means to human ends and they therefore do not add to our arsenal of abilities in an unproblematic, straightforward manner. Rather they must confront a complex and preexisting set of biological traits and cultural practices before their potentialities and consequences are clear. My goal here is to sketch an account of how technologies interact with the innate and socially supported human capacities to learn and develop, using cultural scaffolding as an interpretive tool.

When Condensed Matter Physics Became King
Physics Today 72, no. 1 (2019): 30–37. (pdf)

Condensed matter physics is huge. This surprises no one who has attended a March meeting of the American Physical Society (APS) or perused the society’s member rolls. The Division of Condensed Matter Physics has been the society’s largest for decades. But the prominence of condensed matter physics, at least by population, is recent. Before World War II, no such field existed. Only in the late 1940s would solid state physics—a precursor to condensed matter physics—emerge as a physical subdiscipline. In his superb book When Physics became King, Iwan Rhys Morus describes how physics itself, practically nonexistent in 1800, grew into the preeminent science by 1900. Condensed matter physics became king in another sense. Its rise reconfigured how the field of physics itself was defined and subcategorized. It reflected new ideas about what it meant to be a physicist and challenges to the cherished ideals upon which the American physics community had been founded.

Prestige Asymmetry in American Physics: Aspirations, Applications, and the Purloined Letter Effect
Science in Context 30, no. 4 (2017): 475–506. (pdf preprint)

Why do similar scientific enterprises garner unequal public approbation? High energy physics attracted considerable attention in the late-twentieth-century United States, whereas condensed matter physics—which occupied the greater proportion of US physicists—remained little known to the public, despite its relevance to ubiquitous consumer technologies. This paper supplements existing accounts of this much remarked-upon prestige asymmetry by showing that popular emphasis on the mundane technological offshoots of condensed matter physics and its focus on human-scale phenomena have rendered it more recondite than its better-known sibling field. News reports about high energy physics emphasize intellectual achievement; reporting on condensed matter physics focuses on technology. And whereas frontier-oriented rhetoric of high energy physics communicates ideals of human potential, discoveries that smack of the mundane highlight human limitations and fail to resonate with the widespread aspirational vision of science—a consequence I call “the purloined letter effect.”

Following the presentation of general resources, journal articles and books are cited for the following topics: conceptual development; institutional and community structure; social, cultural, and political history; and connections between condensed matter physics and technology.

The Peaceful Atom Comes to Campus
Physics Today 69, no. 2 (2016): 40–46. (pdf preprint)

Reflecting on how university research could meet the challenges of the early 1950s, University of Michigan provost James Adams suggested that future historians would consider the heady post–World War II years to be “an age of invincible surmise.” He regarded the era with an optimistic eye. More so than at any point in history, Adams maintained, troves of useful knowledge lay within human grasp; as US society sought to turn that knowledge to its advantage, universities held “a special responsibility for the guardianship of truth.” In the postwar years, the University of Michigan discharged that responsibility through a homegrown program exploring peaceful uses of nuclear science: the Michigan Memorial–Phoenix Project. In addition to producing notable research accomplishments, the project sparked systematic changes in the way the university supported research and it reshaped the university’s relationships with the alumni community and industry.

Nuclear, High Energy, and Solid State Physics
The Blackwell Companion to the History of American Science, ed. Georgina M. Montgomery and Mark A. Largent, 186–98. (Malden, MA: Blackwell, 2016)

When Henry Rowland and 35 of his colleagues established the American Physical Society (APS) in 1899, the fields of nuclear, high energy, and solid state physics did not exist. Ernest Rutherford would not postulate the atomic nucleus until 1911, the cyclotron of Ernest Lawrence and M. Stanley Livingston would not accelerate its first particles until 1931, and no one would earnestly propose grouping physicists according to the phase of matter they studied until 1943. At the Society’s centenary in 1999 its membership topped 41,000 and these fields represented its largest and most powerful constituencies.

Fundamental Disputations: The Philosophical Debates that Governed American Physics, 1939–1993
Historical Studies in the Natural Sciences 45, no. 5 (2015): 703–57. (pdf preprint)

A philosophical debate between particle physicists and solid state physicists roiled as these subdisciplines competed for financial support, social approbation, and intellectual prestige through the second half of the twentieth century. Their disagreement hinged on the nature of fundamental research. The particle physics community adopted a reductionist approach, arguing that the fundamental physical laws were those governing the smallest constituents of matter and energy. Partly in response to this position, solid state physicists developed a range of more permissive perspectives on what type of physics could be fundamental, all of which stressed the importance of higher-level characteristics, maintaining that investigations at many levels of complexity might yield fundamental insight. This paper traces the dispute over fundamentality, which grew both from the specific problems physicists encountered while building their professional infrastructure, and from the demands of funding their research in Cold War America. Through an exploration of how physicists developed philosophical positions within institutional contexts and deployed those positions in their rhetoric, I argue first that professional pressures both motivated and exerted influence over the construction of such views, second that philosophical views had a reciprocal guiding effect on the institutional and professional development of Cold War physics, and third that these views were further bent, blunted, and reshaped when deployed in high-stakes rhetorical discourse. The case studies through which this story unfolds indicate that further attention to such philosophical commitments is warranted when examining the historical development of scientific institutions, communities, and hierarchies.

What’s in a Name Change? Solid State Physics, Condensed Matter Physics, and Materials Science
Physics in Perspective 17, no. 1 (2015): 3–32. (pdf preprint)

When solid state physics emerged in the 1940s, its name was controversial. By the 1970s, some physicists came to prefer ‘‘condensed matter’’ as a way to identify the discipline of physics examining complex matter. Physicists and historians often gloss this transition as a simple rebranding of a problematically named field, but attention to the motives behind these names reveals telling nuances. ‘‘Solid state physics’’ and ‘‘condensed matter physics’’— along with ‘‘materials science,’’ which also emerged during the Cold War—were named in accordance with ideological commitments about the identity of physics. Historians, therefore, can profitably understand solid state and condensed matter physics as distinct disciplines. Condensed matter, rather than being continuous with solid state physics, should be considered alongside materials science as an outlet for specific frustrations with the way solid state was organized.

Evaluating Hidden Costs of Technological Change: Scaffolding, Agency, and Entrenchment
Techné: Research in Philosophy and Technology 19, no. 1 (2015): 1–25. (pdf preprint)

This paper explores the process by which new technologies supplant or constrain cultural scaffolding processes and the consequences thereof. As elaborated by William Wimsatt and James Griesemer, cultural scaffolds support the acquisition of new capabilities by individuals or organizations. When technologies displace scaffolds, those who previously acquired capabilities from them come to rely upon the new technologies to complete tasks they could once accomplish on their own. Therefore, the would-be beneficiaries of those scaffolds are deprived of the agency to exercise the capabilities the scaffolds supported. Evaluating how technologies displace cultural scaffolds can ground philosophical assessments of the cultural value of technologies.

Is the Contingentist/Inevitabilist Debate a Matter of Degrees?
Philosophy of Science 80, no. 5 (2013): 919–30. (pdf preprint)

The contingentist/inevitabilist debate contests whether the results of successful science are contingent or inevitable. This article addresses lingering ambiguity in the way contingency is defined in this debate. I argue that contingency in science can be understood as a collection of distinct concepts, distinguished by how they hold science contingent, by what elements of science they hold contingent, and by what those elements are contingent upon. I present a preliminary taxonomy designed to characterize the full-range positions available and illustrate that these constitute a diverse array rather than a spectrum.
