A brief history of x-rays

The identity of x-rays was initially mysterious, their connotations including morbidity and the otherworldly. Gradually they became routine, finding a place in the high-energy end of the electromagnetic spectrum. Radiologists established a niche in hospitals, contributing to the industrialization of healthcare. Control of x-ray tube output was improved while an infrastructure enforcing radiation protection accompanied the continued growth of the field. X-ray diffraction proved a powerful tool with which to examine substances at the atomic scale. Since 1950, x-ray researchers have taken advantage of synchrotrons’ copious production of continuous x-ray spectra, and the marriage of x-rays with electronics has led to a cornucopia of cheap and highly efficient analytical tools.     

Ethical gaps in studies of the digital divide

There are many reports about the digital divideand many discrepant interpretations of what thereports indicate. This pattern of competinganalyses, often in relation to identical datasets, has endured for a good part of the lastdecade. It is argued here that a major problemwith much of the digital divide research is afailure to include ethical concerns as anexplicit part of analyzing and interpretingdigital divide gaps. If researchers includemore recognition of ethics with their findingsabout divide gaps, it is likely that they willproduce better research and findings as well asmore defensible linkages between study reportsand policy deliberations.     

A lens of many facets. Science through a family's eyes

This essay argues for the relevance of the history of family life to the history of science, taking the example of the Exners of Vienna. The Exners were an influential case of the nineteenth-century European phenomenon of the "scientific dynasty". The focus here is on their collaborative research on color theory at the turn of the twentieth century. At first glance, this project looks like a reactionary strike against aesthetic innovation, a symptom of what historians assume was an unbridgeable gulf between scientific reason and artistic modernism. We can better understand the Exners' motivations by situating this research at the intersection of the family's public and private lives. The domestic context sheds light on their use of such scientific terms as "subjective", "normal", and "universal", providing a more nuanced sense of what rationality really meant in fin-de-siècle Vienna.     

Making knowledge: history, literature, and the poetics of science

As a field of study, literature and science has gradually expanded to encompass both the impact of science on literary culture and the literary-linguistic practices intrinsic to the production of scientific knowledge. Such transformations both reinforce and fundamentally recalibrate the detailed attention focused on scientific practice by historians of science since the 1980s. As a result, this essay and the Focus section it introduces suggest that history of science and literature and science are, in fact, interdependent fields. Attention to their convergences will yield better understanding of the performative dimensions of scientific practices and thence of science itself as a form of making of knowledge of things and events in the world of nature. Science as a form of making involves the convergence of things, material practices, and a panoply of meaningful artifacts-instruments of thought and action-that refuse any simple dichotomy between "text" and "action."
