The Spaces of Knowledge: Bertrand Russell, Logical Construction, and the Classification of the Sciences.Omar W. Nasim -2012 -British Journal for the History of Philosophy 20 (6):1163-1182.detailsWhat Russell regarded to be the ‘chief outcome’ of his 1914 Lowell Lectures at Harvard can only be fully appreciated, I argue, if one embeds the outcome back into the ‘classificatory problem’ that many at the time were heavily engaged in. The problem focused on the place and relationships between the newly formed or recently professionalized disciplines such as psychology, Erkenntnistheorie, physics, logic and philosophy. The prime metaphor used in discussions about the classificatory problem by British philosophers was a spatial (...) one, with such motifs as ‘standpoints’, ‘place’ and ‘perspectives’ in the space of knowledge. In fact, Russell’s construction of a perspectival space of six-dimensions was meant precisely to be a timely solution to the widely discussed classificatory problem. (shrink)
Observation, working images and procedure: the ‘Great Spiral’ in Lord Rosse's astronomical record books and beyond.Omar W. Nasim -2010 -British Journal for the History of Science 43 (3):353-389.detailsThis paper examines the interrelations between astronomical images of nebulae and their observation. In particular, using the case of the ‘Great Spiral’ , we follow this nebula beginning with its discovery and first sketch made by the third Earl of Rosse in 1845, to giving an account, using archival sources, of exactly how other images of the same object were produced over the years and stabilized within the record books of the Rosse project. It will be found that a particular (...) ‘procedure’ was employed using ‘working images’ that interacted with descriptions, other images and the telescopic object itself. This stabilized not only some set of standard images of the object, but also a very potent conception of spirality as well, i.e. as a ‘normal form’. Finally, two cases will be contrasted, one being George Bond's application of this spiral conception to the nebula in Orion, and the other Wilhelm Tempel's rejection of the spiral form in M51.

Extending the Gaze: The Temporality of Astronomical Paperwork.Omar W. Nasim -2013 -Science in Context 26 (2):247-277.detailsArgumentKeeping records has always been an essential part of science. Aside from natural history and the laboratory sciences, no other observational science reflects this activity of record-keeping better than astronomy. Central to this activity, historically speaking, are tools so mundane and common that they are easily overlooked; namely, the notebook and the pencil. One obvious function of these tools is clearly a mnemonic one. However, there are other relevant functions of paperwork that often go unnoticed. Among these, I argue, is (...) the strategic use made of different procedures of record keeping to prolong observational time with a target object. Highlighting this function will help us to appreciate the supporting role played by the notebook and the pencil to extend the observational time spent with a target object. With objects as delicate, faint, and mysterious as the nebulae, the procedures used to record their observations helped nineteenth-century observers overcome the temporal handicaps and limitations of large and clumsy telescopes, mounted in the altazimuth manner. To demonstrate the importance of paper and pencil, I will closely examine the observing books, the drawings found therein, and the telescopes of three nineteenth-century observers of the nebulae: Sir John F. W. Herschel, Lord Rosse, and William Lassell. (shrink)

Observing by Hand: Sketching the Nebulae in the Nineteenth Century.Omar W. Nasim -2013 - University of Chicago Press.detailsToday we are all familiar with the iconic pictures of the nebulae produced by the Hubble Space Telescope’s digital cameras. But there was a time, before the successful application of photography to the heavens, in which scientists had to rely on handmade drawings of these mysterious phenomena. Observing by Hand sheds entirely new light on the ways in which the production and reception of handdrawn images of the nebulae in the nineteenth century contributed to astronomical observation. Omar W. Nasim investigates (...) hundreds of unpublished observing books and paper records from six nineteenth-century observers of the nebulae: Sir John Herschel; William Parsons, the third Earl of Rosse; William Lassell; Ebenezer Porter Mason; Ernst Wilhelm Leberecht Tempel; and George Phillips Bond. Nasim focuses on the ways in which these observers created and employed their drawings in data-driven procedures, from their choices of artistic materials and techniques to their practices and scientific observation. He examines the ways in which the act of drawing complemented the acts of seeing and knowing, as well as the ways that making pictures was connected to the production of scientific knowledge. An impeccably researched, carefully crafted, and beautifully illustrated piece of historical work, Observing by Hand will delight historians of science, art, and the book, as well as astronomers and philosophers.

The Emergence of Analytic Philosophy and a Controversy at the Aristotelian Society: 1900-1916.Omar W. Nasim -unknowndetailsFor this year’s Virtual Issue, our guest editor, Omar W. Nasim, has collected together papers from the Aristotelian Society archives that represent a substantial part of a dispute that contributed to the emergence of analytic philosophy in Britain at the turn of the 20th Century. The dispute was primarily concerned with the problem of the external world – the nature of the sensible objects of perception, and how they relate to physical things and the perceiving subject. The participants in this (...) controversy contested the nature of the appearance-reality distinction, whether it is it is possible for a thing to instantiate contrary sensible qualities at the same place and time, the distinction between presentation and representation, the nature of knowledge by acquaintance, and the nature of sense-data – e.g., whether sense-data are psychical or physical, whether they persist unperceived, and how they give rise to knowledge of the external world. G. E. Moore and Bertrand Russell were significant contributors to these debates, but so too were several philosophers whose names are now less well known: G. F. Stout, G. Dawes Hicks, Abraham Wolf, T. Percy Nunn, and S. Alexander. This Virtual Issue collects together, for the first time, the important contributions made to these debates by all of these figures. In doing so it provides a fascinating insight into the ways in which Russell’s earliest attempts to construct the external world from sense-data were influenced by the ideas and arguments of his immediate contemporaries. Omar W. Nasim’s specially commissioned introduction to the Virtual Issue sets out the historical context of these disputes about the external world, and details the prominent role played by the Aristotelian Society in making them possible.

The ‘Landmark’ and ‘Groundwork’ of stars: John Herschel, photography and the drawing of nebulae.Omar W. Nasim -2011 -Studies in History and Philosophy of Science Part A 42 (1):67-84.detailsThis paper argues for continuity in purpose and specific results between some hand drawn nebulae, especially those ‘descriptive maps’ by John F. W. Herschel and E. P. Mason in the late 1830s, and the first photographs made of the nebulae in the 1880s. Using H. H. Turners’ explication in 1904 of the three great advantages of astrophotography, the paper concludes that to some extent Herschel’s and Mason’s hand-drawings of the nebulae were meant to achieve the same kinds of results. This (...) is surprising not only because such drawings were conceived and achieved over forty-years earlier, but also because the procedures used in the production of these pictorially and metrically rich images were those directly inspired by cartography, geodesy, and land-surveying. Such drawings provided the standard for what was depicted, expected and aimed at by way of successful representations of the nebulae; standards that seemed to have been used to judge the success of nebular photographs. Being conditions of expectation and possibility for later photography, these drawings were themselves made possible by such techniques of representation and measurement as isolines and triangulation, so fundamental to Imperial and ‘Humboltian science.’Keywords: Ebenezer Porter Mason; Cartography; Draughtsmanship; Observation; Scientific Representation; Philosophy of Scientific Practice.
