Replicating Mathematical Inventions: Galileo’s Compass, Its Instructions, Its Students


Abstract Questions about how closure is achieved in disputes involving new observational or experimental claims have highlighted the role of bodily knowledge possibly irreducible to written experimental protocols and instructions how to build and operate instruments. This essay asks similar questions about a scenario that is both related and significantly different: the replication of an invention, not of an observation or the instrument through which it produced. Furthermore, the machine considered here—Galileo’s compass or sector—was not a typical industrial invention (like a spinning jenny), but a mathematical invention (a calculator), that is, a machine that produces numbers, not yarn. This case study describes some of the similarities and differences between replicating experiments, traditional machines producing material outputs, and mathematical inventions yielding calculations or information. This comparison indicates that, as in other kinds of replication, the replication of mathematical inventions involves texts (the calculator’s instructions) but that in this case bodily knowledge cannot be properly described as either tacit or explicit. It rather takes the shape of memory—muscle memory—that may be recalled from reading the instructions.

Ghosts, brands, and influencers: Emergent trends in scientific authorship.


This essay is about the unique role of proper nouns at the intersection of knowledge and property, both tangible and intangible. Nouns are central to any form of property and credit, from a person's name listed on a property deed or copyright registration, to the name of an artist to whom a work is attributed, or that of a scientist after whom a discovery or theory is named. And names can also be found on the other end of the property spectrum, not as the names of authors and owners but as objects of property, as in the case of brand names. Here I trace some of the functions of these names as they move across different scenarios of knowledge-making and property-making, focusing on some of the effects those trajectories are having in the contemporary technosciences as they bring together the function of the author and that of the brand.

Witnessing Astronomy


An analysis of the role of witnessing (and of its legal articulations) in early telescopic astronomy. Mostly focused on the conversations between Kepler and Galileo.
