Kuhn on reference and essence

Alexander Bird (2004)

Philosophia Scientiae

Similarity:

Kuhn’s incommensurability thesis seems to challenge scientific realism. One response to that challenge is to focus on the continuity of reference. The causal theory of reference in particular seems to offer the possibility of continuity of reference that would provide a basis for the sort of comparability between theories that the realist requires. In “Dubbing and Redubbing: The Vulnerability of Rigid Designation” Kuhn attacks the causal theory and the essentialism to which it is related....

Simulation of electrostatic field in electrospinning of polymer nanofibers

Y. Li, X. Zhang, E. Trudick, G.G. Chase (2015)

Nanoscale Systems: Mathematical Modeling, Theory and Applications

Similarity:

Electrospinning is a popular process for fabricating submicron diameter gibers. The process applies a strong electric gield to launch a polymer jet that elongates to create the gine gibers. The jet dries as the solvent evaporates and the dried giber collects on a grounded surface. Most of electrospinning literatures focus the polymer solution compositions and the properties of the produced gibers. Less attention is applied to the electrostatic gield geometries and operating conditions....
