Towards a representation of diffusion and interaction of scientific ideas: The case of fiber optics communication

The research question studied in this contribution is how to find an adequate representation to describe the diffusion of scientific ideas over time. We claim that citation data, at least of articles that act as concept symbols, can be considered to contain this information. As a case study we show how the founding article by Nobel Prize winner Kao illustrates the evolution of the field of fiber optics communication. We use a continuous description of discrete citation data in order to accentuate turning points and breakthroughs in the history of this field. Applying the principles explained in this contribution informetrics may reveal the trajectories along which science is developing.

► A representation for the diffusion of scientific ideas over time is proposed.
► This representation makes use of citations.
► Nobelist Kao’s main article is a concept symbol for fiber optic communication.
► It shows the developments of its field.
► The notions of instantaneous velocity and acceleration are introduced.
