From absolute nonsense to the world's operating system.

Informatics, its artefacts and methods, have fundamentally changed our society and world, from the individual personal level up to the current geo-political powerplay between the US, China and Europe. Information Technology serves as the operating system of our society. This change has happened over the last 30 - 40 years, and the result should be compared with our historic views and expectations.

On the uncertainty of interdisciplinarity measurements due to incomplete bibliographic data.

The accuracy of interdisciplinarity measurements is directly related to the quality of the underlying bibliographic data.

This is the case for the Rao-Stirling index, which cannot handle references that are not categorized into disciplinary fields.
