Taking census of physics

Federico Battiston from the Center for Network Science - Central European University (Budapest) will be presenting at a SODAS Talk Tuesday the 4th of December 2018.


There was a time when polymaths like Galileo knew all the physics that was there to be known. Over the centuries, however, the body of knowledge spanned by physics exploded, encompassing topics as diverse as gravitational waves, graphene, or network science. As physics expanded in breadth and depth, physicists were forced to specialise, segmenting researchers into their narrow, specialised communities. How many physicists work in each subfield of physics today and how does each subdiscipline evolve? In which subfield are physicists “born” into and where do they migrate, if at all? Which physics communities are the most productive, and have the highest impact? Here we take an intellectual census of physicists, their activities and career trajectories, helping us gaining quantitative insights about several fundamental scientific processes, from resource allocation to the exchange of knowledge, and understand the evolution of one of the oldest scientific fields.

The SODAS Talk will take place in building 35, 2nd floor, room 36 (35.2.36) of the CSS Campus, Copenhagen University, from 11.00am - 11.45am.
