Peter Grassberger

Peter Grassberger (born May 17, 1940) is a professor well known for his work in statistical and particle physics. He is most famous for his contributions to chaos theory, where he introduced the idea of correlation dimension, a means of measuring a type of fractal dimension of the strange attractor.

Work

Grassberger's early work focused on particle phenomenology, in particular on the formulation of formally exact equations for three-body scattering and bound state scattering (Alt-Grassberger-Sandhas equation).

While working at CERN, he realized that reggeon field theory can be viewed as a contact process in the same universality class as directed percolation. After making this discovery, Grassberger turned his attention to the studies of statistical physics, dynamical systems, sequential sampling algorithms, and complex systems. His publications span a variety of topics including reaction-diffusion systems, cellular automata, fractals, Ising model, Griffiths phases, self-organized criticality, and percolation.

He held long-term positions at the University of Wuppertal and at the Forschungszentrum Jülich (Germany). Other positions that lasted between 2 years and 3 months were at CERN, at the Universities of Kabul, Nice, Calgary, Rome and Utrecht, the Weizmann Institute, the Max Planck Institute for the Physics of Complex Systems in Dresden, the Istituto nazionale di ottica in Florence, and at the Institute for Advanced Studies in Basic Sciences in Zanjan, Iran.

In 2017 he received the EPS Statistical and Nonlinear Physics Prize.

gollark: Which is pointless code when you can just write a data structure and some functions for handling it.
gollark: Okay. This doesn't make you right.
gollark: I do care about writing lots of extra code for no good reason myself.
gollark: Okay. Well, I don't. Encapsulating data in classes means you write a lot of boilerplate and have a lot of fiddly state.
gollark: This is pointlessly meta, can we actually discuss OOP vs FP usefully?
