Complex systems fascinate because of the way dynamic microscopic interactions give rise to striking, often unexpected macroscopic structures: convection cells in fluids, patterns in ecosystems, ...

The dynamics of an interaction are the movements or exchanges between the parties – what both parties do, say, think, and feel. Relationship dynamics are repeated patterns of interactions. The ...

Quantum-physical fundamentals can be studied particularly well by the interactions between electrons and photons. Excited with laser light, for example, the energy, mass or velocity of the electrons ...
