Scientists simulate a black hole in a water tank

Certain phenomena that occur in black holes but cannot be directly observed in astronomic investigations can be studied by means of a laboratory simulation. This is possible due to a peculiar analogy between processes that ...

A model for describing the hydrodynamics of crowds

Precise simulations of the movement and behavior of crowds can be vital to the production of digital sequences or the creation of large structures for crowd management. However, the ability to quantitatively predict the collective ...

Hydrodynamics in cell studies

In collaboration with ETH Zurich, our team at IBM Research – Zurich published an article reviewing the interaction of liquid flows with biological cells. Our work was featured on the cover of the May 23 issue of Chemical ...

Role of thrust and drag clarified for swimming microorganisms

For years, B. Ubbo Felderhof, a professor at the Institute for Theoretical Physics at Germany's RWTH Aachen University, has explored the mechanisms that fish and microorganisms rely on to propel themselves. Flying birds and ...
