A Soft Matter paper by Roberto Piazza and co-workers has been
highlighted on a number of Italian news-sites, ANSA, Sole 24 Ore
and Galileo. The paper combines experimental and theoretical
studies on what buoyancy actually is, and its relation to the
Archimedes’ principle. What buoyancy really is. A generalized
Archimedes’ principle for sedimentation and ultracentrifugation

Published June 28, 2012 13:55 It is the Archimedes’ Principle: a
body immersed in a fluid receives an upward thrust equal to the
weight of the volume of fluid displaced. A definition that all
children learn from from school, established since twenty-three
centuries. Yet, this time they are the researchers at
Politecnico of Milan to proclaim the famous “Eureka!”: their
studies have shown that in
