The final results of the MICROSCOPE mission reach record precision The MICROSCOPE mission has just confirmed the principle of equivalence with a record precision of a few 10-15. It thus proves that bodies fall in vacuum with the same acceleration regardless...
SUPERFLUID HELIUM AND NEGATIVE PRESSURES Low temperature liquid helium-4 is a model material for condensed matter physics for two reasons. First, atomic interactions are weak and quantum effects play an important role on the macroscopic scale. Secondly,...
A surprisingly large Casimir force at biophysical interfaces Biophysical interfaces involve electrolytic media such as salt water where Debye screening due to moving ions is extremely effective. It was therefore commonly believed that interactions induced by...
A mosaic made of spins During the past decades, scientists have tried solving problems that take a long time with conventional computers. Recently, it has been demonstrated that quite a few of these problems can be written as a variation of what is called an...
Jean-Michel Courty, one of the recipients of the first CNRS Medal for Scientific Mediation Jean-Michel Courty, physicist in the field Scientific mediation is based on individual or collective will to get involved in spreading scientific culture and promoting...
