REPLAY - "Faut-il en finir avec le h-index ?"

Il y a 20 ans, le physicien Jorge Hirsch proposait un indicateur pour mesurer l'impact des publications scientifiques d'un chercheur. Un indicateur aussi plébiscité que controversé.

❓LeidenForce quiz of the day: can you solve our Fake or Fact?

In our Fake or Fact series, we test your science knowledge about the Leidenfrost effect!

#FluidDynamics #DailyScience #LeidenfrostEffect #Physics #FakeOrFact #HeatTransfer
Fake or fact? The Leidenfrost effect prevents the droplet from touching the surface, so it doesn’t heat up. Answer: FALSE (partly). The vapor layer separating the droplet from the surface strongly limits direct heat transfer. This slows the heating down, but does not suppress it: heat is still transferred through the vapor layer and by internal fluid motion. As a result, the droplet eventually evaporates — much more slowly than with direct contact.

The Leidenfrost effect: when drops levitate
Water droplets can levitate on hot surfaces thanks to a vapor layer. Learn how in this @espciparispsl.bsky.social MOOC video.
