Matter for Thought - Timeless insights for Modern Physics

👨‍🔬Quote by Pierre Hippolyte Boutigny, French physicist

📚Source: "Studies on Bodies in the Spheroidal State – A New Branch of Physics” (1857)

#physics #experiment #fluiddynamics #theory #STEM
Now, when we encounter an effect whose cause is unknown, the path is clear, and we have followed it. We did for this property what we had done for all the others; we studied it carefully, at least as far as our limited experimental resources would allow, and we looked for its laws in order to coordinate them and establish a theory. What, in fact, is a theory? It is the analytical connection of particular facts with a general fact.

❓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.

Stéphanie Derwael reminds us: scientific image #database are never neutral.
They seem complete, uniform, but are curated fragments — selected, organised, normalised.
Every DB reflects choices — critical thinking is key to #OpenScience.
