J'ai fait une petite simulations rigolote pour vérifier numériquement un vieux truc que j'ai trouvé dans un article de Boltzmann. Si on met une particule dans un plan avec deux ressorts qui ont des constantes de forces k1 et k2, la trajectoire est périodique si k1/k2 est un nombre rationnel: youtu.be/keGGbb2uiB8

Évidemment si c'est pas un nombre rationnel (genre pi), c'est pas périodique: youtu.be/Tty0jFWKkv8

Voilà, c'est tout pour moi.

Good grief. Boltzmann's brain in the comics.
questionablecontent.net/view.p I liked this answer "If you ask me, it doesn't matter if we're just a bunch of bits and bytes as long as we're experiencing our lives!" similar was said in the movie "Free Guy"
I liked Susskind's answer to the question of whether we lived in a computer....

In 1879, Stefan and Boltzmann showed the law for how heat radiates from a black body. #Poetry #Science #History #Thermodynamics #Stefan #Boltzmann (sharpgiving.com/thebookofscien)

Drawing of the formula j* = delta T to the fourth power. Black-body radiant exitance is directly proportional to the fourth power of the body's thermodynamic temperature.

"The authors introduce the two main theoretical approaches in SM, Boltzmannian SM and Gibbsian SM, and discuss how they conceptualise equilibrium and explain the approach to it. In doing so, the authors examine how probabilities are introduced into the theories, how they deal with irreversibility, how they understand the relation between the micro and the macro level, and how the two approaches relate to each other."

Licht mit negativer absoluter Temperatur (scinexx)
Es klingt paradox, ist aber physikalisch solide: Physiker haben #Licht so manipuliert, dass es sich wie ein Gas bei negativer absoluter Temperatur verhält. Diese herrscht nach der #Boltzmann-Verteilung dann, wenn die Mehrheit der Teilchen maximale Energiezustände einnimmt.
