  2. The #paperOfTheDay is a classic of #thermodynamics : "Equation of state in the Neighborhood of the critical point" from 1965. Here, Benjamin Widom introduces what is now known as "Widom scaling".
    Generically, the properties of a fluid might depend on parameters, such as temperature or density, through power laws. There are certain critical points in the phase space, i.e. certain temperatures, densities, etc., where the behaviour of the fluid changes qualitatively. The observation is that close to the critical point, the exponents of the various power laws have different numerical values than what one would expect classically. For example, the specific heat diverges at a power law, but the exponent of divergence is not what one would expect from the conventional equation of state.
    Widom's paper now makes a specific conjecture: Near a critical point, the equation of state should be altered by introducing an arbitrary function of density of temperature, however, this function is assumed to be homogeneous. That is if x is temperature and y is density, it is a function of the form e.g. x^c * f(y/x), where f is an arbitrary function of y/x, and c is a constant. It turns out that almost all experimental observations can be described from this conjecture without knowing the functional form of f. The scaling exponent c alone is sufficient to give rise to the non-classical power laws and the relations between them.
    This paper is significant because it is an early (and purely heuristic) version of universality: The behaviour of systems in #statisticalPhysics at the critical point is largely determined from structural properties, independently of concrete details.

  9. I have a steam powered tea pot let me explain

    It's one of those translucent plastic cylinders molded with a tight fitting lid that has two spouts: one with a square opening and another with a grate that doesn't filter small things like broken leaf tea.

    Hot tea in this tea pot contains water with a high vapor pressure, one that is high enough to evaporate enough water to create a pressure large enough to lift the lid. The pressure inside and out was atmospheric pressure until water began evaporating from the tea I put in the tea pot.

    The lid doesn't lift very far, but the bearing surface is tea, so the friction is low enough for the lid to move up.

    Or conversely there is a small passage, albeit larger than all the rest, through which I can hear bubbles popping as the evaporated water leaves the tea pot. What was initially a flat interface between the membrane of tea and the external atmosphere was pushed out by this pressure difference. The push was the water vapor and air pushing against the surface tension of the tea membrane. It takes force to deform a fluid membrane.

    So my steam powered tea pot is running on the heat energy in the hot tea inside it. The work it is doing could be lifting the lid but it surely is popping water bubbles that I can hear.

  10. 🤣 Oh, you thought you'd be defying gravity by throwing statistical physics into JavaScript? 🚀 Spoiler alert: no amounts of buzzwords or IDEs will magically transform your code into something comprehensible. Next time, just stick to IMDB stalking for a real challenge! 🙄

  11. 🔥 Dive into the riveting world of statistical physics with #R, where you'll realize that writing endless lines of code for Monte Carlo #simulations is SO much more fun than watching paint dry! 🎨✨ But wait, there's more: GitHub's #AI is here to save the day by doing absolutely nothing to alleviate the tedium! 🤖💤

  14. Anyway. Sorry for the spam, but would anyone like to read a barely technical blog post I wrote about #StatisticalPhysics and optionally give me some feedback before I make it public? :)

  15. re-#introduction
    Hi Fediscience! I am an Assistant Professor of Mechanical Engineering at University of Hawaiʻi at Mānoa (Honolulu). I got here starting from Physics training with many scientific detours into data-driven models, complex systems, nanomaterial self-assembly, human learning of complex networks, naval ships, and design problems.
    I grew up in Belarus and have *opinions* on that region of the world. I've been on Fediverse since late 2022 when *something* happened to our previous cybersocial infrastructure, but the previous server I was on is sunsetting. Please come say hi and recommend cool people to follow here.
    I have a blog with longer thoughts on science-adjacent topics.

  16. Ever since I read through the beginning of David Tong's statistical notes, I've been fascinated by how independent the notion of temperature is from laws of physics. To get a notion of "temperature of a system", basically all you need is 1/ a way to assign a set of possible microstates and macrostates (along with a probability distribution for them) to a system 2/ a notion of energy, that is, a quantity that is extensive (i.e. the energy of the combination of two systems is the sum of their individual energies) and conserved.

    This got me thinking: in our universe, there are many more extensive, conserved quantities (mass, charge, linear/angular momentum along the x/y/z-axis...). What happens if you take the definition of temperature and just swap energy for one of those other quantities? I can't imagine no one has ever considered that!
