Though a cornerstone of thermodynamics, entropy remains one of the most vexing concepts to teach budding physicists in the classroom. Physics teachers designed a hand-held model to demonstrate the ...

We study the convergence to equilibrium of a class of nonlinear recombination models. In analogy with Boltzmann's H-theorem from kinetic theory, and in contrast with previous analysis of these models, ...

Bayesian model averaging (BMA) is a popular ensemble-based postprocessing approach where the weighted average of the individual members is used to generate predictive forecasts. As the BMA formulation ...

Physicists have upended a foundational law of materials science by heating gold to over 19,000°C — more than 14 times its melting point — while it remained perfectly solid. The study, published in ...

Black holes are intriguing astronomical objects that have a gravitational pull so strong that it prevents any object and even light from escaping. While black holes have been the topic of numerous ...

WASHINGTON, Sept. 6, 2023 – Though a cornerstone of thermodynamics, entropy remains one of the most vexing concepts to teach budding physicists in the classroom. As a result, many people oversimplify ...
