The simplicity of physical laws

open access: yesNoûs, Volume 59, Issue 4, Page 957-987, December 2025.
Abstract Physical laws are strikingly simple, yet there is no a priori reason for them to be so. I propose that nomic realists—Humeans and non‐Humeans—should recognize simplicity as a fundamental epistemic guide for discovering and evaluating candidate physical laws.

Energetic Ion Losses Observed During Juno's Close Encounter With Europa

open access: yesGeophysical Research Letters, Volume 52, Issue 21, 16 November 2025.
Abstract We present energetic ion observations made by Juno during its close Europa flyby on 29 September 2022. These data show significant reductions in the ion intensities occurring in the moon's geometric wake region. The most significant losses occur for locally mirroring ions with gyrophases on the anti‐Jovian facing side of the wake.

Water‐Mediated 1,7‐Palladium Aryl‐to‐Aryl Migration in an Unusual Aryne Trimerization Enables the Synthesis of Multihelicenes with Profoundly Hindered Stereogenic Axes

open access: yesAdvanced Synthesis &Catalysis, Volume 367, Issue 21, November 13, 2025.
In the presence of a Pd0 catalyst, large π‐extended arynes trimerize in an unusual manner to forge extremely compact and strained chiral benzenoids. This new trimerization reaction involves a 1,7‐Pd isomerization, a rare and poorly understood process that is elucidated.

On the Origin of Solvent‐Dependent Ultraviolet–Visible Spectral Behavior of the Complexes [R3PAuCl]n (R = H, Me and Et, n = 1,2)

open access: yesEuropean Journal of Inorganic Chemistry, Volume 28, Issue 32, November 10, 2025.
For the linear gold complexes R3PauCl, R = H, Me, Et, immersed in solvent, a dimer aggregation model is required to achieve good agreement between the calculated and experimental absorption spectra using a spin‐orbit/relativistic/solvent model approximation. The solvatochromic effect increases with the dielectric constant up to a saturation point.
