Archimedes’ law explains penetration of solids into granular media [PDF]
Nature Communications, 2018 The penetration dynamics of solid objects into granular media has been described by theories that are constrained to the use of phenomenological models or empirical parameters. Here, Kang et al.

Direction of Spontaneous Processes in Non-Equilibrium Systems with Movable/Permeable Internal Walls [PDF]
EntropyWe consider three different systems in a heat flow: an ideal gas, a van der Waals gas, and a binary mixture of ideal gases. We divide each system internally into two subsystems by a movable wall.

Negligible contribution of body density to in-water vertical jump performance in elite male water polo players. [PDF]
PLoS ONEThe aim of this study was to investigate the associations among in-water vertical jump and various dry-land physical measures by taking the law of Archimedes into consideration, and by normalizing the dry-land measures both to body density and body mass.

Analysis of monomer ratios in a dimethacrylate mixture using positron annihilation spectroscopy [PDF]
Scientific ReportsDimethacrylate based samples suitable for photopolymerization are usually used in mixtures with different ratios. In the case of the monomers D3MA and UDMA, the ideal monomer ratio of 1:1 was reported in the literature and designed as 2 M. Dimethacrylate-

The geometry of isochrone orbits: from Archimedes’ parabolae to Kepler’s third law [PDF]
Celestial Mechanics and Dynamical Astronomy, 2020 In classical mechanics, the Kepler potential and the Harmonic potential share the following remarkable property: in either of these potentials, a bound test particle orbits with a radial period that is independent of its angular momentum. For this reason, the Kepler and Harmonic potentials are called \it{isochrone}.
