Galileo's ship and the relativity principle

open access: yesNoûs, EarlyView.
Abstract It is widely acknowledged that the Galilean Relativity Principle, according to which the laws of classical systems are the same in all inertial frames in relative motion, has played an important role in the development of modern physics. It is also commonly believed that this principle holds the key to answering why, for example, we do not ...

Heavy‐duty conceptual engineering

open access: yesNoûs, EarlyView.
Abstract Conceptual engineering is the process of assessing and improving our conceptual repertoire. Some authors have claimed that introducing or revising concepts through conceptual engineering can go as far as expanding the realm of thinkable thoughts and thus enable us to form beliefs, hypotheses, wishes, or desires that we are currently unable to ...

Assessing Input Legitimacy of Occupational Pensions in Europe

open access: yesRegulation &Governance, EarlyView.
ABSTRACT As private asset‐based welfare like funded occupational pension schemes gain importance, legitimacy concerns arise due to financial market downturns and low investment returns. This paper assesses their input legitimacy by distinguishing between individual‐direct and collective‐representative input possibilities in decision‐making processes ...

“M. Leibnits étoit un grand homme”: The role of argument from epistemic authority in Du Châtelet's dispute with Mairan

open access: yesThe Southern Journal of Philosophy, EarlyView.
Abstract In my article, I propose to analyze the Du Châtelet‐Mairan dispute from the perspective of the modern theory of argumentation, focusing on the study of arguments from authority. I study separately the opinions of Du Châtelet and Mairan on the correct use of the argument from authority (Is the opponent using the argument correctly?

Chaotic Dynamics of the Kepler Problem with Oscillating Singularity

open access: yes, 2016
We prove the presence of chaotic dynamics for the classical two-body Kepler problem with a time-periodic gravitational coefficient oscillating between two fixed values.

An alternative algebraic method for solving the radial equation for the hidrogen atom

open access: yesMomento, 1993
A pair of ladder operators are introduced and are for solving the radial equation for the hydrogen atom. The energy eigenvalues as well explicit analytic expressions for the eigenfunctions of this particular Kepler problem are obtained after some ...

Does the Shadow Economy Cast a Cloud on Banking Sector Resilience?

open access: yesScottish Journal of Political Economy, EarlyView.
ABSTRACT Employing 127 countries over the 1991–2017 period, we investigate whether the shadow economy affects banking sector resilience, as measured by bank non‐performing loans, bank capital to total assets, and bank regulatory capital to risk‐weighted assets.

Function Art: Linking Mathematics, Technology, and Visual Arts

open access: yesSchool Science and Mathematics, EarlyView.
ABSTRACT This study investigated students' understanding of mathematical functions and strategies to create artwork using GeoGebra. It was framed by the principles of constructionism and examined how students use functions in creating artworks. We gathered data from students' artworks using the Algebra view and the Construction Protocol in the GeoGebra

Formation history of open clusters constrained by detailed asteroseismology of red giant stars observed by Kepler

open access: yesEPJ Web of Conferences, 2017
Stars originate by the gravitational collapse of a turbulent molecular cloud of a diffuse medium, and are often observed to form clusters. Stellar clusters therefore play an important role in our understanding of star formation and of the dynamical ...
