The Spin–Spin Problem in Celestial Mechanics
AbstractWe study the dynamics of two homogeneous rigid ellipsoids subject to their mutual gravitational influence. We assume that the spin axis of each ellipsoid coincides with its shortest physical axis and is perpendicular to the orbital plane. Due to such assumptions, the problem is planar and depends on particular parameters of the ellipsoids, most

Catholic Civics Education in the Early Cold War: Zeal for Democracy, Zeal for Christ
Abstract In the late 1940s and 1950s American Catholic educators faced the dilemma of how to transmit Catholic faith and culture to the next generation while also reassuring their non‐Catholic neighbors that they were fully American in lifestyle and loyalties.

Knowledge as a collective status
Abstract While social epistemology is a diverse field, much of it still understands knowledge as an individual status—albeit an individual status that crucially depends on various social factors (such as testimony). Further, the literature on group knowledge until now has primarily focused on limited, specialized groups that may be said to know this or

After 1850, Laplacian or Amperean molecular physics found itself in competition with other approaches involving thermodynamics and kinetic theories. Henri Poincaré is one of the very few French scientists to have made a significant contribution to the ...

DYNAMICAL EVOLUTION NEAR-PARABOLIC COMETS TO HALLEY-TYPE ORBITS
The capture of comet from the near parabolic flux of the Oort cloud to Halley-type orbits (P < 200 yr, perihelion distanses q < 1,5 AU, and Tisserand parametr T < 2) is investigated Two types of capture into Halley-type orbits are found.

Editorial for the Special Issue “Relativistic Astrophysics”
Relativistic Astrophysics is the branch of astrophysics that studies astronomical phenomena and celestial bodies, for which classical mechanics and Newton’s law of gravitation are inapplicable to creation of suitable models and we have to generalize ...

Ephemerides and Celestial Mechanics [PDF]
When solving some abstract problems in mechanics related to the dynamics of bodies and systems, the notion of an inertial frame of reference is introduced in an apparently clear and natural way by simply drawing its coordinate axes and then paying no further attention to the system of reference which is then taken for granted.

Getting a grip: On causation, agency, and the meaning of “manipulation”
Abstract In the philosophy of causation, manipulationist literature is broadly divided into agency and interventionist accounts. The division between these accounts is partially due to a dispute regarding the meaning of “manipulation”, which specifically questions, “Must one analyse manipulation by appealing to human agency?” This paper attempts to ...

Symmetries in central-force problems [PDF]
The two-body problem in central fields (reducible to a central-force problem) models a lot of concrete astronomical situations. The corresponding vector fields (in Cartesian and polar coordinates, extended via collision-blow-up and infinity-blow-up ...
