The Individual and the Community in Stoic Pragmatism

The present paper outlines John Lachs’s idea of stoic pragmatism and develops its important part that is the relation between the individual and the community. In his project, Lachs reduces the whole tradition of Stoic philosophy to its later, Roman version and tries to link it with the philosophical tradition of American pragmatism (especially William James, John Dewey, and George Santayana, who is close to pragmatism at some points) hoping that it is possible for these two to "enrich and complete each other" so that to provide "a better attitude to life than either of the two views alone." Stoic pragmatism pursues factual improvement in the quality of life for individuals living in given social circumstances, rather than a new theory about such improvement. Interestingly, stoic pragmatism overlaps at many points with the so-called modern stoicism, a movement that uses Stoic ethics in contemporary contexts.&nbsp

Effect of hard processes on momentum correlations in pppp and ppˉp\bar{p} collisions

The HBT radii extracted in p-pbar and pp collisions at SPS and Tevatron show a clear correlation with the charged particle rapidity density. We propose to explain the correlation using a simple model where the distance from the initial hard parton-parton scattering to the hadronization point depends on the energy of the partons emitted. Since the particle multiplicity is correlated with the mean energy of the partons produced we can explain the experimental observations without invoking scenarios that assume a thermal fireball. The model has been applied with success to the existing experimental data both in the magnitude and the intensity of the correlation. As well, the model has been extended to pp collisions at the LHC energy of 14 TeV. The possibilities of a better insight into the string spatial development using 3D HBT analysis is discussed.Comment: 12 pages, 6 figure

Study of Spin-Orbit Interactions and Interlayer Ferromagnetic Coupling in Co/Pt/Co Trilayers in Wide Range of Heavy Metal Thickness

The spin-orbit torque, a torque induced by a charge current flowing through the heavy-metal conducting layer with strong spin-orbit interactions, provides an efficient way to control the magnetization direction in heavy-metal/ferromagnet nanostructures, required for applications in the emergent magnetic technologies like random access memories, high-frequency nano oscillators, or bio-inspired neuromorphic computations. We study the interface properties, magnetization dynamics, magnetostatic features and spin-orbit interactions within the multilayer system Ti(2)/Co(1)/Pt(0-4)/Co(1)/MgO(2)/Ti(2) (thicknesses in nanometers) patterned by optical lithography on micrometer-sized bars. In the investigated devices, Pt is used as a source of the spin current and as a non-magnetic spacer with variable thickness, which enables the magnitude of the interlayer ferromagnetic exchange coupling to be effectively tuned. We also find the Pt thickness-dependent changes in magnetic anisotropies, magnetoresistance, effective Hall angle and, eventually, spin-orbit torque fields at interfaces. The experimental findings are supported by the relevant interface structure-related simulations, micromagnetic, macrospin, as well as the spin drift-diffusion models. Finally, the contribution of the spin-orbital Edelstein-Rashba interfacial fields is also briefly discussed in the analysis.Comment: 39 pages, 14 figure

Philosophy in Digital Culture: Images and the Aestheticization of the Public Intellectual’s Narratives

The present paper deals with the problem of the digital-culture-public-philosophy as a possible response of those philosophers who see the need to face the challenges of the Internet and the visual culture that constitutes an important part of the Internet cultural space. It claims that this type of philosophy would have to, among many other things, modify and broaden philosophers’ traditional mode of communication. It would have to expand its textual, or mainly text-related, communication mode into the aesthetic and visual communication mode. More precisely, philosophers would have to learn how to aestheticize and visualize their ethical (epistemic, ontological, social) narratives by using some digital tools – YouTube clips for example
