Sur la présence implicite de la notion d’opinion droite dans les dialogues de jeunesse de Platon
Études Platoniciennes, 2016 Nous proposons, dans cet article, une nouvelle interprétation de la déclaration d’ignorance de Socrate. En nous appuyant sur la doctrine platonicienne selon laquelle il n’existe qu’une seule science et sur la représentation du philosophe comme un être ...

Advanced Materials, EarlyView.Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

Flexoelectrically Induced Polar Topology in Twisted SrTiO3 Membranes
Advanced Materials, EarlyView.Twisted SrTiO3 bilayers host polar vortices of flexoelectric origin, revealed through combined experiment and theory. By reconstructing polarization from the toroidal moment of strain gradients, the work establishes a 3D chiral state with broken inversion and mirror symmetries.

Advanced Materials, EarlyView.Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...

The Journal of Experimental Medicine, 2006 In 1947, Paul Beeson showed that rabbits repeatedly injected with certain bacteria eventually become resistant to the bacteria's fever-provoking effects—a phenomenon known as endotoxin tolerance.

Measuring the Hall Effect in Hysteretic Materials
Advanced Materials, EarlyView.The authors highlight common pitfalls in measuring the Hall effect: in hysteretic magnets, improper data processing can create signals that look exotic but are not real. This Perspective explains the origin of these artifacts and presents practical measurement strategies that help researchers identify reliable Hall responses in complex magnetic ...

Advanced Materials, EarlyView.Field‐programmed anisotropy imparts material‐level intelligence to soft composites. Magnetic torque dynamics drive magneto‐piezoelectric nanowires from random dispersion into deterministic axial alignment. The resulting hierarchical percolation networks confine electromechanical coupling to specific axes and intrinsically decouple superposed force ...

The Arrogance of Ignorance—Ignoring the Ubiquitous [PDF]
American Zoologist, 1984 Anti-evolution, the rise of pseudo sciences, and the renewed interest in the occult, all masquerading as science, are symptomatic of the poor job that is done explicating science as a process and a way of knowing. Disciplinary teaching emphasizes fact over concept. Every science discipline should be taught witha process base pervasive from the first to

Giant Anisotropy and High Second‐Order Nonlinearity of 3R‐MoS2 for Multifunctional Photonics
Advanced Materials, EarlyView.Graphical abstract highlights, 3R‐polytype of MoS2 (3R‐MoS2) as a multifunctional photonic platform enabled by giant optical anisotropy and optical nonlinearities, demonstrating subdiffractional waveguiding, giant second‐harmonic (SH) generation, and high‐performance reflective polarization control.
