Kant's Metaphysics of Race, Its Distinctiveness, and Its Normativity
Journal of Social Philosophy, EarlyView.ABSTRACT Drawing on the contemporary taxonomy of the metaphysics of race, this paper shows that Kant's theory of race occupies a distinct metaphysical position on race. Second, it argues that Kant's metaphysics of race inherently produces racist claims.

Limitations of graphene nanocoated optical tapers for high-power nonlinear applications
Optical Materials: X, 2019 In this letter, we investigate the limitations of graphene as a saturable absorber for high-power nonlinear optical applications. The response of graphene nanocoated optical tapers against the average optical power injected is tested.

Natural Sciences, Volume 6, Issue 3, July 2026.ABSTRACT Thomas Kuhn's The Structure of Scientific Revolutions (1962) was a blockbuster publication that problematized notions about the origins and nature of scientific revolutions. What became Kuhn's famous rubrics of “normal science” and “paradigms” were similar to concepts of “tacit knowledge” and scientific “frameworks” or “dogmas” in Michael ...

Natural Sciences, Volume 6, Issue 3, July 2026.Within quantum chemistry, density functional theory (DFT) is a revolution. This serves as an example of a multitude of other scientific events, supporting the idea that revolutions are always large, if observed with the appropriate magnification. ABSTRACT Distinguishing scientific revolutions from normal science is a subjective, conflicting matter ...
