The article "Knots, Quandles, and Homology" presents an introduction to the combinatorial theory of knots. It discusses the fundamental groups of knots, coloring invariants, and invariants given by quandles and quandle homology. Knot theory uses techniques from geometry, algebra, and analysis to understand knots in real life. Knots can be classified using invariants and have applications in biology, physics, and cryptography. The article also mentions Reidemeister's theorem, which states that two knots are equivalent if their diagrams are connected by Reidemeister moves. Examples of famous knots, such as the trefoil knot and the figure-eight knot, are presented, and knot coloring using quandles is discussed. Additionally, the concept of the fundamental quandle of a knot is introduced as an invariant that generalizes the fundamental group and coloring invariants. The article also discusses the theory of abelian extensions of quandles and their application in knot theory. [Extracted from the article]

This article introduces a critical comment on Oliver Marchart's book Thinking Antagonism. Political Ontology after Laclau. The authors identify how Marchart, while assuming the same political aim as his mentor Ernesto Laclau -- i.e. 'to make politics thinkable again' --, does so from an 'eccentric' place in regard to the philosophical field. Indeed, Marchart's main objective is to put antagonism back into its place. Why should antagonism be put back into its place? Because Laclau would have displaced it from the previous ontological status that he himself -- along with Chantal Mouffe -- had given to it when he later introduced the notion of dislocation. The authors propose a psychoanalytical reading of Laclau's work arguing that psychoanalysis also allows to decipher the fundamental place that antagonism has in the theory of hegemony. From this perspective they set out to think antagonism from the theory of knots, thereby specifying the notion of contingency and the subject's place and considering how affection is at the basis of Laclau's theory.
