Doing Theory:Life, Ethics, And Force Stefan Helmreich (bio), Daniela Gandorfer and Zulaikha Ayub (bio) Introduction: Theory "Theory is about whose lives matter how." —Stefan Ayub: In this Matterphorical issue, we want to think the production of meaning in its inextricability from matter, with understood not as representational (i.e. a semiotic or symbolic quality quantity), but rather something...

In this paper, a theory of force-free magnetic field useful for explaining the formation convex closed sets, bounded by separatrix in plasma, is developed. This question not new and has been addressed many authors. Force-free fields appear laboratory astrophysical plasmas. These are defined solution problem ∇×B=ΛB with some conditions B∂Ω on boundary ∂Ω plasma region. physical situations, it no...
