Knot spinning
This exposition is intended to provide some introduction to higher-dimensional knots embeddings of Sn−2 in S through spinning constructions. Once our shoe laces, those archetypical hand tools of knot theory, have been turned into spheres, how can we construct and visualize concrete examples of such knots? There are many important ways to construct higher-dimensional knots. If we are interested ...
متن کاملEnergy Spectra of spinning particles around spinning strings in
Riemannian Killing conserved currents are used to find the energy spectra of classical spinning particles moving around a spinning string in Einstein-Cartan (EC) theory of gravity. It is shown that a continuos spectrum is obtained for planar open orbits while a discrete spectrum is obtained for circular planar orbits. A spin-spin effect between the spin of the test particle and the spin of the ...
متن کاملModified Linear Theory for Spinning or Non-Spinning Projectiles
Static and dynamic stability are the most important phenomena for stable flight atmospheric motion of spin and fin stabilized projectiles. If the aerodynamic forces and moments and the initial conditions are accurately known, an essentially exact simulation of the projectile’s synthesized pitching and yawing motion can be readily obtained by numerical methods. A modified trajectory linear theor...
متن کاملFabrication of κ-Carrageenan Fibers by Wet Spinning: Spinning Parameters
This study demonstrates the fabrication of κ-carrageenan fibers by a wet-spinning method and discusses three important spinning parameters: coagulation bath composition, spinning rate and post-spinning mechanical drawing. The as-spun fiber diameter decreased with KCl and ethanol concentration in the coagulation bath. In general, the ultimate tensile stress and elongation at break both increased...
متن کاملChemical “ Substances ” That Are Not “ Chemical Substances ”
The main scientific problems of chemical bonding were solved half a century ago, but adequate philosophical understanding of chemical combination is yet to be achieved. Chemists routinely use important terms (“element,” “atom,” “molecule,” “substance”) with more than one meaning. This can lead to misunderstandings. Eliminativists claim that what seems to be a baseball breaking a window is merel...
