Manufacturing of fiber optic glass in microgravity is seen as a better way to make glass fibers with fewer imperfections that scatter light signals. Credit: NASA NASA plans to study the manufacturing ...

Spin glasses are physical systems in which the small magnetic moments of particles (i.e., spins) interact with each other in a random way. These random interactions between spins make it impossible ...
