2 Pallas a different name, 智神星 "zhìshénxīng" (which means "the wisdom-god(dess) star"), even though the Chinese call the goddess Pallas herself by the Greek name (帕拉斯 "pàlāsī"). The stony-iron Pallasite meteorites are not connected to the Pallas asteroid, being instead named after the German naturalist Peter Simon Pallas. The chemical element palladium, on the other hand, was named after the asteroid, which had been discovered just before the element. As with other asteroids, the astronomical symbol for Pallas is a disk with its discovery number, ②. It also has an older, more iconic symbol, ⚴ () or sometimes 🜍 (). Pallas has
Warburg element There are two special conditions of finite-length Warburg elements: the Warburg Short (W) for a transmissive boundary, and the Warburg Open (W) for a reflective boundary. This element describes the impedance of a finite-length diffusion with transmissive boundary. It is described by the following equation: This element describes the impedance of a finite-length diffusion with reflective boundary. It is described by the following equation: Warburg element The Warburg diffusion element is an equivalent electrical circuit component that models the diffusion process in dielectric spectroscopy. That element is named after German physicist Emil Warburg. A Warburg impedance element can be difficult
