Graphite is an electric conductor, consequently, useful in such applications as arc lamp electrodes. It can conduct electricity due to the vast electron delocalization within the carbon layers (a phenomenon called aromaticity). These valence electrons are free to move, so are able to conduct electricity.
White is the result of reflection of all colors. Snow and snowflakes are ice crystals mixed with air molecules. The air gaps between crystals, along with the crystals’ complex shapes, bounces the light beams around so much that all the wavelengths eventually get reflected out, giving it a white color.
Throughout scholarship multiple theories have been posited in an attempt to identify the group at Qumran (yahad). To date, the most widely accepted theory among scholars is the Essene hypothesis; that the community at Qumran associated with the scrolls can be best identified as the Essenes. Evidence for this notion primarily stems from accounts by Josephus, Philo of Alexandria, and Pliny the Elder. Though many scholars have suggested alternative identifications for the yahad, the Essene hypothesis remains the dominant theory in the field.
Cats, dogs, and many nocturnal creatures appear to have glowing eyes because the back of their eyeballs include a special reflective layer called the tapetum lucidum. This helps animals (cats in this case) see better in low light by working like a mirror on the retina to reflect the light back through the eyes.
