A story is told of a famous violinist who was to perform at a concert hall of world renown. As he stood before the packed house that night and played his violin, he mesmerized the audience with his prowess and skill. As he lifted his bow off the string on his final note, the hall erupted with thunderous applause and he was given a standing ovation. He looked at the crowd for a moment and walked off the stage only to return to render an encore performance. To the amazement of the masses gathered there that night, his encore performance was even more beautiful and flawless than the first.
Somewhere in the beginning of each day, you probably find yourself looking at your reflection in the mirror. Many of us never give a second thought as to how that reflection is produced. All surfaces reflect some light, but only a special type of surface reflects light in such a way that it can form a mirror. In 1835 German chemist Justis von Liebig devised a process for coating plates of glass with metallic silver. This was the beginning of the mirror as we know it today and helped it become a common household item.
