Lichtenberg refers to a phenomenon known as Lichtenberg figures, which are branching, tree-like patterns created by the discharge of electricity through an insulating material. These patterns can often be seen on the surface of materials like acrylic or wood when subjected to high-voltage electrical discharges. They are named after the German physicist Georg Christoph Lichtenberg, who first studied these patterns in the 18th century. In addition to the figures, Lichtenberg is also a name associated with various places and institutions, such as Lichtenberg, Berlin, a district in Germany. The name is used in different contexts, including streets, parks, and educational institutions, reflecting the influence of Lichtenberg's contributions to science and culture.
