What are Lichtenberg figures?


[By Staff reporters]

Lichtenberg figures” are branching, tree-like patterns that are created by the passage of high voltage electrical discharges along the surface, or through, electrically insulating materials (dielectrics).

The first Lichtenberg figures were actually 2-dimensional “dust figures” that formed when airborne dust settled on the surface of electrically-charged plates of resin in the laboratory of their discoverer, German physicist  Georg Christoph Lichtenberg (1742-1799).

Professor Lichtenberg first observed this in 1777, demonstrated the phenomenon to his physics students and peers, and reported his findings in his memoir (in Latin): De Nova Methodo Naturam Ac Motum Fluidi Electrici Investigandi (Göttinger Novi Commentarii, Göttingen, 1777). The English translation of the title is, “Concerning the New Method Of Investigating the Nature and Movement of Electric Fluid”.
