Lichtenberg Figures: Fractal Skin Patterns After Lightning Strikes
Have you ever witnessed a natural phenomenon so striking, so intricate, and yet so fleeting that it seems to defy both beauty and destruction? Lichtenberg figures, those ephemeral lightning tattoos, are just that stunning visual manifestations of natures raw power, etched onto the very surface of our existence.
These mesmerizing patterns, resembling intricate fractal trees or branching lightning bolts, are far more than just a visual spectacle. They are, in essence, the "fingerprints" of electricity, captured in a moment of explosive energy. They are also incredibly rare, and usually disappear quickly.
First described in 1777 by German physicist Georg Christoph Lichtenberg, after whom they are named, these figures initially appeared as patterns in the dust on electrically charged surfaces. But, they've come to be understood as a type of branching electric discharge that sometimes appears on the surface or the interior of insulating materials. Lichtenbergs early experiments, conducted with a high-voltage electrostatic generator, involved applying an electric charge to a dielectric material. When the material was then sprinkled with a fine powder, the charge distribution became visible, revealing the fascinating patterns that now bear his name. They are natures way of visually representing the chaotic paths electricity takes when it surges through a material, offering a glimpse into the unseen dance of electrons.
Over the subsequent centuries, the study of Lichtenberg figures attracted the attention of a diverse array of scientists, experimenters, and artists. Figures such as Gaston Plant and Peter T., prominent researchers of the 19th and 20th centuries, delved further into the mysteries of their formation and characteristics. Their work, and the work of many others, has contributed to our understanding of these intricate patterns.
The science behind Lichtenberg figures is rooted in the principles of electrical discharge. When a high voltage is applied to an insulating material, it creates a powerful electrical field. This field causes the material to break down, creating pathways for electrons to flow. These pathways, which are often described as fractal-like, branch out in a complex and beautiful manner. The shape and density of these pathways depend on the voltage, the material's properties, and the surrounding environment.
Lightning strikes, for example, can leave behind Lichtenberg figures on the skin of individuals who survive these events. These are not burns, per se, but rather nonburn skin injuries, pathognomonic for lightning exposure. These figures manifest as temporary, branching red or purple patterns on the skin, tracing the path of the electrical discharge through the body. A witnessed lethal lightning strike of an adult male, for example, resulted in the appearance of numerous Lichtenberg figures on external examination of the body. Sectioning across multiple areas of the linear erythema in the figures showed no subcutaneous hemorrhage; this was later confirmed on histology. The electrical current traveling through the cardiovascular or nervous systems, or both, often causes such marks.
The medical community recognizes Lichtenberg figures as an important diagnostic tool in cases of suspected lightning injury. Because victims often present unconscious or are unable to recall the incident, the presence of these figures can provide critical evidence of lightning exposure. Furthermore, the patterns themselves can offer insights into the path the electrical current took through the body, helping medical professionals assess the extent of the damage.
But it's important to note that these are not permanent tattoos. These electrical arborescences are ephemeral marks of natures power and danger. The intricate patterns, while undeniably beautiful, fade over time, often disappearing within days or weeks. The electrical energy, and the heat that accompanies it, causes blood vessels to burst, potentially creating something called a Lichtenberg figure on your skin. The bacterial permeability increasing protein and fibrinogen components (beta and gamma chains) and other upregulated proteins are also a contributing factor. Some studies show that the patterns are recognized as fractals. Most victims are also left with lifelong injuries.
The beauty of Lichtenberg figures lies not just in their visual appeal but also in the scientific understanding they provide. They offer a window into the unseen world of electricity, revealing the complex dance of electrons at a microscopic level. They are also a testament to the power of nature and the ability of science to illuminate its mysteries. The patterns that are created are known to be examples of fractals.

The patterns generated are recognized as fractals. The danger involved makes it undesirable to have these scars. Nonetheless, the uncommon beauty they possess is undeniable. As fascinating as they are, Lichtenberg figures are a stark reminder of the power of electricity and the delicate balance between beauty and destruction.
