Franklin's Single Fluid | Origins Line | Benjamin Franklin | Unisex T-Shirt

Typographic layout representing Benjamin Franklin's groundbreaking "One-Fluid Theory" of electricity, proposed in the mid-18th century. Franklin hypothesized that electricity was a single, invisible fluid that permeated all matter. The key to the design is a premium, minimalist "formula sheet" structure that elegantly captures his core idea.

The design features three essential concepts:

1. Charge Conservation: An equation (or notation) illustrating that electric charge is neither created nor destroyed, only transferred. This fundamental principle is derived from Franklin's observation that rubbing two objects together created equal and opposite electrical states.
2. Fluid Transfer: Simple arrows or diagrams that show the movement of the electrical fluid between objects.
3. Terminology Notation: The elegant summary coined by Franklin: "Excess $\rightarrow$ Positive, Deficit $\rightarrow$ Negative."

This simple model, which preceded our modern understanding of electrons, established the standard sign convention for electric charge that is still used globally in physics and electrical engineering today. It was a monumental achievement in conceptual clarity and is a cornerstone of electrostatics. The design honors the scientist who defined the language of electricity.
