The discussion revolves around finding a free font compatible with Word that includes the electric field symbol, which is described as a squiggly version of "E." Participants clarify that "E" typically represents electric field strength, while epsilon (ε) is often used for energy density, leading to confusion over the correct symbol. Suggestions include using the Equation Editor or alternative symbols like \mathcal{E}, but none seem to meet the original request. The conversation highlights the variability in symbol usage between physics and engineering texts, with some participants expressing frustration over the lack of available symbols in standard fonts. Ultimately, the discussion underscores the challenge of representing specific scientific symbols in word processing software.
