Thank you for your quick response! I thought it would be treated as a word sign expression, given the (345) character, yet the positions are not included in Table 18 (b) and (c). I also take this to mean that a dot 3 will not be needed between this notation and another word sign expression.
Thank you, Lindy, for your quick, informative response. The print copy (University Physics with modern Physics, Bauer & Westfall, page 266) does call this symbol "script theta." Thank you for so clearly covering both possibilities! Karen
Welcome to this forum and thank you for your question. This logic negation symbol meaning "not" is not listed in the Nemeth Code. You may substituted the tilde for this symbol (the tilde also means "not" in logic) as long as the tilde does not appear elsewhere in this transcription. You must explain the substitution in a transcriber's note. If this is not an option, devise a symbol. Explain in a transcriber's note and list the transcriber-devised symbol on the special symbols page.
