Gottschall, C. (2019): Logic Calculator: Truth-Tables (featuring a purple monster and a psychic duck) (Software)

    Abstract:

    This truth-table calculator for classic logic shows, well, truth-tables for propositions of classical logic. Optionally showing intermediate results, and featuring a purple monster and a duck, it is one of the better instances of its kind. If the user leaves the input field empty, the psychic duck will read the proposition from the user's mind (this feature is experimental at this time). The truth-table calculator is online at the following URL: https://www.erpelstolz.at/gateway/TruthTable.html
