o. Heaviside Mathematics is a tool for thought. A highly necessary tool
in a world where both feedback and non- linearities abound. Similarly,
all kinds of parts of mathematics serve as tools for other parts and for
other sciences. Applying a simple rewriting rule to the quote on the
right above one finds such statements as: 'One service topology has
rendered mathematical physics .. .'; 'One service logic has rendered
com- puter science .. .'; 'One service category theory has rendered
mathematics .. .'. All arguably true. And all statements obtainable this
way form part of the raison d'etre of this series.
