Bell 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'el: re of this series.
