Eric T. Bell 0. 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'elre of this series.
