One service mathematics has rendered the 'Et moi, .. ., si j'avait su
comment cn rcvenir, human race. It has put common sense back. je n'y
serais point aile.' where it bdongs, on the topmost shelf neAt Jules
Verne to the dusty canister labelled 'discarded non- sense'. The series
is divergent; therefore we may be Eric T. Bdl able to do something with
it. 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 a, rguably true. And all statements
obtainable this way form part of the raison d'etre of this series.
