で、数学が面白くなったんだ
東大受験勉強時代は、数学者になる予定じゃなかったのに・・

しかし、よくこんなものが
独学で読めますね・・ｗ

HOMOLOGY 1963
DR. SAUNDERS MAC LANE. MAX MASON DISTINGUISHED SERVICE
Preface
In presenting this treatment of homological algebra, it is a pleasure
to acknowledge the help and encouragement which I have had from
all sides. Homological algebra arose from many sources in algebra and
topology. Decisive examples came from the study of group extensions
and their factor sets, a subject I learned in joint work with OTTO SCHILLING. A further- development of homological ideas, with a view to their
topological applications, came in my long collaboration with SAMUEL
EILENBERG; to both collaborators, especial thanks. For many years
the Air Force Office of Scientific Research supported my research
projects on various subjects now summarized here; it is a pleasure to
acknowledge their lively understanding of basic science.
