One of the world's most prolific
mathematicians in the field of
Mechanics. His career dates from
Stalinist
USSR, and he is still active at the turn of the 20th century. One of his earliest achievements is the
Kolmogorov-Arnold-Moser Theorem in
dynamics. Arnold's writing style mixes rigorous and abstract mathematics with informal, almost conversational prose. Arnold espouses a geometric approach to mathematics in general, and mechanics in particular. His opinions on the subject can be found on the web.
