On the motivic Thom isomorphism, by Jack Morava
The existence of a good theory of Thom isomorphisms in some rational category
of mixed Tate motives would permit a nice interpolation between ideas of
Kontsevich on deformation quantization, and ideas of Connes and Kreimer on
a Galois theory of renormalization, mediated by Deligne's ideas on motivic
Galois groups.
