Idea

The fact that for a manifold XX of dimension kk, then for any embedding ι:X n\iota \colon X\hookrightarrow \mathbb{R}^n (which exists by the Whitney embedding theorem) the Thom space X νX^{\nu} of the normal bundle ν\nu behaves like a dual to X +X_+ under smash product of pointed topological spaces.

Under passing to suspension spectra this becomes Atiyah duality in stable homotopy theory.
