WebTheorem 1 (The Dold-Thom theorem). There is an isomorphism Hi(X) ∼=πi SP(X). (To apply SP to Xwe must give it a basepoint; but any basepoint will do.) The Dold-Thom is not, however, merely of interest as a technical curio connecting homology and homotopy theory. Recent developments have given it a much deeper significance.
