John Nash Quote

So as it happened, as soon as I heard in conversation at M.I.T. about the question of the embeddability being open, I began to study it. The first break led to a curious result about the embeddability being realizable in surprisingly low-dimensional ambient spaces provided that one would accept that the embedding would have only limited smoothness. And later... the problem was solved in terms of embeddings with a more proper degree of smoothness.
