Mathematician Claims New Yorker Defamed Him

An anonymous reader writes, "Last month the New Yorker ran the article 'Manifold Destiny' (slashdotted here), by Sylvia Nasar, author of 'A Beautiful Mind.' Now a renowned Harvard mathematics professor, Dr. Shing-Tung Yau, is claiming the article defamed him. His attorney wrote the New Yorker a letter (PDF) threatening that Yau will have 'no choice but to consider other options' if Nasar, her co-author, and the New Yorker fail to undo the damage done."
