Uses a requence of chiken wire models built by Charles Pugh and a discusion of the problem of turning a sphere inside out by passing the surface through itself without making any holes or creases. Mathematicians belived this was insoluvable until 1958 when Stephen Smale proposed the present to the problem. This homotopy was developed earlier by the blind mathematician Bernard Mann. Different color sequences by computer animation reveal the continuous motion of the sphere. Bahan rosak (Lupus)
