Prompt
Create an image of Stanislaw Ulam, a middle-aged man with a slender build and bespectacled, sitting at a desk with papers and mathematical equations scattered around him, wearing a suit and tie, with a thoughtful expression on his face, in a style reminiscent of 1950s or 1960s portrait photography. The background should be a warm, muted color, possibly with some mathematical symbols or diagrams subtly integrated into the design. The overall mood should be one of intellectual intensity and contemplation.
