Prompt
Create an image of a 19th-century British gentleman with a dignified beard, sitting in a ornate armchair, surrounded by scientific instruments and papers, with a thoughtful expression. He is wearing a formal suit, a white shirt, and a tie. In the background, there is a bookshelf filled with scientific texts and a large window with a view of the city. The gentleman is holding a pen and a piece of paper, as if he is working on a mathematical problem. The image should convey a sense of intelligence, curiosity, and authority. The style should be realistic and formal, suitable for a prominent figure in the fields of physics, mathematics, and engineering. The subject is Sir William Thomson (Lord Kelvin), a renowned physicist, mathematician, and engineer, and the image should reflect his profession and social status.
