This is my first attempt to communicate with the ChatGPT4 on the caloric theory of heat. ChatGPT4 reacted promptly with a good overview of this topic. ChatGPT4 during our half hour conversation brought a new view to this topic with some unknown references to the author of this contribution. ChatGPT4 can be promising support to improve the literature search and can offer new ideas before the experimental work and during the preparation of the manuscript. However, the “classical preparation” still plays the dominant role.
