abstract:Professor Cuthbert Calculus (, meaning "Professor Tryphon Sunflower"), is a fictional character in The Adventures of Tintin, the comics series by Belgian cartoonist Hergé. He is an absent-minded professor and half-deaf physicist who invents many sophisticated devices used in the series, such as a one-person shark-shaped submarine, the Moon rocket, and an ultrasound weapon.
His grandfather, Auguste, broke high altitude records in the '30s by designing a balloon with a pressurized cockpit, and later became the inspiration for ProfessorCalculus in the Tintin comics.
They regularly drop in on Mr Gold, who quizzes them closely, his wild greying locks and well-stuffed shirt pocket giving him the air of a rumpled physics professor expounding an exotic retail calculus.
