is a frequent source of humour in his interactions with other people, as he often repeats back what he thinks he has heard, usually in the most unlikely words possible. Additionally, he often diverts the subject of a conversation by responding to a misinterpreted remark. For example, "But I never knew you had...." leads Calculus to respond, "No, young man, I am not mad!" In the same book he believes that Tintin and Haddock are talking about his sister, before remembering a few moments later that he does not have a sister. He is not perturbed by his handicap, even if it is a source of deep frustration to his friends. He himself does not admit to being near-deaf and insists that he is "only a little hard of hearing in one ear."
In the course of the ''Moon'' books, however, Calculus leads a team of scientists and engineers working on a major rocket project, motivating him to adopt an
ear trumpet, and later a
hearing aid

, and for the duration of the adventure he has near-perfect hearing. This made him a more serious character, even displaying leadership qualities that had not been shown before or since. However, after completing the journey to the Moon, Calculus discarded his hearing aid, forcing his friends to readjust to his hearing impairment (aside from one panel in ''The Castafiore Emerald'', when Tintin is seen speaking to him through his ear-trumpet); this restored the humour surrounding him, though it could be that he finds his deafness useful since it enables him to focus on his work (something useful for ''
The Calculus Affair'', since he was referencing ultrasonic sound).
Calculus maintains a laboratory at
Marlinspike Hall, in which he conducts various experiments. He is fairly protective of his work, on occasion hiding his scientific endeavours from Tintin and Haddock (which gets him into trouble in ''
The Calculus Affair''). His lab is also stripped of all its apparatus in the same book. On an earlier occasion, during his efforts to find an antidote to Formula Fourteen in ''
Land of Black Gold'', Calculus almost destroyed half of Marlinspike in an explosion.
Although generally a mild-mannered (if somewhat oblivious) figure, Calculus flies into an uncharacteristic rage if he feels insulted or ridiculed. He is especially provoked if he ever hears Haddock (or anyone else) call him a "

'' Calculus is shown with a frown for a few moments when he thinks that the Captain lied to him that Tintin had gone for a row, when Tintin actually was diving to search for treasure. Despite his gentle nature, Calculus is rather sensitive about his work and does not appreciate being ridiculed or belittled for his scientific efforts.
In spite of all this, his friends stick by him come what may. Haddock invited him to stay at
Marlinspike Hall after Calculus discovered it is the captain's ancestral home and bought it in his name thanks to money he had earned through selling the patent for his shark-submarine. He did this because Haddock and Tintin had provided him with the opportunity to test the submersible when they were searching for

: "Calculus is a reduced scale Piccard, as the real chap was very tall. He had an interminable neck that sprouted from a collar that was much too large... I made Calculus a mini-Piccard, otherwise I would have had to enlarge the frames of the cartoon strip." The Swiss physics professor held a teaching appointment in Brussels when Hergé spotted his unmistakable figure in the street. In ''
The Castafiore Emerald'', Bianca Castafiore mentions that Calculus is "famous for his balloon ascensions", an ironic reference to Piccard.

plumber.
In contrast to his unquestionable scientific merits, Calculus is a fervent believer in

Calculus's introduction appears to have supplied Hergé with the bizarre nature he wished to portray in a man of science. Other figures of high education were shown as more stable and level-headed. The members of the archaeological expedition who fall victim to ''
The Seven Crystal Balls'' show no apparent signs of eccentricity. The most prominent member of this group is Calculus's friend Hercules Tarragon, with whom he attended

Marlinspike Hall in ''

botanic experiments lead him to create a new variety of
