We mentioned above that Johann's doctoral dissertation was on a topic in medicine, but it was really on an application of mathematics to medicine, being on muscular movement, and it was submitted in 1694. Johann did not wish to follow a career in medicine however, but there were little prospects of a chair at Basel in mathematics since Jacob filled this post.
Me eespool mainitud Johann's doktoritöö oli teema meditsiinis, kuid see oli tõesti taotluse kohta matemaatika on ravim, mida on lihaste liikumine, ja see oli esitatud 1694. Johann ei soovi järgida karjääri meditsiinis siiski, kuid seal oli vähe väljavaateid juhatusel Basel matemaatika, sest Jacob täidetakse see ametikoht.
