Hubbard is a former student of [[Harvard University]]'s infamous [[Math 55]], where he famously struggled initially because he "just didn't know proofs," a somewhat shocking fact considering his eventual mathematical success. He later returned to [[Harvard]] to teach that same class. However, Hubbard garnered a rather profound distaste for [[Math 55]]'s method of teaching proofs largely centered on [[algebra]]ic [[mathematical induction|induction]]. In response, he wrote a book entitled ''Vector Calculus, Linear Algebra, and Differential Forms: A Unified Approach'', on which his wife Barbara is listed as a co-author. At [[Cornell University]], he routinely teaches Math 2230 & 2240, classes specifically structured around this same text. When asked how well these classes correspond to [[Math 55]], he responded: "This class may indeed be somewhat easier than [[Math 55]], albeit perhaps covering slightly more material."


== Writing ==
Hubbard is known throughout the [[Cornell]] community for his very relaxed style of teaching. He often starts class late, after a period of conversing with students on a variety of more personal, informal topics, such as his hobby of collecting and purveying various local varieties of [[mushrooms]] found across campus, easily citing the given [[binomial nomenclature]] for each [[species]].

John Hamal Hubbard (born October 6 or 7, 1945) is an American mathematician and professor at Cornell University and the Université de Provence. He is known for the mathematical contributions he made with Adrien Douady in the field of complex dynamics, including a study of the Mandelbrot set. One of their most important results is that the Mandelbrot set is connected.
