John Hamal Hubbard was born on October 6 or 7, 1945 (the actual date is unknown). He is an American mathematician who is currently a professor at Cornell University and the Université de Provence.

Expertise

He is well 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.

Background

Hubbard graduated with a Doctorat d'État from Université de Paris-Sud in 1973 under the direction of Adrien Douady; his thesis was entitled Sur Les Sections Analytiques de La Courbe Universelle de Teichmüller and was published by the American Mathematical Society. Hubbard has a variety of mathematical interests ranging from complex analysis to differential geometry.

He has written many influential papers on complex dynamics, and he has written several books.

Legacy

In 2006, he completed the first volume of a series devoted to Teichmüller theory and applications to four revolutionary theorems of William Thurston.

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 successes.

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 algebraic 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."

Hubbard is known throughout the Cornell community for his very relaxed style of teaching.
