Mathematics for Human Flourishing

Thanks seems not enough! I’ve been waiting for this words for so long… WE all have!!… This is an unforgettable moment full of Hope and Math 💞💞 …

The Mathematical Yawp

Why does the practice of mathematics often fall short of our ideals and hopes?  How can the deeply human themes that drive us to do mathematics be channeled to build a more beautiful and just world in which all can truly flourish?  I gave this Retiring Presidential Address at the AMS-MAA Joint Winter Meetings on January 6, 2017 at the end of my term as President of the Mathematical Association of America.  This speech will be published in The American Mathematical Monthly.  An audio recording and video recording are available.

Every being cries out silently to be read differently.
 ― Simone Weil, Gravity and Grace

Christopher is an inmate in a high-security federal prison not far from Atlanta.  He’s been in trouble with the law since he was 14.  He didn’t finish high school, had an addiction to hard drugs, and at age 21, his involvement in a…

Guateque en el Aftermath

Mientras término de preparar mi soñadoa EXPO – Taller Iluminación Matemática los dejo con este simpatiquisimo artículo!!…

Grandes matemáticos* reciben una invitación para una fiesta de celebrities en el Aftermath.  Fijaos en sus reacciones:

  • Cauchy asegura que se integrará sin problemas.
  • Hilbert  ha cerrado su hotel por esta noche y espera que nadie se aproxime demasiado a su espacio vital durante la fiesta.
  • Erdös se pregunta si los epsilones también han sido convidados. Él ha invitado a sus amigos, a los amigos de sus amigos, a los amigos de los amigos de sus amigos…

The Essence of the HLF, in One Story


Math with Bad Drawings

a dispatch from the fourth annual Heidelberg Laureate Forum

At most scientific conferences, you find a cross-section of ages: elder statesmen, rising stars, mid-career workhorses, maturing postdocs, and fresh-faced PhD candidates. The HLF brings together the two extremes: the most legendary of the legends, and the most bright-eyed of the youngsters.

What do such disparate groups have to talk about?

A lot, it turns out.


During the opening ceremony, Jean-Pierre Bourguignon—the president of the European Research Council—told a story from his own days as a young mathematician.

Why the Math Curriculum Makes No Sense

We finally start – motivated by – this article, our so long waited EDU Posts Series…

Math with Bad Drawings

What would you do, if you were designing high school math from scratch?

Well… probably not what we do now.


What in Noether’s name is going on here?

Why do we teach so many obscure technicalities, and so few practical facts?

Who the heck designed this monstrosity?

Nobody Designed Mathematics Education

I’ve come to believe that even this simple question—“who designed this?”—rests on a flawed assumption. The broad thing we call “the math curriculum” isn’t really “designed.” Rather, like all educational institutions and systems, it is shaped by a hailstorm of competing forces:


Over time, each of these parties tugs and prods at the curriculum, reshaping it to suit their needs. No single author writes the curriculum. Nor, even, do multiple authors reach a clear and coherent compromise. Instead, the curriculum is perpetually being nudged and tweaked, eroded and built up, by various actors who share no unified vision.
