Mathematician Maryam Mirzakhani is the first woman and first Iranian to be awarded the Fields Medal!
The Fields Medal is one of the highest honors granted in math. Every four years the medal is awarded at the International Congress of the International Mathematical Union to two, three, or four mathematicians under the age of 40. Along with the Abel Prize, it is considered “the mathematician’s Nobel Prize.”
Mirzakhani’s work focuses on Riemann surfaces and their moduli spaces and connecting aspects of differential geometry, complex analysis, and dynamical systems. Currently she is working on developing the understanding of billiards and translation surfaces with fellow mathematician Alex Wright. A fantastic overview of her life can be found in this article.
The Fields Medal was also awarded to Artur Avila (dynamical systems), Manjul Bhargava (number theory), and Martin Hairer (stochastic differential equations).

I want a math themed tattoo. But do I get an infinity sign, a delta, Pascal’s triangle, Euler’s identity, or Euler’s formula?!
I vote for one of the platonic solids
Three Different Stellations of the Rhombic Triacontahedron
These polyhedra are selected from the the (long) stellation-series of the rhombic triacontahedron. Stellating polyhedra, and manipulating them in other ways, is easy with Stella 4d, which you can try as a free trial download here: www.software3d.com/Stella.php.
