Mathematics and Science Journalist

Berkeley, California

I am an award-winning mathematics and science journalist whose work has appeared in Quanta, Nature, The Atlantic, New Scientist and many other publications, and has been reprinted in the 2010, 2011, 2016 and 2020 volumes of "The Best Writing on Mathematics."

### Karen Uhlenbeck, Uniter of Geometry and Analysis, Wins Abel Prize

March 19, 2019 — A founder of modern geometric analysis who produced “some of the most dramatic advances in mathematics in the last 40 years,” Uhlenbeck is the first woman to be awarded this top honor.### Math Duo Maps the Infinite Terrain of Minimal Surfaces

March 12, 2019 — A pair of mathematicians has built on an obscure, 30-year-old mathematical theory to show that soap-filmlike minimal surfaces appear abundantly in a wide range of shapes.### Jean Bourgain (1954–2018)

February 6, 2019 — Over the course of a wildly prolific career, Belgian mathematician Jean Bourgain would repeatedly enter some area, solve several of its outstanding problems and create an entirely new field of study in the process.### A Collector of Math and Physics Surprises

November 27, 2018 — Tadashi Tokieda lives in a world in which ordinary objects do extraordinary things. Jars of rice refuse to roll down ramps. Strips of paper slip past solid obstacles. Balls swirling inside a bowl switch direction when more balls join them. Yet Tokieda’s world is none other than our own. His public mathematics lectures could easily be mistaken for magic shows, but there’s no sleight of hand, no hidden compartments, no trick deck of cards.### Mystery Math Whiz and Novelist Advance Permutation Problem

November 5, 2018 — A new proof from the Australian science fiction writer Greg Egan and a 2011 proof anonymously posted online are now being hailed as significant advances on a puzzle mathematicians have been studying for at least 25 years.### Titans of Mathematics Clash Over Epic Proof of ABC Conjecture

Sept 20, 2018 — Two mathematicians have found what they say is a hole at the heart of a proof that has convulsed the mathematics community for nearly six years.### A Master of Numbers and Shapes Who Is Rewriting Arithmetic

August 1, 2018 — The 30-year-old math sensation Peter Scholze is now one of the youngest Fields medalists for “the revolution that he launched in arithmetic geometry.”### A Number Theorist Who Bridges Math and Time

August 1, 2018 — Akshay Venkatesh, a former prodigy who struggled with the genius stereotype, has won a Fields Medal for his “profound contributions to an exceptionally broad range of subjects in mathematics.”### First Big Steps Toward Proving the Unique Games Conjecture

April 25, 2018 — A paper posted online in January takes theoretical computer scientists halfway toward proving one of the biggest conjectures in their field.### The Infinite Primes and Museum Guard Proofs, Explained

March 26, 2018 — In January, I spoke with Günter Ziegler, one of the authors of Proofs From THE BOOK, a compilation of some of the most beautiful and elegant proofs in mathematics. The collection was inspired by the legendary mathematician Paul Erdős, who envisioned an infinite book in which God had written the perfect proof for each theorem.### In Search of God’s Perfect Proofs

March 19, 2018 — Paul Erdős, the famously eccentric, peripatetic and prolific 20th-century mathematician, was fond of the idea that God has a celestial volume containing the perfect proof of every mathematical theorem. “This one is from The Book,” he would declare when he wanted to bestow his highest praise on a beautiful proof.### Scant Evidence of Power Laws Found in Real-World Networks

February 15, 2018 — A paper posted online last month has reignited a debate about one of the oldest, most startling claims in the modern era of network science: the proposition that most complex networks in the real world — from the World Wide Web to interacting proteins in a cell — are “scale-free.”### A Mathematician Who Dances to the Joys and Sorrows of Discovery

November 20, 2017 — “Nadie te quita lo bailado.”(No one can take from you what you've danced.) For Federico Ardila, this Latin American expression epitomizes his approach to life and mathematics. It’s the driving force behind the parties he DJs in venues across the San Francisco Bay Area, where people dance till morning to the beats of his native Colombia. The dance floor is a place “where you have your freedom and you have your power, and nobody can take that away from you,” Ardila said.### Moonshine Link Discovered for Pariah Symmetries

September 22, 2017 — In 1892, the mathematician Otto Hölder posed a question that would occupy the field for more than a century: Is it possible to make a periodic table of all finite symmetry? The answer, to which hundreds of mathematicians have contributed, is yes. But the taxonomy that emerged from this monumental effort has prompted both enlightenment and head scratching.### How to Quantify (and Fight) Gerrymandering

April 4, 2017 — Powerful new quantitative tools are now available to combat partisan bias in the drawing of voting districts.### All Is Not Fair in Cake-Cutting and Math

October 7, 2016 — A pair of computer scientists recently settled one of the key questions in the theory of fair division: How can you allocate cake slices among a group of people in such a way that no one envies anyone else? Yet envy-freeness is just one of several competing notions of fairness. It’s all well and good to divide a cake in a way that won’t produce envy, but you might instead want to find an “efficient” allocation, one that can’t be improved for anyone without harming someone else.

I have been writing about mathematics and science for a popular audience for more than 20 years. A mathematician before I became a full-time journalist, I try to convey the essence of complex mathematical ideas to non-mathematicians, and give them a sense of the beauty and depth of mathematics.

I also enjoy plunging into topics far from my mathematical roots, and have written about fields such as economics, computer science, medicine, and biology — often as these fields relate to mathematics, but often simply for their own sake.

As a freelance journalist based in Berkeley, California, I have written for many publications, including Quanta Magazine, Nature, New Scientist, American Scientist, Nautilus, and Science News, for which I was the mathematics correspondent for several years. My work has also been syndicated in The Atlantic, Scientific American, Wired and other publications.

I was journalist in residence at the Mathematical Sciences Research Institute in Berkeley in 2002 and at the Simons Institute for the Theory of Computing at UC Berkeley in 2016. My work has been reprinted in the 2010, 2011, 2016 and 2020 volumes of "The Best Writing on Mathematics."

I received the 2021 Communications Award from the Joint Policy Board for Mathematics, which recognizes journalists and other communicators who, on a sustained basis, bring accurate mathematical information to nonmathematical audiences.

I am a graduate of the science writing program at the University of California, Santa Cruz, and I have a Ph.D. in mathematics from Stony Brook University.
