The Unbearable Literalism of Being a Mathematician or Why I Hate Literary Disclaimers
Mathematicians, like kleptomaniacs, take things literally. This is the story of how I finally snapped and wrote a strongly worded blog post about why literary disclaimers annoy me.

A Belated Apology to Mozart and Modular Arithmetic
What do Mozart and modular arithmetic have in common? I used to think I didn't like them. I'm sorry, Mozart and modular arithmetic. Please forgive me.

A Few of My Favorite Spaces: Cantor's Leaky Tent
The mathematical space called Cantor's leaky tent is connected but just barely: remove one point, and the whole thing falls apart.

When the Mona Lisa Is NPHard
Bob Bosch and Tom Wexler have developed a new way to make your favorite masterpieces into connectthedots puzzles. All you need is a little bit of quantification and a lot of computing time.

A Few of My Favorite Spaces: The Topologist's Sine Curve
The topologist's sine curve is a classic example of a space that is connected but not path connected: you can see the finish line, but you can't get there from here.

A Few of My Favorite Spaces: Fat Cantor Sets
Last month, I wrote about the Cantor set, a mathematical space that is an interesting mix of small and large. It's small in the sense that its length is 0.

The Cantor Function: Angel or Devil?
When you're looking at it, it just stays there, constant and still. But if you turn your back for just an instant at a point in the Cantor set, the function grows impossibly quickly.

A Few of My Favorite Spaces: The Cantor Set
Last month, I wrote about the Base, a website that serves a similar function to the book Counterexamples in Topology. I'm teaching a topology class this semester, and it's been fun to revisit some good counterexamples.

What’s so Great about Continued Fractions?
The more I learn about continued fractions, the more enamored I am with them. Last week, when I wrote about how much better continued fractions are than the arbitrary decimal digits we usually use to describe numbers, I mentioned that continued fractions tell us the "best approximations" of irrational numbers.

Don’t Recite Digits to Celebrate Pi. Recite Its Continued Fraction Instead.
The digits of pi reciting contest is an alltoocommon Pi Day event. And as this year is a onceinacentury confluence of month/day/year with the first few decimal digits of pi, we might be in for more of those than usual.

Uber, but for Topological Spaces
So it's cold and rainy, and you're up a little too late trying to figure out why that one pesky assumption is necessary in a theorem. Wouldn't it be nice if you could just order up a space that was path connected but not locally connected?
