Guest Post: A Mathematical Mastermind Gets His Head Examined

On a December day a few years ago, John Horton Conway settled in for an interview at the office of neuroscientist Sandra Witelson. Conway wasn’t there for an appointment proper, but rather to provide fodder for Witelson’s ongoing research on scientifically minded brains. All the same, he’d braced himself for an arsenal of standard neuropsychological […]

Guest Post: Why humans suck at earthquake preparedness

Driving through my hometown in Kentucky, I admire the old-growth oaks, the spires and stained glass of Victorian era homes, and the tall brick chimneys. Then I think about how they would crumble in an earthquake. Ever since moving to the west coast, I size up the earthquake safety of every place I go: I […]

Guest Post: Science Fail

When I was in 4th grade, my teacher gave everyone in class an ice cube. Our task, she said, was to keep it from melting for as long as possible. In a room full of 10 year olds, that task turned into a heated competition. But I wasn’t worried. I’d had a stroke of insight: […]

Guest Post: How the Bolivian Navy Became Landlocked

Cassandra wrote a post about the landlocked Bolivian navy in which she explained, in passing, that Bolivia once had a coast but lost it to Chile in the War of the Pacific.  One of the comments on that post, by guest poster Nick Suntzeff, was a post in itself and we thought you’d like to […]

Guest Post: the Grandmother Hypothesis

Recently I’ve started seeing examples of those much-mocked New York Times trend stories that are not about Millennials, the way the trendiest trend stories usually are. In the articles I’ve been noticing, the trend-setters are Baby Boomers — who are, according to the Times, relocating to New York City to help raise the grandkids. Now […]

Guest post: Water Unbound

It has been raining for three days now, really raining, the kind of rain that can only occur in a place that receives upwards of 7 meters of rain a year. Three days ago, water began pouring out of the sky the way it might during a tropical afternoon storm or a monsoon — a […]

Guest Post: The Lords of Yesterday

As my husband and I drove into Ouray, Colorado recently, we both gasped. The red-grey cliffs of 14,000-foot mountains cradle the old mining town, with waterfall lacework tracing down the mountainsides — one of the most gorgeous spots on Earth. But it was the stream tumbling through the valley we were gasping at: It was […]

I’ll Miss You Summer

My son’s new school supplies shine too brightly in the corner of my office. It’s the standard fare: glue sticks, soon to be dried out felt pens, a rainbow of highlighters, a cheap pencil sharpener made in China. The exercise books lay crisp and waiting to be filled with vocabulary tests and paragraphs about summer […]
