Learning about (machine) learning — Part I

Machine learning is everywhere these days, as we train computers to drive cars, play video games, and fold laundry. This intersects my lab’s research as well, which involves lots of computational image analysis (e.g.). Nearly everything my students and I write involves writing or applying particular algorithms to extract information from data. In the past … Continue reading Learning about (machine) learning — Part I

Berkeley astronomy news (rotten eggs part 2?)

I spent much of my undergraduate life in UC Berkeley’s Astronomy department. I was an astrophysics and physics double major for quite a while, and I spent countless hours working with our undergraduate-built rooftop radio telescope (shown), both helping build it and serving as a teaching assistant in the laboratory course we designed around it. … Continue reading Berkeley astronomy news (rotten eggs part 2?)

On the replication crisis in science and the twigs in my backyard

A long post, in which you’ll have to slog or scroll through several paragraphs to get to the real question: can we navigate using fallen sticks? These days we seem to be inundated with deeply flawed scientific papers, often featuring shaky conclusions boldly drawn from noisy data, results that can’t be replicated, or both. I … Continue reading On the replication crisis in science and the twigs in my backyard

On fungi and fabrics

A recent article in Physical Review Letters reports on “self-propelled droplet removal” from fibers — the authors designed hydrophobic fibers with the property that when water droplets grow and coalesce on them, the energy released by the coalescence flings the drops off the fibers. The underlying phenomenon is one we’ve all seen: two water droplets, … Continue reading On fungi and fabrics

In the future, my reviews will consist solely of one carefully picked emoji

There’s an interesting question about peer-review of journal articles that I’ve never seen addressed: How long does it take to review a paper? I don’t mean the three weeks or so between getting a request and submitting a review, but rather the time spent actually reviewing. In other words, how many hours does a reviewer … Continue reading In the future, my reviews will consist solely of one carefully picked emoji
