As the Covid-19 pandemic continues, the proliferation of models of the spread of the virus rivals the spread of the virus itself. Looking at these models is dizzying, and their accuracy so far, especially with respect to heterogeneity across regions, is unimpressive. Of course, modeling an ongoing pandemic is hard, but recently a more fundamental … Continue reading Known and unknown pandemic models
This evening, the American Physical Society suddenly cancelled its largest annual conference, the March Meeting, the day before it was to start. I’m one of the 10,000 physicists who will now not be spending the coming week in Denver. The cancellation is due to fears of the coronavirus. Some would say the caution is warranted; … Continue reading A Coronavirus-Cancelled Conference

I was reminded of this recently by an excellent paper comparing the impact of small and large research groups on science. The two papers should perhaps be … Continue reading Science, Small Groups, and Stochasticity
The U.S. National Science Foundation ran an interesting call for proposals recently called the “Idea Machine,” aiming to gather “Big Ideas” to shape the future of research. It was open not just to scientists, but to anyone interested in potentially identifying grand challenges and new directions. I expect that most of the submissions will be … Continue reading What’s the big idea? Science!
