Our compost ecosystem: Breaking down Vermont’s food scraps

Every year, the folks at MassMutual Life Insurance get together for “Data Days for Good”, where team members work to help a local agency or organization with a data science project. Through a research partnership between the University of Vermont Complex Systems Center and MassMutual, I learned about the Data Days for Good initiative, and in the spirit of that event, I turned …

Divergence, derailment, and diversity of #BlackLivesMatter and #AllLivesMatter discussions

Hashtags on Twitter have become well established as a way for people to come together around seemingly any topic. Hashtags allow us to collectively tell jokes (#IceCreamAMovie), mark celebrations (#HappyNewYear), refer to sports (#SuperBowl51, #IPL),  and engage in (or enrage about) politics (insert your hashtag here). Hashtags are clickable catchphrases. For social and …

A bird’s-eye view of #WomensMarch

On January 21st, 2017, the Women’s March on Washington gathered enormous crowds in collective protest of the newly inaugurated President of the United States, Donald Trump. Meanwhile on Twitter, people used the hashtag #WomensMarch to magnify and respond to the on-the-ground movement. Here at the Computational Story Lab, we found ourselves wondering about a few things. How …

Connecting every bit of knowledge

What is the shape of all knowledge?  How has knowledge grown over time?  Can we anticipate ways in which knowledge will grow? Knowledge is certainly hierarchically structured but it’s also richly scaffolded and networked with concepts and ideas linking within and across domains. We can attempt to answer some of these questions by computationally exploring the Network of …

How our storytelling nature means we deeply misunderstand the mechanics of fame (and much else…)

Should the Mona Lisa be our most famous painting? Was Harry Potter destined to (repeatedly) sweep the globe? What would happen to everyone and everything famous if we ran the experiment that is our world over again? Find out why fame is truly unpredictable, how it lives and dies entirely in our social stories, and why “... there is no such thing as fate, only the story of …

If you're still here, here's the blurb from the site's about page: Happiness: It’s what most people say they want. So how do we know how happy people are? You can’t improve or understand what you can’t measure. In a blow to happiness, …

A data-driven study of the patterns of life for 180,000 people

Here at the Computational Story Lab, some of us commute by foot, some by car, and a few deliver themselves by bike, even in the middle of our cold, snowful Vermont winter.  Occasionally, we transport ourselves over very long distances in magic flying tubes with wings to attend conferences, to see family, or for travel.  So what do our movement patterns look like over time?  Are …

Who will your friends be next week? The link prediction problem

Sitting in the student center of our university, I am surrounded by hundreds of students enjoying their lunch and socializing. They’re strengthening (and in some cases weakening) their social ties. Given the ability to observe this social network over time, we would see that some relationships flourish, while others disappear altogether. This situation is not unique to …

What’s the most important theorem?

Mathematical truths are organized in an incredibly structured manner. We start with the basic properties of the natural numbers, called axioms, and slowly, painfully work our way up, reaching the real numbers, the joys of calculus, and far, far beyond. To prove new theorems, we make use of old theorems, creating a network of interconnected results—a mathematical house of …
