Comic. [A person and a second person with a ponytail sitting at a table with a screen showing a soccer game behind them.] PERSON 1: They could be in trouble. Over the last 36 years, they’ve gone 0 for 2 when they’ve scored in the 37th minute to lead 2-1 against a team whose country comes before theirs alphabetically.

The Higgs mechanism was proposed in 1964 by three independent teams. But here is the puzzle🤔: the "disruption index" says Higgs's paper is among the least disruptive ever. So what is going on? In our new paper, just out in #ScienceAdvances, we take up this puzzle: doi.org/10.1126/scia... 👇 1/7

An embedding-based disruption measure not only robustly captures disruptive works but also reveals simultaneous discoveries.
