For any fiat 2-category C, we show how its simple transitive 2-representations can be constructed using co-algebra 1-morphisms in the injective abelianization of C. Dually, we show that these can also ...

The project explores the effects of spatial representations of number magnitude on children's learning of advanced arithmetic strategies, a key predictor of math achievement. A series of studies will ...

Two breakthroughs in mathematics could reshape how researchers understand symmetries in nature and the behavior of complex systems. These advances, led by Pham Tiep, a professor at Rutgers University, ...

Here's the thing about math that nobody tells you: it's less about memorizing formulas and more about knowing which tools to reach for. By fourteen, students should have a problem-solving toolkit that ...
