“Concinnitas” was a term used by 15th-century scholar and architect Leon Battista Alberti to describe beauty in architecture, which he believed existed when — and only when — parts of a building cohered to a harmonizing whole. It was also used to name The Concinnitas Portfolio, to which Professor Pau Atela responded in his Re(Creations) and MathStudio. Both the portfolio and Atela’s work will be displayed at the University Museum of Contemporary Art at UMass until Dec. 9.
