  • For a better cup of coffee, look to physics

    Researchers from Penn have found new cost-effective ways to make a great cup of pour-over coffee using fewer beans. Their findings could potentially provide insights into similar systems such as waterfalls and surface erosion.

    In the Arnold Mathijssen lab, researchers used a gooseneck kettle, coffee grinder, and a pour-over setup alongside precise measurements and high-speed analysis to study the fluid dynamics and mechanics of coffee brewing to uncover ways to maximize flavor with fewer grounds. The findings could help researchers understand fluid dynamics.

    In Senegal, the ambitious Dakar Greenbelt project seeks to create an extensive network of ecological infrastructure in and around the city to sustainably address environmental concerns and enhance urban life. With support from David Gouverneur and Ellen Neises, Ph.D. candidate Rob Levinthal in the Weitzman School of Design led two courses that included a field trip to Dakar, that culminated in students presenting their visions for parts of the Greenbelt.
