In Conversation with Judith Schaecter: Art, Science, and the "Super/Natural"
Thursday December 11, 2025
Acclaimed stained glass artist Judith Schaechter will discuss her immersive installation "Super/Natural"—a luminous, three-tiered cosmos rendered in glass. The work draws on her residency at the Penn Center for Neuroaesthetics, incorporating insights from biophilic design and the rich history of women’s contributions to botanical art. Through the lens of her own work, she will consider where the disciplines of art and science intersect, where they diverge, and whether true objectivity is even possible in a world observed from within one's own mind.

Beyond Linnaeus: Pennsylvania Paleontology and the Surprising Power of a (Biological) Name with Dr. Jason Downs
Thursday February 9, 2023
In 1735, Carl Linnaeus established the foundation for what has become the most enduring system of biological naming. However, his rank-based organizational system – kingdom, phylum, class -- is rooted in pre-evolutionary thinking. In this talk, Dr. Jason Downs will explore the specific ways in which a more modern naming practice can reshape our understanding of the history of life.
