This course brings together two distinct scientific disciplines—quantum physics and marine biology. Although they describe very different worlds, both fields captivate us for remarkably similar reasons: each reveals hidden realities that escape everyday perception and intuitive understanding. In unexpected ways, both disciplines also challenge and expand our understanding of memory.

The course consists of two parts. The first part (quantum physics) will be taught by Tanja Traxler, and the second part (marine biology) by Bettina Riedel. Participation in both parts is required for the successful completion of the course.

Part 1: Since the foundation of quantum physics, this domain of modern science has—despite its many successes—struggled to provide intuitive understanding. While the mathematical formalism of quantum mechanics is extraordinarily successful and precise, physicists continue to grapple with how to intuitively conceptualize space, time, and reality within the framework of quantum theory. John S. Bell famously referred to such vaguely defined notions as “quantum unspeakables,” a category that included, among other things, the concept of measurement. The first part of this course will address both speakables and unspeakables in quantum physics, with a particular focus on the concepts of matter, measurement, and memory.

Part 2: This thematic block examines the ‘unknown’ ocean and the enduring fascination it holds for humans, exploring this topic from various perspectives. One lecture [“Unspeakables”] represents a journey through the history of perception, collection and representation of real and mythical sea creatures in science, art and culture, bridging the gap between early naturalism and modern biology. Another lecture [“Quantum”] will explore various marine habitats and ecosystems, their inhabitants, and their living conditions. Finally [“Memory”], we will take a closer look at the most significant human-induced changes to the ocean and how these are affecting marine life and vital ecosystem services.

To successfully complete this course, participation in both parts taught by Tanja Traxler and Bettina Riedel is required. In addition to regular attendance and active participation, each participant will be asked to contribute to a group presentation, including a handout (1-2 pages) related to one of the topics covered in the lectures. In the final session, a concluding discussion will take place, in which each participant is expected to share their perspective on the themes explored throughout the seminar.
