Beyond Bohm 2025, Part 2 – The impact of (quantum) materials on the development of humanity and the shaping our future

The impact of (quantum) materials on the development of humanity and the shaping our future

with Saskia F. Fischer

Saturday August 9
9:00am PDT  | 12:00pm EDT  | 5:00pm BST  |  6:00pm CEST 
2-hour session.

The session is live and you will be sent the RECORDING.

At the start of the presentation three general premises will be offered: 1. All is process, 2. We are part of nature and 3. Three world experiments are currently underway. During this talk we may explore how these premises relate to the making and usage of materials in the development of humanity.

Electronic materials with a quest of high energy consumption are currently the basis for worldwide scientific, technological and cultural developments. Mathematical principles of symmetry, geometry and topology underlie the functionalities of the materials. At the nanoscale, materials design is governed by what I call the inverse Bauhaus-principle: “Function follows form”. Examples of topical research are given.

Finally, in view of global challenges (third premise) I will ask: How can we develop science further? A key component will be to promote a universal interdisciplinary dialogue.

Saskia F. Fischer is a German experimental physicist and professor at the Humboldt-Universitaet zu Berlin since 2010. She is leading the Novel Materials group and received the Helmholtz Prize for high-precision ‘Nanometrology’ with her team and partners in 2020. Saskia Fischer is known for her research work on novel electronic materials investigating how mathematical principles of symmetry, geometry and topology influence flow of charge, heat and spin. She frames the influence of geometry in material design at the nanoscale as the inverse Bauhaus principle: “Function follows form”. This allows to adapt material parameters such as thermal and thermo/-electrical conductivities for future applications in quantum, nano and power electronics. Beyond her specific discipline, her interests span from foundations of quantum physics to a development of universal interdisciplinary science in order to prepare for current and future global challenges.
