In geometry, sphere packing refers to the arrangement of nonoverlapping spheres within a containing space. An everyday example would be how oranges may be stacked as closely and thus efficiently as possible. What appears to be a rather ordinary task, has stumped mathematicians for centuries. It was only in 1998 that it had been proven that the best solution for packing spheres in a threedimensional space was in the shape of a pyramid. In 2022, Maryna Viazovska received the prestigious Fields Medal, often described as the Nobel Prize of Mathematics, for solving the spherepacking problem in 8 and 24 dimensions. Viazovska, who holds the Chair of Number Theory at École Polytechnique Fédérale de Lausanne, proved that the E8 lattice provides the densest packing of identical spheres in eight dimensions. At Falling Walls, Viazovska discusses how she solved the longstanding problem in a particularly elegant way. She also provides a sense of what it was like to conduct her research in the context of the war in Ukraine.

About the Falling Walls Science Summit

Three days of intense scientific discussions, networking, and knowledge sharing in the incredible cosmopolitan city of Berlin!

The Falling Walls Science Summit is a leading international, interdisciplinary and intersectoral forum for scientific breakthroughs and science dialogue between global science leaders and society. The event takes place every year from 7–9 November in Berlin, commemorating the fall of the Berlin Wall. With formats Falling Walls Pitches (7 November), Falling Walls Circle (8 November) and Falling Walls Science Breakthroughs of the Year (9 November), the Falling Walls Science Summit is the leading forum for global science leaders from academia, business, politics, the media, and civil society to debate the potential of scientific breakthroughs to solve grand challenges and shape a sustainable future. The Falling Walls Science Summit is organised by the nonprofit Falling Walls Foundation.
