Each year the Symposium highlights the fast evolving and diverse nature of soft matter science and related areas of statistical physics. These fields relate to many industrial and biological systems and can involve a wide range of disciplines. The science area has led to many materials and processes for industry and commerce while also posing new fundamental problems. The Symposium continues to build on Sir Sam’s realization that broad classes of system are governed by unifying physical principles, arising from the geometry, topology or other qualitative behaviour of their underlying constituents.
