To Computer Modellers mince pies are actually seasonal examples of heterogeneous systems: pastry (a blend of composites and water) + mincemeat (mixture of differently shaped and sized objects). We are offering the opportunity to talk more about this, sample some mince pies and learn more about HetSys and our available projects for 2023 entry on Thurday 8 December between 12 noon and 1.00pm. We look forward to seeing you there!
