This talk looks at mathematical modelling of real, complex fluids in flow situations – some with serious commercial applications, and some just for fun.
Matter consists of a mêlée of elementary particles. There are protons and neutrons, made up of quarks, and many other short-lived massive particles. One hope is to discover particles of dark matter, but this has so far eluded our best efforts.

A celebration of the heart for St Valentine’s Day. How is it that a simple pump has become a symbol of the highest human emotions of love, truth, conscience and moral courage? How have artists represented this? An interdisciplinary presentation.
Can a scientific theory ever be confirmed? Must a scientific theory be falsifiable? Theories such as that of the multiverse and string theory will be considered.
Sudden death in the young is more common than you think... This lecture considers the causes of sudden death, its impact on families, the difficulties of carrying out research, and some of the legal and social obstacles to discovering more.
