In this talk, Dr Wilkins will discuss the astrophysical origins of the chemical elements, almost all of which have an origin ranging from the big bang, to exploding white dwarfs, the collapse of massive stars, and the merger of ultra-compact objects, neutron stars.
This talk will review the dramatic consequences on what we observe in the night sky that arise purely from the consequences of light-travel time effects.
This talk will explain how to focus on important long-term goals but at the same time meet urgent short-term deadlines; how to use email as an effective communication tool without being overwhelmed with it; and how to outsource and automate routine tasks.
This talk will explain how the speed of light was first measured, and how an obscure but brilliant patent clerk in Bern, Switzerland by the name of Albert Einstein deduced that the speed of light is the upper speed limit for everything in the Universe.
This talk looks at mathematical modelling of real, complex fluids in flow situations – some with serious commercial applications, and some just for fun.
In this final lecture we will consider whether we can plot a more successful future than our recent history might suggest and what that implies for our economic and political institutions.
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.
