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 lecture will begin with Bacon’s imagined garden, then consider the long-term promise of the experimental or scientific garden, which would eventually lead to today’s biotechnologies.
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.
We will need an aggressive strategy to ensure the safety of agricultural yields and food in the future especially in drought- prone and even temperate zones.
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.
