After the UN Climate Action Summit in September, our Environment Professor will be talking to three experts about whether we still have a meaningful chance of averting a climate catastrophe, and how we can get there.
This talk looks at mathematical modelling of real, complex fluids in flow situations – some with serious commercial applications, and some just for fun.
Climate change is important, controversial, and the subject of huge debate. Much of our understanding of the future climate comes from the use of complex climate models based on mathematical and physical ideas.
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.
What happens when power, communications, and transport are all disrupted, when shops cannot function, and when most people cannot find out what is happening? Storm Desmond in 2015 revealed how dependent on electricity modern city life has become. What lessons have been learnt?
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.
In the first three minutes after the beginning of the universe, all of the stuff that we and the Earth are made of were created and the universe attained its huge size, homogeneity and isotropy.
Human-induced climate change is the greatest threat encountered by humanity. What is the latest evidence about what is happening to the global climate? What environment might our children face in 2100? What strategies might we use to make a difference?
