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.
Professor Wilks will describe the Semantic Web and its origin in annotation methods from the humanities and will argue the need for this form of AI to manage a lifetime’s information on the web.
Professor Wilks will discuss the notion of an artificial Companion, a long-term software agent that could be present in any device: a screen, handbag or even a furry toy - and which understands the person it 'lives' with.
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.
Alan Turing famously proposed a test of artificial intelligence. What has been achieved? Stephen Hawking has said that real artificial intelligence will mean the end of mankind. Is that a real threat? Are there limits to what a silicon brain might do?
In the long run, in an Internet society, it is claimed, we will neither need nor want doctors, teachers, accountants, architects, the clergy, consultants, lawyers, and many others, to work as they did in the 20th century. - Is this true?
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.
