Where did we come from? This question has always intrigued human thought. Professor Silk will describe the modern scientist's view of the origin of the cosmos.
Control measures including vaccination have reduced the risk of some, but not all, of these very serious infections. This lecture will cover how infections get into the brain, their effect and how we can prevent and treat them.
Professor Silk will describe the state of our knowledge of neutron stars and black holes, and how new observations of gravity waves are poised to revolutionise this field.
Professor Tallis seeks to rescue time from the jaws of physics, examining the claims that time is merely the fourth dimension of space-time, that there is a ‘passage’ of time or that time has a direction or arrow.
Asteroid impact could devastate the Earth, although preventive measures might detect and monitor orbits of potential killer asteroids. Longer term, the sun will evolve into a red giant and expand to a hundred times the orbit of the earth.
What are the implications of the Big Bang for our understanding of ourselves? Is the universe meaningless? or is there some way of developing a ‘big picture’ of reality that helps us decide our place and purpose in the universe.
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.
View the sky through an x-ray telescope and the conception of the universe changes dramatically. Black holes are best seen in x-rays, because impinging gas collides with the black hole at near light speed, resulting in intense x-ray and gamma ray emission.
