When black holes merge, the world shakes. Such quakes in space-time are now detectable and indeed the detection of such gravitational waves from cosmic coalescences comprises an entirely new type of astronomy that is completely independent of light itself.
Could AI replace stand-up comedians and scriptwriters? This may not be an impossible dream if you accept that nothing we do is forever beyond the scope of computer modelling.
This talk relates true stories of life-changing events in which the use (or abuse) of mathematics has played a critical role. You will meet innocent victims of miscarriages of justice and the unwitting victims of mathematical bugs.
Where do we get our mathematical symbols from? Why is the set of integers called ℤ ? When was the equals sign first used? How about zero? Good notation tends to catch on quickly, whereas bad notation can obscure beautiful theory.
Space today is terrifyingly silent. But it wasn’t always thus: the early universe was filled with a hot plasma in which sound waves could travel. The cosmos was quivering with the aftershocks of the Big Bang.
Even the most humdrum of electrical devices nowadays contains at least one computer; yet surprisingly few people are aware of their history, their form or function. In this talk we will see that not only is the history of computers rich and diverse, their architecture likewise.
Highly energetic particles from outer space travelling at the speed of light, known as cosmic rays, originate from the sites of extreme particle acceleration in the Universe.
