Gresham College provides outstanding educational talks and videos for the public free of charge. There are over 2,500 videos available on our website. Your support will help us to encourage people's love of learning for many years to come.
In this talk Dr Sheila Kanani combines the story of a pioneering woman astronomer, with an account of the science behind comets, asteroids and meteors.
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.
The nature of investment is changing to better reflect the ecosystem of the planet we live on. The days of fossil fuel are numbered by the move to renewable energy. Resources and a healthy environment are finally being seen as core to our future.
CEOs make mistakes due to their own psychological biases – but they also profit from the biases of others. Some exploit investors by catering to sentiment – adding “.com” to their name during the Internet bubble or entering “hot” industries to inflate their valuations.
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.
Gresham’s Professor of Law Jo Delahunty will explore what the future holds for the next generation of barristers: will they better reflect the society they serve in terms of background, ethnicity and gender? Is privilege and income as much of a division at The Bar as it is in society?
We often think that leaders are particularly strong in decision making – that’s why they’ve made it to the top. But evidence shows that even senior executives are prone to psychological biases, such as overconfidence, groupthink, and applying one-size-fits-all rules.
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.
When light is dispersed into its constituent colours, it can become possible to discern rich dynamical information about an evolving system in space, for example cosmic explosions, collisions or accelerations.
