Secrets and lies: The hidden power of maths
Mathematician Dr Hannah Fry presents the 2019 CHRISTMAS LECTURES
We think our lives unfold thanks to a mix of luck and our own personal choices. But that’s not quite true. An unseen layer of mathematics governs every aspect of our world.
Life’s most astonishing miracles can be understood with probability. Big data dictates many of the hot new fashions we follow. Even our choices on Netflix, or our choice of who we marry, is secretly influenced by computer algorithms.
In a series of lectures packed with mind-boggling demos and live experiments, Hannah shows us how to decode life’s hidden numbers; to help us all make better choices, sort fact from fiction, and lead happier lives. But she also warns how our unwavering faith in figures can lead to disaster when we get the sums wrong.
Unravelling suspicious statistics, engineering meltdowns and deadly data, Hannah asks big ethical questions about the trust we place in maths today. Are there any problems maths can’t or shouldn’t solve? Do computer algorithms have too much control over our lives and privacy? Could A.I. decide if someone lives or dies?
Ultimately, by probing the limits of maths and its role in our modern world, Hannah ends up revealing and celebrating what makes our human minds so unique.
Lecture 1 – How to get lucky
In Lecture one, Hannah seeks to find the luckiest member of the audience. It seems a sensible plan. The biggest events in your life – finding the perfect partner or a job, staying healthy and happy – rely on a huge element of luck. Or does probability allow us to understand and predict complex systems?
Lecture 2 – How to bend the rules
In Lecture two, we see how ‘chaining probabilities together’ help us to understand even more complex systems. Through entertaining examples, Hannah shows how data-gobbling algorithms have taken over our lives and now control almost everything we do without us even realising.
Lecture 3 – How can we all win?
In Lecture three, Hannah looks at why maths can fail and asks what the limits of maths are. Are there problems maths can’t or shouldn’t solve? And in an age where ‘fake news’ abounds and statistics can be twisted to prove anything, should we always trust in numbers?
