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.
Niklaus Wirth said Algorithms + Data Structures = Programs. But programs are more than that. They are ubiquitous in modern life, but only a tiny minority of the population know how to program.
Humans use computers to do gigantic calculations which would be impossible to do by hand – for example, weather prediction. But could an AI go beyond that and come up with a proof of a theorem which has stumped humankind?
Data structures are the critical ingredient of all good information systems. Poor data structures lead to horrendous problems of interoperability and nightmarish complexity; good ones can make the ‘uncomputable’ computable.
Over the last 30 years, digital technology produced an exponential increase in astronomical data. Within our lifetime, the entirety of the visible universe will have been mapped out: we will have seen everything there is to see. The question will then be: what does it all mean?
The 2020 Alfred Wiener Holocaust Memorial Lecture Series - 2020 marks the 75th anniversary of the liberation of Auschwitz, the most lethal of all Nazi camps.
London in the 1950s and 60s was a crucible in which West Indian writers, artists, thinkers and scholars imagined new futures for the Caribbean, Britain and the world.
This lecture examines the centuries long presence of the African diaspora as an integral part of Britain’s history since Roman times. Unfortunately, this history is still too often ignored, its promotion limited only to October.
Algorithms, loosely translated, are systems for doing things. Algorithms are thus the link from pre-history to the modern world – without algorithms we would have an inanimate universe without all the mess and complexity of real life. It turns out that the history of algorithms is messy.
Traditionally a lawyer’s own views and political affiliation are irrelevant to the pursuit of the legal process. This lecture will examine – and celebrate – the work of lawyers who have crossed the usual lines and worked for political change.
