The Future of Computer Security

It is now easier to breach the security of people’s personal and business lives than perhaps at any time in recent human history. Technology has brought unimaginable speed, scale and reach to hackers.

Artificial Intelligence and Humour

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.

Networks: The Internet and Beyond

Networks were seen as a rather arcane and dull area in computer science. Then along came the internet, and everything changed for ever.

Cyber War Crimes

Cyberwar is not waged on physical battlefields following rules of engagement. Aggressors worry less about collateral damage, in part because they aren’t forced to confront the sight of an enemy bleeding to death before their eyes.

Computers: A History

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.

An Introduction to Programs

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.

Will Computers Outsmart Mathematicians?

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: The Past, the Present and the Future

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.

Understanding the Universe with AI

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?

An Introduction to Algorithms

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.
