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?
Psychological studies show that humans overweight tangible factors and underweight intangible ones when making decisions. This talk shows how these biases affect the stock market – it focuses excessively on short-term profit, but ignores environmental, social and governance (ESG) factors.
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.
The COVID-19 pandemic has been devastating. But one silver lining has been the tremendous responses from businesses and individual citizens, as we’ve realised how even small actions can have a substantial effect on society.
What are the opportunities for using Information Technology to reduce the cost of healthcare? And what might our healthcare system look like in 10 years time if we make judicious investments in technology?
This talk will explore the “growth mindset”, the evidence-based view that talents are developed rather than genetic. It provides practical tips on how to develop new skills with limited time, and highlights the importance of pushing yourself outside your comfort zone.
