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.
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?
Drones are changing the face of war in the 21st century for combatants and civilians. Today drones carry out targeted assassinations, bombings and intelligence-gathering, and the forces that deploy them aim to minimise the loss of life.
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.
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.
This talk will explain how to discern what and who to trust, how to know whether evidence is causation or just a correlation, and how to overcome the temptation to accept views that we agree with.
