The Art of Thinking Clearly

What is understanding? How can we understand things better? How do we use models, analogies and metaphors to understand better the world around us? Speaker Roger Antonsen designed this keynote to give you the answers to these questions.

• Understanding is something everyone possess. There is always a reality behind abstract concepts and descriptions. This keynote will explore this reality – the territory behind the map.
• Good mental and scientific models are essential for us to understand things. However, as this talk will discuss, we often become dependent on them – preventing us from real understanding.
• Roger is can also tie the keynote both to programming and mathematics: What is mathematical understanding? What is the connection between mathematics and metaphors? How to capture the essence of mathematics?

The Algorithms in our Lives

Today, algorithms and programming is everywhere, but what is really an algorithm? What does coding, data, programming and computer science mean? What kind of programming languages are there?

• This entertaining and easy-to-understand keynote will give you an introduction to the key concepts related to programming and algorithms – using visual demonstrations and many other examples.
• In this presentation, speaker Roger Antonsen can also talk about the history of computer science. From Leibniz to artificial intelligence and cryptocurrencies, Roger is ready to provide you with a historical overview of computer science and programming.
• It is also possible to link this talk to logic and mathematics: How to use programming in teaching mathematics? How can programming contribute to critical thinking and mathematics?

The Magical Patterns of Mathematics

Roger offers this entertaining and colorful talk to show you the most exciting aspects of mathematics and the most colorful and creative sides of computer science. In this talk, speaker Roger Antonsen unveils how to experiment with mathematics and how creative programming can really be.

• “Magical Patterns” has been designed to evoke curiosity and show the beauty of mathematics. This keynote is not about formulas and calculations – it will rather show you the colorful and different world of mathematics. Roger will talk about hexaflexagons, origami and juggling and more abstract concepts such as multiple infinites and fixed points.
• Roger is available to talk about many different topics: How many ways to tie a tie knot? What is the connection between mathematics and juggling? How many moves are required to solve Rubik’s cube?
