Israeli mathematician Saharon Shelah is one of the top experts on infinity and how it can be understood and distinguished mathematically. (Image: Wikipedia / ETH Zurich) - The fact that there are many different types of infinities is one of the big puzzles in mathematics. One mathematician who enjoys investigating which infinities can actually occur is Saharon Shelah, the guest speaker at this year's Paul Bernays Lectures. One of the most astonishing findings in mathematics is the discovery that there are many different types of infinities - and for a long time, it was an unresolved problem whether some of these infinities could be of different sizes without contradiction. One mathematical logician who has been studying this intensively for years is Saharon Shelah from the Hebrew University of Jerusalem. As the guest speaker at this year's Paul Bernays Lectures , he will discuss the current developments in "Struggling with the size of infinity". Shelah is an established expert on the topic of mathematical infinity.
