One of the key principles behind the two fundamental theories, that scientists discovered in the 20th century — the standard model of particle physics and the theory of general relativity — is locality. Local interactions, local degrees of freedom, local field theories. This is what I would like to discuss now. What is locality? Before…Read more LOCALITY AND ITS DISCONTENTS
In the following I would like to discuss this question: when we search for a fundamental theory, what relationship should there be between the quantum and the classical? Or put differently: which one is primary, the classical or the quantum? The operational arrows of quantum vs. classical Let me try to explain these questions by…Read more Quantum or classical: which is primary?
The noble art of gold digging I sometimes think of fundamental research in terms of the noble art of gold digging. When you dig for gold you need two basic skillsets. First of all, you need to be able to find the right place to dig. And secondly there is the digging itself. And those,…Read more YOUNG RESEARCHERS: GO ROGUE
In the following I will discuss what I consider the most fascinating and intriguing development in theoretical high-energy physics in the past some forty years, namely the research field known as noncommutative geometry. The core business of noncommutative geometry, which is pioneered by the french mathematician and field medalist Alain Connes, is is to produce…Read more Noncommutative Geometry and the Standard Model of Particle Physics
In the following I am going to discuss the theory, which I have developed with the mathematician Johannes Aastrup over the past some 15 years. This work is rather technical and involves several different fields in contemporary theoretical physics as well as new conceptual ideas rooted in modern mathematics. In this piece I am going…Read more A final theory from empty space
— what are we looking for? One of the main reasons for me to write this blog is that I would like to write about my work with the mathematician Johannes Aastrup. Over the past some 15 years we have developed a candidate for a fundamental theory, a final theory. But before I write about…Read more The search for a final theory
I have made a video, where I discuss my work with Johannes Aastrup. This video is primarily intended for a broad audience - everyone! - but its also a "thank you!" to all those who backed my crowdfunding campaign in 2016. I hope that you with this video will get a better idea about where…Read more My work with Johannes Aastrup
