Condensed concepts

 In philosophical discussions of emergence and reductionism in chemistry, molecular structure has received significant attention and debate....

On the arXiv, I have posted a new version of my review article,  Emergence: from physics to biology, sociology, and computer science . I hav...

 In computational quantum chemistry, the Born-Oppenheimer approximation (BOA) is used to determine potential energy surfaces (PES) for elect...

In discussions of emergence, particularly in chemistry, isomers are often given as an example of an emergent phenomenon. In Anderson's o...

Electronic systems with large amounts of static disorder can exhibit distinct properties, including localisation of electronic states and su...

In the previous post, I considered five different characteristics that are often associated with emergence and classified them as being asso...

There is more to emergence than novel properties, i.e., where a whole system has a property that the individual components of the system do ...

Working in quantum many-body theory, I slowly learned that many key concepts and techniques have predecessors and analogues in classical sys...

The concept of emergence is central to understanding sub-fields of physics and how they are related, and not related, to other sub-fields. T...

 I am not sure I have seen this before. If you watched the movie Oppenheimer, you may have noticed that a one point a student excitedly show...

I was very sad to learn last week of the tragic death of Seth Olsen in an accident. He was a former collaborator and colleague at UQ. Seth...

To the uninitiated (and particularly physicists) computational quantum chemistry can just seem to be a bewildering zoo of multiple letter ac...

Seth Olsen kindly lent me his copy of Chemistry, Quantum Mechanics, and Reductionism  by Hans Primas, published in 1981. I has a Foreword b...
