Condensed concepts

In 1986, Steven Weinberg published an article,  Superconductivity for Particular Theorists , in which he stated "No one did more than N...

I just posted on the arXiv a long review article on emergence Emergence: from physics to biology, sociology, and computer science The abstra...

Novelty.  Temperature and entropy are emergent properties. Classically, they are defined by the zeroth and second laws of thermodynamics, re...

Einstein’s theory of General Relativity successfully describes gravity and large scales of length and mass. In contrast, quantum theory desc...

Superconductivity beautifully illustrates the characteristics of emergent properties. Novelty.  Distinct properties of the superconducting s...

Atomic nuclei are complex quantum many-body systems. Effective theories have helped provide a better understanding of them. The best-known a...

What is a fundamental theory? As we go to smaller and smaller distances and higher energies we keep finding new entities: atoms, electrons, ...

The figure above shows the stratification of objects that interest physicists. As one goes down the chain length and time scales get smaller...

 Over the last hundred years, there has been a fruitful cross-fertilisation of concepts and techniques between the theory of condensed matte...

What do we mean when we say something in science is fundamental? When is an entity or a theory more fundamental or less fundamental than som...

When I read Fundamentals by Frank Wilczek I learnt something that I found beautiful and amazing about general relativity and quantum field ...

What are the most amazing things that we know about the physics of the universe? If you were to pick ten what would they be? I recently read...

If you ever write a popular book about science I suggest you spend a lot of time honing your very last paragraph. If it is eloquent, grand, ...

Why are string theorists celebrities who write best-selling books and popular documentaries? Why are cosmology and particle physics seen as...
