Condensed concepts

Yin-Zhe Ma gave a nice physics colloquium at UQ last week, A Golden Age for Cosmology I learnt a lot. Too often, colloquia are too speciali...

Two characteristics of states of matter are associated with them being referred to as quantum. One characteristic is the importance of quant...

Attempts to develop a quantum theory of gravity continue to falter and stagnate. Given this, it is worth considering approaches that start w...

Time has a direction. Microscopic equations of motion in classical and quantum mechanics have time-reversible symmetry. But this symmetry is...

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...

Nuclear physics exhibits many characteristics associated with emergent phenomena. These include a hierarchy of scales, effective interaction...

In 2016, when I saw the first results from the LIGO gravitational wave interferometer my natural caution and skepticism kicked in. They had ...

This is ultra-condensed matter physics! In 1931,  Subrahmanyan Chandrasekhar published a seminal paper, for which he was awarded the Nobel ...

 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...

Since we are surrounded by scientific knowledge. We are so used to it that we can take science for granted and not reflect on how amazing sc...

The comet C/2022 E3 (ZTF) getting a lot of attention , pointed out to me by my friend Alexey. Why is it green? This basic question turns out...

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, ...

There are several independent lines of argument that are used to support the idea of a multiverse: the many-worlds interpretation of quantum...

I learnt today that David Pines died last week. He was a pioneer in quantum many-body theory, applying it not just to solid state physics bu...
