The Joy of Condensed Matter - "Hard times in fundamental physics got you down? Let's talk excitons."
We are living in the golden age of condensed matter physics. But first, what is “fundamental” physics? It’s a tricky term. You might think any truly revolutionary development in physics counts as fundamental. But in fact physicists use this term in a more precise, narrowly delimited way. One of the goals of physics is to figure out some laws that, at least in principle, we could use to predict everything that can be predicted about the physical universe. The search for these laws is fundamental physics...also btw...
Unfortunately, progress on these questions has been very slow since the 1990s. Luckily fundamental physics is not all of physics, and today it is no longer the most exciting part of physics. There is still plenty of mind-blowing new physics being done. And a lot of it—though by no means all—is condensed matter physics.
- See World's First Video of a Space-Time Crystal - "In 2012, the Nobel Prize winner in physics Frank Wilczek discovered the symmetry of matter in time. He is considered the discoverer of these so-called time crystals, although as a theorist he predicted them only hypothetically. Since then, several scientists have searched for materials in which the phenomenon is observed."
- What is Reality? - "Nobel laureate Frank Wilczek investigates the ideas that form our understanding of the universe: time, space, matter, energy, complexity, and complementarity."
- Physicists Just Found 4 New Subatomic Particles That May Test The Laws of Nature - "The LHC has now discovered 59 new hadrons. These include the tetraquarks most recently discovered, but also new mesons and baryons. All these new particles contain heavy quarks such as 'charm' and 'bottom'. These hadrons are interesting to study. They tell us what nature considers acceptable as a bound combination of quarks, even if only for very short times."
- How to Rewrite the Laws of Physics in the Language of Impossibility - "Chiara Marletto is trying to build a master theory — a set of ideas so fundamental that all other theories would spring from it. Her first step: Invoke the impossible."
