The Standard Model of particle physics is the most successful scientific theory of all time. It describes how everything in the universe is made of 12 different types of matter particles, interacting with 3 forces, all bound together by a rather special particle called the Higgs boson. It’s the pinnacle of 400 years of science, and gives the correct answer to hundreds of thousands of experiments. In this explainer, Cambridge physicist David Tong creates the model, piece by piece, to provide some intuition for how all of the parts fit together to create the fundamental building blocks of our universe. At the end of the video, he also points out what’s missing from the model, and what work is left to do in order to complete the Theory of Everything.
Quantum computers aren’t the next generation of supercomputers—they’re something else entirely. Before we can even begin to talk about their potential applications, we need to understand the fundamental physics that drives the theory of quantum computing. (Featuring Scott Aaronson, John Preskill, and Dorit Aharonov.) For more, read “Why Quantum Computers Are So Hard to Explain”: https://www.quantamagazine.org/why-is…
“Declaring something impossible leads to more things being possible,” writes the physicist Chiara Marletto. “Bizarre as it may seem, it is commonplace in quantum physics.”
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.
Constructor Theory is a new approach to formulating fundamental laws in physics. Instead of describing the world in terms of trajectories, initial conditions and dynamical laws, in constructor theory laws are about which physical transformations are possible and which are impossible, and why. This powerful switch has the potential to bring all sorts of interesting fields, currently regarded as inherently approximative, into fundamental physics. These include the theories of information, knowledge, thermodynamics, and life.

The mangroves of Sri Lanka are home to a very special resident. The archerfish might not look that powerful, but it can fire watery arrows to take down its prey from up to two meters away. In this video, we’ll show you the archerfish’s unique hunting strategy, which also involves an astonishing grasp of physics and math. Behind those dual-action eyes, complex calculations are going on…
