A video tour of the Standard Model (2021)
The Standard Model of particle physics successfully predicts experimental outcomes but fails to explain gravity and dark matter. Efforts continue to develop a more comprehensive theory integrating mathematics and quantum field theory.

The Standard Model of particle physics is recognized as the most successful scientific theory, having accurately predicted the outcomes of numerous experiments. In a video by Cambridge physicist David Tong, the model is explained in detail, illustrating how fundamental particles and forces are interconnected through a comprehensive equation. Despite its effectiveness in explaining phenomena within our universe, the Standard Model has limitations; it does not account for gravity at short distances or the existence of dark matter and dark energy. This has led physicists to seek a more comprehensive theory that extends beyond the Standard Model. The relationship between mathematics and quantum field theory (QFT) is crucial in this pursuit, as mathematicians are encouraged to develop new perspectives to address unresolved questions in physics. The integration of QFT into mathematics is ongoing and may take considerable time, but it holds promise for advancing our understanding of the universe.
- The Standard Model is the most successful scientific theory, accurately predicting experimental results.
- It describes the interactions of fundamental particles and forces through a unified equation.
- Limitations of the Standard Model include its inability to explain gravity at short distances and dark matter.
- There is a push for a more comprehensive theory that goes beyond the Standard Model.
- The collaboration between mathematics and quantum field theory is essential for resolving major open questions in physics.

Can manim work with sympy expressions?
A standard model demo video could vary each (or a few) highlighted variables and visualize the [geometric,] impact/sensitivity of each
It’s like trying to teach someone AI/ML and only ever showing them vendor logos as illustrations and never the code or even pictorial representations of the models.
It’s absurd, yet 99% of such presentations for physics look like this — unnecessarily — because it is possible to show a rendering of fields, their various properties changing over time and space, etc…
You can’t learn anything from a thousand such videos that already exist, so what’s the point of a thousand and one? It adds nothing.
PS: To gauge if the content is meaningful or valueless, just ask yourself if anything would change about its educational value if you arbitrarily but consistently replaced the icons and/or their labels. If you’re still exactly as mystified as before, then their information content was zero. “The three quarks, rock, paper, and scissors have a three-way symmetry, blah blah blah”. Congratulations, you now know the quantum theory of roshambo!
