Symmetry is one of the two guiding principles in understanding probabilities – if different outcomes are equivalent they should have the same probability.

How to get massive particles from gold.

After having explored our economic analogy for the force of electromagnetism, let us turn to the weak force.

Current physical theories suggest that beautiful symmetries underly the fundamental particles and forces of nature. We describe those symmetries using an analogy from economics, and even rediscover the famous Higgs boson.

Now let's look at the economic analogy for electromagnetism.

And finally, here is how the famous Higgs boson gets into the picture.

We all instinctively recognise symmetry when we see it, but describing it in words is harder than you might think.

We all know what symmetry is. But why does it play such a central role in modern physics?

A closer look at the power of symmetry in physics.

Celebrating the 150th anniversary of Maxwell's equations we talk to physicist John Ellis about what they mean for modern technology and our understanding of the Universe.
