"Imagine a cocktail party of political party workers who are uniformly distributed across the floor, all talking to their nearest neighbours. The ex-Prime Minister enters and crosses the room. All of the workers in her neighbourhood are strongly attracted to her and cluster round her..."
A perfect analogy given the intended recipient, I thought.
Last year I took a course about particle physics and we saw the equations of the standard model.
I like more the explanation that involves "pencils". I think that it is possible to expand the non-technical words and get something like the correct theory for Higgs bosons (for example: pencil->vector). In this explanation there are a lot of details missing of course, for example: Why the Z and W particles have different mass? How do the electrons get their mass? What is the difference between the waves that rotate the pencils and the waves that stretch the pencils? I think that these simplifications are sensible to get a short explanation.
I don’t like the explanation that uses viscous forces. The main problem is that with viscous forces the particles "lost" energy and the particles should become still. The real effect of the Higgs field is similar to the apparent effective mass of an object in a fluid. To accelerate the object it is necessary to accelerate some of the fluid that is around it, so it is more difficult and the object have a bigger apparent mass. This is unrelated to the viscosity and happens even when the fluid has no viscosity.
Another problem with this explanation is that the when the particles move they don’t drag any Higgs bosons (real or virtual). So the mental image is wrong. A possible way to see this is that as the vacuum expectation value of the Higgs field is not zero, the particles can "bounce" against the vacuum and the result is something in the movement equation that looks like a mass. It sounds strange or even ridiculous, but in the problem is not in the equations, but in the "translations" to non-technical words.
Interesting.
similar in some ways to the electromagnetic field [..]
That explanation just lost 90% of its audience, who have no clear conception of what an 'electromagnetic field' is. Physicists, including myself, can't help themselves in taking things for granted that their audience really doesn't understand.
Higgs proposed that ".. the whole of space is permeated by a field, similar in some ways to the electromagnetic field. As particles move through space they travel through this field, and if they interact with it they acquire what appears to be mass. This is similar to the action of viscous forces felt by particles moving through any thick liquid. the larger the interaction of the particles with the field, the more mass they appear to have. ..... We know from quantum theory that fields have particles associated with them, the particle for the electromagnetic field being the photon. So there must be a particle associated with the Higg's field, and this is the Higgs boson."
