Adding an image of quasicrystals might be more informative?

An example of the electron diffraction pattern of a quasicrystal

We could use an image of the diffraction of a quasicrystal in the "Aperiodic materials" sub-sub-section. This would really show the "aperiodicity" of the diffraction patterns of such materials. Currently, I am looking at figure 15 and I cannot understand why it is aperiodic from the first glance. However, the diffraction patter of a quasicrystal is obviously aperiodic.

i am OK with replacing the current Figure 15 -- it's not mine, but she won't mind. The text would need to be changed with a high-schools explanation of how it is aperiodic in a few sentences. Do you want to take a stab at it in the talk? Ldm1954 (talk) 01:36, 17 August 2023 (UTC)[reply]

All right, I will give it a try...

An extreme example of aperiodic materials is for quasicrystals. Atoms in quasicrystals are ordered, but they do not have a repeating pattern^[1] and has no translational symmetry.^[2] An example is given in Figure 15...

I am not very sure how to introduce the image through the text, and I don't know enough sources to properly introduce quasicrystals. @Ldm1954: please go for it. I trust in your expertise. TheLonelyPather (talk) 13:07, 17 August 2023 (UTC)[reply]
