I tried to pace myself going through this one, so that all of the photos would not blur together.
That was a reasonable precaution, but I was amazed at how much the opening text helped. It was only a few pages long, and as it starts with some information about the science and methodology, that is information that is useful but kind of boring. Then it did two things.
First it talked about how the symmetry is not perfect, and then you start seeing how some ends did not get as long, or there were cracks in the middle, or something. It is completely logical, but it would be something that is easy to miss when there is often so much intricate symmetry.
Then it talks about our tendency to see shapes in things (like when we look at clouds), and mentions some shapes on specific pages, getting almost whimsical. Then you start seeing them too. Yes, there are a lot of pilot wheels, perhaps, but then some look like they have writing around them, but you can't read the writing, and the shapes become even more fascinating.
Bentley's achievement in photographing snow crystals would be significant on its own, as would the photos, but the arrangement makes appreciating all of that easier.
