Why, my good friend Novum, what this image shows is merely that "whatever is really out there" in that chunk of the real world (that has been placed under the electron microscope) happens to behave in the following way: it emits lights in particle like "clusters" that are themselves arranged in a geometrical lattice. It could be a bunch of tiny goblins, each holding a little light.Novum said:Stop the presses! Hold the phones! Pull the emergency brake on the train!
Drew, what are these things?
Hint: "Ti" means Titanium, "Sr" means Strontium.
Flippancy aside, this photo is not evidence that there really are "little atoms with clouds of electrons whirring about". The content of the photo is really just a pattern of light - presumably resulting from illuminating the item with electrons. This is all we really know from this photo - we think that this photo supports the "reality" of atoms only because we have previously constructed the atomic model and brought that interpretive framework to the viewing of the photo. So when we see this picture, we naively conclude that "atoms are real".
Let's say I fire a series of golf balls at some unknown structure in a darkened room. Let's say the golf balls come right back at us. This behaviour is entirely consistent with each of the following hypotheses about what is "really out there":
1. The thing out there = a flat surface
2. The thing out there = a "U" shaped tube open at both ends - the golf ball enters the tube at one end and zips around the tube and comes right back at us.
3. The thing out there = a little goblin that always throws things back in the same direction from which they come.
Now we may use principles of simplicity to rule out number 3, but who is to say that the "goblin" model does not make the results of other experiments easier to explain.
The photos simply show how the underlying reality is expressed on a piece of photographic paper. Any further conclusions are based on a model of reality that is brought to the viewing of the photos.
