This one type of stuff, which means stuff that always has an interesting field around it, has lots of use in computers and such things. This field changes easily when you do something to the stuff, which means the stuff can be used to sense changes. The stuff will lower another field you put it in quite a lot, so the stuff is good for this if needed. Because the direction of the field can be changed with another field, the stuff can be used as memory.
For these things, the stuff is used in very small pieces. In these cases, the stuff acts a bit funny. The other stuff on which the stuff is grown will change the stuff, and this changes its field. This has not been used in computers and other things yet. Further, putting two slightly different pieces of this stuff together gives you edges, which can have completely new funny things happening in them. New strange things can be found at the edges between well-known pieces of stuff. Understanding how the fields work in this stuff and its edges is quite a new thing. These funny edges could also be used in making computers and such things. Trying to understand what other stuff will do to the field in the stuff, and what edges between pieces of the stuff will do, needs lots of big computers, because the new funny things come from small changes between different states of tiny things in the stuff, when other things are slightly changed. Figuring out how the stuff works is possible with this one way of doing it, which can give a pretty good idea of what happens when lots of tiny things are together.
In this book, I first tell about my ideas on well-known stuff when grown on top of other stuff. Together with people who check how the stuff works, I say that it is possible for some stuff to have a funny field it would usually not have, if it is grown on top of another stuff. Further, I find out that the direction and other things of the stuff under it will change the field that the stuff on top will have. In the (111) direction, different stuff under it can change the field that the stuff on top will have, or even stop the stuff from having a field.
Second, I talk about my studies on edges between two slightly different stuff. One type of edges are found to be interesting, which means they can have tiny things moving on them. The type of edge changes how tiny things move in the stuff. Further, together with people who check how the stuff works, I suggest that one type of edge will become very interesting, because it will also have another type of field. This is a field that is usually not in this stuff, because it happens at an edge where tiny things can move, between two pieces of stuff where tiny things can’t move and which do not have this type of field.
