A loaf of bread "knows" it is a loaf. After you cut it with a steel knife, you can't put the two halves back together and reform a whole loaf. How do the molecules on the edges "know" they are no longer a loaf?

The surfaces of the bread(or any solid) is not smooth enough. When you put it back together, only a few points on each side will touch each other.
It may seem like there is a close contact, but at molecule level, only a very small fraction will come close enough to make a new bond.
The bread will come back together, but the bond will be to weak to be noticed and when it falls apart again, you cannot see if a few molecules have moved from one side to the other.

The chemical reaction that created surface tension needs to re-occur for the bread to be brought back together. If you stuck the pieces back together with raw dough, and re-cooked that area, it would "weld" the two pieces together again. Why did you cut the piece, if you weren't going to eat it? Wasteful. Give it to the squirells, they'll not think about why it's square and if you can make it dough again if it "knew" how to be dough again. They just eat it and be thankful that they won't die from starvation that day.

You CAN join them back together. You just have to smush them a little. It's not pretty, but it's a loaf.

a loaf of bread knows nothing, it does not have brains for thinking. it does not scream in pain when you cut it.

First of all, stop taking drugs.
You physically change the bread by cutting it. If you care so much, glue it back together.
By the way, since you have some bread, could you make me a sandwich, I'm kinda hungry.

they never "knew" they were a loaf in the first place.
If the milky way split in two - would you know?

Because you cut them. If you use glue, the glue molecules will put the two halves together.

because you split the molecules. nd now they think there a new loaf.

Because you cut it it can't grow back together unlike dough because the The starch and in a solid state
