Atomic memory
Atomic memory is a pseudo scientific concept needed for assimilation of matter arguments for singular theories of conscious existence. Science has not found any evidence of this property existing. If something like this actually exists it will exist for a short amount of time, with relatively little memory capacity, and be a physical property. It would have to be a memory of a previous or last chemical reaction. There would have to be some physical different between this atom and another atom with the same physical properties.
The concept of atomic memory, is basically, besides it normal scientific physical properties, is that atoms or molecules have a way of knowing what they belong to or have belonged to in the past, a memory of this past connection.
Most theorists, that are using this concept in their arguments do not even know that they are using a psuedo scientific concept in their reasoning.
