At some point, precision reaches a scientific limit. Due to [[quantum mechanics]], and especially the [[Heisenberg Uncertainty Principle]], at some point precision in measurement is impossible without the imparting of energy onto the measured object. For this reason, precision at the [[atom|atomic]] level is difficult to obtain. One example is, instead of referring to [[electron|electrons]] in a particular location around an atom, scientists determine what area of space they ''could'' occupy, and label this area a probability cloud, or an [[orbital]]. | At some point, precision reaches a scientific limit.
