Fortunately, a versatile strategy exists that allows you to take the lead in the dance: multiple equivalent simultaneous offers, or MESOs.

As in the double slit experiment, the simultaneous presence of two parts, a and b, seems to lead to some kind of weird interference that spoils classical probabilities.

Some combinations of simultaneous equations for obtaining lattice constants of low-symmetry crystal systems can lead to a serious accumulation of errors and the formation of abnormal state equations.
