Formal languages inevitably are less human readable than natural languages. However, some formal languages are less human readable than other formal languages. These are low-level languages. Being simple they are convenient for theoretical analysis and automatic processing. Being poor they are inconvenient for expressing human thoughts. To this end one needs high level languages, rich of means of expression. (This situation is observed in logic and programming as well.)

The Heisenberg uncertainty principle for a particle does not allow a state in which the particle is simultaneously at a definite location and has also a definite momentum. Instead the particle has a range of momentum and spread in location attributable to quantum fluctuations.

An uncertainty principle applies to most of quantum mechanical operators that do not commute (specifically, to every pair of operators whose commutator is a non-zero scalar operator).
