There is the problem of the conciliation between relativity theory and quantum theory. Many different proposals, for example:

Quantum considerations are of importance for three reasons:
  • Heisenberg's uncertainty law: a reciprocity law
    For example: position versus impetus.
  • Quantum numbers: here, the natural numbers appear in the opposite way as expected!

  • Any measurement changes what has been measured.
