The Incomplete Knowledge Of A System Must Be An Essential Part Of Every Formulation In Quantum Theory. Quantum Theoretical Laws Must Be Of A Statistical Kind. To Give An Example: We Know That The Radium Atom Emits Alpha-radiation. Quantum Theory Can Give Us An Indication Of The Probability That The Alpha-particle Will Leave The Nucleus In Unit Time, But It Cannot Predict At What Precise Point In Time The Emission Will Occur, For This Is Uncertain In Principle.
