The quantum theory paper explained that the Stark effect, namely the splitting of the spectral lines of hydrogen by an electric field (the amount being proportional to the field strength), could be proved from the postulates of quantum theory.
Ang quantum theory papel ipinaliwanag na ang mga payak na effect, namely ang malakas ng multo linya ng haydrodyen sa pamamagitan ng isang electric field (ang halaga na nauukol sa larangan ng lakas), ay maaaring proved mula sa mga postulates ng quantum theory.
