Moreover, the abundance of chemical compounds and their importance in daily life hindered the chemist from investigating the question, in what does the individuality of the atoms of different elements consist.

Thus at the beginning of 1906 it seemed to be established that the emitters of the spectral series of chemical elements are their positive atomic ions.

The most important truths are those which sustain us in our daily lives.

For under certain conditions the chemical atoms emit light waves of a specific length or oscillation frequency - their familiar characteristic spectra - and these can come in the form of electromagnetic waves only from accelerated electric quanta.

Sure, I acted in films in the Third Reich, entertainment films, which distracted countless people inside and outside Germany from daily life during war.

Sometimes we get so busy with our daily lives we do not take the steps and time necessary to be introspective.
