I am glad to have this opportunity of expressing my high appreciation of the honour extended to me many years ago by the Royal Swedish Academy of Science by enrolling me amongst its members.

Thanks to the high standing which science has for so long attain and to the impartiality of the Nobel Prize Committee, the Nobel Prize for Physics is rightly considered everywhere as the highest reward within the reach of workers in Natural Philosophy.

Every day sees humanity more victorious in the struggle with space and time.
