Physics Today is privileged to present an excerpt from a newly published essay by Albert Einstein. The excerpt is reprinted here from “Albert Einstein: Philosopher‐Scientist,” Volume VII of the Library of Living Philosophers,* with the kind permission of Paul Arthur Schilpp, editor of the series. The above title is the last phrase of the autobiographical introduction to the volume and the excerpt that follows is from the final essay “Remarks Concerning the Essays Brought Together in this Co‐operative Volume.” Professor Schilpp translated this material from the German typescript.

Thus another probe into space is available for examining bodies which are capable of emitting, reflecting, or absorbing radio waves.
