CONCEBNING THE FIGUBE AND THE 



DIMENSIONS OF THE VNIVEBSE 



OF SPACED 



There is something a little incongruous 

 in attempting to consider the subject of 

 this address in a theater or lecture hall 

 whose roof and walls shut out from view 

 the wide expanses of the world and the 

 azure deeps. For how can we, amid the 

 familiar finite scenes of a closed and 

 blinded room, command a fitting mood for 

 contemplating the infinite scenes without 

 and beyond? A subject that has sheer 

 vastness for its central or major theme de- 

 mands for its appropriate contemplation 

 the still expanse of some vast and open 

 solitude, such as the peak of a lone and 

 lofty mountain would afford, where the 

 gaze meets no wall save the far horizon and 

 no roof but the starry sky. Perhaps you 

 will be good enough for the time to trans- 

 port yourselves, in imagination, into the 

 stillness of such a solitude, so that in the 

 musing spirit of the place the questions to 

 be propounded for consideration here may 

 arise naturally and give us a due sense of 

 their significance and impressiveness. 

 What are the dimensions and what is the 

 figure of our universe of space? How big 

 is it and what is its shape? What is the 

 figure of it and what is its size? 



I do not mind owning that these ques- 

 tions have haunted me a good deal from 

 the days of my youth. It happened in 



^ An address delivered under the auspices of tlie 

 local chapters of the Society of Sigma Xi at the 

 state universities of Minnesota, Nebraska and 

 Iowa, April 24, 28 and 30, respectively, and at a 

 joint meeting of the chapters of Sigma Xi and 

 Phi Beta Kappa of Columbia University, May 8.
