the same laboratory, opened up, along with workers in Cam- 

 bridge, Massachusetts, and Oxford, England, the new subject 

 of microwave spectroscopy. From the host of contributors in 

 that field, especially from the keen combiners of theory and 

 experiment, have come such advances as Purcell's findings of 

 the 2 1 -cm wavelength emission from clouds of hydrogen gas 

 in outer space. Now, of course, everyone knows what to do in 

 radioastronomy, to judge by the grants made for it and the 

 worldwide attention it is receiving. 



Finally, How Will the Scientist 

 Treat This Paradox? 



We have proposed that the cultivation of unifying physical 

 theory and ultimately of biological theory and social science
