American and Dutch physicists reach new low temperature
The greatest cold produced and measured by man has now been pushed to within a quarter of a degree of absolute zero, that unattainable heatless point where all motion of the molecules cease and where gas would exert no pressure whatever.
Two groups of research workers, one at the University of California and the other in Holland, using novel methods identical in principle, have arrived at the extraordinary low temperatures of 0.25 degrees absolute and “certainly below 0.27 degrees absolute,” respectively.
