Experimentation in the temperature range 1 to 4°K in liquid helium requires very little skill or sophistication. An experimentalist of very modest dexterity can learn to conduct experiments in liquid helium in a very short time. Considering the ease of this first step into this temperature range, it is only natural that the experimentalist is appalled at the great difficulty of the next step, that of applying continuous reliable refrigeration for the same temperatures. The complexity and cost of even the simplest systems are surprisingly large.
