1001 things to do with liquid nitrogen

1001 things to do with liquid nitrogen: "In the course of studying physics one is officially taught that liquid nitrogen is simply (and mainly) used to cool things down to 77K. But everybody who once has observed students in practical courses 'working' with this stuff knows that this is not true.
My intention is now to tell the truth about what is really done with liquid N2 before its remains are taken and used for cooling. "
