real world conditions

What do you mean by real world conditions? I believe that on Earth (in the outdoors) the lowest temperatures are around −50 to −60 °C. However in the laboratory people routinely measure at nanokelvin temperatures (10−9 K), which is very close to the absolute zero.--Paul Wormer 09:51, 14 December 2009 (UTC)
