Since the thermal conductivity of air at 1 atm and 300 K is about 0.026 W/mK, the rate of heat transfer by conduction across 1 m and a temperature difference of 1 K would be 0.026 W/m2.

I might add, with regard to the adiabatic demagnetization, I found a better way to get the data rather than having to push below 12 mK off the end of my dilution refrigerator.

This analysis showed that the total standard uncertainty of the temperature measurement process at Taylor Dome ranged 3.4 – 3.7 mK once the necessary bias corrections are applied.

For the borehole paleothermometry climate-reconstruction technique, perhaps a more relevant metric is the standard uncertainty of the relative temperature measurements which ranged 1.8 – 2.0 mK at Taylor Dome.

Beware that the sought for trend in the data is small, between 60 and 180 mK/decade, which is much smaller than the signal noise? caused by ENSO and volcanics.

There are four mechanisms dominating the temperature record: Volcanos, ENSO, Sun, and GHG, the first three can easily be derived by linear multivariate analysis the magnitue of last one is unknown, however if we also assume linearity as is the proven for the first three mechanisms a linear trend between 65 and 173 mK/decade is the result.

In 1985, the group reported cooling a dilute vapour of about 105 neutral sodium atoms in a volume of 0.2 cm3 to a temperature of about 0.2 mK.

In a gas of ideal two-level atoms one can easily calculate the limiting temperature, the so-called Doppler limit, which for the resonance transition in sodium would amount to 0.24 mK.

They were actually not looking for superfluidity, but for an antiferromagnetic phase in solid helium-3, which according to predictions was to appear below 2 mK.
