# Recovered bore casing found to have kept a record of its own temperature

> A paper from the School of Underlying Conditions treats thirty-one years below the water table as an annealing experiment that nobody set up.

The School of Underlying Conditions has for some time taken the view that the ground is the most patient piece of equipment available to it. That view now has a paper attached. _Thirty-One Years at Seventeen Degrees: Secondary Crystallisation in Polyethylene Bore Casing Recovered from a Decommissioned Monitoring Field_ is the work of Dr Vigdis Emenike, Senior Lecturer, and Dr Brynjar Obiora, Senior Research Fellow.

> The ground kept its side of the arrangement for thirty-one years without once being reminded. The School means to be as dependable a party over the next ten, and there is a water bath in the building that commits us to it.

The paper brings 114 rings of recovered pipe into alignment with a laboratory series built to stand in for them, and positions the casing's long residence below the water table as a held temperature the plastic went on registering. The two accounts agree on a good deal and part by 2.1 kelvin, a difference the authors pursue through the pipe yard and the cooling tank and leave, in part, where they found it.

The University counts the paper among the returns on infrastructure it did not have to commission. Dr Obiora described the casing as "material that was in no hurry, studied by people who were asked to match it."
