From Dan Thomas
I enjoyed your piece on clouds soaking up more sunlight that they ought to
(15 July, p 36).
If meteorologists were cosmologists they would even now be
speculating on a hitherto unknown exotic particle. Massless and unreactive, it
would be intrinsically undetectable except for absorbing surprisingly large
amounts of sunlight when present in clouds. No doubt they would give it a short
and snappy name, something like “damp grey matter” perhaps?
