There is
a finite number of molecules but a practically infinite number of infrared photons impinging continuously on them.
Not exact matches
As each sequencing glass slide can sequence only a
finite number of DNA
molecules, higher levels
of multiplexing would lead to fewer DNA
molecules to be sequenced per sample.
That case nonetheless remains relevant, because it illustrates by exaggeration something that remains true independently
of how large the
number of molecules gets: the mean molecular translational kinetic energy decreases with height, and it does so at a rate that is
finite and non-zero, albeit negligible for most purposes.
As I read it, it says there will be a lapse rate that's small for large
numbers of molecules but stll
finite and non-zero so long as the
number of molecules is not infinite.
