Measurements of quantized magnetic flux establish that pairing is empi
rically present in all known superconductors, whether the old low-temp
erature elemental ones or the newer high-temperature cuprates. The pai
ring phenomenon is explained and derived, analytically and graphically
, in a simple one-dimensional model with an attractive 6-potential. Th
e model displays a smooth continuous evolution from the loosely-bound,
strongly-overlapping Cooper pair extreme reminiscent of low-temperatu
re, to the well-separated, tightly-bound composite bosons extreme more
characteristic of high-temperature superconductivity. This latter pro
perty makes it useful in addressing exotic superconductivity where str
ong suggestions of a link with Bose condensation emerge from recent ex
periments. The interaction model does not exhibit all the physical pro
perties of actual electron-electron (or hole-hole) pairing forces in s
uperconductors. However, it lends itself to a simple, pedagogically us
eful solution at the Cooper problem level in terms of combined analyti
cal, graphical and numerical techniques which are standard.
