KE of photo-electron and nominal interest rate

In summary, the formula for kinetic energy of a photo electron, as stated by Einstein, shows that a portion of the energy provided through radiation will be used to overcome the work-function, leaving the remaining energy to give the electron some speed. Similarly, the formula for nominal interest rate takes into account the real increase in purchasing power and inflation rate, showing that a portion of the interest received will be used to cope with inflation, with the remaining increasing purchasing power. This mapping between the two equations reveals how they almost completely overlap and can be seen as "some of it" and "the rest of it" combining to make "all of it."

Einstein's formula for kinetic energy of a photo electron is
$$ KE = h\nu - \phi$$
$$ h\nu = KE + \phi$$
Which basically says whatever energy you provide through radiation, a part of it will be used (but I would like to say 'wasted') in overcoming the work-function (that is in cajoling that electron to leave the bereavement and come out) and then the energy left will give it some speed.

The formula for nominal interest rate ##i## is
$$
i= r + L$$
##r## is the real increase in purchasing power (in %) and L is the inflation rate. So, whatever extra money the bank or government gives you as interest, a part of it will be wasted in coping up with the inflation and only remaining part will influence your purchasing power.

The mapping, that I have established above between two different equations of two very different sciences, is not any ground-breaking or even a knit-pick but just see how beautifully do they map, they almost get completely superimposed.
