KE of photo-electron and nominal interest rate

[Hall]

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.

The mapping, that I have established

Or, more generally:

(Some of it) + (The rest of it) = (All of it)
