KE of photo-electron and nominal interest rate

AI Thread Summary
Einstein's formula for the kinetic energy of a photoelectron, expressed as KE = hν - φ, illustrates that energy from radiation is partially used to overcome the work function (φ) required to release an electron, with the remaining energy contributing to its kinetic energy (KE). Similarly, the formula for nominal interest rate, i = r + L, indicates that the interest earned is diminished by inflation (L), with only the real increase in purchasing power (r) benefiting the individual. The discussion highlights a conceptual mapping between these equations from physics and economics, emphasizing how both illustrate the idea that a portion of energy or value is "wasted" in overcoming barriers, leaving only a remainder that contributes to effective energy or purchasing power. This analogy underscores the interconnectedness of different scientific principles.

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.

Just ONCE, I wanted to see a post titled Status Update that was not a blatant, annoying spam post by a new member. So here it is. Today was a good day here in Northern Wisconsin. Fall colors are here, no mosquitos, no deer flies, and mild temperature, so my morning run was unusually nice. Only two meetings today, and both went well. The deer that was road killed just down the road two weeks ago is now fully decomposed, so no more smell. Somebody has a spike buck skull for their...
