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.

Similar to the 2024 thread, here I start the 2025 thread. As always it is getting increasingly difficult to predict, so I will make a list based on other article predictions. You can also leave your prediction here. Here are the predictions of 2024 that did not make it: Peter Shor, David Deutsch and all the rest of the quantum computing community (various sources) Pablo Jarrillo Herrero, Allan McDonald and Rafi Bistritzer for magic angle in twisted graphene (various sources) Christoph...
Thread 'My experience as a hostage'
I believe it was the summer of 2001 that I made a trip to Peru for my work. I was a private contractor doing automation engineering and programming for various companies, including Frito Lay. Frito had purchased a snack food plant near Lima, Peru, and sent me down to oversee the upgrades to the systems and the startup. Peru was still suffering the ills of a recent civil war and I knew it was dicey, but the money was too good to pass up. It was a long trip to Lima; about 14 hours of airtime...
