Let’s use our pym particles to shrink into the microverse……
At this level, physics becomes weird— really weird. The laws governing our classical (regular) world breaks down. We will need a new system— new mechanics if you will— to make “predictions”(lol, you’ll soon see why this is funny). Why do we need a new framework you ask?….
The Ultraviolet catastrophe
There’s something caed the “black-body radiation” (funny name lol). It just means the energy emitted by an object naturally. Essentially, the natural response of an object with a lot of energy. A black-body is a perfect absorber and emmiter of thermal energy.
It is a priori that the higher the frequency of a particle, the higher energy it should emmit. Because energies correspond to frequencies. However, this is not the case it would mean that particles with frequencies in the UV range would have a near infinite amount of energy. This will suggest that heating a metal to a high enough temperature may cause gamma rays to be emmited.
Max Planck resolved this problem by assuming Energy was not continuously absorbed/emmited, but in discrete chunks(called quanta). So
Energy=nhf
Where h is Planck constant, f is the frequency, and n is an integer.
Schrödinger
With the development of this new framework arose the need to have equations that can make predictions(again, lol). Just as Newton developed his Newtonian framework with Force and mass. However, things are a little different in Quantum Mechanics. Here, we need to work with operators. Scrodinger’s equations makes use of the energy operator specifically.
Pause. Not sure if I want to go into the nit and grit of this stuff: Eigen functions, Fourier Analysis, interfermometers etc.
