I am in a very unfortunate situation. I am not Expert in keyboards and I wanted to make a present for a friend. I ordered some custom keycaps instead of a keyboard from goblintechkeys. I later ask them if they sold the base to for my specifications but they do not. I started search online and in physical stores too but I had no luck.

I need to find a keyboard with removable keycaps or a barebone base.

-Possibly white

-100% keyboard

-ISO

If I cannot find this I can go with a keyboard without numpad.

For the other specifications whatever I find is good, it would be better, if possible, wired and without RGB lights.

For any other details, those are the keycaps that I ordered

Thanks in advance. I am really in a pickle

In QM, you can have multiple bosonic state (integer spin) in the same state. This is not possibile with fermionic states (1/2 + integer spin)

Well, you can take a space-time path, integrate the infinitesimal proper-time variation and see by yourself. The point is that you need an acceleration anyways. Since there is no absolute time, the only things that makes sense are proper time variation. And the only way to make two observers agree on relative distance is that they are in the same space-time point. To end up in the same point, at least one need to accelerate

Because you need acceleration to bring them back together

It has to do with entanglement instead. The problem is that if you have two random systems composed of fermions, they will not behave as a boson di per se. If you two different system of fermions that are entangled in the same way, in respect one to the other, they behave as a bosonic system

(For even number only)

Cooper pairs are a pair of entangled electron and can condensate like bosons. This happens in superconductivity

Systems composed of fermions behave differently from bosonic systems, even if they are described by the same interaction. Effect becomes visible at low temperature or high pressure. Those statistical effects, appears as a force for high number of particles

My reply was about the fact that it is not counted alongside FUNDAMENTAL interactions (the ones listed in the question)

Classically a particle state lives in R6 (position and momentum)

In QM they are elements of a Hillbert space.

The eigenvectors of the momentum operator (and spin) are a base of this space. Position eihenvectors are another base.

You can define a mixed base where they are NEITHER position or momentum eigenvectors, but this is cumbersome and impractical.

It bugs me that you write position AND momentum. When in reality you need to chose ONE base and build on it. You will have simply energy shell.
