Because these are the intrinsic properties of the particles & is fundamentally different from spatial dimensions of the system (i.e. don't have spatial extent in the way of position & momentum operator have).

But there are commutation relations over finite vector spaces as well, e.g. for angular momenta or spin.
Can you guess why they don't lead to contradictions?

Our results show that asymmetry can improve the efficiency of the erasure process, while remaining consistent with the general free-energy bound of the second law, ⟨W⟩ ≥ ΔF. (5/5)
Our paper is now in PRR . Here is a brief summary of what we did :
Modern computers store information in binary form, where each memory unit (bit) takes the value 0 or 1. Before new information can be written, existing data must often be erased. (1/5)

We investigate a physical model where the two memory states correspond to the two wells of a bistable potential. Unlike conventional symmetric models, we consider an asymmetric setup, where the widths of the wells is different, that occupy different phase-space volumes.(4/5)

Researchers from @iitbombay and @IIT_Mandi have built twin robots capable of replicating the run-and-tumble moving mechanism used by many microorganisms. The study published in @PhysRevLett mimics the complex locomotory mechanism in the most minimalistic robots, opening opportunities in building microscopic machines for healthcare.

It is indeed a matter of great joy to spend almost two days with your teacher after five years—and an even greater joy when he goes to your whiteboard, discussing physics and inspiring your students.
Heartfelt thanks to Sriram for a wonderful colloquium at

A young Indian scientist was told by the director of his institute that he must stop working on his chosen field. Take up a field of the director's choosing, or leave.
But he kept at it in his spare time and produced a game-changing paper.
His name was Amal Kumar Raychaudhuri.
