👉 Spissus is a term used in the context of quantum mechanics, specifically in the realm of bosons and fermions. The term "spissus" refers to the phenomenon where particles can be thought of as being in two separate states simultaneously, one being a boson (a particle with mass) and the other being a fermion (a particle with charge). This is an important concept in quantum mechanics because it allows for the possibility of multiple states that cannot be explained by classical physics.
