There is was a recent interesting article in Quanta Magazine about 'paraparticles' (https://www.quantamagazine.org/paraparticles-would-be-a-third-kingdom-of-quantum-particle-20250411) as a new type of particle. The article describes how these particles (strictly theoretic at this point) are different from current particles and derive from not squaring values in current measurements. When a measurement is squared, there are two possible solutions (one positive and one negative). Not squaring provides a means of identifying aspects that 'disappear' when squared.
I have given a couple presentations (and papers) suggesting we need new mathematical tools to expand science (and mathematics). In particular is the need for a new, more powerful numeric system that could provide single values for complex numbers.
Paraparticles research might find such a system very helpful, since it could distinguish between any complex values without needing to square results (to get a non-complex or 'Real' result) and therefore distinguish between measurements of paraparticles.
I note that complex numbers do not apply to 'real' measurements, since we do not know what to do with the 'imaginary' part (hence we square it to get rid of this part or simply drop it, as for some electronic measurements).
This is the first direct potential application I have seen for the need for such a complex numeric system.
I would be interested in other's comments.
