AThe news has recently became viral that physicists have discovered a geometrical object that simplifies a lot our models of quantum physics has recently became viral. For an outsider like me, it is difficult to actually understand the significance of thatthis finding.
Is it actually a new model that literaly makes every quantum physics book obsolete -, or is it just a tool for a very specific calculation or effect that barely change everythingchanges anything else onin the field?
