A machine gun, Russian, where every bullet seeks the own target? If I had to kill every idiot on this planet, the Sahara would turn green with shame. But you're probably not even usable as fertiliser, you're just hazardous waste. Mathematical hazardous waste. A binomial is the sum or difference of two monomials. In zoology and botany, a ‘binomial’ is defined as a name that consists of two parts: a genus name and a species name. For example: "stupid Russian aggressor". Or is this a trinomial? Species "aggressor" genus "Russian" description: "in a totally stupid, senseless and criminal war on Europe in the Ukraine". Okay - perhaps this is no trinomial - but a complex Hilbert space full of absolute stupidity and absolutelly senseless aggressions. ... But then who is the anti-unitarian operator? Putin for sure and Trump ?¿? or both?
