You can learn how to do that, even find a way to type "sigma", but more importantly, it best benefits readers, not writers, so you don't need to learn to type it

no it's not, where would you get clarity from is all the clarifying literature for these notions use the actual math notation σ?
> "n" and a constant "η". Just begging for confusion
looks very distinct, one is obviously mathy, another isn't
