Hi,I m trying to find out,what is imaginary unit/number.How to imagine it.I was reading many articles and analogies,but I still have some questions to get better idea what is it.So I m going to write some points,that are mystic for me.
My question is maybe more philosophic than mathematic but:What was the impuls to invite imaginary number.Was it so,that one day mathematicians made a decision to make number ,,i"?From out of blue,or how?It seems to me,like mathematicians can define everything,what they want.But if negative times negative gives positive.And positive times positive gives us positive,then it is impossible(but we know that it is not true,but pretends we :) )and enough.We cannot do with x^2=-1 nothing.And that s the fact.But clever mathematicians said:,,Well come on,make a little convention and i^2 will be equal to -1."So it seems,like mathematians adjust math,how they need.----So I hope,that you understand where I m going...
Thanks a lot for patient
