Anyway, I only accept the existence of i and j and no more quaternions. I pose the question. I understand that Dirac Equation was written in quaternions only but its predictive power was reduced. Every year I come to wrestle with the Demons of Science. Try to connect some part of physics with mathematics or physics with biology etc.
Progress is slow.
This is how progress should be. Although I should not be so gloomy for in the year 1990 on 7Nov I won a war with the Demon, for I discovered the Atom Totality. More accurately the Lord 231Pu put that thought into my mind, and I only a servant avatar of 231Pu. Never let arrogance ever win over humility. But let me tell you how my attitude or mindset is before I wrestle with any particular demon.
