I love these posts! They make me mad :) and that means I’m learning something new. For example, in this post I read “i,j and k are the square roots of -1” and I became angry like the country bumpkin being taken for a ride by his city cousin. Are you pulling my leg? Are you making fun of me?
Haha, yes! Quaternions are a lot of fun, um, if strange new algebras are a thing you find fun. I loved the quote:
There is still something in the system which gravels me. I have not yet any clear views as to the extent to which we are at liberty arbitrarily to create imaginaries, and to endow them with supernatural properties
… because it’s nice to know the original inventors had the same first reaction I did. :)
