      It does? That doesn't match the way I think about linear algebra at all.

      Interesting… did you read the jadagul post? “The entire subject is, like, four actual facts, each of which is repeated twenty times in slightly different language.”

      The post was nice enough, but I didn't really get much from it. It's possible my calibration may be off, after years of quantum information theory. Proving linear algebraic facts became a sort of ground state, for relaxation purposes.

      Ah, right, yes—something that would be helpful to a sophomore first encountering linear algebra would not come as a revelation to you!

      That's true. It's perhaps the one part of mathematics where I feel completely at home. Of course, I'm still ignorant of vast parts of linear algebra. But I feel assured with the basics; certainly those points of view are completely natural (though 6 is ambiguous).

      I never went beyond the basics of abstract algebra… logic is the one branch of math where I really feel at home

      Logic always seems like black magic to me. I once notionally TA'ed a class on logic; I felt like quite the imposter, since I didn't understand the material at all deeply.

      This is funny, how different sorts of math are natural for different people! I’d love to know whether it correlates with Big 5 personality traits, for instance

      Are you familiar with the theory that it correlates with which way you eat corn on the cob? http://bentilly.blogspot.com/2010/08/analysis-vs-algebra-predicts-eating.html …

      I have no where near enough mathematical education to say whether I prefer algebra or analysis, though my guess is the former. But I don't eat corn on the cob either way because I don't eat it systematically. More like a spreading blot of eatenness.

      You may have a promising career as a logician ahead of you!
