## Main Question or Discussion Point

I found this video series on linear algebra youtube from this guy named Norman J Wildberger he seems really fantastic and intuitive. In addition he also seems to have videos on differential geometry, hyperbolic geometry, algebraic topology, and others. However he has this pet peeve against the real numbers. I am not enough of an expert to know whether or not he is a crank, I dont even really care (right now) if he is, I just want to know if anyone can confirm that he is legit, i.e. his material is accurate and his whole anti-real numbers doesnt interfere with the rest of his math.
