Hey, I am currently reading over the linear algebra section of the "introduction to quantum mechanics" by Griffiths, in the Inner product he notes: "The inner product of two vector can be written very neatly in terms of their components: <a|B>=a1* B1 + a2* B ... " He also took upon the generalisation that any scalar is a complex number.(adsbygoogle = window.adsbygoogle || []).push({});

I do not understand how is it that the components of a are conjugates of the complex number , because of the * symbol means. When he writes usual dot products he does not use * as a multiplication symbol, in the book context it has only been treated as the conjugate symbol, so I don't consider the possibility of * standing for 'multiplication'.
