Why when explaining/introducing QM things get explained with the <bra|ket> complex vectors... then somewhere in between they start using functions (psi)..(adsbygoogle = window.adsbygoogle || []).push({});

It gets confusing when epxlanation start switching between them back and forth...

My understanding is they are the same thing...

Is there some purpose of this exercise...

Similar thing with the Operators... when the explanation goes around the the braket vectors.. they use matrices... then the moment find operators to be differential operators we switch to functions.

I understand it is logical to do this, but why we don't they stick with one of the mathematical abstraction and go with it the whole time..

sorry if it is a stupid question.. I'm neither mathematician nor physicist.

May be that is why they are confusing to me ;)
