This is my first post to the physics forum. I am completely new to quantum physics and have just gone through lecture notes on the Schrödinger equation, infinite square well, hydrogen atom and angular momentum etc.

I am currently starting on the Stern-Gerlach experiment, bras and kets via Sakurai’s Modern Quantum mechanics book. In general terms,

• Why do we have to use kets, bras and operators (Vectors Spaces) and for what?

• What’s their significance both mathematically and physically?

I suspect that as I study it further it might become clearer but at the moment I am going in blind.

Thanks
