Reader questions Cauchy-Schwarz proof in quantum mechanics textbook

Original: Alguien aquí que sepa explicarme esta demostración de cauchy-swartz hecha en el libro de Claude Conan? No me parece lo s

A student is asking for help understanding the Cauchy-Schwarz inequality proof in Claude Cohen-Tannoudji's quantum mechanics textbook, saying the argument does not feel logical or intuitive. The confusion centres on why the proof assumes a ket of psi in a particular way and how the value of lambda is chosen in the demonstration.

Why now: Students of quantum mechanics often struggle with the formal Dirac-notation proofs in the Cohen-Tannoudji reference text, prompting requests for clearer explanations.
