Congratulations on typing ΔpΔx=ℏ, Whenever I see that in a physics video on YouTube, one more such outrage and it's back to a Marilyn Monroe movie. Same for a book on quantum mechanics. If they have an application of Parseval's theorem, then be clear about it and trot it out. But usually the Δp and Δx are not defined clearly or defined at all. I just can't take such sloppiness seriously.
