The wave packets interpretation reminds me of Schrödinger, but I don't remember exactly why it was dropped back in the day (circa 1940). Sorry I'm so sloppy on

The wave packets interpretation reminds me of Schrödinger, but I don't remember exactly why it was dropped back in the day (circa 1940). Sorry I'm so sloppy on these topics, I never studied them formally ("mathematically" if you will -- think what I did more like a "history of quantum mechanics" course) and it's also been a long since last read about.
