The wave packets interpretation reminds me of Schrödinger, but I don&#x27;t remember exactly why it was dropped back in the day (circa 1940). Sorry I&#x27;m so sloppy on these topics, I never studied them formally (&quot;mathematically&quot; if you will -- think what I did more like a &quot;history of quantum mechanics&quot; course) and it&#x27;s also been a long since last read about.
