If you want something to puzzle over (and cf my last comment re E&H): regarding the previous problem with a possible way to violate Δp Δx > ℏ/2, it seems to me that existing, demonstrated "interaction-free measurements" would already do this! Prepare the object in defined momentum, then "find it" with IFMs, have no affect ... Well?<br /><br />PS: Neil Bateshttps://www.blogger.com/profile/04564859009749481136noreply@blogger.comtag:blogger.com,1999:blog-22973357.post-49122073026172056982012-01-12T06:54:55.051-05:002012-01-12T06:54:55.051-05:00Hi Bee,
