Re: Old news

The DUHLY MAIL is a bit confused about QM.

They are using both the metaphor of a "particle having a certain position and thus being able to be labeled as having passed a certain point" and a "particle being a complex-valued probability density function (aka 'wave' to the charver public though this has nothing to do with a wave front, right and center). You can't have it both ways.

That the 'wave' changes depending on whether you drop a grating into its environment before you extract the position information from said wave is exactly as it should be according to even naive QM.

For the macroscopic object, you exponentially quickly collapse to the fat-arsed behaviour of massive daily objects: HERE and NOW become very important indeed.
