James explains quantum millinery

Rebecca:
I'm putting on my potential congratulatory hat

Scott:
...so it's a kind of Schrodinger's Hat?

Rebecca:
Yes, just like that

Scott:
Its a little known fact that Dr Seuss' 'Cat in the Hat' was a scientific paper describing an attempt to combine Schrodinger's two thought experiments, namely Schrodinger's Cat and Schrodinger's Hat.

James:
*observes Bec's hat*
Oops, I think I just collapsed the waveform

Scott:
Was anyone wearing the hat at the time? Have we suffered any skull blow-outs?

James:
You're obviously ignorant of the standard theories of quantum millinery. If the hat was in a state of quantum flux, both there and not there, then the observation would not cause it to simply appear. The observation will collapse the waveform and at that point the hat will have _always_ been there, even during the period when it also wasn't.

Scott:
So old photographs of a hatless you will suddenly show you wearing a fineshiny tophat?

James:
Only if the photographer took your photo without looking at you and nobody looked at any of the resulting photos.

Scott:
Wow, quantam millinery is more complicated than I had ever imagined!
