Matterwave's latest activity
-
Matterwave replied to the thread Undergrad Heat radiation in vacuum.Ah, my mistake. :) -
Matterwave replied to the thread Undergrad Particle vs Wave Interpretations of QM.I didn't mean to derail the conversation with a cheeky reference to the moon lol. But for the record, I am staunchly against the...
-
Matterwave replied to the thread Undergrad Heat radiation in vacuum.Why radiative heat transfer? Although radiative heat loss does occur, conduction or convection would probably do the job here? I say...

Matterwave reacted to Demystifier's post in the thread Undergrad Particle vs Wave Interpretations of QM with
Like.
Is the Moon itself the same thing as its wave function? If not, then what exactly the Moon is? Can the Moon itself be described by a... -
Matterwave reacted to Demystifier's post in the thread Undergrad Particle vs Wave Interpretations of QM with Like.
Yes, but that is exactly the point. Some of the most important scientific insights were inspired by questions that brought confusion.

Matterwave replied to the thread Undergrad Particle vs Wave Interpretations of QM.Yeah I was just making a tongue in cheek reference.

Matterwave reacted to PeroK's post in the thread Undergrad Particle vs Wave Interpretations of QM with Like.
The idea that things do not exist if not observed is one of the greatest misunderstandings of QM. The Moon exists continuously, but...

Matterwave replied to the thread Undergrad Heat radiation in vacuum.Is the tray just floating there? If not, conductive heat will flow through whatever support is holding up the tray. As far as...
-
Matterwave replied to the thread Undergrad Particle vs Wave Interpretations of QM.So the moon is indeed there even when I'm not looking at it. 🤔

Matterwave replied to the thread Seeking clarity on the physical definition of an observer.The section of this text maybe most fitting for the current discussion is section 6.10

Matterwave reacted to bhobba's post in the thread Seeking clarity on the physical definition of an observer with Like.
Very nice discussion. Kudos. Just as an aside, a link to the prototype QFT, What Is A Photon, so those unfamiliar can get a general...

Matterwave reacted to PeterDonis's post in the thread Seeking clarity on the physical definition of an observer with Like.
Unfortunately, as I said, such a state, if it's obtained by applying the field operator you wrote down to the vacuum, doesn't look...
-
Matterwave replied to the thread Seeking clarity on the physical definition of an observer.Gotcha. I still lacked precision in my statements. By "single particle state" I just meant a state which would have eigenvalue ##1## for...
-
Matterwave replied to the thread Seeking clarity on the physical definition of an observer.The bolded part seems to me to be quite a simplification. In a free, non-interacting, QFT, particle states are created by some creation...

Matterwave replied to the thread Seeking clarity on the physical definition of an observer.I recently read Bertrand Russell's History of Western Philosophy. His ending section on QM was horrendously outdated. He was using...
