Matterwave's latest activity
-
Matterwave replied to the thread Spacetime manipulation vs a fall..I mean, sure. "My spacetime is rigid so it enforces unchanged geometry" is a sentence that can be written. You can include this in your... -
Matterwave replied to the thread Spacetime manipulation vs a fall..Yeah, again, you can come up with whatever rules you would like, I'm not trying to constrain you. I'm only giving my opinion on what... -
Matterwave replied to the thread Undergrad Is infinity a necessary concept?.Wikipedia article for the ##1+2+3+4+...## that I think the OP was talking about: https://en.wikipedia.org/wiki/1_+_2_+_3_+_4_+_⋯ Note... -
Matterwave replied to the thread Undergrad Meaning of division by non-whole real numbers.Yeah, I agree that if given segments x and y and 1, then we should be able to construct xy, x/y. But I wonder if the ancients were so... -
Matterwave replied to the thread Undergrad Is infinity a necessary concept?.Do you mind rephrasing? I'm not sure I understand. The series in my post is defined for an open region ##\text{Re}(s)>1## -
Matterwave replied to the thread Undergrad Is infinity a necessary concept?.I think the OP is probably referring to several pop-sci content (YouTube videos from Numberphile comes to mind) where it is "shown" that... -
Matterwave replied to the thread Undergrad Is infinity a necessary concept?.If by logical difficulties you mean logical contradictions then yes. We build our systems of mathematics on the principle that we can't... -
Matterwave replied to the thread Spacetime manipulation vs a fall..I might just point out that for me as a reader and general enjoyer of physics, the two parts of your two posts that seem most... -
Matterwave replied to the thread Undergrad Is infinity a necessary concept?.I mean, the fact that the world of mathematicians generally work with infinities on a daily basis should tell you something about its... -
Matterwave replied to the thread Undergrad Meaning of division by non-whole real numbers.Genuine question here as I am not so familiar with this view of things. Would this bring into question constructable vs... -
Matterwave replied to the thread Double slit experiment with single electrons and no observation.The apprehension comes because the word is indeed ambiguous, and there has been a sea of literature and thought experiments which show... -
Matterwave replied to the thread Undergrad "The wavefunction never collapses".By Penrose interpretation do you mean the Penrose-Diosi model where gravity causes collapse? That one should actually make some... -
Matterwave replied to the thread Double slit experiment with single electrons and no observation."Observation" is a rather loose term. Within the standard Copenhagen interpretation, it is not given much more sharpness than that it...
