weirdoguy reacted to arivero's post in the thread Graduate Are Almost Commutative Geometries a sort of Kaluza Klein limit, or no? with
Like.
I have always taken for granted that the extra algebra ##A## in an almost commutative geometry ##C(M)\otimes A## was not only Morita... -
weirdoguy reacted to PeterDonis's post in the thread Undergrad Looking closely at the descent into a black hole with Like.
Whatever they tell you is irrelevant to what you say you are trying to calculate. I showed you in post #40 how the non-Euclideanness...

weirdoguy reacted to PeterDonis's post in the thread Undergrad Relativity, time, and quantum mechanics with Like.
On what basis are you making this claim? The "different momentum components" are not observables; they are just a convenient basis in...

weirdoguy replied to the thread Undergrad Looking closely at the descent into a black hole.I still see no math, only bunch of words.

weirdoguy reacted to .Scott's post in the thread Undergrad Looking closely at the descent into a black hole with
Skeptical.
In response to: "because of the curved space time geometry, that inside surface would appear flatter that expected". That's just the... -
We get hundreds of threads like this every year. You don't see them because they get deleted. What you wrote would be slightly less...

weirdoguy reacted to mad mathematician's post in the thread Graduate Did Stephen Hawking fix his numerical mistake? with Like.
Well this book is more semi-popular. Someone who didn't even take a UG course in GR wouldn't understand the terms being used there. I...

weirdoguy reacted to PeterDonis's post in the thread Graduate Quantum measurement problem (ie double slit experiment) question with Like.
Then you can't get single outcomes. Yes, but using a "reduced state" at all already assumes that you have a single outcome--without...

weirdoguy replied to the thread Undergrad Ships passing each other at near light speed.Google "relativistic velocity addition".

weirdoguy reacted to Ibix's post in the thread Undergrad The paradox of symmetrical time dilation with Like.
Seen in terms of geometry, it is closely analogous to two cars driving at equal speeds ##v## down straight roads that make an angle...

weirdoguy reacted to PeterDonis's post in the thread High School Is there anything in the Universe that is not fundamentally made up of matter? with Like.
And it seems as though your only reason for starting this thread in the first place was to try to get to a point where you could present...

weirdoguy replied to the thread High School Is there anything in the Universe that is not fundamentally made up of matter?.Oh please, stop this nonsense. Even in ordinary language there are tons of words that have multiple meanings, depending on the context...

weirdoguy reacted to Amazed's post in the thread High School Is there anything in the Universe that is not fundamentally made up of matter? with
Sad.
So, to you 'matter', itself, is a philosophical category. Which I find amazing to be a view and perspective within a physics forum... -
weirdoguy replied to the thread High School Is there anything in the Universe that is not fundamentally made up of matter?.@Amazed, could please stop telling me, and other physicists, how to do, understand and think about physics? You don't go to surgeons and...

weirdoguy reacted to Amazed's post in the thread High School Is there anything in the Universe that is not fundamentally made up of matter? with Sad.
An adult has to understand what meaning is first before it can learn how the Universe works and what the Universe is made up of and made...
