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...

weirdoguy reacted to Dale's post in the thread Graduate Horizontal component of the electric field of an infinite uniformly charged plane with Like.
No, they aren't correct with respect to the vertical component. To see this, consider the spot exactly in the center of a charged...

weirdoguy reacted to DaveC426913's post in the thread High School Is there anything in the Universe that is not fundamentally made up of matter? with Like.
Which is why we use math. Math is not ambiguous. And why we don't concern ourselves with the semantics of words. Words are ambiguous...

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.
It is not surprising how often people end up disagreeing, bickering, and even fighting over things like different interpretations, in...

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.
As long as there is a realisation that your theories are not completely correct, then all is well and good. Words are used in...
-
weirdoguy reacted to pervect's post in the thread Undergrad How many sorts of time are there in physics? with Like.
Some recent threads inspired me to want to make a list of the different notions of time we need in physics (As I write this, I am...

weirdoguy reacted to wrobel's post in the thread Undergrad The vector to which a dual vector corresponds with Like.
The book is pointless. The author yanked random bits from differential geometry, linear algebra, calculus, and physics. It’s the best...
