weirdoguy replied to the thread Undergrad Momentum measurement and uncertainty.Unfortunately, I'm not talking about uncertainty principle besides this sentence: I gave explicitly the definition of what I (and... -
weirdoguy reacted to wrobel's post in the thread High School Just a cool high school problem with
Like.
Honestly, I'm a bit shocked by everything that's going on here. $$x(t)=-R\omega t\sin\varphi+R\cos \varphi$$ $$y(t)=-gt^2/2+R\omega... -
weirdoguy reacted to bhobba's post in the thread Undergrad Particle vs Wave Interpretations of QM with Like.
It doesn't. It does resolve some things, like what a particle is. Its main advantage is that we know ordinary QM is wrong, e.g., it...
-
weirdoguy replied to the thread Undergrad Momentum measurement and uncertainty.Yes, it means average of measurement data. And for only one measurement, this average is the measured value. Hence uncertainty is zero.

weirdoguy reacted to anuttarasammyak's post in the thread Undergrad Momentum measurement and uncertainty with Like.
I have thought that <> for uncertainty relation means average of large number of measurement data, ideally infinite. [edit] more...

weirdoguy replied to the thread Undergrad Momentum measurement and uncertainty.Do you understand the definition of uncertainty? Do you know what variance is? What standard deviation is? I gave you the only definion...
-
weirdoguy replied to the thread Undergrad Momentum measurement and uncertainty.Because it gives zero for single measurement. Do the math, it's simple. For single measurement...

weirdoguy replied to the thread Undergrad Momentum measurement and uncertainty.Uncertainty is not about how exact is a single measurement. Uncertainty is defined as: ##\Delta...

weirdoguy reacted to wrobel's post in the thread Undergrad A differential geometry question from continuum mechanics with Like.
"Not making physical sense" and "not making geometrical sense" are in fact two sides of the same coin

From the perspective of thermal radiation, all surfaces of the stainless steel chamber will emit electromagnetic radiation, including...

weirdoguy reacted to Amazed's post in the thread What lies beyond the furthest object in space? with
Haha.
Although what really happens and occurs contradicts this made-up model completely. -
weirdoguy reacted to wrobel's post in the thread Problem-Solving Strategy for Dynamics Problems with Like.
For high school, such a problem-solving strategy is OK, but at the university level, it is too weak. For example, this is a mistake...

weirdoguy reacted to danieltanfh95's post in the thread Graduate Literature on photons and observers with
Skeptical.
I am requesting help specifically on "has anyone in the foundations literature explicitly argued that a single free photon cannot serve... -
weirdoguy reacted to danieltanfh95's post in the thread New member introduction -- matter wave realist with Skeptical.
Standard QFT refers to Dirac fields as "matter fields", which is also what I am referring to, but using matter-wave field wrt to...

weirdoguy replied to the thread New member introduction -- matter wave realist.There is no such thing in physics, so I think you should reconsider what you are working on :wink: Anyways, welcome to PF!
