Nnasu reacted to Demystifier's post in the thread Undergrad Necessary conditions for the uncertainty principle with
Like.
Nice question and apparent paradox, let me demystify it. To simplify the math I will work in units ##\hbar=1##, so that position and... -

Like.
Which, by writing ##q=x##, ##p=y##, becomes the usual quantum mechanical continuity equation. So pre-quantization, at this level, is... -

What is the evidence that it does? -
Nnasu reacted to PeroK's post in the thread Very tricky problem from Spivak's Calculus, Ch. 4 & 5: Graphs/Limits with
Like.
Hint: try to sketch out a proof first. Don't dive into ##\epsilon-\delta## until you know what you are trying to do. -
Nnasu replied to the thread Voltage vs Distance graph for a given E vs D graph.Yeah, qualitatively it may be, for the first graph of E is x. But these points (a and b) are from some other problem, right? Also, as...

Nnasu replied to the thread Voltage vs Distance graph for a given E vs D graph.You cannot treat this type of problem without concepts from calculus. You can do it without using the word "calculus". But the concepts...

Nnasu reacted to Dale's post in the thread High School Is it correct to state that all measurements count photons? with
Like.
There is a very big difference between using photons and counting photons. -
Nnasu reacted to vela's post in the thread Engineering Why wasn’t gravity included in the potential energy for this problem? with
Like.
Given the method, I think you should include the potential energy due to gravity (though you should've had ##-mgx##). It feels a bit...
