-
PeroK replied to the thread I Energy*time uncertainty for particle decay.PS my Internet is down. I think I posted a quotation from Griffiths on this recently if you can find it. -
In addition to #2: Elementary particles don't spin. Many of them have non-classical degrees of freedom which are named "spin", because...
-
All elementary particles have an intrinsic spin/angular momentum. The fact that particles spin at all is due to Special Relativity...
-
First-year maths undergraduate. I’m interested in real analysis, algebra, calculus and most areas of abstract mathematics. Not a big fan...
-
PeroK replied to the thread I Energy*time uncertainty for particle decay.Introduction to QM by Griffiths explodes that myth. There are a lot of sloppy textbooks it appears.
-
PeroK replied to the thread Minimum mass of a block.PS if we are being totally precise, doing the mathematical calculation, we will find the maximum mass of A that will not move block B...

PeroK replied to the thread Minimum mass of a block.Let's fix the mass of block B (##M##). Start with a small mass of block A ##m##. This moves up and down. The maximum force in the...

PeroK reacted to ojitojuntos's post in the thread Help me understand why “Block Universe” is not scientifically proven with
Like.
You are correct. While my questions were mostly philosophical, it was very enriching for me to read you and others who engaged with me... -
PeroK replied to the thread Help me understand why “Block Universe” is not scientifically proven.For me, these questions are more philosophical than physical. And there are, effectively, no answers in philosophy - only opinions and...

PeroK reacted to PeterDonis's post in the thread I Energy*time uncertainty for particle decay with Like.
There is no such thing. Energy and time are not complementary observables, so there is no uncertainty relation between them. Indeed...

PeroK replied to the thread Making the denominator of a certain fraction real.##zz^*## is always real.
-
PeroK reacted to PeterDonis's post in the thread I Is there a bad intuition or bad explanation in quantum entanglement? with Like.
So basically, on the "principle account" view, entanglement in QM is viewed as analogous to, say, relativity of simultaneity, length...
-
PeroK replied to the thread Different way to find center of mass of Hollow hemisphere.Maths and physics are hard enough without doing things the wrong way!
-
PeroK replied to the thread Help me understand why “Block Universe” is not scientifically proven.Let's take non-determinism to mean that two identical experiments can have different outcomes. The universe as a whole is essentially a...

PeroK reacted to Filip Larsen's post in the thread On writing with AI: The Devil is in my foyer, do I invite him in? with Like.
I think there is a difference between using the AI as an advanced search machine where you ask it for specific factual data that you can...
