PeroK reacted to PeterDonis's post in the thread High School Classic question regarding the nature of quantum tunneling with
Like.
Sorry, but that's not what PF is for. We are here to help people understand mainstream science. That includes mainstream QM, but, as has... -
Can you state where this comes from? The frame work of your question looks like Ai

PeroK reacted to A.T.'s post in the thread Undergrad Different result with kinetic energy and momentum when a bullet hits a target with Like.
Yes, as allready explained by others. The bullet would still be moving (together with the target), so it would still have some kinetic...

PeroK reacted to haruspex's post in the thread Undergrad Different result with kinetic energy and momentum when a bullet hits a target with Like.
Because you are specifying an impossible combination of conditions. In an actual one dimensional collision, there are two unknowns, the...

PeroK reacted to mitchell porter's post in the thread Graduate Quaternionic Rays instead of Complex with
Informative.

PeroK replied to the thread High School Classic question regarding the nature of quantum tunneling.Theories can only be tested so far. It's an open question whether a cat could tunnel through a wall by sheer randomness. The probability...

PeroK reacted to FactChecker's post in the thread High School Classic question regarding the nature of quantum tunneling with Like.
You are asking about something that is so unlikely that any theories will/have remained unverified for a very long time (billions of...

PeroK replied to the thread High School Classic question regarding the nature of quantum tunneling.Just to add that electron tunnelling is a specific phenomenon that is useful in microelectronics. But, everything about the macroscopic...

PeroK reacted to DaveC426913's post in the thread High School Classic question regarding the nature of quantum tunneling with Like.
This is not endemic to QM. Classically, there is a non-zero chance that all the air molecules in your room end up on the left side of...

PeroK reacted to Sagittarius A-Star's post in the thread Undergrad Why is the Lorentz Force always perpendicular to velocity? with Like.
As I understand your scenario, the object is moving in frame ##S## not parallel and not perpendicular to the conductor. But the force...
-
PeroK replied to the thread Undergrad Why is the Lorentz Force always perpendicular to velocity?.Whether two 3D vectors are perpendicular depends on the frame of reference. Imagine a particle is moving along the x-axis and the force...

PeroK reacted to pervect's post in the thread Undergrad Why is the Lorentz Force always perpendicular to velocity? with Like.
It seems to me that if you define the Lorentz force as being only due to the magnetic field, the Lorentz force is perpendicular to the...

Being unable to understand a proof I gave ChatGPT another chance : please explain this to me. Its mien is today quite different from...

PeroK replied to the thread Undergrad Formalizing infinity sets.In simple terms, if the set of natural numbers is finite, then there is a largest whole number. If not, then the set must be infinite...
