Adding something that is finite an infinite amount of times would not lead to a finite value, it would lead to an infinite value, so maybe that is the answer to the your first question. The second question is about limits (which I could use help with), but x/x = 1, so maybe there is no need to...

What is infinity times zero? Isn't it zero? I mean, infinity times zero is the same as zero an infinite amount of times, and adding zero infinitely would give zero because even though zero is always being added, this process is the same as nothing ever being added to zero.

Thanks. Then why do we describe physical objects with coordinates (i.e. points)?

If a line in space has no thickness, how can I distinguish the line from its surroundings when I look at the line such that I can't see its length? After all, in three dimensional space, you can look at a line from different angles.

I still have a question though, what is the "wavelike" behavior of the electron? Here is a useful reference: http://iopscience.iop.org/article/10.1088/1367-2630/15/3/033018/pdf

Alright, thank you for pointing that out! I'll need to be more careful with what I accept as facts.

I have read the first three chapters of Griffiths. I have watched some online lectures from universities as well. If I remember correctly, decoherence is equivalent to wave function collapse. This decoherence, which is a consequence of measurement, causes a particle to be observed. In the...

Double-slit experiment. Sorry for the confusion. I have David Griffith's Introduction to Quantum Mechanics.

I am currently learning QM on my own, yes. Maybe that statement would make more sense in the context of the double slit experiment for electrons. If one electron travels through a double slit diffraction grating, one of the conclusions from that experiment is that the electron interferes with...

I have in mind the state of a free electron as it travels through space. Such an electron would be in superposition with itself, right?

I am comparing the particle version of an electron to the electron in a superposition of possible states. The particle is assumed to be concentrated in one region and not in a superposition, and the particle has experienced decoherence. On the other hand, the electron described by superposition...

Does a superposed state of an electron exist over a larger amount of space than the state of an electron as a particle?

Suppose there is a solenoid near an accelerating electron. The electron must create a changing magnetic field. By Lenz's law, an emf is induced in the coil. One question is, how *fast* is the emf induced in the coil? Is the emf just there instantaneously or does it take time to formulate? And...

Great, thank you!

I was thinking about Faraday's law, where a change in magnetic flux is necessary for an induced emf. In this scenario, I am not sure where the changing magnetic flux comes from, since the magnetic field is constant and the area through which the magnetic field lines cross is constant, even if...
