In many cases the particle interpretation is perfectly right. It's known as the path integral formulation. Basically, what you do is consider that when a particle travels from point $A$ to point $B$, it goes through every possible trajectory (including back and forth in time) all at the same time! In fact, every paths have the same probability, they just ...

@Anna_v posted an excellent answer, but I would like to add some figures. What is essential for understanding the wave-particle duality, is that: Microscopic objects such as electrons are always detected as particles. The wave nature becomes apparent due to interference pattern. For your convenience I present here two figures from the book by M. Namiki ...

The image of the car is blurred because it's taken at a low shutter speed. But it nothing like a wave, if you used a high shutter speed you would see the car as if it were at rest. The wave particle duality is not at all related to speed.

No. You quantize strings using the same methods as for other classical theories, but these methods are postulated, so you can't use this to explain anything. There is also no such thing as wave-particle duality, that's a terribly out-of-date term. We have neither particles nor waves, but instead wave-functions and operators that correspond to observables.

Lets take this a step at a time: What is a wave? In everyday language a wave is a disturbance in air, liquid or solid that has a periodic appearance in space and time, i.e. the shape repeats. The shape of waves in water is most evident, and it was found that they can mathematically be reproduced by sinusoidal functions. Differential equations were ...

I do not think so. As a matter of fact strings must be "quantized" to produce "quantum" physics. So the quantum structure (including all apparently weird things) is assumed a priori even dealing with strings. It is deeper than string theory.

There have been experiments with single photons at the time which display interference even after knowing which slit the photon went through. I do not think that the disturbance of the field by a single electron would be detectable, including correlated with which slit it went through. Possibly a variant of the experiment in the link, using entangled ...

The confusion comes because you are thinking of probability waves, which is what the interference pattern from elementary particles through the double slit experiment are, as if they are classical waves. Current day physics accepts that the fundamental framework of nature is quantum mechanical. Classical mechanics, classical electromagnetism are emergent ...

If E represents only kinetic energy and v is small compared to the speed of light then this is ok. However, the electron mass is already known, why calculate it?

I think is a misinterpretation of the wave-particle duality. We always detect electrons as particles, but they have an associated wavefunction $\psi(\vec{x},t)$, which its square gives you the probability of finding the electron at each point. So in the double slit experiment, the wavefunction (probability wave) diffracts and you see that electrons form ...

The particle/wave duality at the micro framework where quantum mechanics has to be used does not describe "particles" as billiard balls, nor "waves" as energy/mass waves. Electrons when displaying "particle" properties are measured at a specific (x,y,z,t) but the values in space are indeterminate according to the Heisenberg Uncertainty Principle. The ...
