The author of the article «Seeing an electron» laughs at the Schrödinger equations, on which quantum mechanics is built, and according to which, the slower an object (photon, electron, star, person, etc.) moves, the more it is smeared into infinity … quantum mechanics, this nonsense is «overcome» by the postulate that as soon as the «observer» looks at this object, he is immediately fixed somewhere.
A little more nonsense from quantum mathematics.
If the electron really could pose as a wave, then it could be easily seen. Especially if the photon was also a wave. Since the wavelength of an electron depends on its speed, it would be possible to accelerate, well, or slow it down to, for example, a speed of 1213.18 m / s and admire the «electrons of the visible range». That is, with a wavelength of 6 * 10 ^ -7m.
But the electron as a wave function is just a mathematical concept, and our senses, and even instruments, do not perceive mathematical concepts.
Yes, and there is nothing to perceive. Although an impulse from classical physics (p = mv) is used to determine the wavelength of a particle, such a particle has no mass. First, because the mathematical concepts of mass do not have by definition. And secondly, since a wave physically cannot be stationary, then, whatever one may say, nothing has rest mass. And the rest mass has no momentum. Thus, Einstein, with his cunning twist, with this very mass of rest, drove us a little into a paradox. However, this does not in any way prevent the use of the classical impulse from the paradoxical use. Moreover, the functions are all the same for this.
Let us recall that a photon with mass did not fit into the great formula of relativistic energy from a relativistic impulse, therefore it is designated as massless. True, he did not fit into it massless, therefore this formula does not apply to photons. In this formula, in the same way, not a single particle that has any speed different from the speed of the system can fit. That is, any moving particles are also massless.
Again, each electron has the entire wavelength range at the same time. Let’s say the electron has the same 1213.18m / s relative to us, but moves in the same direction as the Earth relative to the Sun. And relative to the Sun, its speed is of the order of 30213.18m / s and the wavelength
You can choose any wavelength, just remember that the lower the particle velocity, the greater the phase velocity of the wave. That is, the phase velocity is different at once.
The longest electron wavelength, one might even say — «Planck» will be for the electron, which moves with the lowest possible speed. This speed is based on the Planck length (distance) — 1.616 * 10 ^ -35m, and naturally, in one second. Total: 1.616 * 10 ^ -35m / s.
And the more static the electron, the more difficult it is to find its coordinate. And you probably thought it was the other way around.
