Hwy Einstein never accepted Heisenberg's uncertainty principle as a fundamental physical law ???

Expert Solution

Einstein's never accepted Heisenberg's Uncertainty Principle, which states that for an arbitrary accuracy it is not possible to measure both the position(x) and the momentum(p) of a particle simultaneously .

But Einstein's said If someone measures the position of a particle, the particle is disturbed, so its momentum changes. If it's impossible to measure those two things at once, how can they be defined together?

In 1935, Einstein explain the problems with quantum mechanics which shows that how position could indeed be measured without disturbing the particle.

Further he states that Quantum entanglement of two particles which describes by quantum wave function cannot be mathematically factorised into two separate parts, one for each particle which is the important consequence and they become connected in a "spooky" kind of way which was made clear by Einstein's arguments and the experiments that followed.

Einstein, Podolsky and Rosen (EPR ) Collectively realised that in quantum mechanics which predicted entangled states of two particles which are far apart from each other does not matter but the positions(x) and the momenta(p) for two particles are perfectly correlated.

This was important for Einstein, who believed the result of anything that was done to the first particle did not have immediate disturbance to the second particle which he called as "no-spooky-action-at-a-distance". Thus,Einstein never accepted Heisenberg's uncertainty principle as a fundamental physical law .

One form of the Heisenberg Uncertainty Principle is ΔxΔpx ≥ h/4π, where Δx is the uncertainty in the system’s location and Δpx is the uncertainty in the system’s momentum along the same coordinate axis. Use this equation to show that exact knowledge of the system is not possible.

Use the Heisenberg uncertainty principle to estimate the uncertainty in momentum resulting from confining an electron...

Use the Heisenberg uncertainty principle to estimate the uncertainty in momentum resulting from confining an electron to an atom (~10-10 m) and to the size of an atomic nucleus (~10-15 m). Calculate the corresponding uncertainty in the energy (in eV) of the confined electron and briefly comment on the physical implications of your results.

The principle of the separate legal entity has been considered as the most fundamental principle of modern corporate law. This independence or distinction is not a new concept as it forms the backbone of the corporation’s legal issues. It is argued, however, that the sanctity of the principle of corporate veil principle is only drawn under compelling Critically analyses the above statement in light of recent development of cases in the commonwealth jurisdiction of Malaysia and United Kingdom.

The law of mass conservation is another fundamental law in chemistry. this law states that matter can neither be created or destroyed, which means that in a chemical reactions where all the reactant is converted into product, the mass of reactant must be equaly equal to mass of product produced. A) consider 2 precipitation reactions B) experimental procedure that you can use in lab C) contemplate how you might visually represent this data (I) what variables might you need to...

One of the aspects of the uncertainty principle, is that in making measurements, one changes the system being measured. Give an example of this in your everyday existence.

The most basic explanation for the Heisenberg Uncertainty Principle is that the momentum and position of...

The most basic explanation for the Heisenberg Uncertainty Principle is that the momentum and position of a quantum particle is not very distinct when an attempt is made to measure them together. But what is it that causes the uncertainty? Because if there is no change in the momentum, then it would be the same as measuring the two separately. So what causes this change in the instantaneous perceived momentum. A change in mass? Velocity? Or net composition of the...
