Why Heisenberg uncertainty principle is applicable to only microscopic particales
Answers
The premise of the question is false. Heisenberg’s uncertainty principle operates at all scale levels. As does indeed ALL of quantum physics. For example, an entire sugar cube could be quantumly entangled with another sugar cube. Hell - a whole frickin’ galaxy could. If I’m not mistaken, we have successfully entangled crystals that are (barely) visible to the naked eye.
It’s just that a lot of these phenomena are only easy to observe with very few particles, etc.
Some of these phenomena ARE readily observable at macroscopic scales. For instance, conductors conduct due to quantum physics. (Because there’s a set of electron energy levels that are close together, allowing electrons to make quantum leaps rather freely.)
As far as what we measure mechanically on a macroscopic scale, however, we are measuring the average of a truly enormous number of particles.
Answer:
Explanation:
Heisenberg's uncertainty principle states that the momentum and precision of a particle cannot be simultaneously measured with arbitrarily high precision.
This is not something can that be put on the innacuracy of the measurement instruments, nor on the quality of the experimental methods; the uncertainty comes from the wave properties inherent in the quantum world.
Heisenberg Uncertainty Principle Formula
Quantum mechanics is the discipline of measurements on the minuscule scale. That measurements are in macro and micro physics can lead to very diverse consequences. Heisenberg uncertainty principle or basically uncertainty principle is a vital concept in Quantum mechanics. Uncertainty principle says that both position and momentum of a particle cannot be determined at the same time and accurately. The result of position and momentum is at all times greater than h/4π.
