What is the Heisenberg Uncertainty Principle: Explained in Simple Words

Ғылым және технология

Heisenberg’s uncertainty principle says that if we know everything about where a particle is located, we know nothing about its momentum. Conversely, if we know everything about its momentum, then we know nothing about where the particle is located. In other words, this principle means that we cannot measure the position and momentum of a particle with absolute precision or certainty.
But waves, as you know, don’t exist in one specific place. However, you can certainly identify and measure specific characteristics of a wave pattern as a whole, most notably, its wavelength, which is the distance between two consecutive crests or troughs. Particles that are as small or even smaller than atoms have large enough wavelengths to be detected, and can therefore be measured in experiments.
Thus, if we have a wave whose wavelength and momentum can be measured accurately, then it’s impossible to measure its specific position. Conversely, if we know the position of a particle with high certainty, then we cannot accurately determine its momentum. This is what Heisenberg’s uncertainty principle is all about.

    @@MRCAB Actually, saw that video clip again. It is actually wrong at around the 2:00 mark. It says a photon used to probe a particle imparts some energy that changes its trajectory and that's why it's impossible to know it's position and momentum simultaneously. This is wrong, and its something that's repeated over and over again. It's not that bouncing a photon off a particle "disrupts" it so that it's position and momentum can't be determined. Because if this were true, then it means a particle has a definite location and momentum so long as you don't probe it with a photon. This is not what quantum mechanics says. Quantum mechanics says a particle has no definite position and momentum to begin with. The video clip is talking about "measurement" uncertainty. Quantum mechanics says the uncertainty is there even before you measure.

    It's not that we're chasing down a physical impossibility here, we are still learning about our world and what part quantum mechanics actually plays in it. For me I've had to scrub that Schrodinger's Cat is no longer theoretically correct anymore and needs to be rewritten. At the time of Schrodinger, the Universe is all that we knew, but now that has changed, which therefore means that Schrodinger's Cat theory has changed as well. If we now have to accept the "Multiverse" then logically we would have to re-write, both Schrodinger's Cat' and "Super Position" because it would automatically point us towards "Hyper Position" of which no one has written any rules about. Aside from me who I know has coined the new phrase. Hyper Position has to exist based on the Multiverse, being more than one universe, in any given position. We would also have to add ten to the power of infinity for the multiverse to make any sense, and with that given it then changes our understanding of "Super Position" to allow us to go up another level to "Hyper Position" which might have far more levels that we've yet to discover in our understanding of Quantum Mechanics which for us is still a relatively new concept. Having said that it does propose that all may not be lost in terms of giving up anything here, but a theoretical adjustment that would allow us to embrace "Hyper Position" which is obviously the next level up even though it's not been thought of as far as I'm aware. My other gut instincts is that Hyper Position ticks all the boxes when we bring in wave function, and allows not just duality relative to Super Position alone, but takes us up a level to hyper which will throw us into the dark so to speak again. In terms of incremental steps mega position would have it's place but beyond that hyper would be up there on the list. Maybe I just missed a step, and it's that simple or obvious.

    Great video but you only highlighted the quantum mechanical implications and left out perhaps the biggest key to understanding this principle intuitively which is the relativistic implications. Not only does the energy of the photon affect the particle you’re attempting to measure but it also warps the literal fabric of space surrounding the particle. So much to the point that if you tried to measure something the size of a Planck length the energy of the photon required would exceed the Schwarzschild radius, collapsing in on its own energy into a black hole.

    I suppose that is it suffice to say that if you are trying to get the momentum or the speed of a particle by observation it becomes uncertain. But if you assume that same particle is left in a theoretical sandbox of no energy you can assume that it has a particular momentum and speed.

    Don't worry the first part is completely made up. There's no theory that it is a photon causing particles to change behaviour and the idea that its a Newtonian physics like collission with a photon is ridiculous. They've proven long ago that the superposition doesn't collapse until an actual human-being has seen the outcome. There are no photon particles being fired at a particle and this somehow telling us where it is or it's velocity. We can only detect particles that small indirectly by their effects on a field - nothing is fired at the particle. Heisenberg's principal was to do with wave-function collapse and he never tried to explain the fundamental mechanism at play, nor suggested it was due to a photon (which again not even part of the experiment) had influenced it via newtonian physics. I'm not sure where this guy got his info but it's certainly not from anyone even remotely familiar with physics. It's also pretty insulting to Heisenberg that his name is being associated with such a ridiculous idea.

An even the idea of one particle at different locations at same time is also vague. Coz quantum particle has one single state Always Always.

If you reveal the eye it can be both right and wrong and only when you look will it either be right or wrong (exclusivity or); it cannot be both at the same time. If it is right then we know for a fact that it is definitely not wrong and vice versa. You are trying to make an analogous example about quantum systems and failed doing so.

    Your whole argument is based on the assumption that we know what a particle is. Also there is an assumption that wave/particle duality makes sense. It is very much like Jesus is God duality. There are particles and there are energy waves. All particles have associated energy waves. Hiwever first explain what a particle is before you make any other claims. No one knows what particle is. That protons for instance. The most recent description of a protons mass says the mass comes from the energy of the strong force holding the quarks in place. No one has the faintest clue what a quark is. No one has the faintest clue what the strong force is. Even electromagnetic forces are fundamental not known. Scientists describe fields and charges without actually knowing what is a field is or what a charge actually is. Then your descriptions show bundkes of curly lines that supposedly demonstrate wave particle duality. This diagram is just plain silly. How are the waves within each blob interfering with other waves whether in the same blob or with other blobs. I summarise by saying the mathematics of continuous functions cannot hope in any way to describe the discrete or quantum, except at a statistical level of probability.

    Sorry but the first part of this video is completely inaccurate. This theory of some rational explanation to wave-particle duality such as a photon interfering with the path of a wave has never been accepted by the community nor was it ever a theory of Heisenberg's let alone the basis of his Uncertainty Principal. Detectors do not fire photons at particles in order to measure their velocity. That is not how they work and particles do not follow Newtonian physics at the quantum scale, they are measured indirectly by their effects on the field and this is detected by detectors with incredible sensitivity. There are numerous theories as to how something can be both a wave and a particle and exist in multiple positions simultaneously. And many more that try to explain how a particle knows its being observed, but photons colliding with the particle is not even consistent with the methodology and can be ruled out.
