I have understood that an electron can be thought of both as a wave and as a particle. But I still don't understand why we can't give it a definite position...

So let me sum up to see if I got it right.
The electron is buzzing around and we have no way of predicting where it will be because of a fundamental law of nature (the uncertainty principle). The electron can be at any place given by it's wave function... (right?)
One final question:
Although we can't exactly "find" the electron, does it have a position in space? Logically, it seems that it should. (my logic has been known to be faulty.)
vociferous said:I think it is more along the lines of this:
"but it does not actually occupy that "location" until we measure the position (collapsing the probability wave)." .
The uncertainty in the position of an electron is a fundamental property of quantum mechanics. According to the Heisenberg uncertainty principle, it is impossible to know both the exact position and momentum of a particle at the same time. The act of measuring the position of an electron changes its momentum, making it impossible to determine its exact position.
No, we cannot know the exact position of an electron due to the uncertainty principle. The best we can do is determine the probability of finding an electron at a certain location, but we can never know its exact position.
The uncertainty in the position of an electron has a significant impact on its behavior. Since we cannot know its exact position, we can only describe its behavior in terms of probabilities. This leads to the wave-like behavior of electrons, where they can be found in multiple places at once.
Yes, the uncertainty principle has many applications in technology, such as in the development of quantum computing and nanotechnology. It also helps us understand the behavior of particles at the atomic level and has been crucial in the development of modern physics.
No, the uncertainty principle only applies to objects at the atomic and subatomic level. The effects of uncertainty are not noticeable at the macroscopic level, so it does not apply to humans or other large objects.
