Question

Can any one explain the Heisenberg Uncertainty Principle in the simplest ways?? Thank you so much.

Answer 1

If you know the exact position of the particle, you won't be able to know the exact speed of that same particle

Explanation:

This is kinda hard to explain but I'll try to do it in the simplest possible way.

Imagine a baseball game. Now imagine the pitcher throwing the ball as hard and as fast as he could towards the catcher.

In order to know the exact speed of the thrown ball, you might need to use a speed gun. In order to know the exact position of the ball at a given time (say, 2 seconds after it was thrown), you might need a camera and some high-tech equipment to freeze the image frame-by-frame. But you cannot use the speed gun while the photo is frozen and vice-versa.

This is how the Heisenberg Uncertainty Principle works. If you can determine the speed, then you cannot possibly determine the exact position of the particle (since in particles, there is no replay button, unlike in a baseball game). At the same time, if you can determine the location of the particle, it will too late for you to determine the exact speed (again, no replay button).

Hope this helps. :)
