Uncertainty principle is the inherent property of a quantum particle. It Doesn't depend upon any observer or interaction with photon. In fact, a quantum particle itself Doesn't know the exact position and momentum at a particular time.
For better understanding, we have to learn Dirac-delta function, given by P. A. M. Dirac.
Simply, the standard deviation in position multiplied by standard deviation in momentum is grater than or equal to reduced Planck constant upon two.

Simply put: you cant measure the exact position and velocity of a subatomic particle at the same time because while you r measuring it, the act of measuring would already have changed the position or velocity of said subatomic particle, rendering it impossible to know its original position or velocity. Why the subatomic particle behaves as such is because it exists in state of probability rather certainty.

In my college, sir explained this with the help of a ceiling fan. He told us to look at the fans blade when he switched on/off the fan.
Particle nature: when it is switched off
Wave nature: when it is switched on

this is relevant and can explain protons and electrons in an atom because they attract each other and as they attract each other they gain speed because they become more and more attracted to each other!

If we could know EVERYTHING about physics, reality, and math, magically, could we calculate everything from the big bang outward; with perfect understanding, is it theoretically possible?

Went over my head, But looks to be a cool concept. Glad that I didn't pick psychics in the first place. Wouldn't have been able to live with all this uncertainty in my life.

Oh wow. Now I understand wjat uncertainty principle is. I just watched half of the video, but I got it all. Thnks Ted Ed. For this wonderful video.
Ted x is so Great.

Watch it at half the speed keep pausing to ensure you got the parts. you will understand.
Atleast it is easier to ubderstand that way.
Atleast the logic of it.
