Heseinberg Uncertainty Principle

In quantum mechanics, the Heisenberg uncertainty principle states by precise inequalities that certain pairs of physical properties, such as position and momentum, cannot be simultaneously known to arbitrarily high precision. That is, the more precisely one property is measured, the less precisely the other can be measured.

Okay screw that shit, I copied and pasted that from Wikipedia.

From my pile of lecture notes:

Heseinberg uncertainty principle states that it is impossible to know the exact momentum (impulse) and position of an electron within an atom simultaneously.

Seriously, if its impossible to know then why the heck did this idiot wasted his time creating some equation for us students to memorize?

Eff Chemistry!
